Engine Swap question
Hey all,

I was wondering if this engine would fit into my 92 190e 2.6. Also how difficult would the swap be?

Very difficult and expensive---use the time to dream about an old girlfriend that got away while you were painting your calipers!

Engine Swap Question
1 Attachment(s)
Hey Kaman,

A M103, 3.0 is a direct fit into a W201 Chassis.

My son and I did exactly the same swap into a 1989 W201 2.6.

I haven't got a photo handy at the moment however we later swapped a W202
M104 C36 Engine into the same Chassis (see attached photos) with no fitting

The only difference in the fittment was the need to remove the oil breather crossover pipe for hood clearance.

We also made up our own ITB set up which really turned that engine into a monster!

As you know, the W201 2.6 has the removable top radiator support which once removed gives you easy access to the engine bay.

If you decide to do the 2.6/3.0 swap you will notice a difference in power and consider also adding the ITB's which will give you a lot of extra go.

At the moment we are just starting our next W201 2.6 Engine swap conversion.

We are swapping the 2.6 for a W203, M112k Engine and Transmission from a C32 AMG (see attached photos).

The car will be an EVO 1 clone when complete with a little extra punch from the M112k Engine and Transmission complete with combined Touch Shift and Paddle Shift.

The Diff is being swapped for a Wavetrac LSD and the Tailshaft will be from a C32.

TA Coilover suspension has been ordered and the Brake Calipers are from a W163 ML500 with 340mm two piece disks.

The Wheels are original brand new "Old Stock" EVO 2's, 17 X 8.25 and the EVO 1 Carbon Fiber Body Kit, which arrived a few hours ago, was made by Hedehog Tuning and Motorsport. You can see the body kit at hedgehog-tuning.com website.

Apologies for hijacking your thread but I was just about to post the info anyway.

Good luck with the swap

(Lost pict 11 ???) Pict 13.

BTW, You may have noticed the Sump and Exhaust Manifold are not the standard kit found on the C32, M112k Engine.

Both the Sump and Exhaust are off a W208, CLK320.

The CLK Sump allows clearance of the W201 Cross Member and the CLK Exhaust "Wraps Around" the Bell housing and allows for clearance of the stock W201 Steering Box.

Pict 14.

The M112k Engine's Sump is a two piece unit with oil "storage" both front and rear.

The C32 Cross Member sits between the two sections and the Oil Pump has two pickups, therefore the Pump is swapped as well.

The Pump we used is from a 2002 ML320.

The original M112k Pump pumps more oil than a standard M112 C320 unit so therefore you need to increase oil flow from the 320 pump.

You can see in the next Picts we put a extra hole in the stock oil pickup.

The M112k Pump drive sprocket is larger than the stock M112 sprocket (by two teeth) therefore the 320 Pump drives faster.

When I tested the Oil flow of each unit I found the difference to be negligible.

Last pict.

Hope you found this info of some interest and when we complete the build I'll post the progress.

Definitely the las one!

I had a few components Ceramic coated for a bit of bling!

kmancoupe230 09-19-2017 06:52 AM

wow great builds, those things are sleepers!

Would you say the M103 3.0 is a 100% direct fit with the electronics, the mounts etc? I had bent the valves on the original engine that i have and was just thinking of replacing out the whole thing with this motors only if it was a "plug and play" type of swap.

cracklin 09-19-2017 07:50 PM

The Engine will slip right in, it's a direct fit.

The only Electronics that might be different is the EZL Ignition Module.

The part # on the 2.6 is. 008 545 61 32.

This EZL is used on W201 / 124 /126. I'm sure it will work on the 3.0, I just can't remember what I used. They are on EBay for around $40.00.

Engine Mounts are the same and of course your 2.6 Tranny will bolt directly on.

When you have the new Engine be sure to check and change if necessary, the front and rear engine seals (cheap and easy job) and the Water Pump---a lot easier to change with the engine out.

All the Engine ancillaries including the water pump are a direct swap..

kmancoupe230 09-21-2017 11:01 PM

How difficult is it to pull the engine and transmission i.e. hours and tools. i have a pretty handy toolset with over 200 pieces (sockets, adapters power tools etc)?

cracklin 09-23-2017 02:22 AM

I've tried twice now to send you detailed instructions on the engine removal and each time I hit the "submit" button I get asked to log in again and once I do , my reply is wiped and the site wants me to go round in circles!!!!!!!

I'll have to walk away from it for a while otherwise I end up throwing the frigging computer against the wall!!!!

kmancoupe230 09-23-2017 08:20 AM

Would you be able to pm? I'll try to post for you I'll.do the removal today with a friend
