What is the difference between the 92-93 throttle bodies and the 94-96 throttle bodies. Im looking to buy a 58mm and id just like to know? Thanks

 

The early throttle body has a provision for the TV cable for the non-electronic transmission and a different IAC.

 

so can i not use a 94-96 tb on my 93? I have my stocker to steal stuff off of if i have to.

 

You won't have any provision for the TV cable, unless you can figure out how to convert it somehow.
You could swap out the bottom coolant plate to be able to retain the 93s IAC. Otherwise, you will have to change the electrical connector on your engine harness to fit the later IAC.
