What other bolt-on performance parts should I get? I was thinking of Throttle Body Spacer and pulley. Anybody recommand them? Are they worth the money?

 

A throttle body spacer is a total waste of money. I think Zabtech now sells underdrive pulleys that keep the alternator spinning at the proper RPM. I have the PHP alternator pulley (that's Pauls High Performance), and I just raised my idle speeds to keep the alternator spinning up. Gears and t-lok would be a good option for you.

 

+1 to the throttle body spacer. Spacers really only work on carb'd cars.

On the other hand, you could go for a Zabteck Throttle Body which looks like a nice piece, also T/Lok ang gears and what about control arms??

 

The general consensus is that throttle bodies are pieces of crap. Yet, the Zabteck throttle body is one that people swear by for modest results.

 

That's because it is a factory piece that has been reworked for better airflow(boared out, new butterfly etc..). This way there is no issue with it's mechanicals. It won't give huge increases but if your looking for every last bit, it's a good choice.

 

3.73 gears w/ t-loc....OR an 8.8???(unsure of the height) Gt take-off rear end.
Aluminum drive-shaft replacement.
lower control arms......
