I have a Samurai with a Mk1 swift GTI engine fitted and using the angle dizzy drive. My question is can I drop in a MK2 engine, assuming I swap the dizzy and angle drive over, or are there other sensors, perhaps AFM which also need swapping across to make it work with the MK1 loom and ECU?
Appreciate any guidance.
Thanks

pretty sure you would need to run the mk2 ecu and loom
