my girlfriend bought me a Tbi spacer with the fuel line extention for my 91 camaro rs. I was wondering if I will run into any problems b/c i currently have the Edolbrock performer Tbi intake. I dont think so but Id like to know for sure before i take it all apart. thanks

 

Hmm, what is the bore size on the edelbrock Performer TBI intakes? Are they the same size as the stock TB bores or are they 2"? Anyways, if there 2" then you will run into a problem since the tbi spacer is made for the stock size bore of the tb. But I don't think the performer TBI is 2" bores on the intake so I think your safe. If for some odd reason they are 2" then just have a machine shop bore your throttle body bores to 2". BTW: How high is your TBI spacer? .5" I hope and not 1". If its 1" then your going to have to modify the cable bracket to have it go forward so your throttle cables don't pull open the bores at idle because their to far away.

The tbi spacer is from summitracing.com part # TRD-2433.

 

The Edelbrock Performer TBI has 1 11/16" bores, not 2".

 

Well then the bores matching up won't be a problem then. Just measure how high it is now.
