p.s. my mechanic advided against it but did add the 75hp was not too aggressive and I would "probably" be fine. 100 hp and over was defintely not suggested.
You should speak with a BMW mechanic before doing this. A friend of mine, despite warnings, did it and blew the motor on his car (a BMW 530). If you want to keep your car, this is the least desirable method of improving performance. Cheap horsepower often comes at the expense of mechanical reliability.
The other posts have adequately explained the drawbacks to nitrous. Makes perfect sense when you think about it. The pistons of an engine, together with the valvetrain and other internals and the rest of the drivetrain, are designed very carefully to provide a certain amount of power and to withstand the forces created by the engine in creating such power. When you change one of the variables in the motor, i.e., the force of combustion, without adjusting the others, you are more than likely to, at the least, severly shorten the service life of the motor (more wear on valves, pistons, rings, etc.) and at the worst, blow the engine entirely. Plus the fact that nitrous is not safe in the event of a severe accident. To be totally honest with you, I would not even do business with a place that sells the stuff unless they sold it only for non-street racing applications. In any other situation, in my honest opinion, selling the stuff is irresponsible because it is dangerous and unsuitable for street applications.
