hey there

i have a '79 e21 320i that has had a carb from some unknown origin put on it. as far as i know, this conversion has made the car less powerful and maybe made it thirstier as well. i am interested in converting it back to a fuel injection system. i think i'll be needing a bosch k-jetronic or something similar. i am interested in the costs for such a venture and basically any relevant information regarding this job. please reply with any sharable wisdom!!! cheers.

Bolt on an E30 motronic fuel injection system from a 320i and fit the motronic 1.3 172 ecu, more economical and more power, also you can chip the ecu... or use the inlet manifold from a 325i using again the 172 ecu, NOT the 173 cos it will over fuel and causing bad economy and driving, you will get more air into the engine cos the manifold and throttlebody is larger so midrange motorway driving would be a pleasure. a.k.a. happy days
