What will you use the car for? Pure street, or a mix of street & track?

What max HP are you looking for?

The GT30R is an awesome street turbo and will be *very* responsive on a 3.3L, however, be warned that it will top out at just above 400-420HP on an air-cooled Porsche motor.

If you want a bit more top end than that, I'd recommend the GT35R. That's what I use and it's an awesome turbo

Mic's right though, you will have to modify your muffler inlet flange, run a smaller oil feed line and modify the flange on your oil drip tank. A bit of work to make it fit, but the GT's really are awesome turbos.

If you don't want to go through all that trouble, then stick with a modern K27 drop-in upgrade.

One thing is certain, to get the most out of the turbo upgradem you reall need to run some aftermarket headers and a nice free flowing muffler.

Good luck!
