i have a 95 talon what size throttlebody should i upgrade too i want as much as going in as possible

 

What are you mods? You know that question is going to be asked later, so I figured it best if it was on the first page
Anyway, IMO, with the stock manifold, go with a 60mm bored 2g TB or stock 1g TB. If you've got an SMIM, you have an option of a 70mm. A mods list can help us help you with that though, a list of "real" things to come will help too.

 

Shouldnt we know if its a 4g63 or a 420a, first?

 

That's true! Iif that's the case, a 55mm works.
