The ITC car ('77 Rabbit) that I bought, was at some point in its life, converted from fuel injection to a carburetor. I would like to return it to fuel injection. Because all the fuel injection parts are gone, I feel the lest expensive way to get the parts is to buy a parts car. My question is, are all A1 fuel injection systems the same, or is there a specific year that I must use? Would a system from a GTI be legal (I would like to get a close ratio gearbox also)?
