The FI controller failure rate is very low, the last one I read about that went bad was because some moron drilled a hole in the fender looking for a "cool" position for his antenna and got the box. Chances are it's OK. I really hope you're in a position to do some real detective work. If you've never seen a stock FI installation, you've got your work cut out for you. Hopefully you've got the Bentley manual with the circuit diagram for your year. The system is really simple once you understand it. There is/was a book about Bosch fuel injection systems that really had a good chapter on the D Jetronic, mine has slipped off the shelf and hidden somewhere, so I can't give exact details, you might try searching on amazon.com to see what pops up. Might be the local library might have a copy. Bentley also has some good pictures of the various components, might help you do rollcall. If you still have the pressure sensor,the FI distributor(extra plug on side), the original intake manifold and throttle switch, plus the injectors and original relays, you'll probably be OK. Oh and the original electric fuel pump, that's worth more than you paid for the car. If you don't have the pump or the distributor, probably better stick with the carbs unless you've got a donor handy. I hesitate to s&MO you might have to do to your apron to clearance for 4 tip exhausts. There's a wide variety of header systems out there, some take a lot of work, some just bolt on(very few). I have a dual QP installation, all I had to do was pull out on the mangled apron and get it straightened up to clear the dual mufflers. I really don't know what the PO had in mind, looked like he used a baseball bat as a roller and tried to roll the thing up. Chances are, you're going to have to do something to it, my advise is do as little as possible. You might want to wait until the engine is in the car before you mount it permanently. Try it on for size on the ground first, for sure, but take it back off and see where it's going to hit once the engine is in the car. On my system, I had to do some fairly major bending with a torch before the heater box ends and #2-4 ends all mated at the same time. Your front end has no doubt been adjusted for a "cool" look. My advise is to put it back where it belongs, it can really affect handling. Others will differ on that. I had mine about an inch too low, didn't like the way it steered at all. After a trip around the block I put it back to stock height. It's a fairly easy procedure, Bentley has it, but nothing to do outside in the cold.
