Would injectors designed for a Volkswagen VR6 (lets say a 1993) fit an M50 non vanos? I have 310cc injectors, ~30lb/hr, let over from a Vr6 turbo build aand im hoping i can use them

[winfred]

they may be too big, the stockers are around 17# it takes a little while for my 325 to adapt to the 19# injectors i have in it after a computer reset, i am not sure that the computer can handle dialing the pulse rate back that far

They will physically. Im pretty sure all gasoline MPFI use the same injectors. I had 30lbs on my 92 525i turbo and they worked, but it drank gas. Just make sure that when you have the turbo or s/c setup installed that you get a chip programmed for whatever size injectors your running. Oh, and the MPG guage will be way off, it will say that you are getting 40mpg in 2nd gear at 45mph and 4500 rpm.

I know I need the chip done, but I want to make sure these little guys will fit. I have a pic.

Yea, i had the same ones on my car, i think they are originally from the early 90s ford 2.3 4cylinder T-Bird and Mustang.

And you confirmed that they do in fact work? Do you know what impedence they are?

[bjl4776]

They are high resistance 14 ohms, and I am positive that they work, because I had them in my car.

Ok nice, I will use them. Now... to figure out how to tune them. Should I runa Rising Rate Fuel Pressure Regulator? It came with the supercharger, but larger injectors did not...

[bjl4776]

I would use the RRFPR in conjuction with the FPR, just make sure that it is adjusted to about 3-3.5 bar at idle. Most of the tuning comes from the computerized aspect of it, the FPR will just help with the amount of fuel that you are going to need once the engine comes on boost. The rising rate isn't as necasirily as big of a need for a s/c than a turbo because the s/c always has soom boost, but a turbo kind of kits you at once, but if you have it then use it, it won't hurt.

[bjl4776]

Were are you located I would love to help you out, Iv done a couple turbo setups on 525i and 325i and I miss the feeling of boost since my accident, its addictive.
