I have a 92 gta L98 I have replaced the injectors with bosch 22lb injectors. The question I have is that I have a BBk Throttle body (52mm)that is new would the gain be worth putting it on my car? The other question is do I need to do anything else to run it. The motor is stock,but it does have a jet super chip, headers, 2 gutted converters and a 3in. cat back exhaust with a cold air kit. Any help would be apperciated!!!

 

There won't be a gain installing the larger TB if all you've got is bolt-ons, and you'll lose driveability at part throttle. Save it until you do a head/cam swap.

 

I would install the TB and see what happens. If you really loose anything all it will cost you is a gasket to go back to the stock one.
