I have alot of money set aside for this car, it will be my first project car. I was planning on using my 335i and now I have to wait again..........it's getting painful.
Im confused.. You are using your 335i as a project or you are waiting for the 135i? Is your goal 500whp? What is your plan for achieving this, if you don't mind me asking?

Imo the greatest advantage of DI is how fast it can get the fuel in the cylinder. The more time the fuel spends in the cylinder, the greater possibility for pre-ignition and detonation. The next greatest advantage is the fuel is injected in vapor form(a great side effect of how fast its injected) and atomizes very quickly with the intake charge.

Does anyone know if BMW uses individual cylinder knock control?


All this talk about motors and turbos has me excited for this

I can't wait to see what this technology is capable of.
