1mz fe VVTI V6 into Celica Options

[Rooster92]

Howdy yall, i got a 94 ST and im looking to put a new motor into it, i was one with VVTI, and was thinking about the 1mz with VVTI, and thoughts on this if it will be a easy swap? I can fabricate most small things i need, mounts ect. Any feedback is appreciated.

There are a couple threads on the forum detailing the swap of a 1mz into a 6gc. If you use the search function you should find a few easy enough.

The biggest issue you are going to have is that the 1mz is compatible with the GT drivetrain, not the ST drivetrain. You're going to need either an E153 transmission(recommended) from a manual camry, solara or MR2 turbo OR a S54 transmission from a Celica GT. You also need axles, they will be hybrid axles if you opt for the E153. You will need GT or GT4 motor mounts to bolt the transmission in, and a custom fabricated mount for the front of the 1mz to mount to the frame/wheel-well of the car. The exhaust will need to be custom fabricated. You will need a 1mz flywheel and 3SGTE clutch. Finally you will have to either buy or create an engine harness to splice the 1mz's wiring harness and ecu into the existing celica harness. A standalone ecu is also an option but more work (you need to get it dyno tuned and the vvti wont work). There are some other considerations like the fuel pump, shifter cables, radiator but these arent as great of hurdles.

Its a lot of work. You could also consider a 4AGE swap, it wont have quite the power and the motor itself will cost more, but it would mate to your existing drivetrain.
