I have a 91 camaro rs TBI 305. i was wondering is a new throttle body worth it? 52mm or 58mm, or would a throttle body spacer work?

 

Save your money...The heads & cam are the restrictions on the TBI 305.

 

do you mean tpi? i dont know of any other size throttle bodies availible for the tbi

 

Info:
There are different size TBI thottle bodies and various perfomance parts for this FI system.

 

ok, i just wanted to make sure. i know the tpi has the 52 and 58mm throttle bodies availible. i thought the tbi units were typicly measured in cfm, like a carb

 

Hey, A new throttle body is not worth the money, also it's a pain to convert to a 52'' or 58''. I bought a 52'', it wasn't worth it, you can just replace the bearings. you have to convert the intake hose for a bigger throttle body and it's a hard part to find. So I would save your money...
