MGT2256S Billet Turbo - Upgrade for BMW N63 V8 — Overview

This is an MGT2256S-based billet turbo upgrade intended for BMW N63 4.4L V8 applications like 550i, 650i, 750i, X5 50i, and X6 50i. It is not an E46 part, so I would ignore the chassis tag here and buy strictly by engine and original turbo part number. If your car is an N63 and the listed 793647 reference matches what came off the car, this is the kind of replacement you look at when the factory unit is worn out or you want a modest step up from stock-style hardware.

I would pick this over a basic stock replacement if you specifically want a billet compressor wheel and are already in there doing the labor. I would not buy it just because the price looks good without verifying left versus right bank fitment, oil and coolant line compatibility, and actuator setup. On N63 cars, turbo access is enough of a job that getting the exact match right matters more than gambling on a maybe-fit listing. Check the original turbo tag, compare the casting and connection points, and make sure your chassis actually uses this MGT2256S variant before ordering.
