What size bore is the TBI on the Camaro RS? I want to get a spacer from Turbo City (www.turbocity.com) when I get my car. Is it 1 11/16" or 2"? Will a 1/2" spacer have enough clearance under the hood?

Also, is the TBI unit in the LO3 the same one that's used on 5.7L GM trucks?

And a side note, how many cats do 91' RSs have?

Any help would be appreciated, Thanks

 

The RS bore is 1 11/16"

I have a 3/4" spacer, it fits with a non-drop 14x3 open element.

The TBI unit is the same on 350 trucks, but they use 55# injectors. TBI cop car (RPO 9C1) caprices use #65 injectors.

A 91 RS has one cat.

Speaking of cop car injectors. How much is a good set of 65#'rs worth?

I won't need mine after I convert to MPFI.

That's how I roll Snuffy


Off-brand 9C1 injectors are about $50 each. I'd go from there.

 

Kewl. Thanks Mac.
