The throttle body from a GM 4.3 should be about $30. Holley TBs are like 5 times that. Used ones are just as good as new, I don't see the Holley unit being worth the cash.


Being a pessimist, I'm assuming that at least some parts (injectors, IAC, etc.) would need to be replaced during a rebuild, which would add a couple hundred $ pretty quick.

EDIT: Printed out the write up and read it last night. The injectors and IAC get reused from the 2.8 TB - sure makes this option look better!

I might luck out, but Mr. Murphy and I are old friends! <img src="/forums/images/graemlins/lol.gif" alt="" />

Also, Make sure you do something to your exhaust since this mod should go in conjunction with something on the other side.


Took care of that when the muffler blew out, high flow 2 1/4" cat and turbo muffler, 2 1/4" pipe from the "Y" out the back.

Really incredible improvement in power, might I add, for a simple and cheap mod.

here's my writeup...


Thanks...
