I had a 94 camaro z28 and bought a holley 58 throttle body for it. I'm buying a 93 camaro z28. Will it fit okay. Or do I have to order a new one.

 

It should fit but you will need to get your intake manifold ported to fit that big of a TB, the biggest that will fit correctly on a stock intake is 52mm

 

if you have a manual tranny it will work fine

 

Well you see I have a 94 camaro I bought that for my camaro. I just sold my 94 camaro m6 and bought a 93 camaro z28 automatic. The 93 camaro I bought is a race car. The intake has a bbk 58 throttle body already. I wanted to replace it with my 94 camaro holley 58 throttle body. Because Holley is a way better throttle body then the bbk. Could I do it - Mike

 

The 93 a4 throttle bodies have a connection for the TV cable. The 94's dont have this cable.
