If you use an 81-84 block you'll need an 83-84 EFI head. If you ue anything
85+ you'll need 85 head and block. The 85 EFI isnt that hard to work with. Wiring is pretty simple actually. Buy an '85 Toyota truck service manual and have at it. All the info need to wire it up and make it run properly is in there. you can use 82-83 EFI Supra, Celica, Cressida. External Fuel pumps and the existing fuel lines. just be sure to wire in a fuel pump relay between the "FP" ECU wire and the pump. the ECU cant handle the required amps to run the pump. only enough to activate a relay.
