I am going to be replacing my injectors with a 42lb Mustang type injector. Does my e36 M42 run low or high impedance? need to find the right ones to do a direct swap.

FYI i know the are bigger and i am using a fuel management to use them.

high impedance, from what i'm reading 42lb is way overkill unless you plan on making over 300hp

+1. High impedance & looks like PN 0280155968 is a pretty common choice. You'll be sharing them with high pressure turbo Volvo's & Porsche 928's:

Injectors that are too large will cause you some idle & low speed troubles. Depends on how big that blower will be, I guess.

I will be running 15psi I went with the 42 Lb Mustang injectors. Just wanted to make sure the mustang ones would be the correct Impedance.

Thanks guys
