i need part#s for a tbi 350 injectors, ecu, knocksensor, IAC, throttle position sensor, and are any of them the same on a 305 tbi setup on 1989 rs. also is there a big difference in the intake and throttle body size between the two

 

you probably want to get the 65 pph injectors and a prom for the police package (9C1 i believe). Youll also want to get a new knock sensor and est module for a 350 also. I got my borg-warner knock sensor for 45 bucks down at pep boys. Everything else is pretty much the same. I dont know all the PN's but im sure someone else can give them.

 

350 injectors ----------------(#17112493)
350 ESC module ------------(#16128261)
350 Knock Sensor ----------(#10456288)

If your car is an automatic, you should get a custom chip off of a police caprice package 91C.

Good Luck, eh!

 

Use the same ecm, just get a chip for it.
TPS is same
IAC is same

Any questions, just email me RSCamaroGuy92@yahoo.com
