Hi all.

I have a question regarding something I'm viewing. The vehicle isn't an AMG, but, it does involve the M113k Motor in a way, so I figure the W211 E55 section of the forums would be a good place to ask.

It's an odd question. I'm looking at an W210 E430 with 145K miles, and it's in pretty good shape. No rust, no damages, full service history, owned by an Enthusiast, and now a collector. Here's what I had thoughts of, and I am unsure if anyone has even considered this. Say in a few years time, I decided to swap out the 4.3 M113 Motor for the 5.4 M113k, would that actually be possible? It's on my mind, since during the W210 era, AMG got the W210 Shell, and dropped the engine in there. The W210 E55, had the 5.4 M113. So my theory is...if the 5.4 M113 can go in the W210 chassis, could the M113k also go into the same chassis? This question might seem insane, but I thought it might be worth an ask, I'll answer any questions that I have a sure answer to, if need be.

Yes, it should be a direct swap. I've seen threads on the other Mercedes forum and possibly this forum as well in the w210 sections where folks discussed removing the 4.3 l engine and dropping in the m113. If I remember correctly they were indicating it was direct swap using the stock electronics in the e430 because the m113 already has the correct injectors in it. There may be some minor differences but it has been done.

If you do some searching and find the threads I am talking about, please put those links in this thread here.

I would be cautious and check the w210 forums. Surely someone knows more. I've seen a thread where someone removed the 4.3 from an E430 and used the naturally aspirated m113 from a w210 E55 and never got it working. If they couldn't make that work, i would expect trouble from the m113k as well.

I have done a 113k motor in a w203 c class before. The challenges of installing the 113k motor you will have are as follows.

1. The 113k ECU is similar to the NA 113 Ecu but has the signal to lock the supercharger clutch.
2. The 430 transmission has different gear ratios than the 113k mated transmission. There are some solutions to resolve this but will require a lot of R&D
3. Prefacelift 210 cars have the older EIS. Not sure if this will communicate to the ECU

It will be easier to get a 113 NA motor swapped and add a SC from weisman.

It should be a direct swap, its the same block, and same transmission (the 5 speed). The only issue is the driveshaft and axel, a 493hp engine might shred the axel. I'm in the middle of this swap myself but on a CLK. I would recommend getting an AMG and doing the swap on that just for the brakes, and stronger drive train components but I feel just wanting to do the swap lol

I researched this extensively a few years ago for a CLK swap. It is more or less plug and play mechanically. There is more than one way to do the electronic portion but I figured at the time that swapping ECU, loom, TCU, diff and transmission was the easiest way to get a fully functional outcome with minimal hassles. I can't remember the exact reasoning but I think the mismatch of parts would require a lot of trial and error and possibly coding. I don't know what options are available for superchargers for the N/A M113 right now but I also ruled out that option in terms of difficulty vs a full M113K swap; dealing with MAF clamps and other issues just wasn't worth it. Also the old autorotor superchargers were discontinued in favour of less effective options. Getting a full wrecked M113K car would be the most cost effective.

Sorry if any of my information is now out of date.

Thats not a bad option if you don't mind a cap around 500 to 550 hp which is where the M113K starts. You also have to consider the different compression ratios when wanting to add more boost and the age of the motor plus the stress of the new S/C. Also the price is still high unless you get a used one, but I believe VRP is working on a S/C right now that is pretty cheap compared to weistec or Kleemann.

Exactly. The kleemann one was originally a twin screw but then changed to an eaton roots which was much inferior.
