I have a 1990 TT 300zx and i am upgrading my internals i am getting my pistons bored out to 88mm and i am upgrading turbos from t22's to t28's i know i am going to need new injectors but what else might i need for my car to run good. i am also wondering if my stock aut tranny will be able to hold up the power output that i am going to get.

Exhaust and intake are a plus. Boost controller to turn up the boost and an ECU upgrade will get you quite a bit of a hp increase.

the more important thing i want to know is if my tranny will hold

I've never dealt with the auto tranny on a z32. I did a quick google search and seen people claiming 400, 550, and 600 rwhp. I know z1motorsports offers a built auto tranny. You might be able to call them and talk to someone down there about it. They are very knowledgeable on the z32's.

Make sure you get bigger intercoolers and 3" piping, if you don't have that already.
