    TBI to TPI swap

    Anyone know about how to convert a tbi motor (88) to run a tpi manifold and injectors? Know anyone that can do the wiring harness? Any tips or info would be greatly appreciated.
    Thanks

    Get a harness and stuff from Street and Performance or Arizona Speed and Marine. Since a TPI is like 3 or 4 viable choices ago most here won't have recommendations.

    Well after looking for some tpi manifolds and wiring it will be cheaper for me to just get a LSx motor. A good friend I went to school with owns a local junkyard and has a good size van full of LSx truck motors he said I could have any of them for around $500, complete motors but no wiring harness is attached to any of them. Thank anyway man

    you really saved like 3 or 4 members here some time to post up to go ahead and get an LSX motor. Good choice. DBRODS on here spent LOTS of money and time reworking his TPI motor, heads/cam/the works, and it still only ran 14s. Went to an LSX, with the same amount of work done, he ran a low 12 at 110
