I've never seen or heard of it done before, heard people talk about wanting to do it and that abut it. I guess it would be just like any other engine swap you need to make motor and tranny monuts adapt the drive shaft swap in all the wiring harness in, exhaust, possibly bigger fuel lines and pump.
Sounds easy but theier alot of other stuff you gotta consider like, will it fit in the engine bay(ive heard supra motors are tall motors), if its oilpan is a front or rear sump(you need front), were the turbo sits because it might get in the way of something(like the steering shaft), will the shifter come out close to the stock location, will the tranny fit in the transmission tunnel, theris probably a few other things I might have left out. That applies to just about any motor you wanna put in, no one has done this swap before(on this forum anyway) maybe you can be a pioneer and be the first.
If thats too much for you and you want a I-6 turbo go the tried and proven L28ET route.
Am I the only person who responds to swap questions?
