K20 piston question
Can stock k20 pistons fit on LS rods? If they can what compression ratio would they yield?
I was thinking of putting k20 pistons on LS rods in a b20 as a cheap way to up compression but I am assuming that it can't be done.

no the answer is no , and your damn sure not gonna fit k pistons in a b20 block - deck height is different k is 86mm b20 is 84 there would be alot of custom work needed for u to even think about building a 86 mm b series

Deck height isn't a factor - that has to do with the K20 block, not the piston. The compression height of a k20 and a b series piston like p30 is the same at 1.181. The issue is the pin size. K20s use a .860 pin, while the LS/B series has a .827 pin.

i thought the k series block was 87x87 mm. i know its square bore. either way you would need a ton of sleeve work to make the bore useable, a really good head gasket to seal the thing, and like nick said, u would have to find a way to make the pin work. perhaps a set of custom rods. your best bet is the rs machine itr copy piston that they make for b20s.
