E500 engine swap project
I'm thinking now this is an opportunity to do some kind of project instead of just throwing in another box. I did some research online and found some m120 motors and thought it would be an interesting project. i found the 5.8 na v12 from the s600 too and they both sound glorious with an exhaust but to be honest i have NO idea on how it would come together, what ecu programming would be involved or how it would bolt on and theres simply not enough info on the net for me to actually decide to undertake something like this on.
Another more straight forward idea was to get an m113k and drop that in which would bolt on immediately at least. checked prices and theyre not cheap and i have no idea if i would need a complete engine with harness or if the e500s ecu can be reprogrammed, if the driveshaft and diff need to be replaced too and what not.
anyways i was just looking for advice on what to do and some opinions from the experts here who do alot of mods and custom work.
basically, what is the cheapest way to drop an m113k in and how cheap could i actually do this.
oh and incase you all forgot im in australia
sorry i dropped that one late i know it makes things 1000x harder and alot more expensive but i feel like finally this is an oportunity for me to do a project. any help is appreciated

By the way it already has the E55 bodykit and the E55 suspension isnt exactly good
My E55 in the second setting still feels like a boat. maybe because i came from a coilover'd E46 m3 but yeh this car is no autocross vehicle

It's beyond ridiculous. I know our minimum wage is more than the US but people don't earn 3x as much as the US here. They do earn more but only maybe 20-30% and don't forget it's expensive as hell to live in Australia. The upside I found to that is that when you go overseas you enjoy it so much because everything is so damn cheap 
Yh I get it trust me I do but even for a gearbox that has done 40k miles the cost is $3500. I've looked everywhere local and national and that's the cheapest I've found for a warranty'd (6 months) gearbox. I was thinking if I can sell the engine here in OZ for like $2500-3000 (which it can sell for here) I can maybe import an engine from the US along with a box and just swap out the drivetrain for a better one. I know it sounds ambitious and too optimistic but it would be cool for me if it worked. I'll deal the brakes and what not later. For me the drivetrain is my aim now. So let's say I get $2500 from the engine and then add the $3500 I would have to pay for the box, that adds up to 6k. Now I'm not trying to do anything on a budget but you're right I don't want to pay too much if I don't have to. Now at $6k lets add another $2-3k I'm willing to throw in that's around 9k and when I look at it like that it would be pretty cool if I could do it within a 9k budget. Again though I'm still researching and will be contacting speeddriven today.

Went back there again in 2011 when the AU dollar was stronger than the USD and about went broke. Spent $50 on my first lunch!
Food prices are ridiculous... but the beer is good.

HAHA everything is really expensive here and more so now because of the Aussie dollar's ratio with the USD. Last year it was STRONGER so you can imagine what it's like for tourists. Australia to be honest is kind of socialist in alot of ways. I know Americans always say at least we have free healthcare but honestly if you want real health care here you still need private insurance. Public health is pretty bad here and they almost abolished it but here we have a billion different taxes on literally everything. I always follow US politics and the whole tax talk and I'm surprised because you guys have really low taxes compared to here. Registration here costs ~$1200 a year per car WITHOUT comprehensive or third party insurance. It would be alright if the roads were smooth and pothole free but most roads are SHOCKING. You can forget about driving a lowered car in some areas and even rich areas. Anyways I'm not ranting this is a good country I'm happy here and at least it's fairly safe and peaceful. Life isn't bad here, could be better under better management and different politics but still a pretty damn good place to live

It just doesn't suit the car. I certainly wouldn't want it like that and if I do it to sell it as a unique car to someone I'm not sure who would be interested. You're right about them making huge power for cheap though. If this was an E39 BMW I'd be all over this. I've been doing some research on M113ks from the US and the shipping and tax costs.......I've realized costs mount up really fast
Another issue is I'm kind of bored of the W211, I'm gonna put the E55 for sale and maybe look into getting a CLS or a W212 E63 so I don't wanna go too custom with the E500 that's why the M113k popped into my head as it would bolt on directly, mechanically anyway.I did find a 5.8 V12 from the S600 and his price isn't too bad and he's local, I also found some M120 6.0 motors here in Aus for a good price and they're a great engine, they have a unique sound and their power isn't bad. Now that for me would be a nice project but anyone have any idea what it would take to bolt one on and what kind of electronic changes would need to be made? This is something I've always daydreamed about, I just love those V12s

More specifically, is it possible to have an entire E55 engine/drivetrain/etc. transplanted on a standard W211 chassis?
I considered it was better to ask here about the differences between the regular W211 and the AMG chassis, rather than opening a new thread.
From what I know and what @need4spd said, there shouldn't be any difference, but it is better to ask.
The reason why I ask is that I had found a complete E55 that is written off and transplanting it on an E200 is quite tempting.
I would do it though if you have a donor car.
Buying an E55 is suicidal here. I would have to pay 5439euros in "luxury tax", 3900€ registration tax and about 2000€/year local taxes. Forgot about the insurance, which would be ~2500€/year.
This is why registering it as an E200 is actually the only sane method to have an E55.
Thank you very much for your reply. I will talk with Shardul about this and if I will proceed with this "project" I will let you know.
