I know this is not about turbo, but what would be the perfect compression on a B18c1 for a big shot of n20 using the NOS Plate system. Should the compression be lowered from 10-1 down to 9-1 w/ forged pistons, or better yet, would it be alright to run 11-1 compression? The block is going to be built w/ JE pistons and Eagle rods.

 

lower compression the better.
