i know i'm a little late to the party.. but this is compelling.

 

hey 503 there is a portland e55 engine (which may be old news) over here

http://www.automotix.net/usedengines...8ee9&seq_num=6

when i hit the page it was engine 5

 

My friend will be taking his C43 to the dyno this Saturday, so I can report back about the A/F ratios and RWHP once we have the data

 

Is it possible that the ecu works with this swap because there were a few factory w202 55's produced?

 

Stck ecu will work fine.

 

Fresh off the dyno. (Dynojet, SAE correction applied)

309.90 torque
284.66 rwhp

Running stock C43 ecu

A/F runs rich, then levels out and only goes lean around redline.

I think there is more power to be gained if the C43 ecu can be reflashed with a E55 performance tune.

Looks like you guys had quite the crowd watching the dyno

WOW... almost 70 ft/lbs and almost 45 HP more at the rear wheel, IMPRESSIVE. More and more I am thinking about canning the W210 idea and dumping the $$$ into the 55 swap...


P.S. I found this vid:

NICE 500E

 

The numbers are good. I want to see if we can squeeze another 20-30 rwhp with a tune. Need to convince my friend its $400 well spent dollars

Group dyno event for the BMW CCA guys, so lots of people around.

I have a few vids of my cars on youtube, nothing special, mainly slideshows of pictures (which are all on my web site.)

 

Very nice #'s. That's about where mines was when we first dynoed it with the stck exh and SW.

Other than the exh mani's one of the biggest restritions with the w208 CLK55,W210 E55 and C43 is the way they designed the air intakes by the front grill. Just horrible. Very very restrictive. Find a way to get around that and you'll definitely free up some topend hp. They did it right with the N/A SL55,S55 and CL55.

 

Any suggestions? 2001 CL55 air intake?

 

It wont work. The problem is the radiator support and the small inlets they have by the front grill. SpeedyBenz and mbenzman have the best solutions. You'll have to trace their threads.

I did like Mbenzman and put in the entire CL320 intake and built a ram air intake by losing the passenger side foglight where the space is much bigger and where you'll get tons of air rammed into the intake.

 

What are your numbers now???

 

Shouldn't take much convincing, $400 for even 20 HP is WELL worth it... I would spend $800 for 20 HP RIGHT NOW!!!

 

You and I know that, but the owner is not like us. Takes a lot of pushing

 

hate to rain on your parade guys, but i looked at this thread and it hit me. I have an 03 s430 basically same engine as the c43, do you think i will be ok doing a straight swap as well, leaving ecu untuned?

 

Nice numbers....really wakes up the W202!

 

Same base engine yes, but without the AMG cams and other goodies

 

I'm curious.

Anyone know if the w211 E55 motor (M113) will fit--supercharger and all? Would it be too much power for the 722.6 trans (better question---does it have the 722.6 transmission?)?

 

I think it does, but you will need to sort out the electronic gremlins to get the thing working correctly. Concerning the transmission, I can't say but others more in the know will certainly chime in soon

 

You need to see Money-One's thread:

https://mbworld.org/forums/c36-amg-c...-you-cant.html

It's doable (he's done it!), and there are probably a few other swaps out there (including at least one in Germany) but there's not a lot of info on it out there.

I recall Money-One posting about his difficulties with the engine management, and how the stock ECU is at its limits to tune the supercharged engine. The alternative is stand alone engine management, but the next issue there is that most aftermarket stand alone systems don't typically have the capability to handle twin spark heads. If the heads were normal, I suspect Money-One would have gone down that route, and happily running the car, long ago.

I'd be keen to see what the German swap(s) have done in this regard. It could potentially involve the entire drivetrain and electronics swap from a 55K car? Sounds like fun, but I'm sure its a huge pile of work too!

 

I wonder what happened to the ex-AMG technician who started to post on here some months back I'm certain he would know something as I can image that AMG special projects department (I'm sure that exists....) would have done that kind of conversion. A pity as it seems he just disappeared I hope we didn't frighten him away with all our questions

 

or got "taken care of" by the /////AMG Gestapo


By the way i bought a m113.980 (E55 W210) engine today for about 1000$... will start a project thread when i get it on friday

 

congrats buddy.
how many miles on that engine?
1000 buxx must be a high mileage engine or what?
then you need a 300 speedo

 

It has a cracked oilpan and the cabel harness has melted.
Its about 12500miles on the engine..

I am going to do a total renovation of the engine. will replace all gaskets and send the heads to the pressure test, check the crankshaft bearings, replace the water pump, etc., etc. paint engine in light gray/white as the M156 engine..

 

Nice buy. My 43 motor is coming out this weekend, should have the 55 into it the weekend after!
