solving the problem of the control unit, I don't think there is a better engine.

Ive seen this you have to use the om613 harness which is a little different and id rather go full 648 minus the emissions junk. I dont think an OM648 has been done into a W460/1/3 before?

and here is a 613 he put in a 460, dimensions should be similar

Baldur/knarri have done a few 613’s 648’s and 628’s into various patrols now and have been running a number of years.

Quick update on this some snags crop up with this already, one is that the airbox fouls the servo (ON RHD), the workaround on this is using a late w126 servo, or a remote servo perhaps or maybe even graft in an electric brake booster like a W211. Another is the bellhousing is so big the options for fitting in a G is limited.

To use a proper G sump you have to cut the back end of the sump off and weld on the back half of a 613/648 sump so as to retain the block pattern and also its required as the starter ring is so massive,the stock sump wouldnt clear.
Other option is to use a W210 E320 sump but offroad ability may be compromised.
W220 2 piece sump is an interesting one to look at but i have no idea how feasible this would be to even work in a G

Next issue is simple yet complex, gearboxes. I would want a 6 speed manual so for me i would have to use the auto bellhousing and a .654 strong 6 speed box and cut/weld to make this a bolt on solution rather than go with an adapter plate. However the snag here is the clutch/flywheel combo. You would ideally want dual mass for this afterall your going to the effort of fitting a super smooth quiet and efficient motor in you would want it to be as smooth as possible however theres no DMF compatible with this motor (that i know of).

If you really want to fit this engine in a G you have to either start with a LHD and keep it auto, thats the easiest solution. If manual the easiest option is go bmw box and single mass with adapter plate which there are plenty of options out there
If fitting to a RHD you have to think a bit outside the box - stick to a G wagen or similar airbox or go with a remote servo or electric booster.

Would you have enough room if you used a LHD pedal box on the RHD, it moves the servo over to other side, closer to wing. You just need to drill out a blank/hole to get it to fit and function

Using the lhd pedalbox with a 126
Servo on a rhd solved the issue with a 613, im sure it probably would with a 648 aswell but itll be very tight. Minor gripe however as that is a really easy workaround with the airbox. Im going to be using a twin diaphragm servo from a newer sprinter so that would never work for me personally. Maybe a future project when i finish my current G restoration

The adapter is for a 6 speed bmw box i believe, and its not dual mass. Theres plenty of single mass options out there.
