Yes it would work, but goodluck finding one. The C36 engine is another common transplant.

4K for an engine from a car that is worth 5-7k? not too realistic.

Any engine swap is not going to be less than 3-4k if it's not the original engine...

I like the car and I don't feel like I could get anything nearly as nice for the 4-5k the engine swap would cost, so yes, it is quite realistic.

Umm, I got a 1990 300ce for 2500 here in l.a so the cost of an engine swap is not really realistic IMO...

I mean sure, the engine is twice the cost of what the car is worth, but what car would you get for the cost of the engine swap? Over here I'd be lucky to get a 99 Taurus with 120k miles so I'd rather take the C36 engine and put it in my CE and have a really nice car that can move. It really is about what makes you happy.

V8 transplant is very difficult (other engine bay, other gearbox bay in V8 models!)

easier is a installation of a c36 engine - but there you have the difficulties with the ecu etc.

you can also use the c36 engine with the m103 head .
with the right setup you have a 250hp, nearly 400Nm engine.

I wouldn't even recommend it if he had a regular 300ce, but his looks like this, minus the wide fenders, so its pretty unique and rare:

1992 300CE AMG Hammer
500E Engine in 1992 AMG 300CE W124

hello guys

i just joined this club today cos i am desperatly looking for a solution to upgrade my '92 300CE that i love so damn much....

it currently runs a 3.2 24V engine - like the power in it.. but want more.

so will a 500E engine fit? will it entail new comptaible transmission as well? i'd appreciate your thoughts.

I am also looking for spoilers to give the car a new aggressive look. can anybody tell me where to find the front bumper spoiler on which i can install fog lights (rounded or rectangular will be just fine).

i got many more.. but i'll leave it at this for now...

Swapping in a 500E motor would be possible but not cost effective.

Theres a thread somewhere where a guy scrapped the v12 in an R129 SL and swapped in a chevy motor for less money than the routine maintenance on his v12.

If you want cheap performance that is probably a better alternative. Even swapping out to another stock mercedes motor is going to cost you an arm and a leg, and probably wouldn't be any less difficult than switching to a different motor. You pay quite a premium for the smoothness and incredible build quality.

You'd have to really know what youre doing, the guy that did it to the SL knew exactly what to do, how to do it, and it wasn't his first rodeo.

Isn't the cross member under the motor different for the 400/500e, and I've heard that the transmission tunnel might be very slightly enlarged?

I think swapping in any type of v8 is going to be very difficult. If -I- were going to do it, I would do a -lot- more research and I imagine would try very hard to go with an chevy lsx derivitive. I've swapped motors on older cars before, but the magnitude of an engine swap on a w124 is mind boggling to me right now.

The C36 motor seems to be almost a bolt in, thats probably your best bet... but for that, swapping a whole motor just to get 250 whp seems kinda crazy to me. A 500E has got to have close to that power out-of-the-box, why not just buy one of those?

I'll PM you the link the the thread on swapping the lsx into the r129.

Yes, you could do it. Someone from YouTube did it. They transplanted the 500E engine into the 300CE they had. I've personally never done it, but i've seen some people do it. It's very possible.

That person youre talking about on youtube is Roman. The same guy with the 650hp turbo 300e.

Search 500CE on youtube.

You need the WHOLE front end of a 400E or 500E to make the engine fit. Do an LS1, supra motor or C36 instead...

Anything will fit with enough money and/or skill.

You will need custom exhaust to clear everything, and probably need to fab up some motor mounts.

You will need to steal the transmission from the car the motor comes with, as well as the computer. This leads to custom driveshaft and transmission mounts, and your rear end will not handle any decent amount of power...

It will be exactly the same amount of custom work as swapping in an ls1 or anything else.

in order of difficulty from least to greatest:
least: find a c36 motor and swap that in
moderate: find a rearended 400/500e and swap in the front half
most: anything else, same amount of custom work for any other mercedes motor as it is for a non-mercedes motor. May as well go for the gusto and try one of those six liter twin turbo v12s or something.

Interesting, how much work does a c36 swap need?

A 500e/400e engine conversion would require extensive modifications to the secondary firewall and not worth the trouble in the end.

The short answer is yes and you can find examples if you do the research. The real question is how much is your friend willing to spend or ask him how much mechanical and electrical abilities he possess to do the work himself. There are very few shops who can do the work and very few who will spend $10-15k or more on a CE. Conversions from my experience are a personal endeavor and are not financially practical...
