Wait, first you say its for SCCA, now you say its for a daily driver?



And honestly, the renesis isn't impressive enough to go through all the work to get it into an FC... its a fly by wire system, and the ECU freaks out if you so much as disconnect the climate control. I'd probably be cheaper in the long run to just buy a used RX-8.... you get 2 extra seats.



But if you want to be the first, be my guest.



I never said it was FOR scca.



when I build a car. Its an all-purpose car. grocery getter/street racer/drifter/scca/ect.

I dont really like the rx-8 as a whole. but the renesis is a definite upgrade.

If you want a renesis, buy an RX-8. The great thing about the 8 is handling. I have heard claims from FD owners who say that an 8 handles the same way.

Does anyone know what needs to be done in order for a successful swap?

All Purpose and SCCA dont mix. You will get shoved into A-Mod or worse.



Good Luck on the project, but I wouls be concerned about the ECU Issues. Another point you conviently gloss over: The quietness of the RX-8: ALOT of that is due to the unique double wall exhaust; take that away and its back to being a rotary noise

you need to make engine mounts. the high power renisis either needs the stock ecu, or a really high end aftermarket ecu to switch over the 6port stuff (its driven by stepper motors), plus its expensive. the engine is $2400, but the 6 port intake is $1200, wiring harness is $650, etc etc. at this point it would be less expensive to do a 3 rotor swap.

I think thier is 6 injectors too.



You would definately need a donor car, and most yards wont let that car go just yet. Still alot of money to be made in parts.

yea, do the swap...........and the car will still be slow.



save money and turbo it, youll be beating rx8s left and right.

porting, if you didnt know. reduces reliability and most times, needs tuning. also reduces gas milage. And in order to make enough power with your s4/s5 n/a motor, a lot of work has to be done. basically a race built motor. wich sucks for a daily driver. and what good is a car if its for track only...no good. with a renisis you could leave people standing still and still have the the feel of a daily driver.



and as for the pictures, I like them.





Porting does not reduce reliability. You dont need a race motor to make good power out of a 13B. You have no idea about the time or money you are talking about swapping the motor.



Just street port a 13b w/ a good exhaust and intake. OH and tuning is essential to any rotary. If you dont want to do this I suggest a honda w/ lots of stickers and a huge wing on it. https://www.nopistons.com/forums/pub...1047683827.gif

Dam, i dont think it will be slow.



But I agree, turbo is better
