Installing an OM602 or OM603 into a W114 Coupe bay?
Installing an OM602 or OM603 into a W114 Coupe bay?
I have a dead W114 250CE coupe. It has an OM616 engine in it, unknown if working or not.
I would like to turn this into a daily use commuter, running about 100 miles every day. Fuel consumption is a huge concern. I was thinking of installing a newer, 1980s OM602 N/A 2.5l engine from the 190D into this.
Is this possible? Has anyone done it? Would it fit straight onto the current Auto Gearbox or would I need to graft in the 190 G/b as well? Would the normally aspirated, 3.0l OM603 6 cylinder work as well? I beleive this engine bay doesnt have reinforcement struts unlike the later ones, because the W114 was meant to carry the longer 6 cylinder petrol blocks.
Any help or pointers would be welcome. I am located in the UK.

A w201. So it's possible.

A new plan is on; how about an OM605 from a C250 Turbo Diesel? I am looking at installing it in company of a C250's own Manual gearbox.
The W114 contains an auto system on it, at this time, so I might need to source a manual W114 pedal set.
Need to go read up on the OM605, it has been offered to me as a more capable engine for modern fast road use, good economy ,etc.

09-07-2011, 10:20 PM #5Any progress on this? Seems like a great project, just have to see if the footprint of the 606 isn't too far off from the M110, Just from a cursory search, it seems that tranny tunnel space is an issue, so the later and abundant 717.4XX trannys may be out. Love to hear more....A W114 with a more modern and efficient diesel, Great Combo! Now, will a 606 fit....
That W114 was inspected and found beyond economic repair. Now have a 1969 W114 which is in the que for an OM605.960 + 5 sp g/b. Unfortunately being delayed by my other W208 OM606 conversion in progress....I will update soonest.

I definitely want to see more on both of those projects. How far along is the OM606 conversion?

The W114 has a nice big engine bay and the front end is the same as the W107 SL/SLC 's .
V8 Mercs have been slotted into them for years .
The tunnel is big enough for any trans up to the last of the 722's used in the W124 .
The diff can be upgraded by bolting in a Unit from something like a Series 1 W126 500SE/SEL/SEC .
On the peachparts forum a guy has installed a OM617 into a W107 SL so there is a good place to look for hints on installing a 60x series engine.
The biggest issue would be finding a W114 in the Uk without rust wouldn't it?

the vehicle and OM605 plus the gearbox have been source. But the tech who is installing it is building me a 6 cyl (606?) Turbo diesel w208 CLK Cabrio right now. He should BE approaching this job in a few months.
Will keep you up to date. You are right re RUST. the first one shown above was shot to pieces. I have sourced a reasonable W114 for this project, It looks to have been returned and sprayed in a Rolls Royce Blue and cartel leather interior....very niiiiiice!!

Still waiting, and things arent moving any further forward.
Big ask; can anyone recommend someone who can install an OM602 and manual gearbox into my W114? Completely bogged down with the W208 build now.
Yes, the red one was absolutely shot apparently, it was sold off to Rob Parker for breaking.

The crossmember needs modifying, its height reducing by cutting out the section under the oil-pan, which needs closing up with fabricated sections. There's a specific oil-pan/lower crankcase thats needed, but cant remember which one.
Cant tell you much more, but google W114/5 OM.602/3/5/6 some interesing stuff on youtube etc...
As I say--Not straightforward, and not something I would trust to any old guy...
--Way too many issues someone less caring could really stuff up, leaving you with a pile of scrap!
--If you not interested in speed, maybe a om.615/6 be an easier option for economy....

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

I do about 500 miles a week for work and it translates to quite a bit of funds. I decided on W114 om602/5 as a nice way to travel.
The.mech who was working in the cars has given himself a health scare. He can no longer to the W114 but plans to complete the CLK as its just the programming that he is battling with.
Alistair, would you know anyone mad enough who might take on the W114 job? If not how about a diesel conversion in a W123 ce? I have followed your threads on other fora and you seem to have an interest in the W123 to know "stuff"!!

05-07-2013, 11:36 AM #15The OM616 has been mentioned a few times. Problem is that a lot of people also say that it is not very economical?

They fit so well into those engine bays
-1982 300D Turbo, 280k miles, ALDA apparently maxxed, fram 8038, 12 lbs boost, non-egr manifolds, W/M injection, 4 brake light mod, Gen II w126 front rotors/calipers, 4-speed swap
In the works: A/W IC, adjust pump, turbo rebuild (w/60 trim comp wheel)
-1980 300SD, 110k, project car. Goal is to get it lookin' like it did on the showroom floor (body and interior wise, not necessarily under the hood )
-1974 240D, FRESH PAINT!!!!!!

WILLBEHERE4U, I have spoken to the original installer choice, and he is sure that the 280CE mounts will NOT fit an OM603. He advices that new mounts will have to be fabricated.
As much as the superturbo diesel project goes, I do not intend anything further than mild tuning. This is going to be an exercise in longivity/endurance than sheer power. I am going to be using the car as a daily driver doing 500, possibly 700 miles a week! (apr 30,000 an year).
Guys, can I first thank you from the bottom of my heart for all the info, and could I ask for any further links or info in installing any of these engines.
As I said, my current top choice of installer has had to back out. I have another very capable fabricator but he is internet and Mercedes unaware. IF I give him enough information re installation and get him all the parts, he will fabricate mounts and locate all the bits easily, otherwise, this project goes boopsy.
Warmest Regards

A om603 projects started and crashed again.
The w114 280 was deemed too rusted
A w114 250ce is being repaired and we are now having nerves about the manifold and turbo interfering with the steering shaft as it's a RHD.

04-27-2018, 03:07 PM #23Just an update, the w208 project crashed and burnt. The engine failed after 2k miles. To add, the insurance was a minimum 2k for 5000 miles. I just called it a day and handed it over for pittance as spares
