S50 and M50 injectors are the same green top Bosch 17.5 lb/hr units.

What year is the DME (brain) from? If it's from 1992 you definitely cannot use it. If it is 93-95, then you can use the DME, ONLY if you swap out the chip for a stock M50 chip.

its a 1994 525i 5speed car

I'm not quite sure why someone would swap out an s14 for an m50. Am I the only one that finds this weird?

Hahaha, so true MrK!

pray tell what your plans are besides a loss in performance and handling.
A well maintained S14, even slightly modified is much more fun to drive than an M50 and probably a good bit quicker too.

im using the m50 until i find a s50
but the m50 is also being used as a test motor to make sure the wiring is correct and the exaust manifold is modified accuratly ,etc...
