Can you use M50 injectors (i think they're 17lbs) in the m20 motor for a 325i if you're using a markD chip?

Yes, as long as it is the chip which is intended for 17 # or 19 # injectors. It is the same chip. If it is the chip for the stock 14 # injectors then you need to use the stock e30 14 # injectors. -
will i get more power with bigger injectors and chip?Comment

The chip will allow for more power since it will make the fuel and timing maps more aggressive. The larger injectors are not necessary from what I understand (unless you have extensive modifications like a stroker kit and large cam but even then I am not entirely sure where the line is drawn on when you need larger injectors). The benefit of the M50 injectors is that they are a 4 pintle design which is supposed to provide better fuel atomization. I would guess that rebuilt/cleaned M20 injectors would allow for more power than any old junkyard M50 ones though. To me the priority is good clean injectors and not so much injector size.Comment
