nope alternators are different, not by much tho, and the version of the gte matters too
but you could use a 5S alternator on the GTE without any issues. MY GTE alt went dead & I used a 3s-fe alternator.

There are a couple of key differences.
Different connectors
Non GTE ones don't have the studs on the back for the cooling duct
Different amp ratings [autos have highest]
Also, it's possible the GTE internals [fans and such] are better suited for heat, but I'm not sure
