When people do engine swaps like then it may be for a number of reasons. Maybe they like, the RB26DETT engine, but like the Supra looks better. Or maybe they want attention like Top Secret. Who knows. I like the power of Supra engines, cause once those cars go, they are GONE. And from what I know the 2JZ-GTE engines are easier modded. But suspension, and computers wise, the Skyline is more advanced. Put it like this. The Skyline is more of a track car, and Supra is more of a drag or top speed car.
