LT1 Throttle Body??? - Third Generation F-Body Message Boards

Blown89 · 11-12-2003, 07:05 PM

Dose anyone know if you can use an aftermarket LT1 throttle Body on a TPI car. I want to get the NOS 58mm throttle body and my buddy has a DFI so he said he has adapters for the IAC and TPS. Is that all i need? Will my throttle cable,TV cable work?
Any help is good help.

Thanks.

didn't see any N02 ready TBs on holley's site, that link is to the billet (read $$$) NA throttle body

that's the kit i was runnin on my 383, i don't see any advantages of the NO2 ready TB over the plate system except MAYBE simpler intall.

Well, its just as simple, just now that you need longer bolts. I dont see any TB ready for TPI cars... i thought I did.

The LT1 has a different cable "Arm" and also uses a different TPS sensor. The bottom IAC passages should be very similar, if not the same. I think everything would work if you were able to modify your throttle cable or the arm, and use the LT1 TPS sensor.
