I cannot recommend BW EFR, have tried 7163 in my MB E 320cdi.
Spools fast ~1600rpm =>
Gives a nice power.
Great turbo, in any meanings, but when I rice the fuel rate to ~500hp, it lasts about two hours.
Turbine slipped away ....
The price was outrageous and I donīt get any compensation.
Two hours costs more than two thousand, wonderfully expensive.
Some years ago I made two Mercedes with Holset 35, they work quite well.
But this BMW douple turbo system is far better.
I am going to built one to my MB with two Holsetīs, next summer.
