well adding in things like the heat we have down here and gas quality u need more than a headgasket when running 20 plus psi but that's a good I idea to help with the built also drill the bock to fit 4agze arp bolts
@lukep its about lowering the compression and running lots of psi. @morgey yea the vitara piston seen to handle a fair amount of psi some people down here take the standard gt pistons and shave them to run more boost
Thanks for the info i would have to get one piston to test. I know comp might be higher due to manufacture differ,but i was askin because i know hondas use vitara pistons an i know a guy that fitted vitara pistons in his 5e (covers eyes)
anyone ever used honda pistons at 9:1 comp in a 4e and 5e. Are would i have to be the first mad man to try it jus need to know bout the wrist pin size ohh the piston r 75mm
@shorty do u have a set of the first production r the second and r u sayin all of the second production r bad i read that they were machine instead of being cast is this true
350 d highest im aming for still need it to spool fast as i like goin around the track one r two drags but more track. i see u have a pic of the 18g what rpm it starts to spool?
