Re: Will 89 tpi parts fit a 86tpi setup
So far as I know there are two types of TPI...... 85-89 and 90-92. IIRC all the parts from the same vintage manifolds will interchange. Besides that the only difference is that corvettes all used one fuel rail and camaros/firebirds all used another. Corvette fuel rails terminate on the passenger side and camaro firebird fuel rails terminate on the driver side.

The runners should fit.
'89 didn't have the cold start injector like the '85-'88 MAF systems did. But that's in the plenum.

If you have an 86 setup, 89-92 runners will work, but youll need to plug your fuel rail where the 9th injector comes out of. And you will need an 89-92 plenum as well.
Is this all correct?
