Hey Willy,Welcome to the forum,I Plan on doing the same thing only I have a 92 TPI going into a 93 s15 with a 4.3 CPI.Heard you can use the CPI wire harness and I would guess the computer would work also
GOing to look into that tonight and see what find,wire harness would just need a few little tweaks I hear..Might want to look into the vette servo to help with the shifts...Let me know what you find out and I will s do the same.
