This is Bill that was at Steves BBQ with the red hatch and LS motor? If thats the case, there is a reason why his car was walking all over that B16 powered car. He was telling me he had swapped out the stock PR4 slugs for some JDM CTR pistons.
With a stock 3 layer head gasket, the B18a/b has a comp ratio of 9.2:1
With a stock 3 layer head gasket, stock head, and block, but with CTR pistons, the comp ratio is raised to 11.4:1
HUGE difference in power tuned or untuned. I assume that is why even with you in the car with a GSR tranny he was able to pull away from the other guy.
same bill .... they are regular JDM B16 pistons though not CTRs ... i think hes around 11.1:1
