im thinking about adding crower stroker kit to a GS-R motor and putting it up to 2.1 Liters instead of the 1797cc. stock motor , and maybe then supercharging it. ( with cams crane stage 2 cams and port the head out) Is there any problems with stroking a GS-R motor , like will i still have sleeves for the pistons? someone told me it can be a bad idea. Also, i was wondering what the redline is on a stock prelude motor and maybe a lude motor with Type-S or equivalent cams and ported out. THanks!
