View Full Version : 2.2 block - 2.5 computer

I will be running an '86 2.2 in my caravan with the stock 2.5 computer, '89 intake and garrett turbo (until I can find an '89 2.2 computer) . Will I have to worry about detonation or running too rich ? Should I use the 27 or 33 injectors ? Any advice on this setup ?

Well the 2.5 runs 20% richer so I would use the 27's. Also, the 2.5 has a less aggressive spark advance so you could probably give it a few more degrees base timing, :nod:
