I have a bbk 75mm tb with a bbk intake. I didn't notice much change in power after I installed the tb. I was wondering if an aftermarket plenum would help the tb reach it's full potential or if it's worth it at all.

75 mm tb is WWWWWWWWWAAAAAAAAAAYYYYYYYYYYYYYYYY too big for your car, Im suprised you didn't lose performance.

SHould I put the stock tb back on?? I really didn't know what size to get, what do you think about the plenum?

plenum isn't a bad thing, but i would finish up your exhuast first. i will help out MD on his statement.

75mm t/b is wwwwwwwwwwwwwwwwwaaaaaaaaaaaaaaaaaaaaayyyyyyyyyyyy yyyyyyy to big.

With the mods listed in your sig, you have alot of other good mods out there you should be doing before a tb & plenum. Your heads and intake don't flow very well at all, and they are your restriction - not the tb and intake. So, work on the exhaust side first - like mid-pipe and / or longtubes, a CAI and pulleys as well is a good idea and could be done anytime.
