Jimmy although I have not tried it myself the plan is to put 150hp "shot" on my roommates 93 M5. I have it under go advice that a well designed No2 system will not harm M motors because of the high quality material used to manufacture the pistons. No2 sytem requires that proper air to fuel to No2 mixture remains. This means you need to make sure your have more than enough feul pressure. If you run out of fuel the motor will lean out quickly under No2 boost and destroy spark plugs and pistons. A "150 shot" is slang for and additional 150hp ontop of stock. You can do more than that but the fuel demands get tricky and a mishap is almost always fatal at +250 or 350hp. No2 is in my opinion a poor mans supercharger, but when you street race alot like we do, it's nice because you hide the system and then race for money and only use it if you need to in order to win. To answer your question I suspect that the other BMW motors will be okay with No2, but I am not sure what the pistons are made out of.
