    Exclamation Fuel Injectors

    Hey all, What is the stock rate on the fuel inkectors on a 95 M3? Is is 22lbs or 24lbs? Just curious. My friend told me that the pressure rate is higher in the 96-99 e36 M3's rather than the 95 M3's. What's the verdict?

    BJO, did you have to have a software change with the upgrade on your injectors?

    yes, you have to change out the chip when you go with larger injectors.

    The M3 is gone. I'll miss it but I love this E39 540i-6 spd. I call my rebuilt iX 5 spd. conversion 'my little red head' because she's so much fun to play with.

    I just bought a set of used fuel injectors off of a 98 M3. Is the fuel pressure rate 21.5lbs on these???? What else do I need to install these injectors? Is there instructions on the net to swap them out? Which chip do I need to make these work in my 95 M3??? Thanks for all the help.
