hopefully nobody flames me but i have an 05 scion tc and im really more into the wheels and fitment scene but it has about 85,000 miles on it and i was thinking in a few years instead of just running my engine down i could swap it with maybe a supra engine or a is300 motor... anybody know what motors would fit and if anyone has ever done it??
Being that the tC is FWD and the 2JZ is for RWD, it won't just bolt up. I'm pretty sure your only option would be to convert your car to RWD because the I6 is too long to transversely mount into the tC.
Money can make anything happen, however with the limited space available for a drivetrain making the tC work with such motors would cost a LOT of money. To even get a "supra engine" to work would involve making the vehicle RWD.
Simply put, no, it won't work. And just because your car has 85K on it by no means says the car is anywhere close to worn out.
