A buddy did an N/a-t MK3 supra. He was able to use the 7MGTE wiring, and electronics, tweaked to fit, and used a stand-alone ECU called stinger from austrailia. If you plan to do some boltons the GTE would easily be more expensive. Cost of motor is way high. Then you plan on doing the same upgrades that you did on the GE, which is cheaper. Such as putting the header, turbo, downpipe, stand alone, injectors.....ect, then really all your using is the basic longblock, not even the full motor. But I guess if you get a GTE you could sell some parts off to make a bit back.
