Hey just wondering if anyone knows if there is a difference in compression ratio between the non electronic 4jg2 motor and the electronic engine?
I know the 4jb1 engine has lower compression as this is a direct injected engine. There are apparently 3 types of pistons used in the 4jg2 and they are coded with either a square circle or triangle just trying to get some more info as im looking at building a new engine up atm
