heads up to all you m50nv's about crank position sensors.

If you lookup a crank sensor for a '92 325i at advance auto parts or autozone, they'll give you the sensor on the right, which is a Hall crank sensor for a vanos engine. The one on the left is the more expensive VR sensor from a late-model m20-engined car, which neither store will usually stock, but can order - but if you need one in a hurry, you shouldn't have any problem grabbing one at the yard.|

I should have stated also that the reason I bring this up is that the sensor on teh right (hall sensor for vanos engine) will obviously not work in a m50nv with a 402. It'll run with a 413 ecu, but it'll be rough.

You need to be more specific when you say VANOS engine brah. The m50TU and s50US are OBDI and VANOS, both use a VR type crank sensor. S52 and m52 and all subsequent BMW engines use hall effect sensors on the crank.

So are you saying the one on the left (m20) is the one to use. Im all squared away, just wondering.

I guess it would be wise to take the part and/or part# with you anyway.

wierd. what ecu and where did you get the sensor/what model car did you give em

I just ordered it from Pelican, I'm running a 403DME on my NVM50

you're fine then, you're already using a VR sensor. this was for people ordering from autozone/advance/napa or any local place.
