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...
