606 does have the rectangular ports I thought, the 603 has round which matches up to the m103

Sbc swap in any (at least up to w210) Mercedes is a problem because of the front sump and rear steer issue. Modifiing the pan is easy enough but that doesn't move the oil pump. I've seen drag links cut and made to pass under but I don't particularly like that option. Maybe a drysump sytem would be the right move. Although expensive it also deals with pressure loss in corners. Plus you'll spend a decent chunk adapting a good manual to a mercedes motor. A ls or truck engine could be done. A Canton or similar s13 style swap pan will get you front sump but you may still have to weld on it to adjust the rear corners of the sump. I've actually bought a ls oilpan gasket to see if a m117 pan could be adapted to a LS motor and it looks possible but hard to say for sure without an actual engine to check for balancer and trans clearance issues. For the diff I'm not certain but I know the gen2 w126 and gen2 r107 are similar looking to a w124. A w140 diff may be the same mounting points too. I'll have to crawl around under some of my parts cars to look. Either way they are all low numerical ratios. 2.47, maybe a 2.8x I think for 210mm rears. I have a r129 parts car that will be on the chopping block after I get the m119 out. That rear will fit I'm pretty sure but it's 2.xx I'm sure. If you do go with a w124 I'd sell the whole r129 roller pretty cheap and you get all the heavy duty suspension and brakes.

You can get a reverse sump pan, if you raise the right hand side of the motor up enough it will clear the pivot arm. No steering or cross member modifications need to be done.

On which engine?

Did you already found out something about increasing the steering radius?
I've been searching too but didn't find much.

Im not sure about w124 spindles(or knuckles) but r107 have a bolt on steering arm that can be modified or replaces with custom a custom part easily. w201 sway bar is narrower i know and may get you a little room for inner tire clearance if it will fit.

With that you can either modify an oem flywheel to bolt to the flex plate, machine a steel round to convert the flex plate to a flywheel, or have a sexy custom flywheel made for $$$$. Then you need to decide where the starter goes.

DieselpumpUK makes some OM606 adapters and clutches to BMW ZF Gearboxes that would work. The Adapter's not awful in price but if you're not that great a fabricator or you wanna keep an OM6xx/M10x power, it is an option.

I was pretty familiar with the company that made the OM617/Toyota R series adapters. I was talking to them when they were trying to make an OM603/Toyota R series adapter using a custom cast bellhousing instead of the 617's adapter plate, but by that point the company had unfortunately folded.

I don't know what your power goal is but for that amount of work you can do some light modification to get an S13 diff in there and that gets you your 3.54-4.30 ratios. That does have a power limit that most of your engine options discuss will hit, but I'm not sure I'd lean much harder even on a 210mm MBz diff because by that point you'll be breaking output shafts at the hubs.

So does the W201 and W124.

A narrower front bar wont help your steering angle you'll hit the inside of the bar before it makes it to the sway bar mount.
