hey, Ive got a 91 2.4 DOHC car and i would like to swap in a SOHC possibly for the race track. I know the trannies are the same but what about the fly-wheel and such?? also does the whole wiring harness have to be changed?? or can i still use the SOHC…also ive heard theres two versions of the SOHC a 9:1 and a 8:6 compression ratio. How do i tell the difference?? I race a 240 at sunset speedway in the 4 cyl division and just looking for some information …any help would be aprecciated…thanks guys:
buy my dohc t25 turbo kit.
you will need the wiring harness, ecu, cluster, and a few other odds and ends. search this forum as well as a few others like zilvia.net and nico. this is a topic that has been covered many times.
peace
you need to swap the engine wiring harness and cut off the dash harness connector (cut and match wire colours), then you’ll need the ECU and gauge cluster and if you want your power steering to work, you’ll need the lines from the other motor… or modify your lines, but that doesn’t work for long usually.
clutch and flywheel are the same.
