Hey so my sister and I each have an 85 318i e30. The only difference is that hers is a coupe. While I prefer the practicality of the 4 door, the way it runs is much different. The main difference in that the coupe revs a lot higher than mine, once I hit 3000 or so revs my engine is screaming to change gears. I understand that the coupe is the sports model and tuned differently and lighter cause 2 doors less, but is there any way that I can have my engine tuned to rev higher similar to the coupe?
