I’ve heard the stock manis flow 600whp but its just one of those mind things you know? lol… As for the turbo, I DEF wanna go bigger than evo III and YES, I wouldnt mind not having to build the internals aise from cams which I want, but if I go bigger than an evo III it’d prolly be a good idea if I did the whole 9 yards to be safe no?.. I’d like the car to run consistant mid to high 10’s on street tires.
