Hi from mass

sorry I meant renesis or three rotor my mistake... my motor is getting tired 105psi front 100 rear and renesis are fairly cheap and I want na for reliability aspect plus I really like na and plan on doing a time attack car. na 20b would be awesome as well but so $$$$. I had a Honda time attack car that I never got to run . I just like trying to get as much out of a na as possible! I guess im weird but I like na the best and I like trying to see what I can get out of an na time wise and rev wise etc.. I dunno.. I know its expensive so when it comes down to it I will more than likely rebuild my motor...

I hate to say this as I like NA engines as well, but to make power naturally aspirated you need displacement, which is big bucks. Otherwise you have to go peripheral port and put up with the trade offs on the street. Even then, 250hp is probably the outer limits and will most likely cost about the same as the 20B with not so hot reliability. You're only working with 80 cubic inches, so there's only so much you can do NA. The combustion cycle of the rotary helps, but it's still a small engine.

For a heavier car like the FD a single turbo, low compression ratio engine (running moderate boost) is probably going to be the most reliable rotary you can build. At least one that makes the kind of power you will need for the FD. Just don't make the common mistake that most others do and start putting together all the sexy go fast stuff on the engine and not do a massive upgrade on the fuel system and ECU. Without those any boosted rotary is likely to implode, no matter how good the engine build was.

yeah I agree the more I think about it the more I figure ill go with the 13b rebuild. I posted a build thread so you can check out what she has already.. It has pfc for ecu but needs a tune...
