Trying to get my barn find 75 1.8l running and working on my FI education.
Looking at the specs on fuel injectors has me confused, L v D jet. From what I'm reading, I can't use D-jet injectors with L-jet system. I currently have a mismatched set of injectors in the car, 3 from a 912e and 1 from the original 1.8. I have a really nice set of yellow 1.7's on the shelf, guess I can't use those....(anyone want to trade?) |

But you really need a complete matched set. |

D-jet injectors have different electrical connectors than L-jet injectors. I don't think you could swap them if you wanted to unless you spliced the corresponding connectors on the harness. . .

L-Jet system doesn't have enough voltage at the injector to fire a D-Jet injector. The resistor pack is to lower the voltage at the injector. |
