Hi All -
After I started this thread, I had an opportunity to pic up a 2010 LeMans blue 135i with the n54 and a manual transmission really cheap.
So I'll start doing some modifications to that in the near future and keep it in my back pocket in case I need to build a race car in a hurry. Plus, I still have some wheels, suspension, etc. stuff left over from our 135i race car days.
But I hear they are going to start putting the M4 engine in the M2. Do you guys know if that's true? If that's the case, I'll wait for that before starting an M2 race car.
