ive had a 04 RX8 since 2005 but stopped driving it in 2010, so its been sitting in my garage collecting dust. You and Driven By Madness have inspired me to give it some TLC and get it back on the road... Cheers for that... =)
Probably the best explained videos on YT, with good reasoning about problems and failures. Recently i got my RX-8 and i noticed the exhaust has a little hiccup, so i got the LS conversion kit, let's see how that will work out. Thank you !! Keep up the good work 😊
Awesome video. Thanks for the upload. The RX-8 actually does have a gas cap holder that is built onto the gas door itself. It's kind of awkward to use, but either way, I love that Bennet Built version so I'm buying it anyways.
After reviewing your video about the installation of the Sohn adapter, I purchased mine and installed smoothly by watching your video, thank you so much! Now I’m going to buy the coil set, too. Is it still running perfectly?
I think the reason for the spacers holding your coils up away from the mounting plate is to make arcing from the coil to the plate less likely. This is just my theory but if you look at bad coils they do seem to look like there has been some high voltage arc over. I was thinking of putting under the coils some form of insulator rather then just space them further away. I don't really the voltage that the coils generates but it is very high voltage and I seen how far a spark can jump and how it can blast through things. I did an experiment with a 10,000 Volt transformer and blew holes through a model airplane (Plastic) then tried a drinking glass (Which is a really good insulator) and after holding the lead against the glass for a while did punch a hole through it. So the plastic glop on the bottom of the coils might be a pretty good but with spark voltage? Moving that base further away is a smart move. I don't see how any heat from the coil is drawn off by the plate so... My two cents worth.
Thank you very much for recommending of the Bennett Built kit . Received the kit just before Xmas and have just this minute finshed the test drive OMFG . it is a 4 port in front of a auto so maybe givong out 155 kw I was vary disappointed with my RX 8 butt now with this one mod it is a new car . Thank you again
Those look exactly like the ones I built :) genuine D585 coils, conversion harness, and MSD superconductor wires (could be mistaken, but msd boots look a helluvalot like that). All quality parts, you will be pleased. Your bracket is much nicer than mine (threaded rod) though
I feel you, accessing the bolts for the bracket are a bitch. Mazda's doing. The upgrade is completely necessary tho imo. Nice 8, will be interesting to see how it stacks up long term against the other great cars you've daily'd
Great video thanks so much for the info! I have a rx8 04 with 84,400 miles had purchased used with 51,100 about 3 yrs ago. I replaced the starter back in 2016 (not a 2.0 kw that I hear might be better) and alternator (remanufactured from dealer 4/17). I had some starting issues and cell codes that came up 1/5/17 P0443 purge valve and P0302 miss fire in cylinder 2 and my engine light was on prior to my inspection due 1/17. Thus my reason for getting all of this done including new ignition coils,spark plugs and vapor canister valve or known as Canister Purge Soleniod. I just had my car serviced at dealer (Last week 12/17) for recall 1017e of fuel tank leak issue and had fuel ring and gasket and fuel pump etc and they also did the other recall 1117e for 04 rx8 remove and replace both lower arm ball joint and front lower control arm. Now yesterday (after having car sit 2 days due to 2 snow events here in Philly) I started the car after 2 or 3 tries and after not having any cell codes or engine light come on had the engine light glowing. I took it to the same place that serviced my car back on 1/5/17 thinking maybe was spark plugs and ignition coils and purge solenoid etc and he pulled a code P2070 claiming was IMT Valve Stuck Open and not the other things mentioned related to all the ignition work I had done. I say all this because I have a 24,000 miles or 2 yr warranty covering the parts and labor they gave me free with the work done on the car 1/5/17 with Confidence Plus North American Warranty. I called them and they assured me they would honor the repairs as long as 25 miles from service performed on car. But here I sit with this NEW code and wondering how I RESOLVE this?? I had the work done back on 1/5/17 at that time with 75,760 miles and now have 84,400 as mentioned not even 10,000 miles since having everything replaced! I TRULY love the rx8 and would like to keep it but now with all of this and facing my current inspection due 1/18/18 I just don't know how much more I can do?? It feels like a repetion of what I had the year prior almost same time and gotta think having the RIGHT coils, spark plugs and such would have to make a BIG difference in the performance of the car? I thought of BHR or comparable like you have used thinking it has to be better than what I have? I have tried to keep the car as best as possible using Continental Extreme Contact 225/45/18 tires and really kept it otherwise stock (auto with upgraded leather seats and moonroof etc) I know the warranty I have after speaking to them on phone mentioned they would cover the $847 I spent at that previous shop. Do I take it to another shop 25 miles away and see if they can RESOLVE this? I just know it has to be a "good thing" to have this done and want to get as much bang for the buck out if this warranty as possible. They even said you can go to a dealer and they will replace the ignition parts etc but if I go there then going forward I would be under dealer warranty going forward. I guess need a little guidance best way to handle this?? I should mention I have not had a Compression test done and wondering is THAT my next step before doing anything else?? Any suggestions would be greatly appreciated! I really would love to keep the car but I'm just wearing thin on how I can DO THIS and not go broke in the process! I mean is it just ditch everything and get a 09+ rx8 that is sorted out better than what I'm dealing with now?? I've already dumped heaps into this so far. I'd love to get to a conclusion and know car is right! Appreciate any help that can be provided! I live in NE Philly does any one know a reputable rx8 shop that works just on rx8s I can take it to?? Trying to be optimistic here? Thanks, Nate Can reach me at natebmw320i@gmail.com (Had a 320i way back in 1981 kept the email. Heck that car had 175,000 miles before I got rid of her!)
The P2070 code would mean that your SSV valve is stuck. I have seen some people get false positives for this. I would reset the ECU either with a scanner or by disconnecting the negative battery terminal (remember disconnecting battery will give DSC lights until the yaw sensors calibrate again) and see if the code comes back. If it does, I would look into cleaning it either yourself or a shop who is familiar with this service. Some will try to sell you a new intake manifold.
Garage Quinn Motors Hey thanks for the reply! I did have the shop I originally took to back on 1/17 reset it for me yesterday and so far no code showing. But I guess if does come back have shop clean it as you said. Do you know any reputable rx8 shop that work JUST on rx8s in NE Philly?? I also found out when had my car serviced recently at dealer for the recalls I had that they saw my motor mounts are bad. Car does have small vibration on dash when I come to a stop but during drive seems fine. Any help appreciated?? Do you think a Compression test would be wise also as have starting issues both hot and cold? Again thanks for any help! Nate
You're welcome. Unfortunately, I do not know of any shops in PA to recommend. Why did they say the motor mounts are failed? I would look at how much the motor shakes while running at idle. Dealers like to recommend stuff when you don't necessarily need it. If you are having hot startup issues, then I would run a compression test on the motor.
Garage Quinn Motors Right I agree! Yeah well was my fault as I mentioned to them the vibration I had was with my dash when idle or stopped at a light..then they either looked or tried to sell me an upgrade? Car rides fine to me otherwise no major shaking while driving I can tell. They did say that it's there and if I didn't do with them would not pass inspection! I will go somewhere else and not mention anything see if they find anything? Again thanks for advice!
My 2004 RX8 had these symptoms last week (down on power, cat glowing red hot, car refusing to start and idling crazy low to the point that it barely feels like its on at times). Had an engine rebuild back in 2017 and have barely done 10,000 miles since then. I am going to replace the spark plugs , coil packs and leads as I was planning to do that anyway and the oil metering pump as I am getting error codes P0302 (2nd Rear Rotor Misfire) and P01687 (Metering Oil Pump Malfunction) I hope this fixes it but for now I am confide to the motorbikes
My ignition coils failed at 30K miles . I had them rep[laced with OEM factory Mazda coils several years ago. When the ignition coils failed the cat failed also . Fortunately I was able to get Mazda to replace the CAT under warranty. I now have 60K miles on my 2006 RX8 GT. Do you still think this ignition coil replacement is the best? I have seen many others recommended. Thanks in advance.
The Bennett Built site says "To see the greatest benefit from this coil conversion we recommend that the ignition coil dwell setting be adjusted using a Cobb access port or similar tuning method." My question is did you adjust the dwell setting???
I did not adjust dwell yet, have been running these with the stock dwell settings no issues. I was going to try bumping dwell when I go to the dyno to see if it makes any difference.
Really good job man this video is very entertainment.... I am about to buy an Rx8 but I am of scared for engine failure.... how much compression your rotors have right now? How many miles is safe to say that a, well maintained, rx8 goin to make before the engine failure?
ΕΥΛΟΓΗΤΟΣ Well sir. It's not that simple. The miles dont matter as much as the care does. Not a lot of people cared for thier rotarys because they didnt even know it wasnt a piston engine. I recommend reading through RX8club before purchase. One thing to remember is Rx8s dont have a lot of low end torque.
Thanks man. I'm not sure where compression in my motor is, but there is no indicators that it is unhealthy. I agree with Hating Finding a Username, the maintenance and care is more important than the mileage. A properly maintained Renesis should do 200k+ miles. If you are worried about fixing the niggles and reliability, I'd recommend searching for a Series 2 car (09-11) as they had most of the issues sorted with those cars. Mazda also gave every car an 8 year 100k mile engine warranty, so the 2010-2011s would still be covered under that factory warranty.
Hey Quinn! My rx8 is having a funny subliminal knocking sound sorta like krongkrongkrongkrong during startup for 15-30 seconds when the car is left cold for 2-3 days. Would it be a case of bad ignition coils ? I have replaced plugs, starters, checked fuel pump, fuel injectors and even the OMP. Any thoughts ?
My experience with bennit built coils isnt great... ecu is throwing c.e.l for all coils.. it does start beter and run well under 6000rpm but wont rev over 6k. Multiple emails to bb with no reply. Id pay the extra and go bhr
Hi there...loved all the videos on RX-8. Installed the Bennett Built on my JDM RX-8, right hand drive. However encountered error message on my dash...ABS and CEL light. Do you know what’s the issue? Could it be a different installation method for JDM RX-8? Thank you!
@@TheSlipAngle Hi there...Sorry haven't been back for a while till now...the error message captured from the fault report is showing DTC: P0351~P0354 - Ignition Coil A~D Primary / Secondary Circuit. Any idea what is the the root cause? It was installed by a reputable mechanic... :-)
Hey. Finally picked up an rx-8 04 w 52k. Immediately going to get into reliability mods. About to order coils and am on the fence with the BHR and Bennett built. I know this is a common question but I just wanted to know how they are treating you so far?
I mean for the price of BHR coils I got the Bennett built, a new starter motor, and the sohn adapter...can't really beat that. Will be viewing your video on the sohn adapter as well. Thanks for posting. I feel like we are going for the same set up!
Quick question though. I know eventually I'm gonna have to ditch the cat like you said if you're doing a premix set up. I'm smelling almost like a natural gas smell while I drive. Like I open up the windows and it's very strong. Any idea?
Hi i have put in similar coil system d585 coils but car won't start, it cranks, I have even put jumper leads on it and it wont start. Do i need to reset anything? please help!
Garage Quinn Motors hi it was nothing wrong with plugs and coils, during the job pulleys were changed for billet ones and eccentric shaft plate wasn't put on that was the problem.
so i installed these coils in my car yesterday and they startup fine but i sometimes notice a little sputter here and there at idle that never happened before the installation. is this normal?should i be concerned? does the ecu need time to adjust? also i had a check engine light before the install that went away after installation. anything you may know about this ?
Hey Nick, my car has always sputtered at idle a little, even with stock ignition components. I think it is just normal. You should be able to pull the code the car was throwing, it might have been misfire codes if your old coils were on their way out. Also, yes you can reset the ECU and let the car relearn with the new coils and see if that improves anything for you.
The biggest factor for me was the price. At the end of the day, spark is spark. As long as you have coils that can produce a strong enough spark and recharge quickly enough for the next spark needs to occur, then you'll be fine. In the Miata world, there is a common belief that you need to switch to coil on plug (COPS) because the factory coils are inadequate. Let's just say my turbo 254 whp Miata and 185 whp all motor Miata are still using factory coils and OEM NGK wires with no issues blowing out the spark. Rotaries have a little more demand for spark, but there is no magic coil out there. The only concern with using stock coils is the short lifespan, however that is supposed to be resolved now with the revision 'C' coils that are available.
I don't know what the life expectancy is, other than it should be much longer than the OEM units. I only have about 6k miles on these coils now, but so far no issues.
I’ve been trying to contact Bennett built performance for the past couple of weeks and I haven’t gotten a response from them. I purchased an engine from them a month ago and I’ve tried to contact them through Facebook and also email. Can someone tell me how can I get in contact with them because that’s a lot of money I’ve just spent and I don’t have money to waste especially when it’s in the thousand range
The BHR system is almost double the cost. The GM coils and adapter pigtails are relatively cheap parts if you were to build your own ignition kit. I've gone down the rabbit hole with obsessing over ignition in the past and it doesn't lead anywhere meaningful. At the end of the day, as long as your system can create the spark needed and it is not blowing out, then there is no difference or performance benefit.
Hows that napa battery working? Is there anything special about it? Or you using it just because?... Also thanks for knowledge on the ignition coil replacement
The battery came with the car when I bought it. It leaked all over the support brace and ate the paint off of the metal, so I definitely wouldn't recommend it lol. I am probably going to move to a Shorai unit.
@@TheSlipAngle Ok. But I assume you had to adjust timing for new coils? I'm getting close to replacement in my S2 and still struggle between OEM mazda and some aftermarket ones.
@@does_not_matter_91 we picked up a couple HP increasing the dwell times but the car has a sputter in high gear 4k+ light throttle cruise so they need to be turned down a little
I am not sure. I think if you have an ECU that supports 2-step that you can tune, that would be the route to go if you want that as the LSD for LS might be assuming an LS firing order which is definitely not the same as rotary :)
I will be receiving my bennett built in a couple days, great vid, btw. Question, the original connectors to the coils, are they color coded from the factory? So you know what oem wire goes to what coil?
Well they came as advertised, no need for color coding. Just pay attention. They work great. I do have starting issues but i think its my injectors. Good luck. They worked great.
Preston Brown Thanks for replying man! Im currently on the revision c coils. Installed them @ around 35k miles, going into 88k right now. They've been great but i think im pushing it lol so its time to upgrade and be done with them. Thank you sir!
Not a problem. Keep in mind they took about a week and a half to get to me here in california. But he delivers. Also change plugs when you do the change. Good luck and let me know how it goes
Try tapping it with a hammer while someone tries starting it if you can. Alternately, I think most local auto part places will test your starter for free if you bring it to them, but I did once have a starter that passed the bench test and still wouldn't crank the engine. You can always just pick one up local and return it if doesn't resolve the problem.
I changed the starter today and it won't crank nor start. The only thing in mind now will be the grounding of the car. I do get a car with the key inside on the dashboard?
Yes, mostly in the 6-9k RPM range. I wouldn't say it is more smooth, but you can definitely feel it gained a slight bump in power, but this is most likely because my coils were crapping out.
Garage Quinn Motors Awesome! Just ordered from Bennett myself! Love your channel man!:) I have a question, I’m running cat less atm but I need to pass emissions test this spring, will an eBay cat work for the moment, like will it clean like the OEM?
I do not have any experience with the eBay cats unfortunately, so I cannot say for sure. I do have a catless mid-pipe w/ built in o2 spacer that came with the silver RX-8 I bought. I think it is eBay and I have been running that on my car. I did throw a check engine initially, but it eventually went away and never came back, so I thought that would actually pass readiness.
so ive just used an ebay cat to pass the mot (im uk) and it passed emisions beautifully but i had to reset the ecu then run the car through the driving process to let the ecu learn the new setup i can find the driving process if you need
I don't see a lot of these cars anywhere. But if I had to guess why they aren't at track days I'd say it's because they're slow and there isn't much you can do to make them fast.
Rx8's arent the quickest cars around but they're definitely not slow( especially around corners). You don't see them around often because most people are just afraid of rotary engines and the attention they require.
I think they're pretty average handling for a 3000lb sports car. You asked about the cars weaknesses before, I'd say it's biggest weakness is the competition it has. I probably wouldn't buy one as a track day car given the plethora of other cars available.
Compared to the rx7 which was 260-270hp and 2800lbs, this car was almost like a betrayal imo. Heavier, slower, taller, and from a looks stand point, i think it lacks there also. Stripping the weight off would probably give great results but that motor needs some work or a swap if u ask me, they do still handle decently and have that rotary exhaust note tho. If you ever look up Hot Version International on youtube u will see some tuning shops run the RX8 and do well, but it's quite costly.
I would say above average handling especially for its 3000lb curb weight. Rx8's are extremely underrated cars I've seen them outrun frs/brz's in autocross events. The only reason they cant really compete with the s2000 is die to their lower power/weight ratio. @ Elykus I agree that the rx7 is a beast but the rx8 is the topic on hand not the rx7 so i'm not sure why you brought it up.
Nice video but man, ditch that engine cover. Unless you drive it in the cold/winter and want to have the engine up to operating temperature faster, I've noticed my rad's fan not to spin as much as it did with that thing on even in summer with 30+ °C ambient temperatures. After long use in the summer in the past I've heard the fan to spin for a long time (the first time I got the car, it spun for like almost 10 minutes!), without it in a comparable climate, it spins for much less time than with it installed. Engine cover.. it's just a cosmetic thing.
Yeah the Renesis does it's own weird thing depending on where you are. This is a pretty good read: www.rx8club.com/series-i-tech-garage-22/weird-renesis-ignition-tech-info-17108/
Corrie Jacobs what are you talking about? He’s linked the kit in the description. They are ls2 coils with an adapter for the stock harnesses and leads.
ive had a 04 RX8 since 2005 but stopped driving it in 2010, so its been sitting in my garage collecting dust. You and Driven By Madness have inspired me to give it some TLC and get it back on the road... Cheers for that... =)
How’s the car running?
why would you stop running it for that long?
Probably the best explained videos on YT, with good reasoning about problems and failures. Recently i got my RX-8 and i noticed the exhaust has a little hiccup, so i got the LS conversion kit, let's see how that will work out. Thank you !! Keep up the good work 😊
Curious to know if the new coils got rid of that hiccup?
I got the same Bennett Built coil kit and I'll comment again after install!
Update
It works really good, more power and seems solid!
Awesome video. Thanks for the upload. The RX-8 actually does have a gas cap holder that is built onto the gas door itself. It's kind of awkward to use, but either way, I love that Bennet Built version so I'm buying it anyways.
Thank you!

Awesome man, I am really glad to hear! Yup, still running excellent!
Having a possibility misfire issue with my coils hopefully these will sold the issue and have my Rx8 running again
I've heard people say they can't get ahold of Bennett. If you can't source them just get new OEM factory units.
God damn this is the first rx8 video that was super super super helpful great stuff
Thanks Kavi!

Did you adjust the dwell times to get the improved performance benefits? If so can you share the table values?
really looking forward to this. i am so tempted to jump into an rx-8 but have the worry of the misnomers of the rotary.
You could spring for an S2 model (09+), which has most of the issues sorted out already.

The Bennett Built site says "To see the greatest benefit from this coil conversion we recommend that the ignition coil dwell setting be adjusted using a Cobb access port or similar tuning method." My question is did you adjust the dwell setting???
I did not adjust dwell yet, have been running these with the stock dwell settings no issues. I was going to try bumping dwell when I go to the dyno to see if it makes any difference.
Garage Quinn Motors That will make a great video! Hope you show how to adjust dwell time with mazdaedit. Keep up the good work! Love your videos.
I have used the Revision C OEM coils and never had a issue.
Anyone got the lastest BBP igniton kit with the D585 coils ?
I'm about to upgrade but don't want to get the AEM Kit since it's twice the price
Really good job man this video is very entertainment.... I am about to buy an Rx8 but I am of scared for engine failure.... how much compression your rotors have right now? How many miles is safe to say that a, well maintained, rx8 goin to make before the engine failure?
ΕΥΛΟΓΗΤΟΣ Well sir. It's not that simple. The miles dont matter as much as the care does. Not a lot of people cared for thier rotarys because they didnt even know it wasnt a piston engine. I recommend reading through RX8club before purchase. One thing to remember is Rx8s dont have a lot of low end torque.
Thanks man. I'm not sure where compression in my motor is, but there is no indicators that it is unhealthy. I agree with Hating Finding a Username, the maintenance and care is more important than the mileage. A properly maintained Renesis should do 200k+ miles. If you are worried about fixing the niggles and reliability, I'd recommend searching for a Series 2 car (09-11) as they had most of the issues sorted with those cars. Mazda also gave every car an 8 year 100k mile engine warranty, so the 2010-2011s would still be covered under that factory warranty.
Good job! You convinced me to get these coils with my tax money. Thanks for the video.
Melmo Deltron how have they treated you so far?
Hey Quinn! My rx8 is having a funny subliminal knocking sound sorta like krongkrongkrongkrong during startup for 15-30 seconds when the car is left cold for 2-3 days. Would it be a case of bad ignition coils ? I have replaced plugs, starters, checked fuel pump, fuel injectors and even the OMP. Any thoughts ?
Without hearing it in person I can't really speak for what I think it may be
My experience with bennit built coils isnt great... ecu is throwing c.e.l for all coils.. it does start beter and run well under 6000rpm but wont rev over 6k. Multiple emails to bb with no reply. Id pay the extra and go bhr
Hi there...loved all the videos on RX-8. Installed the Bennett Built on my JDM RX-8, right hand drive. However encountered error message on my dash...ABS and CEL light. Do you know what’s the issue? Could it be a different installation method for JDM RX-8? Thank you!
Are you sure you have the spark plug wires in the correct order? What is the code for the CEL?
@@TheSlipAngle Hi there...Sorry haven't been back for a while till now...the error message captured from the fault report is showing DTC: P0351~P0354 - Ignition Coil A~D Primary / Secondary Circuit. Any idea what is the the root cause? It was installed by a reputable mechanic... :-)
Just subscribed. Love your videos. Just bought an 06 Shinka and need to do all this stuff.
Over two years now on your Bennets, so how are they doing ?
Thank you! Still holding up!
Man, you have to put a CAI on the RX-8. It really transforms the experience.
It's coming :)
Very true. This vid just added a new coil system to the top of my list. Right next to an ingen ram intake I've been wanting for my 8 👌
Not to bust your nut, but the stock airbox *is* a CAI. You will not gain a single horsepower changing the airfilter system.
Do you have the link for those ignition coil to order it? Price?
good job
Thank you!
Hey. Finally picked up an rx-8 04 w 52k. Immediately going to get into reliability mods. About to order coils and am on the fence with the BHR and Bennett built. I know this is a common question but I just wanted to know how they are treating you so far?
No issues with the Bennett units 👍
I mean for the price of BHR coils I got the Bennett built, a new starter motor, and the sohn adapter...can't really beat that. Will be viewing your video on the sohn adapter as well. Thanks for posting. I feel like we are going for the same set up!
Quick question though. I know eventually I'm gonna have to ditch the cat like you said if you're doing a premix set up. I'm smelling almost like a natural gas smell while I drive. Like I open up the windows and it's very strong. Any idea?
What are you running now still same if so bro how are they now. Would you still recommend these looking to get some
Still running these. Any of the conversions should be good
Hi i have put in similar coil system d585 coils but car won't start, it cranks, I have even put jumper leads on it and it wont start. Do i need to reset anything? please help!
Double check the wires and make sure they are connected correctly. What brand of D585 coils is it?
Garage Quinn Motors hi it was nothing wrong with plugs and coils, during the job pulleys were changed for billet ones and eccentric shaft plate wasn't put on that was the problem.
hey which battery terminal did you ground the coil pack too?
That would be ground the name should give it away.
so i installed these coils in my car yesterday and they startup fine but i sometimes notice a little sputter here and there at idle that never happened before the installation. is this normal?should i be concerned? does the ecu need time to adjust? also i had a check engine light before the install that went away after installation. anything you may know about this ?
Hey Nick, my car has always sputtered at idle a little, even with stock ignition components. I think it is just normal. You should be able to pull the code the car was throwing, it might have been misfire codes if your old coils were on their way out. Also, yes you can reset the ECU and let the car relearn with the new coils and see if that improves anything for you.
What is the difference that resulted in you choosing this over the SakeBomb and BHR coils?
The biggest factor for me was the price. At the end of the day, spark is spark. As long as you have coils that can produce a strong enough spark and recharge quickly enough for the next spark needs to occur, then you'll be fine. In the Miata world, there is a common belief that you need to switch to coil on plug (COPS) because the factory coils are inadequate. Let's just say my turbo 254 whp Miata and 185 whp all motor Miata are still using factory coils and OEM NGK wires with no issues blowing out the spark. Rotaries have a little more demand for spark, but there is no magic coil out there. The only concern with using stock coils is the short lifespan, however that is supposed to be resolved now with the revision 'C' coils that are available.
Hi mate.nice video.may I ask please?did you had engine light on when you install the coils?
Thanks
Thanks bud. No check engine light from the coils.
Thanks a lot.))
BHR is the way mate. Everyone has already upgraded
I recently bought an 05 rx8 and it has this coil system on it. How long should it last on average?
I don't know what the life expectancy is, other than it should be much longer than the OEM units. I only have about 6k miles on these coils now, but so far no issues.
I’ve been trying to contact Bennett built performance for the past couple of weeks and I haven’t gotten a response from them. I purchased an engine from them a month ago and I’ve tried to contact them through Facebook and also email. Can someone tell me how can I get in contact with them because that’s a lot of money I’ve just spent and I don’t have money to waste especially when it’s in the thousand range
Update?
So why not the BHR system? The coil pack is inline instead of stacked.
The BHR system is almost double the cost. The GM coils and adapter pigtails are relatively cheap parts if you were to build your own ignition kit. I've gone down the rabbit hole with obsessing over ignition in the past and it doesn't lead anywhere meaningful. At the end of the day, as long as your system can create the spark needed and it is not blowing out, then there is no difference or performance benefit.
Hows that napa battery working? Is there anything special about it? Or you using it just because?... Also thanks for knowledge on the ignition coil replacement
The battery came with the car when I bought it. It leaked all over the support brace and ate the paint off of the metal, so I definitely wouldn't recommend it lol. I am probably going to move to a Shorai unit.
Garage Quinn Motors ahh okay. That sucks lol. Good to know though, i won't be going to nappa anytime soon :p
lol
Had Bennettbuilt coil kit - wiring and coils shat themselves in less than a year. Company does not stand by warranty or pay for returns.
I am sorry to hear that. So far mine have held up without any issues.
I wonder, why BB over BHR coil setup? :)
BHR didn't answer me when I inquired, BB did. I'm sure they all perform about the same though.
@@TheSlipAngle Ok. But I assume you had to adjust timing for new coils? I'm getting close to replacement in my S2 and still struggle between OEM mazda and some aftermarket ones.
@@does_not_matter_91 we picked up a couple HP increasing the dwell times but the car has a sputter in high gear 4k+ light throttle cruise so they need to be turned down a little
Do you think an MSD Ls 2 step can work with this upgrade ?
I am not sure. I think if you have an ECU that supports 2-step that you can tune, that would be the route to go if you want that as the LSD for LS might be assuming an LS firing order which is definitely not the same as rotary :)
The Slip Angle thanks for your advice hope there will be more RX-8 videos coming soon
Anytime!
I will be receiving my bennett built in a couple days, great vid, btw. Question, the original connectors to the coils, are they color coded from the factory? So you know what oem wire goes to what coil?
They are not color coded, but they are in order from left to right so you can keep track of which is what that way.
Preston Brown How did you like the coil upgrade? im contemplating on purchasing them since they're on sale right now. Thx
Well they came as advertised, no need for color coding. Just pay attention. They work great. I do have starting issues but i think its my injectors. Good luck. They worked great.
Preston Brown Thanks for replying man! Im currently on the revision c coils. Installed them @ around 35k miles, going into 88k right now. They've been great but i think im pushing it lol so its time to upgrade and be done with them. Thank you sir!
Not a problem. Keep in mind they took about a week and a half to get to me here in california. But he delivers. Also change plugs when you do the change. Good luck and let me know how it goes
Something revolutionary for the Rx8 in terms of coils: www.rx8ownersclub.co.uk/forum/viewtopic.php?f=205&t=76923
Whaf if my rx8 isnt getting any crank or start what will be fhe problem to that?
If it is not cranking at all, I would start with the battery, starter and ignition solenoid. Then proceed troubleshooting from there.
Garage Quinn Motors I've checked battery, starter, ignitions, coils, alternator. All I have left is the starter
Try tapping it with a hammer while someone tries starting it if you can. Alternately, I think most local auto part places will test your starter for free if you bring it to them, but I did once have a starter that passed the bench test and still wouldn't crank the engine. You can always just pick one up local and return it if doesn't resolve the problem.
Benjamin Sanchez might need a new starter.
I changed the starter today and it won't crank nor start. The only thing in mind now will be the grounding of the car. I do get a car with the key inside on the dashboard?
Hade you noticed any power difference? Or any difference at all except the more smoothness?:)
Yes, mostly in the 6-9k RPM range. I wouldn't say it is more smooth, but you can definitely feel it gained a slight bump in power, but this is most likely because my coils were crapping out.
Garage Quinn Motors Awesome! Just ordered from Bennett myself! Love your channel man!:) I have a question, I’m running cat less atm but I need to pass emissions test this spring, will an eBay cat work for the moment, like will it clean like the OEM?
I do not have any experience with the eBay cats unfortunately, so I
cannot say for sure. I do have a catless mid-pipe w/ built in o2 spacer
that came with the silver RX-8 I bought. I think it is eBay and I have
been running that on my car. I did throw a check engine initially, but
it eventually went away and never came back, so I thought that would
actually pass readiness.
so ive just used an ebay cat to pass the mot (im uk) and it passed emisions beautifully but i had to reset the ecu then run the car through the driving process to let the ecu learn the new setup i can find the driving process if you need
best thing you can do is install a catless midpipe so you can premix.
Stay tuned for those videos coming out very soon ;)
How come you don't see these cars on trackdays etc? Is it because of some issues regarding reliability of the engine? What are the cars weaknesses?
I don't see a lot of these cars anywhere. But if I had to guess why they aren't at track days I'd say it's because they're slow and there isn't much you can do to make them fast.
Rx8's arent the quickest cars around but they're definitely not slow( especially around corners). You don't see them around often because most people are just afraid of rotary engines and the attention they require.
I think they're pretty average handling for a 3000lb sports car. You asked about the cars weaknesses before, I'd say it's biggest weakness is the competition it has. I probably wouldn't buy one as a track day car given the plethora of other cars available.
Compared to the rx7 which was 260-270hp and 2800lbs, this car was almost like a betrayal imo. Heavier, slower, taller, and from a looks stand point, i think it lacks there also. Stripping the weight off would probably give great results but that motor needs some work or a swap if u ask me, they do still handle decently and have that rotary exhaust note tho. If you ever look up Hot Version International on youtube u will see some tuning shops run the RX8 and do well, but it's quite costly.
I would say above average handling especially for its 3000lb curb weight. Rx8's are extremely underrated cars I've seen them outrun frs/brz's in autocross events. The only reason they cant really compete with the s2000 is die to their lower power/weight ratio.
@ Elykus I agree that the rx7 is a beast but the rx8 is the topic on hand not the rx7 so i'm not sure why you brought it up.
How is your Coil pack holding up? Did you notice performance gains?
Still going!
But doesn't low compression mean new Apex seals.
Nice video but man, ditch that engine cover. Unless you drive it in the cold/winter and want to have the engine up to operating temperature faster, I've noticed my rad's fan not to spin as much as it did with that thing on even in summer with 30+ °C ambient temperatures. After long use in the summer in the past I've heard the fan to spin for a long time (the first time I got the car, it spun for like almost 10 minutes!), without it in a comparable climate, it spins for much less time than with it installed. Engine cover.. it's just a cosmetic thing.
It's been gone for a while now. Check out some of the more recent installments for this build ;)
will do ;)
Do you even drift bro?
Where can i buy tje coil
rico legaspi You can get a very similar set. But with a different bracket, in a line instead of on top of one another, from Black Halo Racing.
Not enough data? The car had been out of production for 5 years when this was posted lol
wait, rx8 doesnt have wasted spark system but the rx7 yes
Yeah the Renesis does it's own weird thing depending on where you are. This is a pretty good read: www.rx8club.com/series-i-tech-garage-22/weird-renesis-ignition-tech-info-17108/
Hope you don't unwrap Xmas presents as slowly!? 😂😃
These coils turned out bad, they didn't even change them. I will never ask them again
we back boiz pin me senpai
Under the car without stands? Not worth the risk. Use stands be safe.
You can literally see the jack stand I used next to the jack but thanks.
Go to Spec Savers
STILL DO NOT KNOW WHAT COILS YOU REPLACING WITH, FEEL I HAVE SEEN NOTHING WORTH ON THIS VIDEO
Corrie Jacobs what are you talking about? He’s linked the kit in the description. They are ls2 coils with an adapter for the stock harnesses and leads.
