Out of interest will the ITB's from a 3.2 work on this head?
I believe that they dont point the injectors correctly but Im not sure? Would be keen on looking at doing that to my car.
The bottle neck is at the valves on m50/52 motors so yeah itbs will work but the gains will be minimal. Cost wise it's not worth it. Rather just use the whole 3.2 motor and not just pieces from it.
