Appreciate the feedback. I've looked into the motec units and even the person that I spoke with at Motec thinks that if going their route that the most likely method to retain other systems would be by piggybacking. But admittedly aren't sure if the stock systems would go haywire by trying to piggyback that way.

The most simple way that I can think of is just swapping in all the 63 electronics are necessary. I guess a simpler question would be "what necessary electronics ARE compatible between the older platform and the ECU necessary for the 63?" I thought that there might be a couple of mbenz mechanic types or performance shops who have seen older equipment along with 63 equipment and know what has actually changed along the way....

It seems that I may need to go more grassroots and hunt em down the old-school way of phones.

I was just browsing some UK SLK forums and there were threads about the SLK with the 6.2 motor. A lot of speculation about the chassis with this motor and whether MB will soon produce one with the 6.2, etc.. (speculation that went back as far as 2006.) Lots of people saying the bonnet and bay has to be enlarged; the weight of the motor up front means redesigning the suspension; the chassis dynamics won't ever work with it; etc., etc.. blah, blah.

Anyway, despite whether or not it's a good idea or not to drop a 63 motor in an existing SLK chassis, most people here aren't that curious about nor understand it (as Marcus implies.) Nobody here will (or can) answer the question other than in some rhetorical fashion. OP needs to either do it or don't do it. Whether it's worth it or not in time and money is up to him.

Seriously, I can get into some trouble over this, but I will try to give you guys some good information.

The SLK 55 AMG is planned to continue with the 5.5 naturally-aspirated engine. A lot of the reason behind this is fuel delivery system since the new 63 AMG uses tandem fuel pumps and filters and there is just not enough space under the R171 SLK for this setup.

Things could change, but this is unlikely.

....now run along little boy and go get your shine box....

You're proving yourself to be blind to how cars or modification work over the marketing of a large manufacturer. I never asked if a 63 was going to be OEM nor do I care since I doubt they ever would for any significant production run. This is the same situation as to why people are wondering why the Porsche Caymen doesn't get the turbo motor--IT'S MARKETING AND PRODUCT POSITIONING.

The SLR/SLK motorswap is a prime example of where fuel pumps had to be upgraded. So are the numerous slk55 motors where people bolted on superchargers with and without fuel upgrades.

I'm quite certain that you know a good amount about OEM mercedes everything, so I'm not even going to comment about that. But do the world a favor and learn a little something about modifying cars before you start talking as if you know what it takes.

P.S., The world is round despite what you may have read somewhere.

Check out srtforum. There's a guy on there that popped a merc 5.0 in his Crossfire. He could probably tell you a lot about the electronics side. http://www.crossfireforum.org/forum/...ion-diary.html

Obviously you haven't been getting the answer you want here. Time to just close it down and either get to work on the project and let us know how it.

People here just don't know about the SLK because this isn't the SLK part of the forum. Most owners here that own E's have gone to SL's when they go 2-seater MB. Even then, they don't know the differences in the platforms. Most people that have put big $$$ into their AMG's haven't done something like what you want to do.

You asked for help and the people here are trying to help you. If you don't want it or like it, that's ok, but you should probably be thanking them for their input. Take your attitude somewhere else. Good luck, continue to ask questions and the people here will do the best they can to answer them. Please don't ridicule their answer or you're likely to receive nothing from them in the future.

Well again, the answer is how much money you want to spend. There is going to be some trial and error and I doubt that anyone is going to be able to give you a straight answer as to whether the factory Bosch ME ECU is going to be 100% compatible riding piggy back on a MoTeC system. You're going to have to invest the resources to find out. I think you are wasting your money, when the factory 55 motor could be easily modified to take sufficient HP for a street application while retaining all the factory electronics.

The ECUs are not the same... 55s use the Bosch ME2.8 and the 63s use Bosch ME9.7. Fundamentally different and likely not compatible. You may be new to the MB world and unfortunately we do not enjoy the same kind of "transparency" from Mercedes that one wishes for. We really have little to no idea even of what the differences are between the various 55 platforms and their engines, so questions like the compatibility of various Bosch ECU platforms and engines is more in depth than MB or most tuners are willing to share with the community. I'll tell you something though, I'm sure we can point you to a number of shops that could pull this mod off very easily... but it'll cost you.

That's another option... sorry we couldn't be of more help.

That could be very helpful. Would have been nice to see the SRT (shares a lot with the SLK32) converted, but I'm sure there are some things the OP can use.

azncarjunkie

Esh, i have no issues with other people chiming in about how it's not economical nor easy, which I'd imagine it wouldn't be. C43 chiming in that it's a fact that it's "impossible because he says so" is just plain bad for the progression of any internet community that does want to learn more about their vehicles.

Marcus, thanks for the insight as I'm sure that whoever reads that will have actually learned something useful.

Most projects are for the fun of doing so and learning rather than just the end result.

azncarjunkie

I saw the guy with that crossfire post somewhere. My understanding is that the crossfire is the exact same chassis as the old SLk (r170). Chrysler saw a good platform and just used it on that. I believe the 300M is an E-class chassis also. Probably why both of those cars actually got good reviews from auto critics.

Also why it's easier to swap in the 55 motor since electronics like eachother already.

thanks for that thread link. didn't see the actual thread build before.

220S

C43AMG, don't forget that part of the deal with the AMG PL is to never link or copy/paste anything that comes from there. That's part of the user's agreement, fwiw. They claim that they'll close down the Q+A sessions if it happens. No biggie, just a reminder.

p.s, I realize it was a while ago and Rob Allan is now with Maserati, but just the same...

Esh

Understandable, looking forward to updates.

I have a Bosch inline pump sitting in front of me on my desk that will flow enough fuel to supply just about anything. Certainly it's not a practical solution for mass-production, but for an engine swap it would work just fine. Maybe you're forgetting that this is a DIY project, and not a production-ready car that has to pass numerous tests(EPA, NVH, etc..), easy to manufacture, be OEM in every way, hit a certain price point, etc.. According to you, if AMG/Affalterbach didn't do it, then it can't be done. By anyone. Ever. All because some guy said there's two fuel pumps. The fuel pump issue is not really even an issue compared to other elements of a swap like this. I'm not sure why you're hanging onto it so tightly???

C43AMG

It all started with his first post where he thought it was a simple "plug n' play" dropping the 6.3 into the SLK55 chasis.He said "I'm assuming it should physically fit easily since a 55 motor will fit and it's likely the same mounting points." My response of "It doesn't , it won't and if it did, Afalterbach would have." was answers to - "It should phsically fit" , "easily" and if boths of his points were correct ,then Affalterbach would have dropped it in and we would have the SLK63.The sarcastic comments start on posts # 8,10,17.The discussion started with "fitment" and then proceeded to a DIY.I then posted the proof that it wouldn't work - as a "plug n' play" and this is where we are.

itsmeek

I'm a little confused here- what is the difficulty in adding another inline fuel pump? We do it in DSM's all the time- it's actually a very simple thing to do w/a proper fpr. Which engine swap is plug and play?

azncarjunkie

Plug n' play is where YOU are, I don't think anyone else is there.

Re-read the first post. Nowhere did I say that it was a simple plug and play, nor would I make that assumption. My primary area of concern was the electronics since I know that the systems all work together and the 63 electronics were different than the older systems (as Marcus more clearly enlightened us).

Additionally, "fitting" the motor does seem like a very likely candidate that would "drop-in" with very little or possibly even no modification to mounting points. It's still possible that engine dimensions/angles/etc will make it not fit in the slk, but I haven't heard anyone say exactly why yet.

If Brabus thought the way that you did, Brabus wouldn't be shoving V12's into the CLS, Gwagon, Eclass, and others. Afterall, if Affalterbach didn't make a V12 CLS, then it "can't" be done.

The challenge isn't the limitation of "it can't", but "how"....regardless of effort and $. That's what I'd imagine most true car modification enthusiasts want to know and then make up their minds if it's worth doing.

We'll see how this goes. Future projects are probably going to be an American muscle followed by cramming v12's into other chassis. I'll keep people posted...will be slow progress as I get the motor built to my likings.

I say good luck with your build!

In the UK there isn't much call for transplants and when I did mine I had a hell of a time getting information to do a relatively simple swap of my 430 engine to a N/A 55 AMG. Even Mercedes UK were telling me it couldn't be done! .

If you've got the funding as Marcus says anything can be done. You may not have got your answers here but keep looking.

Here's something for motivation: http://www.youtube.com/watch?v=L5MA0svuuE4 .

Yeah, I guess if that weren't the case then AMG would have never existed in the first place. Aufrecht and Melcher would have given up from the very beginning.

Hotrod-Realtor

One of my first hotrods was a 1975 Chevy Luv. (that was a little japanese built pickup from Isuzu with a bowtie on the grill) Someone had shoe horned a small block Chevy into it and I added a blower. I also had a 1978 Trans Am with a 6.6 with NOS and a Doug Nash 5 speed along with others. I understand the lure of doing something out of the ordinary but over the years have learned that buying the latest and greatest technology is an easier and less costly way to make you grin.
I'm curious what your projected budget is for this endeavor. Add that to the cost or better yet, current value of the car and engine to get a total projected investment. If you took those same dollars and bought a (insert what that money would buy) it may be more fun to drive, pleasant experience with fewer breakdowns, issues and more importantly a better re-sale and investment. Just my .02
If you decide to take on the project I wish you the very best.

azncarjunkie

Definitely appreciate the insight as in my head, i certainly 'know' the same thing, but I'd probably imagine that despite the headaches, trials, and tribulations, that you wouldn't trade in the experience and fun of tweaking and what you've learned along the way.

The budget is for fun. I'm already assuming that there will virtually little to no resale value (including if the car catches fire and burns...otherwise the motor should still be something).

I've got other vehicles for reliability. Something like this is much more for 'fun'. It's like a grown up's soap-box car

citylightva

I don't know how much you read thru that Crossfire thread, but I think the guy in France was transplanting the 5.5 into an SLK...I know that's totally different, but some of the ECU reporgramming tips those guys have are probably pretty useful to anything you are trying to do. Like they said though, you really want to find a Star Tech and pick their brain....

Roupin

Prove? If you like it, go for it
I've seen it enough times with dismal results. Everyone would swap out the 4L60 for the 4L80 and get less rwhp.

NORCAL///AMG

Hey Azn,

Sorry, no insight to lend but good luck with the build . Keep us posted...also, there is no feeling quite like building something that no one else has. If you build it...they will come
