As you noted, I believe the 5SFE has a different distributor.
However, the 3SGTE turbo and 3sge NA use the same distributor caps, but there are 2 different types, early model and later model.
How to pick which one you have? If you look closely at the pics, the later model ones have
smaller center ignitor lead sockets than the early models.
Twos'rus have both types, including the tune up kit that should be ok for your car.
