2.5 TBI swap to mpi

Recommended Posts

So I know its been done before. I have the 86 tbi, will I need the later flywheel? I know I need intake, wire harness, speedo?


Yes you will need the later flywheel. I believe you will also need a new fuel pump -- I think the operating pressures are quite different.


Why would you need to change the speedometer? Yours is mechanicsal and it's driven by the transfer case -- it has nothing to do with the injection.

It was easier for me to use the MPI speedo since its plug and play with the MPI harness.


however if you want to use your old speedometer you need a pass through speed sensor so you can have the speed sensor signal for the computer but still have provisions for the cable operated speedometer.


There is a bit of info on the swap in my build thread.
