I can't emphasize enough how amazing it is to have this kind of information available publicly. Thank you!
I greatly appreciate the support, hopefully this will turn into a full car build.
@@KyleMohanRacing Could you run this same engine with hydrogen fuel ?
It’s nice to see some legitimate reviews on this type of setup for a change. These hybrid motors have built up a reputation for being very unreliable for unknown reasons because no one that has done these setups has come forward with any real world data or updates of success, failure and/or problem areas. I think much of your success with this motor has a lot to do with using a proper setup whereas others are trying to cut corners everywhere they can which tends to lead to issues more often than not. I would like to see some long term data from a daily driven application as some places don’t require smog at all and can be done in those areas, but I don’t doubt that it can be and is a reliable race only motor. I look forward to your future updates and reviews on this
They are great 👍 a lot of problems sorted
@Nate Rist let’s build one for my car
Would love to see this and the flange in actual use- especially using a semi PP config with ITB's and sequential opening on the different ports- would give us something reminiscent of VVT and VVL if done correctly
That's a lot of work.... I hope someone tries it. Id like to see it as well. For now I like the simplicity of the street port hybrid and turbo. Effective hp out of a renesis based block.
Yeah maybe some oem motorcycle intakes do something like that
Thanks for the vid Kyle. If you are doing another full build please show us! The RX8 community really needs to be thrown a bone. The cars are great but the renesis needs more reliability and power potential.
This'll be my next project on hobby drift RX8.
Always wanted to do the hybrid renny. I've rebuilt a stock renesis and that was fun. But I'd like to be able to rip in 3rd gear and I'd be caught dead before putting an LS in it.
I've already got 2 renesis engines so I'm hoping it'll work out cheaper than buying an REW.
20 years ago, i had mazdatrix rebuild my 12a and street port it. You all did great!
I was just reading a book about Mazda’s rotary engines and got the idea to do this when I saw the difference between renesis and pre renesis engines.
Awesome to see that it have been done and that it works nice! Thanks for posting this on youtube!
Yes 👍
Great info! Also, happy to see that 1st gen back in the family!
👍
I want to see the whole exhaust manifold!
Go watch the other videos
We need these motor built by the quantity if proven really reliable, of course with regular maintenance etc. I'm willing to invest in one of this, I'm pretty sure there is alot more people willing to do so. #rotary
No issues with them. Just a good way to hotrod a renesis block.
@@KyleMohanRacing from your experience with it, do you think a hybrid renesis could be used for a daily/track car?
Have you ever builded an NA aplication and did it have any power gains or just improved reliability?
Thanks in advance!
I have not. But a friend over seas did and his experience was very good. We have one customer building a NA setup. And we hope to debut our own as well. Just takes time.
@@KyleMohanRacing Thanks Kyle! Looking forward for the movie.
Cheers,
Florin
I really want to do one of these builds with my CNC ported irons and supercharged 👍🏼
You should do a Rx8 project car Hybrid build for the channel
is it possible to fit 9.7 cr rotors from a '90 rx7? so you dont have to machine the rx8 rotors to put the taller apex seals?
Would the stock Series 1 Rx8 OMP and its respective oil lines and injectors work with the GSL-SE rotor housings? How many oil injection ports do these 1985 housings have?
just block off the oil injectors, do a OMP delete and premix
You mentioned that the intake manifold doesn’t exist for this setup. Why can’t a stock Rx8 intake manifold work? It looks exactly the same in terms of intake. I want to do this build NA and using back my stock Rx8 components
Thank you for this video 🙏🏼
I believe Ryan rotary performance here in the uk are currently working on a semi p intake port & intake manifold for the renesis where the intake runners for the pp will include a valve opened using one of the original intake valve circuits or the solenoids themselves (think it may have been the ssv). This might solve the low down power issue with a semi p in the renesis. Interested to hear your thoughts
I’m building one now I have housings irons e shaft now to get my rotors machined I wish I had more money to get it studded but I don’t but I’m getting it clearanced and balanced so I’ll probably stud it later if it lasts
It’s really weird I always saw this as being a possibility but didn’t think much about this after I sold my engine.
I have to ask, from an objective standpoint, which engine is better? This MSP-GSLSE hybrid, or the REW? I would think that the turbo is going to spool slower thanks to the lower exhaust gas velocity, but it gains in top end exhaust flow as a result. I'm more curious about the intake though, does the extra intake area contribute to anything in this hybrid engine, or is it not worth compared to an REW?
Can you do a video goinf over the difference between RX8 & RX7 rotors? Especially in relation to how it would effect this setup?
If you used stock RX8 Rotors would you see reliability issues only at high RPM or just all around performance?
Have you gone into how you would upgrade the fuel system for a 13B-MEP?
How much HP to expect with it ran in NA?
I've always wanted to build one. The older I get the more likely it becomes.
280whp if what I've read is correct. Sounds very well suited to an NA build in a lightweight vehicle, but even better with a turbo.
@@th3ch33t Yeah, I think 280 hp with carburetor and simple tune. I’ve seen a few people with drag builds get close to 400 hp with nitrous.
sorry if my question is silly, but could you remove the side ports and just use the peripherals ? or are the advantages of the side port really worth keeping ?
Instead of the RX8 rotors ,,,why not use the fb rotors...already used the fb housing.
Great video. I was just curious, if left NA would these housings create less torque than the stock housings?
love it!
What do you do with the engine mount bracket ? it will not sit flat ontop of the exhaust flange. Best ECU is the Adaptronic plug in I developed here in Australia .
Have to make a mount or modify oem. We have done both. Adaptronic is the easiest, but there are better ECUs available. Just not plug and play. Are you with Adaptronic?
@@KyleMohanRacing No not part of Adaptronic but have worked with them to develop the RX7 and RX8 plug-ins. I run a race shop in Australia and the RX8 Cup race series too.
@@TheRicShaw very cool. That looks like a fantastic series. Keep up the awesome work
Ric Shaw hi Ric how you going I have a rx8 now I’m very interested in flash tune or plug n play can you get back to me thanks🖐👍
Ok Kyle couple of questions for you... You said the XR8 Seals don't hold up on the port. Have you ever tried a bridged port? Like having 2 ports in the housing merging before the header. And has anyone ever tried putting expansion chambers on one of these. I'm thinking like 2 stroke exhaust where the megaphone section creates a vacuum in the cylinder and the reverse cone stops and or reverses flow back into the cylinder?
That link doesn't work ?? Do you have another listing?
Since this video was made gsl-se rotor housings appear to have been removed from existence, any advice on where I can get a set?
Hmmm... I wonder what it'd be like to do this to my daily RX-8...
So will standard ECU run this in naturally aspirated form ?
do you have a video off the exhaust manifold and intake off the the hybrid motor going and in na or turbo form cheers
Very cool 😎.
Kyle id love to have some discussion on this engine with you. i’m very interested in putting a setup like this in my 1991 toyota supra.
I want one!
so i could put a microsquirt on to control fuel and timing,but keep oem for gauges?
Hi Kyle bevomkng a fan motivated to star a rotary channel...✌Do you think there's flow or hp gains by using a renesis center plate in a turboII or cosmo engine?
Is there any video of it running? I need to hear n/a and turbo sounds.
Would this engine build be able to on on rx8 oem ecu?
Whats the price of one of those engines? And also would be compatible with automatic transmission?
Won't the oem RX8 intake system work in a NA configuration? Not asking for a friend.
Fucking awesome.
Do you sell built engines?
Is there any way to fit a rew intake on a rx8 using The 6 port adapter from racing beat
How will this car drive if you put such a motor without a turbo? in stock but with such an exhaust
Great video, just wondering what apex seals are used rx7s on rx8 rotors?
he said in the video that they machine the rx8 rotors to accept rx7 apex seals, about 4:10 timestamp
Are the 3mm seals better than the 2mm. My rotor seal grooves have some bruising from the worn seals.
2mm is better
What kind of HP numbers are you getting from a factory RX8 engine
How much would something like this cosr
Why do you do for motor mount on that side?
How much NA hp? 5hp?
What kind of exhaust you gonna use ?
You mention in the video that you would have to build the intake manifold along with the exhaust. Why wouldn't you use an RX8 intake manifold?
What kind of power would something like this be expected to make NA? Would a half bridge/ full bridge plus all this exhaust area have any advantage over just a large peripheral exhaust port?
how many psi basic can be printed?
Still not seeing it?
No, it’s not more efficient. The reason why is that as soon as the Renesis rotor moves 3* past TDC the full primary intake port begins to open while the the peripheral exhaust port that was added is still fully open. Even if the Renesis intake ports aren’t modified, adding a peripheral exhaust port creates 13B peripheral intake engine type overlap when paired with Renesis side plates. The difference between this and a 13B PP is that you simply can’t achieve any exhaust pulse tuning on a Renesis hybrid due to the exhaust signal being broken up into 3 port streams, of which two side port streams open later and close earlier. This disrupts and weakens/destroys the potential for exhaust pulse signal strength.
So it will never be strong NA and the only real hope for FI is to treat it like a PP intake engine. Which means a big turbo with an even bigger turbine housing because it’s not going to be tolerant of negative emap with all that intake/exhaust overlap that the peripheral exhaust port creates when paired with Renesis plates. It will never be as strong as an unmodified Renesis in the lower rpm range because it’s not going to have much of anything below 5000 rpm, just like a 13B engine with a big intake PP.
Even back 10+ years ago when all the hybrid Renesis began, the output was subpar compared to what an unmodified Renesis was capable of. It wasn’t as obvious then because of all the people doing it wrong and making it seem like a Renesis and turbo weren’t compatible. Now there are quite a few examples of people using sufficiently sized turbos with good tuning and support mods.
What it really comes down to is that most people still don’t grasp what it is that makes the Renesis so different than the prior 13B. For the same reason those differences are why most of the mods used on the prior engines don’t work on the Renesis.
Our turbo setup worked fantastic, that's what I built and have experience with. The setup was raced by Mazdatrix and was very successful and the shop has over 30 years of rotary experience. Dyno numbers don't lie it was a very efficient set up in our application. 👍
What are you on talking crap the. Set up works. Think again
How much for the flange?
Rather then using renesis rotors can other series rotors be used? I too would like to this hybrid with a semi-pp and working electric opening for 5/6 ports or semi-pp.
I believe that can be but you need to (maybe don't have to?) machine the bevel on the sides the same as the RX8 rotors to get the port timing right for side intakes.
I'd say the best arrangement to modify a Renesis would be Peripheral Intake Port, the NSU Ro-80 type, beeter if rectangular or square, Reed-Valve controlled, closing forever Side Intake ports, keeping the Side Exhaust ports.
For an improved Wankel RCE, avoidance of port overlap is essential.
Anyone has tested in a Mazda the Toyota concept, having a glow plug, an ignitor, in the leading plug hole?
Blessings +
Why do ppl say this is un reliable?
im still waiting for the one from 5 years ago lol
What are you waiting for?
The GSL housing exhaust ports are having so much overlap with the Renesis intake ports, that this engine will make power only at the top end. Not suitable for street use.
It does have but not a lot, way less than a BD or semi pp.
all rotaries besides the renesis have overlap
go six rotors, turbo cooling and turbocharging
Still waiting btw. Lol
Update soon
@@KyleMohanRacing thanks bro!
I want to see you eat a taco 🌮
