I am not trying to discourage anyone from trying to improve the Delorean. In fact I am doing the opposite. I only point out the possible problems that anyone who does these kinds of things will face. Many cars "out there" have been modified because of past problems. In some cases not by the present owner who is not even aware of them. If he was to by a product and install it there is no way anyone can predict what happens. A good example is ALTERNATORS. I am sure John H can tell you about all of the "defective" alternators that have been returned in perfect working order. Either they get installed wrong or the car has other (usually wiring) problems but the owner thinks replacing 1 part (the alternator) will fix everything. As for keeping spares, a bunch of paper clips, some fuses, and a couple of jumper wires with a wiring diagram will get most things going again. It just doesn't make sense to carry a spare for everything. In this case it is a part with a low failure rate. For anyone that does worry about their RPM relay I say just go ahead and replace it. Appreciate that it is just one of the many parts in the car that is over 25 years old. NONE of the parts in these cars was intended to last this long (well maybe the S/S body panels!).
