    280/278, too much overlap. Going with a different grind anyway.

          Hm, I took a look at the Euro M3 kit.. all well and good, but peak power @ 6100 RPM doesn't make much sense on that engine: could you elaborate? Thanks!

                      I had to move the abs back a little and bend new lines. That's if you want to keep the abs. Also had to move the coolant bottle to make room. These are pics once it was installed. Cleaned the engine bay up and nothing is twisting now. Here in TX I pass the smog test without breaking a sweat
