Purchased a set of twin turbo manifolds with 2 rebuilt Garrett T-61 turbos and hardware for my W116 450SE (1976).
Engine work done will handle the turbos and don't anticipate any problems.
My questions are,what should the timing be retarded to and what should I set the boost to (lbs)?Do you think I will need an adjustable fuel pressure regulator?
Timing is set at TDC w/vacumm! TIA
