Mercedes-Benz in GP Turbos' listings

Mercedes-Benz had its own section in the GP Turbos shop by late 2020, and most of what it listed was diesel:

  • A hybrid for the 3.0 V6 diesel in C-Class, E-Class, M-Class, CLS 320 and CLK 320 models, made to order. It paired an oversized extended-tip billet compressor wheel with a compressor housing machined, profiled and polished to suit, an uprated 360° thrust kit and twin step-gapped piston rings on the shaft.
  • A second hybrid listed for the W212 E 350 CDI.
  • Reconditioned standard turbos for the OM628 4.0 diesel and for the bi-turbo OM651 in the Sprinter.

The old listings quoted outputs that are not repeated here, because what any hybrid delivers depends on supporting modifications and a calibration matched to it. Treat the listings as history and ask what can be built for your engine now.

AMG engines

The Mercedes-AMG engines are not covered by the listings above, so start with the part numbers on the turbos and ask. Whether a rebuild or a hybrid makes sense depends on the condition of the originals, which can only be judged once they are stripped. The 4.0 V8 is shared with Aston Martin.

GP Turbos is independent of Mercedes-Benz and Mercedes-AMG. Model names are used only to identify which cars a turbo fits.

Engines

Mercedes-Benz engines and their turbos

OM642 3.0 V6 diesel

Mercedes-Benz's 3.0 V6 diesel uses variable-nozzle Garrett turbos, among them the GT2056VK, GTB2060VKLR and GTB2260VKLR. GP Turbos' hybrid for it was built on the original Garrett, with the parts inside upgraded.

  • Oversized extended-tip billet compressor wheel
  • Compressor housing machined, profiled and polished to suit
  • Uprated 360° thrust kit
  • Twin step-gapped piston rings on the shaft

OM651 four-cylinder diesel

Used in the Sprinter among other models. The 163, 170 and 204 PS versions use a two-stage bi-turbo arrangement; lower outputs have a single turbo. GP Turbos listed reconditioned bi-turbo units for the Sprinter.

  • Reconditioned units cleaned and overhauled to the original specification

M177 4.0 V8 (Mercedes-AMG)

Two BorgWarner turbos sit inside the vee, a layout known as hot-V. The C 63 and GLC 63 use single-scroll turbos; the E 63 and S 63 use twin-scroll units. Aston Martin uses the same engine.

Aston Martin V8

M133 and M139 2.0 (A 45)

The 2013–2019 A 45, CLA 45 and GLA 45 use the M133 with a single twin-scroll turbo. The later A 45 S, CLA 45 S and GLA 45 S use the M139, whose twin-scroll turbo runs on roller bearings.

Questions

Mercedes-Benz turbo questions

Does the OM642's turbo have variable vanes?

Yes. Its Garrett turbos use a variable nozzle: a ring of vanes that changes how exhaust gas reaches the turbine. MAHLE notes that carbon build-up can jam these vanes and that oil leaks can coke them. Sticking vanes typically show up as boost faults and lost power. The sticking turbo vanes guide explains more.

What should I send about AMG turbos?

The part numbers from the turbos, the car and what has been changed on the engine. Whether a rebuild or an upgrade makes sense depends on the turbos' condition, which can only be judged once they are stripped. On the V8 both turbos sit inside the vee, so it makes sense to look at them together, and any upgrade also needs a calibration matched to it.

Does a 320 CDI hybrid fit in place of the original turbo?

A hybrid is built on the original turbo and keeps its housings, but whether anything else on the car needs changing depends on the build, so confirm that before ordering. It will only perform as intended with supporting modifications and a calibration matched to it; on an otherwise standard engine the gain is small.

Send GP Turbos your Mercedes-Benz model, engine code and turbo part number to find out what can be built.
