GTE altenator is a good upgrade for an NA.

You can always go up in amperage and not hurt anything.

Yup, but it depends on the model and year of the Supra (not as to whether it will fit, but whether it will be an upgrade).

Some GTE's have 70A, and some GE's have 80A, depending.

I use an alternator from the 89 turbo, auto trans on my 87 n/a. Just had to move the tensioner bracket a little, as the 89 alt. is a little bigger.
