You have to admit, the Supra makes big power cheap. But the Z has better styling. So lets throw our prejudices away and enjoy the best of both worlds. I believe the Z engine Can keep up with the Supra, but the supra was made a few years later with the intent to copy and beat the Z. The Supra engine has real strong internals and seems to be pretty reliable. I just never would have dreamt it would fit. Hell one guy through A Gran National Turbo engine in his Z and made killer times. I'd rather have a toyota engine then that. So anyone know a price tag on a project like this?
