m50 injector test help please

[88SuperETABD]

I'm trying to figure out what these injectors should read, I know m50 (green) injectors are hi impedance (high ohm) so they should read somewhere between 10-16 ohm resistance when hooked up to a multimeter. I wanna make sure all 6 are good before I install.

I searched to find this number, but failed to find it.

Anyone know? Or got a link to find it?

Heres the part number of the injector if it helps.

Bosch 0280150415


Thanks in advance.

Fiveomotorsports.com list the 0280150415 part number for those M50 injectors.

either in the 14's or 16's. Start with one and you'll figure it out pretty quick I've done quite a few of them and yet to find one out of spec. Also if you search on google there will be a link on the 1st page with the info.

I searched...theres no specs...

link to said "specs"? It technically should be 1 number. It should have a certain resistance when new.

Witchhunter.com is a good place to start looking for specs

Nice! thanks! Its supposed to be 15.9 Ohm.
166 cc @ 3bar

So that means on a m20 with a normal 3 bar regulator, the m50 injectors would be 15.81#'s instead of 17.5

Smart of you to notice that, a lot of people don't figure in the difference in pressure between the engines when calculating injector sizes.

So I went and bought a multimeter cuz i couldn't find mine. Was a 15$ kragen one..dunno how accurate it is, but i got 4 injectors to read 16.2 Ohms and 2 injectors to read 16.1 Ohms. I'm guessing this is okay. Its a little higher than 15.9 but I'm sure there is a tolerance for the multimeter or the injectors themselves.
