as far as i know this is how its always been

no boost leak, as when we gae the car a resto he used some milkalor clamps which just leaked there arses off, we have pressure checked it to 32psi and not a single leak anywhere

when we had the sump off alls we could see is mahle which id say were std pistons

my old car was 7.2-1 comp ratio and i had no where near asmuch turbo spool as this has mine was virtually instant this is kinda flat ntil the turbo actually gets going which im finding strange
