Does anyone know what is the Toyota Part Number for the high amperage alternator that comes in the 91 turbos?

I wasn't aware of an alternator change through the MK3 generation. I know that the MR2 alternator for similar years is a bolt up high output alternator, but wasn't aware of any of the MK3 ones being different.

make sure you have an 89+ supra pulley for that mr2 alternator. 86.5-88 shaft is a different size so that pulley won't fit. the pulley that comes on the mr2 alternator won't work either, i think the grooves are wrong or something.

agreed! what i did is i took my old pulley and the mr2 pulley to a machine shop, and had them enlarge the hole in my pulley. works like a charm!

Depends. Early 87 was 70 amp, later 87 was 80 amp.
