fc3s + Renesis = :)

[Whizbang]

well all the turbo motors arent getting newer. The renesis is still a produced engine so i wont be surprise to see it become more popular with time. Especially in the lighter first gen.

[sen2two]

for me, the Renesis is the best rotary engine to date. Mazda didnt spend all these years and millions developing it to be worse than the previous rotary.

the 6-port Reni makes 236 flywheel. and the 4-port makes 198 i think. this means. in a completely stock N/A form. it makes either more or equal to a TII, with no lag! not to mention better milage, NA is USUALLY more reliable than turbo, no boost spikes, cooler oil, ect. ect.

give it time and when the real pros get to experimenting with the Renesis. everyone will see the true potential of the 13b-MSP.

after a while of having TII 400+ WHP daily drivers. you notice that theres really no such thing. you can call it that. but its really not.

Perhaps.....keep it up and keep us updated. You're right tho, at 400hp I couldn't call them DDs.

[drewski86]

What's the reason for not using the Renesis front cover?

[WE3RX7]

I agree on the MSP being the best production NA engine ever built for street use, but lets not get ahead of ourselves and call it the best rotary

That would go to the 26B

The 26B would be the best N/A rotary, but not the best production N/A for street use.

26B Turbo....:drool:

[sen2two]

the reason im not using the renesis front cover is for ignition. im using the FC CAS. makes it easier. and the reni front cover is hidious. but you can use anyone you like from all 13b's or 12a's. they all fit.

the reni is longer than older 13b's because the front and rear plates are thicker. they did this to make the turn in the port less abrupt for better flow. this making your only choice for oil pan a custom one. not as easy as swapping a GSLSE on there.

i dont count the 26b. it was a race only engine.

now the problem with turbo'ing the reni is the weak apex seals and the high compression. there are shops out there now who machine down the rotors to your desired compression and to fit standard type apex seals. if i had the money to go that far, i would. and i plan to in the future. just not at the moment. they already have the reni making some nice numbers in unported stock form. like i said in an earlier post. wait until the real pros get into the renesis. people will be amazed and records will be broken...

I highly doubt that.

im sure thats what other auto makers thought in 92. right before the 787 destroyed them and outlawed the motor...

not arguing. just stating an opinion.

[RETed]

787?
Are you talking about the LeMans winning vehicle?
What does that have to do with the RX-8 MSP engine?
IIRC, the 787 used a 4-rotor, PP engine.

So, I really don't understand your point.
If you think your MSP engine will outdo anything PP (even the older 13B PP exhaust), then I think you're smoking crack.
Please do your research first - SAE is a good start.
http://www.sae.org/
The advantages of the PP port over a side port is thoroughly documented.

The only benefit the MSP has over a PP is the minimizing of the (port timing) overlap.
Less overlap means for better emissions.

Don't let the 200+ quoted hp ratings fool you.
It's more due to the higher redline.

Keep in mind, at BP motor with the "older" PP exhaust will produce the same if not better numbers than the MSP.

Not ALL front covers are simply interchangable. ALL will bolt to the front iron yes, but not all have the same pattern on the oil pan bolts. REW front cover is different from earlier ones. I've yet to inspect a renesis front cover up clsoe for a swap, but from the picture, it looks as if its the same as the REW (oil pan bolt pattern wise) in which case if you pan to use the RENESIS oil pan, you'll have to modify one or the other.

wrong

the renesis has higher torque and power across the whole rev range than any previous NA rotary

it probably has better low end up to about 4 or 5000rpm than pp motors too.

your right, you completely misunderstood what i said. the 787 4-rotor was the only rotary engine in that class. and im sure all the other automakers didnt think it stood a chance until is destroyed all the other competitors. so calm down buddy...me no likey crack

and the redlibe has nothing to do with the power output directly. they red line is just where it makes consistent power to. you could rev all day to 15k, but if your not making power there, whats the point?

and yes, a BP or PP will put out higher numbers. but no exstensive porting has been put into the renesis yet. again, give it time. also, how reliable and how streetable is a large BP or PP? or even a small semi-PP? these motors are making in stock form almost what those make. this is my point. stop being negative. no ones trying to argue here.

and i have put a 12a, 13b/gslse, TII,13b NA, and FD front cover on the renesis. all work just fine. only one hole dosnt line up. wich is an easy fix. try it out and you'll see what i mean.

and i already stated that a custom oil pan will be needed given the renesis is longer. read the statement right below what you quoted.

jeeze... maybe i shoud not of posted this here. just trying to put it out there. cause theres so many people asking about this. but no ones done it... why do all the internet guru's nit pick. isnt this why people hate rx7club? and come to places like this
