I have had this idea for quite a while now and can't get it out of my head. Theoratically could the M157 Turbo Setup fit an M113/M113K, as based on all the pictures I've seen trying to compare the head bolt pattern, the exhaust tubing sizes, engine bay space, etc... it seems to be a direct bolt on. Bolt pattern to the engine seems to be the exact same in addition to the exhaust tubing which looks to be identical in size and for space it looks like it can fit. The only thing that needs to be custom made are the intake pipes. To be clear I know programming the cars ecu would be hard but what I am trying to say is would it actually be a direct bolt on? or am I just not seeing something.

There were a few turbo kits for the 113k produced aftermarket, but not much need for them because it’s already supercharged and almost 20 years old now. I have a few turbo cars and a few positive displacement blower cars, and I can say that the blower cars are more satisfying to drive on the street. The guys who go to the turbo E63 w212 cars seem to miss the immediate response, and I would agree.

The m113k doesn’t seem to be as strong as the newer engines when pushed, and it’s old now. You’re really missing the small problem of intake and exhaust cams in the wrong position as well as the valves.

lol not even close to being a bolt on and nothing is the same bolt pattern between the two

i don’t know how you made your comparisons but it’s not even close

Just custom make them. The m157 factory turbos and manifolds are pure garbage.

Not saying they wont make power just saying they are a ****house design.


And if you want to see how to do it properly (forget about your E class) look here:

Actually it's great that you mention that as I do remember reading about this in a different thread regarding another turbo attempt where it was mentioned that the M113 5.0 cams and M113 5.4 cams are more suitable for Turbo applications over the M113K 5.4 cams.

Well I clearly stated that I used pictures to compare the bolt pattern (which I won't lie is a terrible idea to be honest) and that it looked to be the same in terms of tubing size and head bolt pattern but I do appreciate you're input as it is very useful and valuable so thank you for sharing your expertise I really appreciate it!

Well the reason I wanted to try and source the turbo kit from the M157 is because it is relatively cheap to find in the scrap yard and would make it much easier to install not to mention how much harder and more expensive it would be to custom make a turbo kit but it seems like it won't work anyways so Thank You for you're help and knowledge I really appreciate it!

Any details on this guy's manual transmission swap? And the build in general? Is this you??

I don't have an IG account.

Its not me.

Its a tremec magnum with custom CNC bellhousing to suit m113k. In a CLK I believe. This guy is going for top speed records in the UK hence the serious build.

There's this guy that has 3-4 videos on a manual trans conversion. Uses a trans from a Nissan. https://www.youtube.com/c/SK8215/videos

Unless you have the skill level to fabricate parts, cheaply available parts not going to help you much. No matter how you look at it, it would still end up costing you at least $15-20,000 if not more to sort out the problems etc.
So my question to you is, you got the MONEY!

The 350z trans is deff the cheaper and possibly even better option as by all accounts its probably about the same strength wise and seems to have a good selection of shifters etc.

They make some nice looking parts for the 350z conversion. The crank adapter has a lot of machined holes, I hope it is strong enough.

I never understood why they built a clutch pedal, when there's an oem one from the W211.

Here in Germany we have a few guys now, that have swapped in the 7G MCT into cars with the M113k.

I think it would technically be possible to swap in the M157 into the W211 along with the MCT. That's definitely something I'd try, if I'd won the lottery lol.

Correct I have the oem pedal set sitting in my closet. They are not easy to get though most MB parts guys wont have a clue. I got this one off Alex.

As you say the m157 into w211 is only for those with deep pockets. the OEM m157 is a POS imo. The 4.0 biturbo is a far better engine in stock trim. BUT if you build the m157 as GAD has shown when they swapped them into C classes with 1400+hp you can do some amazing stuff with them. I couldnt see the point in the m157 swap unless you were able to take the entire 4wd system and get it to work aswell like GAD did in the C classes they did that conversion too.

A 1000hp+ supercharged m113k E55 is just as doable and would be way cheaper than getting that m157 conversion right.

But imagine popping the W211 hood and seeing an oem stock looking M157.
