I have noticed that the intake manifolds, 670 cfm Holley TBI unit and other Bolt-on performance upgrades always seem to stop thier applications listing short of the 1992 TBI usage. Anyone know why? The Holley 670 CFM TBI unit for example says it's only for up to 1989 models (trucks at that).

Thanks,

I think 1992 was one of the lowest number prodution years. Maybe they didn't want to pay to have it certified? I can't imagine it being much different than the older ones.

i dont think they are different

The Holley will work. I have a '90 TBI and use it. Do a search to find more info on it.

The TPS connector is different. You have to get the part in my sig for your TPS to work.

Yeah, I'm pretty sure the only difference is the TP Sensor.

Yeah, and the TPS on my car has been replaced TWICE since I've had it. 2 times within a year. ****ing piece of ****.

hey snowdog, where'd you get that ram air hood at? i've got a red 91 firebird and i think it looks awesome on yours.
Thanks

The ASCD Hood can be found on this page:

I highly recommend it.
The TA-500

is it most effective with open element?
and, does it come painted or is it just primered (sp?)
