Performance Upgrades

Hello, I'm new here, yay me.

Anyways, I might be getting a 95 J30, and I've already read the topics about the TT, which if I had enough money I might consider, but well, I don't.

I was wondering what some good Performance Upgrades might be.

It's an auto, and I have no plans on getting a different transmission though.

Also, does anyone know what would be involved in adding a single turbocharger?

Right now, my insurance costs are preventing me from owning a sports car, else I'd love to get a 300zx, so I'd prefer no comments about just getting a z, cuz well, it's depressing.

for the tt or just t anythings possible but you would need major custom work because the turbo just doesn't fit. in japan they have a v8 in the j try looking into that
