Hey I have a 99 gt 5spd and I want to go to a 4v engine since my plan is too TT it what would all be involved with the swap I asume I will need a wireing harness and gauge cluster but I am sure there is other stuff involved with the swap can any of you please enlighten me

well what year 4v are u swapping in, cause if you wanna do a TT and u dont have a terminator block your probably gonna pop the motor, you will need the ECU, wiriing, and the complete motor, correct length throttle cable, and a flywheel to correspond with the different bolt patter on the crank.

you wouldnt need the ecu or wiring harness if you have a good tuner

I have quite eextensive dataloggin skills so the ecu should be a problem Its aaccualy part of the reason I want to do it because I want to do somthing new all I have really been doin is subarus supras and diesel trucks< dont ask where it came from. Anyways thatnks for the help man oh the the engine is out of a 03 mach 1 that was tboned

False, you can use the gt computer and harness, but ONLY if you delete the IMRCS, the gt computer will not open them. So if you dont plan on deleteing the imrcs you wont put down any power
