ok so i was on endyn's site lookin at rollerwaves and i noticed that the B16 selection was broken into two parts, B16A(all) and B16A(with B20 connecting rods)
so i did a search and came up with nada, what's this buisness, what are the gains, what displacement could you expect and how does it affect compression?
heres a link.
