If you're talking v2 1996 .It's the forged pistons and ecu tuned for an extra 10ps .I'll have to double check my cam profile data I can't remember if the cams had more duration and less lift on the sti. It's the sti v2 ra engine you want. If you can find one.
Intake Manifolds on V1/2 can't directly interchange with v3/4 directly as the tps and idle valve are different but could be used if modded
