If you find a donor turbo car, get all the parts you need so it will be stock.
You have to get everything including the wiring harnesses if you don't want to spend many hours of rewiring the components.
When I say complete setup, I mean everything from the air induction, wiring harnesses, relays and solenoids for air by-pass, fuel press regulator, intake manifold, etc.
From the workshop manual, the 87-89 626 turbo distributor feeds a signal to the ECU for the injector batch firing.
On the later models, I am not sure of the set up. You have to get a workshop manual for those specific years.
