THANK YOU 👏👏 For building and documenting what no one else was able or willing to do. You are a gentleman and a scholar! You are WAY too classy for a ratchet hood dump, build a proper exhaust, it'll be a walk in the park after building that hybrid n/a header 🤣
the renesis has taken me almost 100k miles with no issue, i saved money by using 87 octane watching your videos, keeping her decarbed with no premix, and i spray water in my brake booster to decarb her, the rx8 has surprised me, im not a rich man but i do love the rx8, and i love her i daily her, she taken me places, i wanna keep her alive, your advice means a lot to us, i was gonna sell my rx8 until i saw your videos, it made me understand my car a lot more thank you, i wanna keep her alive till im old and my nutsack dont produce nut anymore, pass her down to my great grandkids, | yo is that grandpas whip, its so old its 2004 it dont even have auto pilot then i walk in all wrinkly and shit, ahhhh you kids dont understand the sound of the reeeeee pop pop with your electirc mobiles all i say is man thank you! next time you rebuild an engine mind recording it, i wanna rebuild mine
@@vickanis2234 rx8 premix video, saw him put 87 on the gas tank, and the 8 is not tuned for premium, source, i been driving almost 100k miles on regular gas, i beat the shit outta my 8
because his poorly built engines all have crap compression, you don’t need octane with low compression. And 100k miles isn’t really special for a Renesis. Sure some have gotten less, there are those who got 150k - 200k miles. Though not as many on the high side as the low side. .
Refreshing to see someone try something and be honest about the results even if it didn’t work out. Seems most everything on YT is endless hype or doom and gloom clickbait.
read if you want not necessary when i bought my rx8 i didnt even know how to drive a manual, i didnt even view the car, im not rich i had to plan 130,000 trees to make money for it, and it hurt, 2,000 trees a day, back breaking i just wanted the car, i told the seller than he was like wtf, dont worry bro i'll teach you (he didnt) i spent an hour drifitng the car in the parking lot doing donuts in the winter to learn then some told me to try the roads, i was so scared of owning this car, reliability and all, warm up, 97 octane, i was scared and going broke but i loved the car, i was gonna sell her because i was so scared, and couldnt afford it anymore then i saw your videos, i was like what, then i poured water in the gas tank, mechanics wanted 600 bucks off me to fix it, so i used my brain and science and youtube, i managed to fix her, it gave birth to my love of wrenching on the rx8, i fix my own stuff now, im just really stoned and felt i should share, the rx8 is a special car to a lot of us kids who got older, its a car that looks dope and dont cost an arm and a leg, its a car that will give a man a smile, a little light in a cloudy world at times, the 8 has changed my life for the good, i can fix my buddies car now, the car brings smiles to strangers i keep getting compliments on 8 and when i got pulled over for running a border check point, i was talking to the cops about the car not the incident, i was under arrest anyways for missing the border check in thing, in a world where everything is the same, the 8 chooses to stand out from then norm, its less than 5 grand at most places and would treat the owner really well with a little bitch fit here and there the 8 is special, keep on keeping on Mr Rad
I feel like you need to talk to the rotary doctor guy in nixa Missouri. The way he explained the RX-8 and it's computer essentially having to constantly try to get back to stock no matter how you try to trick it it's one of the first learning computers that Mazda actually produced. You can thank the EPA for that! I talked to him extensively when my dad was thinking about getting an RX-8 after fully rebuilding an FC RX7 GTIU street port(with header and fully functional 6 ports off of the smog pump vacuum😊and an 85 12a with all Atkins!
Do you have any video recommendations for a Rx8 Renesis talking about temperatures? I usually take it to very high temperatures. Due to the climate in Spain I usually reach temperatures of 220ºF 104ºC and then I start to cool it down by driving very gently, but it is frustrating to have a sports car and not be able to drive it hard. (I have silicone hoses, a mishimoto radiator and a decat exhaust with catback, I don't know what else I can do to keep it from getting so hot.
I have some old videos with my green rx8. 220 is pretty warm. I've rebuilt the ducting in the front end. And moved the battery to the trunk. Also added a cold air intake to remove the airbox. That let's the radiator breathe a lot better
I did the second option, bought a reman from Mazda , sohn adapter, deleted cat/hks hi power , Bennett built LS coils, made my own intake and use versatune. It’s a completely different car than stock, I don’t need a dyno when she sounds better and shoots flames at 9k she’s running great
i feel like the hybrid porting starts making a bigger difference if you're working with forced aspiration where you're pushing denser air through. you gotta work with a proper engine though, your compression ratios on that are pretty low. The hybrid setup can make a difference, but the airflow needs to get staged to the RPM. it would be cool to have some kind of valving on the exhaust just like the intake is done. the ports open to allow more air through as the engine starts pushing more through.
no it doesn’t, even the Mazdatrix turbo hybrid from 16 years ago wasn’t that special there have been several 420 - 450 whp non-hybrid Renesis setups on RX8Club. The problem is that most people do it wrong, like believing this hybrid nonsense, or too cheaply. They don’t even understand that the hybrid engine Kyle Mohan built costs close to $10,000 USD. And is still not going to be anywhere near what an RX7 REW etc. turbo engine can do. Even with a turbo it has no power below 5000 rpm. It’s a crap setup that people who don’t really understand rotary engines are greatly mistaken about. Because they don’t fully understand the details about what makes a Renesis different than the prior 13B engines. And why it doesn’t then respond the same to the prior 13B engine modifications.
@@nobodyspecial5026 it ends up being a crap setup because larger ports nerf your low end torque. The rotary engines with the smallest ports developed their peak torque sooner. The 4 port renesis has smaller primary ports than the 6 port and it had slightly better low end torque. The large ports are only beneficial at high rpms when there's less time to get the air and fuel into the chamber. A "hybrid" build would essentially have to be totally custom designed in order to actually make a difference and likely you wouldn't see a real benefit without building it to be able to run at higher rpms than 9k
Somebody needs to do some Computational fluid dynamics (CFD) on this engine, before drawing a conclusion. The overlap between intake and exhaust still doesn't explain the drop of power/ torque at high rpm. A 13B PP NA will see an increase of power/ torque as RPM rise, so something is restricting the flow (on either intake or exhaust) in this hybrid engine.
Oh you had to tell me bout the K swap. Now why did you go & do that. I'm Captain cheep and what's not to like. !!!! . then the guy says the hp and they race fds . I can't turn on ( beloved rx7 s ), but those guys seem to get it and cheep. Yet I drove a gold wing 100,000 miles ( Honda fan ). He said $50,000 \ like $70,000 ,than he blows that up. You kids ( stay off my grass, ) where do get this kind of money? Love what you're doing . rx8 ,miata hybreeds turbo ( ouch captain cheep), , 81, and 90 rx7 owner , not a poser ...
Hybrid is a waste of time, this is all due to all the hype and misinformation from the drift guy . All motor na is a dog. And turbo is still a dog. It makes about the same peak power as a 13B + -. I know because I been down this road. Kids don't buy into the hybrid hype.
I like rotaries, but they have limitations. I also knew the renesis was an eventual time bomb. I’m Going with the blasphemy route, it’s not cheap but cammed LS3 is hard to beat for power and reliability.
one more thing mr rad, you are fucking rad, my grandkids gon stumble upon this video around circa 2070 dying on my deathbed they gon be like grandpa, yo car kinda slow, imma engine swap it, imma summon up all my energy to bitch slap the child but i stop and remember your channel so i say just turbo it look rad potential thank you mr rad i appreciate all your efforts, thank you
I will state my reasons for the Hybrid again. Yes, the results you got were poor. But what i wanted from the hybrid renesis is more reliability, seeing more exhaust flow would've make sense. But reality has a different say to it.
How about..... instead of a conventional turbo, or supercharger, you try putting in an electric supercharger instead? It's all about trying after all, and it's something that hasn't been tried in a rotary yet as far as I know.
I just had a thought. Given that the hybrid's exhaust seemed to flow too well, would a wastegate style opening for the peripheral ports have improved the bottom end power? IE: The PPorts open when the 6Ports do, or something like that. I know that ship has sailed already, but was curious to hear your thoughts.
thank you mr rad, i do look up to you for rx8 advice and learning, nobody really wants to do stuff to the renesis, the renesis is the most misunderstood engine to the point where people will just say ehh just ditch it, nobody cares about the renesis
What if you put electric controlled exhaust cutouts on the renesis exhaust ports? Have them closed for low rpms and open for high rpms. Maybe to balance the air flow throughout the rev rang
Definitely a shame on the hybrid. At least it was worth a shot though. I'm interested to see how the turbo route ends up for sure. If it can be somewhat easily tunable, cost-effective, and not have over-heating issues (this is the biggest thing I worry about ESPECIALLY the oil) then it could end up being a great route. Being able to track it turbo'd as well would be a fantastic test. I agree with another one of the comments though that I would definitely like to see the stock exhaust option if possible. Having a hood exit for a car that makes slightly over 200hp would be a bit too extra in my opinion lol.
i did a couple of years ago rebuild renesis racing beat port templates highmount turbo precision 6262 big intercooler all tuned with versatuner 365hp/294tq @14psi and it drove like a dream ...a little difficult to tune mass airflo tables but we did it !!
the guy from the RX8 forum who always attacks the hybrids, is very happy with your videos... for my part i am still waiting for updates with Turbo to see if it is worth a renesis hybrid with the exhaust side ports sealed completely , while using Apex from RX7,since this mix would be a great alternative to the REW (i have a 2010 S2, that swap is quite difficult because of the lack of support for the SII ).
no he’s not and not really sure why you’d post that he even posted the links to these videos and stated that he’d be pleased to be proven wrong because it would teach him something new. The issue isn’t him, it’s people like yourself who can’t even be honest enough to post the truth, let alone accept it. he went into great detail technically on why a hybrid won’t ever work well. I bet you don’t even understand his explanations, but even Rad was honest enough to admit in a prior video that he didn’t really understand. but talk is cheap, throw your own many thousands of dollars at it and then maybe you’ll have something honest to post up. .
I dont get it, why not just boost the hybrid? The problem with the renesis is the weak housings, a problem that the hybrid wont have so why give up now and not boost the hybrid? I think is not the right move, hybrid might also shine with boost.
@@henrylima6974 studding can help a bit, the crack is not really a problem except that oil is going through than canal where it cracks, so with an external oil line mod it doesn't matter if it cracks or not
@@koekcoek ok but why cant renesis engines handle 600whp? Is the housings right. If so why not try to push the hybrid motor to see if it handle way more boost then a renesis.
Hey quick question, I would like to build a VW Polo with a rotary engine, I would ideally take a 12a with a carburetor because it would make this conversion easier, but getting a 12a is quite difficult (in Germany), can I get a more modern 13b convert to carburetor?
tal cual, es triste andar lidiando con traductor para cualquier cosa del RX8 , tengo un S2 que ya empezo a mostrar fallos de compresion , por lo cual ando mirando como construirlo a futuro jaajj
Have you given any thought to a rear mount turbo setup? You could keep the rad headers and not cramp up the engine bay, but would take some serious plumbing
Erich: "I wouldn't recommend this build" Me: *with $7k into a hybrid build* 😬 nah it'll be exciting to the loss/gain with RX7 seals and no porting. If things go smooth next season I'll do more proper header focused on the Pports and hand this one off to anyone else brave enough to try a hybrid build.
Honestly I appreciate your effort to do this build, I was all game to do a hybrid n/a build, but waited to see how yours went, think I'll just save for a 3 rotor or rew turbo build now, cheers my guy, you did well 🤌
@liamflynn6929 I agree, iv been a pretty die hard screaming N/a rotary fan, but I don't have 3 rotor money, so for now I'll compromise and go for a Rew. Also can I get a hell yeah! For those of us that fell in love with a 10k redline without spending v10 money, perfect entry level engine for the race car enthusiast's, rotaries are just so nifty!
It seems like this engine layout was made up with somebody eating some fungus or some Sid in kiwi land! That or some piston people playing a trick! There's basically nothing online about this hybrid except for you and a couple other kiwis and Australians.
You are kinda local to me or were, we met at a cars and coffee last year at the blues picking parlor event. Keep up the good work! I also reached out on ig a week or so ago after I put 2 and 2 together after i found your card in my wallet
I’m begging for a turbo hybrid build in an RX-8. The RX-7 seals with the ported housings and a turbo is my build of choice but I gotta see it in action before I can commit to building it myself. Thank you for everything you’ve done so far but please don’t give up on the Hybrid dream!
Just finished watching the entire series and im thinking of picking back up my 13b supercharged build because of this! Always love the content keep up the great work!
Exhaust close on the peri exhaust is so late that even the aux ports are open before it closes, and there's almost no potential for exhaust tuning. It having been dummy fat supports that as being the "problem". Supercharging it, a la 2-stroke diesel, might be the only way to make it remotely useful.
Forgive me Im kinda a newb so I could be wrong, but what's the point of a turboing the hybrid if its not that great NA? The 13b-REW gets great power turbo'd I imagine it will be alot less due to its high compression ratio right? I was most excited for the hybrid to see the kind of NA power you can get from it since I was told the exhaust port was the biggest restrictor of power. That jazz aside I THOROUGHLY believe the Renesis is a highly underrated engine, might not be the best rotary engine overall, its the best NA rotary made
dude you're damned if you do, damned if you don't. say do the hybrid, you'll get everyone on your ass saying it's a bad idea. say don't do it, you get everyone else on your ass saying it's a good idea
Basically the factory knows best for NA. Turbo hybrid has already been done. We know it works for turbo See Carl s videos. BUT is FD turbo engine cheaper and easier
it doesn’t need an adapter plate, it just needs to be modified/machined for the REW front counterweight to clear the Renesis cover. I have one installed on an REW engine
i support the boosted version. thats all i wanna try hybrid for. seems more affordable than REW. plus versa tuner seem more feasable then haltech with a boomslang this is my first rotory and theres not alot of rotory peeps in ky.
no it’s not, the hybrid engine Kyle Mohan built 2 years ago and is still sitting there is $10,000. Just the hybrid engine, not including everything else needed to install it, all the turbo and turbo support parts, etc. I’m not trying to bash on you guys, you just don’t really understand the realities of this being such a bad idea.
More reason why this needs to happen. Video proof. Everyone is always saying it's a bad idea but that usually all the explanation you get. Ive never heard mohans cost divulge. I Imagine it's possible to spend 10k on the motor itself but I've priced a near finished build for less already. Thats doing the work myself minus tuning. Either way I've been back and forth hybrid and the REW swap for over a year now. Hybrid is cheaper everytime. Lost of people get started with this project and never commit. He already has it built just add the turbo and let's see
did US only get 141kw models? 170kw models aren't that much more expensive and a brand new rebuilt, complete package engines, can be bought for 3-4k euros
I think it's dumb how you're not boosting it right away, I get that you have to maybe add some studs around the spark plug area, and get the rotors machined for deeper seals, but to sideline it for a stock renesis is just meh.
With new houses, its easy around or above it. A housing cost 1000 minimum. A housing for an rx8 can handle between 100-200k km depending on how it did run in its lifetime
im over 6k and re using my rotors and side housings. All the factory seals and o-rings, control rings, bearings are very very expensive. you can build cheaper with crap aftermarket parts- good luck

You are WAY too classy for a ratchet hood dump, build a proper exhaust, it'll be a walk in the park after building that hybrid n/a header 🤣

I wish the greddy turbo kit was still around, it had such a great compact fit and good for that 2-250hp range with fast response.
Most of the kits aren't available in a reliable way, but you can get a manifold and build your setup... look up Brettspeed.
turbo greddy + MazdaEdit kit, today would be a great option for the renesis, too bad everything related to renesis performance is not available.

but talk is cheap, throw your own many thousands of dollars at it and then maybe you’ll have something honest to post up.

I dont get it, why not just boost the hybrid?
The problem with the renesis is the weak housings, a problem that the hybrid wont have so why give up now and not boost the hybrid?
I think is not the right move, hybrid might also shine with boost.
@@henrylima6974 most of the time the renesis crack under to much boost on the plates not the housing.
@@koekcoek so what if it gets studded? Im sure the problem is in the weak housings correct?
@@henrylima6974 studding can help a bit, the crack is not really a problem except that oil is going through than canal where it cracks, so with an external oil line mod it doesn't matter if it cracks or not
@@koekcoek ok but why cant renesis engines handle 600whp? Is the housings right.
If so why not try to push the hybrid motor to see if it handle way more boost then a renesis.
@@henrylima6974 They can handle 600hp but its at the cost of reliability.
Good to see some honesty around these BS hybrids!
Hey quick question, I would like to build a VW Polo with a rotary engine, I would ideally take a 12a with a carburetor because it would make this conversion easier, but getting a 12a is quite difficult (in Germany), can I get a more modern 13b convert to carburetor?
If you can find a carb manifold for a newer engine, you should be able to make it work.
I wish your videos were in Spanish, luckily thanks to the quality of the audio, good subtitles are generated in Spanish with a 70% accuracy rate.
tal cual, es triste andar lidiando con traductor para cualquier cosa del RX8 , tengo un S2 que ya empezo a mostrar fallos de compresion , por lo cual ando mirando como construirlo a futuro jaajj
This is incredibly disappointing
Have you given any thought to a rear mount turbo setup? You could keep the rad headers and not cramp up the engine bay, but would take some serious plumbing
Yes, but when yall see where the Hybrid is going you'll will be happy
Erich: "I wouldn't recommend this build"
Me: *with $7k into a hybrid build* 😬
nah it'll be exciting to the loss/gain with RX7 seals and no porting.
If things go smooth next season I'll do more proper header focused on the Pports and hand this one off to anyone else brave enough to try a hybrid build.
Ill be watching to see how it goes!
@@Darkipod appreciate it! Wrapping up a budget track car series then hitting the rx8. Hoping to have it start in 3 weeks
Honestly I appreciate your effort to do this build, I was all game to do a hybrid n/a build, but waited to see how yours went, think I'll just save for a 3 rotor or rew turbo build now, cheers my guy, you did well 🤌
I think the REW swap is probably the best bang-for-the-buck
@liamflynn6929 I agree, iv been a pretty die hard screaming N/a rotary fan, but I don't have 3 rotor money, so for now I'll compromise and go for a Rew.
Also can I get a hell yeah! For those of us that fell in love with a 10k redline without spending v10 money, perfect entry level engine for the race car enthusiast's, rotaries are just so nifty!
It seems like this engine layout was made up with somebody eating some fungus or some Sid in kiwi land! That or some piston people playing a trick!
There's basically nothing online about this hybrid except for you and a couple other kiwis and Australians.
You are kinda local to me or were, we met at a cars and coffee last year at the blues picking parlor event. Keep up the good work! I also reached out on ig a week or so ago after I put 2 and 2 together after i found your card in my wallet
I’m begging for a turbo hybrid build in an RX-8. The RX-7 seals with the ported housings and a turbo is my build of choice but I gotta see it in action before I can commit to building it myself. Thank you for everything you’ve done so far but please don’t give up on the Hybrid dream!
Just finished watching the entire series and im thinking of picking back up my 13b supercharged build because of this! Always love the content keep up the great work!
Love the experimentation. Thanks so much for doing this.
But where is that link?
Exhaust close on the peri exhaust is so late that even the aux ports are open before it closes, and there's almost no potential for exhaust tuning. It having been dummy fat supports that as being the "problem". Supercharging it, a la 2-stroke diesel, might be the only way to make it remotely useful.
K is the way..
RX8 was NEVER a drag car. It's a road course type car and far exceeds the cars you mentioned.
The camaro kills it around a track...
proof lol?
@Vipurs Nurburgring times
Rx8, 8:42
Camaro SS, 8:20
Camaro ZL1, 7:16
Obviously depends on the course! But this track is the "Standard" testing ground.
Forgive me Im kinda a newb so I could be wrong, but what's the point of a turboing the hybrid if its not that great NA? The 13b-REW gets great power turbo'd I imagine it will be alot less due to its high compression ratio right? I was most excited for the hybrid to see the kind of NA power you can get from it since I was told the exhaust port was the biggest restrictor of power.
That jazz aside I THOROUGHLY believe the Renesis is a highly underrated engine, might not be the best rotary engine overall, its the best NA rotary made
finally, somebody who uses their brain.
Incredibly excited for the turbo renesis content! Let’s gooooo!
Can you make another motor mount
And this is why there is no one posting vidoes of a hybrid motor running, because they are all crap
Kyle Mohan doesn't approve
still waiting over 1.5 years for it to run NA, may you meant he doesn't prove …?
@@nobodyspecial5026 I meant the turbo, he ran it for some time already, and it works
Could you please boost the hybrid motor?
dude you're damned if you do, damned if you don't. say do the hybrid, you'll get everyone on your ass saying it's a bad idea. say don't do it, you get everyone else on your ass saying it's a good idea
Pah, go 20B with a street port and a turbo.
A 20b is $15k-20k for a stock engine lmao
if stock renesis turbo works well will be sick
You ever thought about building a rotary for the sole purpose of longevity and reliability? How would you do it?
4 port 13b with gslse rotors. Big street port. Weber carb. Done
Basically the factory knows best for NA.
Turbo hybrid has already been done.
We know it works for turbo See Carl s videos.
BUT is FD turbo engine cheaper and easier
Don't know if u know of Kyle Mohan (fd driver) but he has several vids on the hybrid and how to make it work and make power na and turbo
no, he has no NA results and the turbo results from 15 years ago are not that great.
Why I have a lot more than 200hp with my hybrid and you can. Oh and the compression on the engine is 110 not 90
Explain how you’re getting so much power out of you naturally aspirated hybrid engine then
How about try the adapter plate. Rx8 front cover to a rew motor.
it doesn’t need an adapter plate, it just needs to be modified/machined for the REW front counterweight to clear the Renesis cover. I have one installed on an REW engine
i support the boosted version. thats all i wanna try hybrid for. seems more affordable than REW. plus versa tuner seem more feasable then haltech with a boomslang this is my first rotory and theres not alot of rotory peeps in ky.
no it’s not, the hybrid engine Kyle Mohan built 2 years ago and is still sitting there is $10,000. Just the hybrid engine, not including everything else needed to install it, all the turbo and turbo support parts, etc.
I’m not trying to bash on you guys, you just don’t really understand the realities of this being such a bad idea.
edit, it was built Dec 2022 so it’s a little over 1.5 years just to correct myself.
More reason why this needs to happen. Video proof. Everyone is always saying it's a bad idea but that usually all the explanation you get.
Ive never heard mohans cost divulge. I Imagine it's possible to spend 10k on the motor itself but I've priced a near finished build for less already. Thats doing the work myself minus tuning. Either way I've been back and forth hybrid and the REW swap for over a year now. Hybrid is cheaper everytime. Lost of people get started with this project and never commit. He already has it built just add the turbo and let's see
did US only get 141kw models? 170kw models aren't that much more expensive and a brand new rebuilt, complete package engines, can be bought for 3-4k euros
We got 232hp for all the manuals, not sure what the kW rating is
@@liamflynn6929 right, 141kw is 192hp and 170kw is 232hp
@@MastigosWilkins yeah, we got 232 for the manuals and I think the autos were only like 175 or so
I think it's dumb how you're not boosting it right away, I get that you have to maybe add some studs around the spark plug area, and get the rotors machined for deeper seals, but to sideline it for a stock renesis is just meh.
There is no way prices are so different. 5k for a rebuilt?
With new houses, its easy around or above it. A housing cost 1000 minimum. A housing for an rx8 can handle between 100-200k km depending on how it did run in its lifetime
in australia its over 5k for rebuild 12a/13b no porting usually,
Lol, housings get lapped and nicasil plated, you kiddies don't know shit.
I feel as if the next project and no I'm not a pateron but the chasis it's telling me. I personally would go for a nd.
im over 6k and re using my rotors and side housings. All the factory seals and o-rings, control rings, bearings are very very expensive. you can build cheaper with crap aftermarket parts- good luck
one more thing - is that lift all the way up, and you're still hunched over?
