Hi.
Does someone know which injectors are best to use with a 1911cc engine? The D-Jet system is from a 1973 1.7 liter engine. I originally did not know that the engine had larger displacement and tried to use the VW black injectors, but those didn't squirt enough fuel. The yellow injectors were near impossible to find but I think those are also not adequate. Your thoughts? Share them with me. Thanks! |

Another thought....
You might also tee in a vacuum gauge with your MPS hose, just to see what sort of vacuum signal you're getting at idle. Maybe they swapped in a cam with more overlap and the MPS isn't getting enough vacuum. Inserting a small orifice (MIG welder tips work well for this) can slow down the vacuum signal, sort of averaging. That may make a difference as well. |

I think you're a mind reader sometimes.
Yes, the autopsy showed that it had a hotter cam in it now that I remember some of the details. I'm toying with the idea of maybe just selling the D-Jet as a complete running kit. I went through the MPS with a rebuild kit and verified its function with a Fluke meter. I'm probably getting ahead of myself. Maybe I should figure out whether I'll keep or sell the D-Jet assembly before I dink with it too much. I just didn't want to sell it unless I knew for sure it was perfect. Hmm... wish I had a 1.7 runner sitting here. Thanks! Another thought.... You might also tee in a vacuum gauge with your MPS hose, just to see what sort of vacuum signal you're getting at idle.
