Was wondering if anyone could tell me if there are any PERFORMANCE diffrences between the First and Second generation JDM B16A's? Basically if I have a B16A from a 1992 SIR, and a B16A from a 1998 SIR, with the same amount of miles, is it the same (other than more engine codes?)? What about the tranny? Any differences there? Thanks for any help. If this topic has already been delt with (which it most likely has) please put me in that direction. Thanks much.
