Hi Guys,

I have had a 1999 C43 for a couple of years now and want to get a 55 engine swap done. Does anybody know of any mechanics in Southern Ontario (Canada) which can do this for me?

Thanks!

It's not challenging to say the least. Any indy mechanic who can yank out your engine can do this swap. The only thing you need to change is to add a simple water outlet on the back side of the head on the 55 engine. Buy a 55 engine with the same oil pan as your C43 and it's pretty much just labor you're paying for.

So if you already had a euro/MB mechanic you were using, that person can do this swap. That's what I did.

its still warm enough to do it yourself. buy a case of beer and invite one or two friends over that work on cars. oh dont forget to buy that water outlet.

no problem

Thanks guys...unfortunately, i cant do it myself. Don't have the know how to do something this big. Also, I went to 4 independent Mercedes mechanics and all have said that they aren't interested in trying this swap (regardless that everyone says it should be easy). So, if anyone has an independent mechanic that would be open to this, let me know.

My mechanic also had serious doubts that it would work. Just don't tell them that you're doing a swap, just tell them you're replacing the engine but you have to use this new water Outlet because the replacement engine won't have it.

yeah they wont have any idea that it is a bigger displacement, the engines are identical aside from stamping and internals. in fact... pop on that water outlet yourself if you can or tell seller to do it for you that way when it arrives its just plug and play. also dont forget to use fuel rail from the c43. you'll need the smaller injectors

Sulaco

used the E55 fuel rail on mine, though, works fine... ??

green injectors are the same between 99 C43 AMG and 2000 E55 AMG, why is C43 fuel rail and injectors preferred on engine swap and not the E55 stuff?

mickey13

idk. i guess the green ones are fine if they are off your c43 or any model. but if he ended up getting a different 55 then he might have a different color like cream ones that were on my 02 clk55. those were no good i believe because our computers wont adjust for the increased spray

KJI3jflarryfe93

cream suckaz are bigger injectors they are not perfectly compatible

ProjectC55

Your info is INcorrect. Early E55 and C43s use the same green injectors. Even the higher compression later M113 5.4l 2k+ motors with the different color injectors will work with the green injectors if installed in the C43. Motor is not the issue. Just that the later cars use a different ECU.

Will the cream coloured injectors work with the C43 ecu? The 2002 S55 Motor has the cream coloured injectors and I didn’t swap my green C43 injectors over to the 55 motor. Do I need to? Thx

ProjectC55

If its a 98 or 99 C43 you will have to use the Green injectors. A 2000 C43 Im not sure because I think that year uses a different ECU.

No bro.,

i used those (283cc) Beige injectors on my previous "98 C43", they were great,

as i know; C43 uses the same ECU, even with M/Y 2000,,

the only thing differ, that MB added "8Gn" file data to recognize the shift DAS position for fire-up, through the TCU..

Great to hear, Z! As always, I trust your knowledge immensely! I’ll give them a shot and I can always switch them out after. Thx 👍

Any Time D.,

You may forcing a little bit Engine shaking at low "RPM",

if so, have to drive the car a shot distance to let the ECU to adapt itself, with "O2 sensor" back signal & for a new "MSG/fuel angle",,

in my case; i didn't force that, just in case if that happened with you..

Duly noted, Z! Thank you!

D. 👍

Zayed which Ecu did your car have ME2.0 or ME 2.8? And doesn't the 2000 car have a different Ecu/TCU than the 98 99 cars due to using the triptronic transmission?

cm60k

Hey Carl,

I had "ME2.0", with gate shifter & tiptronic shifter as well,,

ECU & TCU are the same,

the only thing differ, between 98>>00, that MB added "8Gn" file to ECU data,,

for tiptronic shifter to recognize the shift DAS position, which doesn't matter with "MSG/fuel" angle or "E-prom" map..

Did the engine swap go ok? Did you have any problems with the ecu?
