    M4/S55 Turbos

    I'm assuming they will be bigger then the N54 turbos with the numbers advertised by BMW, they should in theory bolt right up since the head ports are the same, may end up being a cheaper/better way to get cheap power out of the n54 then the vargas/similar larger wheel modification products. Thoughts?

    They use electronic wastegates. Completely different. If they could somehow modify existing wastegate design into the turbos, it might be possible....but why go that extra length when there are plenty of stock turbo housing upgrades out there already?

    They will not fit, actually they are not even close to fitting. I made a post a while back pointing out all the differences, I forget what they are all now.

    The JB could control the gates but I doubt the turbos are better than say RBs. I should have one in a couple weeks and can't wait to throw it on the dyno and get starting on its tuning.

    Just looked at it again, for starters both turbos are facing the same direction, meaning nothing from downpipes, to charge piping, to intake, will fit, the list can go on quite a bit of other things that make them incompatible. This is not a viable option.

    At least BMW realized the pancaked intake piping was stoopid Click here to enlarge

    Please please let me know Terry. I'm down the street from specialty and I would really love to see that in person.

    The aftermarket already has better options and S55 parts won't be readily available for some time. Why even bother with OEM stuff anyway when you can get better?
