TPI Injectors on LT1
HI I am doing the lt1 intake conversion on my 89' and I wanted to reuse my TPI injectors on the LT1 since they are brand spankin' new. Is it possiable, if so how do I do it.
Also I bought a Professional Products polished 58mm throttle body for the 89' TPI for now. when I get down the road will I still be able to bolt that same throttle body up to the lt1 intake manifold.

Return it or resell it -- until you're getting above 400hp. You don't need the extra flow yet. (IF you do use it, this will also need to be part of the tune. Without a tune, a bigger TB usually results in disappointing low-end performance. Tip-in adjustments are required (via tuning) to compensate.

The injectors will work.The throttle body will bolt up and the likage is the same but it may or may not work properly at idle. LT1 TBs I've seen and dealt with have an extra hole tiny hole drilled through the face of the TB just below and between the throttle plates to allow more air to enter the intake at idle. But since your application is a " coversion" it may not care. Might be worth a try.
I agree you'll need a tune as mentioned above.
