Mercedes OM651 twin turbo upgrade finished.

Finally finished the om651 twin turbo set upgrade. Bigger compressor wheel and free flowing turbine wheel to replace the restrictive OEM ones.

Hopefully it will reduce back pressure in the exhaust and flow more through the engine.

Looks very nice. I wish I could have these for my GLK with OM651.

@MJPilote looks great ! glad to see that the respons at low end of the turbo is way better. Thats exact the thing i am looking for. I think there is a market for turbo's like yours. You could be in the market for a lot of cars/vans as twin setup is getting a regular thing. All sprinters and vito's 2016 to 2018 have them, all vw crafters and transporters 2011 to present have them to. Golf, passat, amarok, MB E, C, you name it... There could be a business with great potential if you find the time to do so.

Great video and explanations. I am trying to figure out how to get some more power from my 2021 Sprinter with OM651 (USA version).. hope you are having good luck with your project. Any advice is greatly appreciated!

[bcored]

if you could share the dimensions and wheel part numbers that would be great

[Eliasua]

Can you please list the numbers of the original parts of turbine and compressor wheels used in this upgrade?

[ValentineFarm]

This is amazing, any part numbers and updates please?

[chipdieselperformance]

What is the max power with stock turbos?

[Jon-]

I’d love to know what turbine upgrade you used please and how much you took off

[petarbaev]

Just saved me a bad purchase. I wonder if I put a similar wheel or similar to the factory one, but with a better design of the blades and without touching anything else, will the power increase?

[dirkclaes]

If ou could be so kind making a how to and the exact part nr's, we could (let) build or turbo's ourselves. Or you could put together a kit and sell it to us. No fabs on your part involved, you still could make a profit and we would have a very badass turbo... Interested..?

Hi can you update with part numbers etc in the video description

[luisgustavoandrade]

Hey! Nice job ! I'm looking forward to adapt these turbo(s) into an old diesel engine. Since I have little or no information, do you know if it is possible to convert the original wastegates to positive pressure? Thanks for your attention ! Bye!!

[dragossoroceanu]

Hi! Is it possible to install twin turbo setup on the single turbo OM651? Do you think it is a bolt on swap? Thanks.

[WheelBuilds]

Have you tested the turbos after this work?

[nikolapatrcevic]

Is there any after action report on this? Have you tried it out? Can't seem to find the video.

[thanadon]

May i ask? When you upgrade all things of the car with this turbo and om651 engine. How much do you get about WHP after Remap(Tuning).

[marcopolo]

Can you provide turbo upgrade for sprinter 311 single turbo engine to twin turbo ?

[Dave-Huston-Dublin]

Very cool modifications, How did you balance the new turbine, Looking forward to your update.

Meikäläisel on S204 korimallin C200 OM651.913 136hp. Onko mitään vinkkejä miten tätä voisi piristellä muuta kuin perus lastutuksella?

[buildingsweatequity]

Just to confirm, did you modify your turbine housings to fit the larger wheels? Looking forward to updates.
