i am thinking about getting NOS for my '98 m3 sedan. i was looking at a 75 shot dry system. my car is automatic. one of the main reasons i want to do this is because my friend with an s4(manual) is getting a chip for his car and now he is talking a lot of smack about how he will kick my butt. i have a limited amount of money to spend, thats why i cant get a turbo or supercharger. if anyone has opinions on NOS please let me know. thanks!
