Mercedes 5.0 in a W124
Anyone know if it is possible to swap a SL500 egine( or any other series 5.0 or larger) into a 1992 400E? Wondering if the M119 4.2 tranny olts up and what wiring/electrical mods must be done. Any info helps, thanks.

1992 400E
I was reading more on this and found on one site that the block (sl500) has different mounting locations and the electronic/ecu differences make this swap a real pain in the ****
From what I have read it is the same exact block. I can't really see them making a new cast for an engine rather than desiging around same one they have/had. Can anybody clarify this? I think if I had agood donor car with all electronics and mounts it should not be that bad. If the bore is the only difference between the 4.2 and the 5,0 has anyone ever tried to bore out the closed deck 4.2 and run the 5.0 pistons? Obviously,you would need to have the cylinders coated again, but many shops do this now for decent price. Just curious. Sorry for the long post

Yeah if you won the lottery. You could sell you 400E and for what MB would charge you for 4 pistons you could buy a 500E. Not to mention the machine work, cylinder etching (Alusil? SPECIALTY and illegal in some US states due to the chemicals), cams, crank, rods, 4 more pistons, injectors, ETA depending on ASR, LH chip, brakes, suspension, recaro seats, sport steering wheel, fancy burl wood, AWESOME fenders, huge sway bars, etc etc etc. 500E v8 is slightly different from the SL M119. Mercedes didn't spend 18 days building each car, utilizing the old porsche 959 production facility because it was basically a 400E with a few more cubes and a bumped sticker of $20,000 over the 400E. There are huge differences between the two cars. RBYCC is trying to save you a huge headache.
There are only a few years of LH SL/S500 V8s between CIS and ME1.0. The 500E only had 119.974 engines I think, some closed some open, all short deck. Long block from MB $45,000.

I told you EXACTLY the m119 v8 to look for, whats more useful than that? If you want to build a 4.2 into a 5L you will need most of those parts I listed. To get info you have to ask the right questions, and you need to do enough reading to understand the answer to those questions. Like now would be a great time to look up what a M119.974 engine is.

I like the "built, not bought" option if I didn't want to spend money on it I would have bought a Kia project car (could get more useful info probaly)... go ahead and hate! I'm not trying to build a 500E contrary to popular belief. I'm done lock it up or delete, as this is going nowhere as far as useful info... unless you need a reason to buy an 500E
"Hate"...what, why...you've got nothing to "hate" over...also indicates your level of maturity..
You get responses from those who know the costs and the problems but don't like the answers you get...
