om601 2.3 turbodiesel power limit - SkauneJohan - 09-12-2021
like the headline, i got a w124 automatic and thinking of putting in a 2.3 turbodiesel from a vito/sprinter
I wonder what are the power limit of the om601 is for longevity (and drivetrain too for that matter, understand that the autos are durable but how about rear axle?) plans would be superpump from dieselmeken, intercooler and matching turbo (holset he221?)

This is a very interesting question. I would be happy too, if someone knows an answer.
RE: om601 2.3 turbodiesel power limit - Steve77 - 11-03-2021
Has nobody an idea?
RE: om601 2.3 turbodiesel power limit - vica153 - 11-03-2021
Finding specific details about tuning up a 601 is going to be hard. They were only used in sprinter vans, so they have a much smaller amount of modification information compared to the other diesel engines. Its a 2.3L 4cylinder version of the 603, so whatever people are getting out of a 603 you should be able to hit 65-75% of those numbers. If the 601 injection pump flows the same as the 603 pump, then I would guess a maxed out 601 pump could do maybe ~150hp.
As far as the transmission and rear end capability, if you have newer w124 that came with a M104 and 722.5 it can obviously handle +250lb-ft without issue. Depending what kind of w124 you have and what trans/diff it has the limits might be less.
Did any of the OM601 setups use an intercooler? If not, then that is the easy first step for power. As someone who has spent way too much time working on swaps, I think you should keep in mind "more simple=more driving=more fun". Put in an intercooler, crank up the stock injection pump, make sure your radiator and oil cooler are good, then just drive it.

Hum...
I have tuned a 2.3 N/A version of 601, namely the .9 for a sprinter pick up van.
Well the original pump is fitted with 5.5 elements able of about 60ml max... no way to go there. So i've build a 7mm pump based on the ford engine. It went from a sleeper to a spinning wheels in 2nd gear.
This engine has very week rods, as it evolved from the 601.1, wich is the well known 2 liter found in 190D's, So keep that in mind, nevertheless one can fit it with better rods and even the 604 head assy.
601.8 wich is the turbo 2.3 has a 6mm pump but this pump does not go over 70ml as they are not same elements as in 605's and 6's.
But all this 4 cyl pumps can be modded to have 150cc outputs...just cost money.
Anything else pm me .
Regards

The benefits of the om601 are smaller and lighter, which worked well in the van chassis. In a w124 you can easily fit an om603, that is the easy solution if you're worried about power. I don't think there is really much difference in availability/cost. If you already have the om601, then you could get it working and see if ~100-150hp is sufficient. If you end up wanting more power, then swapping in a om603 would still be the better option.
Spending a bunch modifying an om601 doesn't really make sense if you can just put in an om603 instead. A tuned up om601 might be able to make as much peak power, but it will only be up at max rpm and with the 603 using stock elements. The rest of the rpm range the 603 will make more power and be more driveable, less prone to smoking.
RE: om601 2.3 turbodiesel power limit - Petar - 11-04-2021
The 2.3 turbodiesel was never fitted in a Sprinter, only in a Vito. The sprinter got the N/A 80hp version or a turbo OM602 with direct injection and 100/120hp.
The power limit really depends on the rods. It is pretty much the 2.9L om602 or 3.5L om603 minus 1 or 2 cylinders. There were many variations in that particular size so unfortunately it is impossible to know without opening the engine.
But fit 2.9 Sprinter rods, MLS headgasket and it will probably handle 300+hp, as the Sprinter rods are even beefier than OM606 turbo rods.
With supporting mods of course (big pump, big turbo, big intercooler etc).

As your engine is pretty much 4/5ths of that engine expect to be able to make 4/5ths of the power, and everything else is very similar if not the same
RE: om601 2.3 turbodiesel power limit - vica153 - 11-04-2021
^That dyno run of 220hp is with a 605 pump with 6mm elements and the 601 turbo pump presumably runs 5.5mm elements. I think that puts a 601 turbo with stock elements around ~65% the power, so ~140hp max.
I do like the air-water setup though and at 23psi boost hes putting enough air in to make 300hp with the big elements.

Sometimes one should read better before start making unpleasent remarks...
Btw 2.9 IDI do not exist in my planet, sprinters 2.9 around here are fitted with 602.8 DI.

2.9 IDI was found in vans around 1990 called 310D or 410D, and then later in Ssangyong.

Did we have a misunderstanding ?
For 1995-2000 Sprinter and Vito
208D, 308D, 408D Sprinter and Vito 108D
OM601 2.3 L non turbo ~80hp
210D, 310D, 410D Sprinter OM602 Direct injection turbo ~100hp, x12D same engine but different tune (120hp)
The only vehicle that Mercedes ever built and had OM601 turbo 2.3 from factory was the Vito 110D, it had also around 100hp.
Btw for Mercedes commercial vehicles it is very easy to know the engine power, last 2 digits multiplied by 10, but i guess most of you know that already.
Mercedes vans had a 602 2.9 N/A IDI (OM602.940) from 1989 to 1995 in x10D versions (210,310,410). This is the model before Sprinter, the T1
RE: om601 2.3 turbodiesel power limit - vica153 - 11-09-2021
Ha I kicked a hornets nest. I only used the term 'sprinter van' as a general term for those types of transport vans that we never really had over here until recently.
Anyway, I think we can all agree a 2.3 601 turbo can probably hit 100-140hp with the stock elements assuming they are 5.5mm. I think pushing the torque much above 200lb-ft would make me start to worry about the rods.
RE: om601 2.3 turbodiesel power limit - barrote - 11-10-2021
T1 vans then... well i guess those are not popular here , actually i've searched long time for a 602.9 then quit...
662's are common but is not the same cast...
RE: om601 2.3 turbodiesel power limit - Petar - 11-18-2021
Just FYI. I looked up the part numbers for the rods on the 601.970 and EPC says they are the same as in the 602.980 (Sprinter 2.9 direct injection). A6030303320 and A6030302920. Sprinter rods have been already proven strong by Baldur, so the 601 turbo will handle anything a 6mm pump will throw at it without problems, and will probably handle a 7.5mm pump too. So the only unknown is the head gaskat
It is interesting the 603 3.5, the famous "rod bender" has five!! part number revisions on the rods. And the final revision is the same as in the 2.9 sprinter, A6030302920
RE: om601 2.3 turbodiesel power limit - vica153 - 11-18-2021
That's good info to know. My hesitation about going over 225lb-ft on a 601 was based on the idea that the rods might be the same as the 603 that had bending issues. If they're revised sturdy rods then the 601 is likely safe to 300lb-ft.
RE: om601 2.3 turbodiesel power limit - barrote - 11-19-2021
Well , it is said.
Later i'll try to post s pictures of those infamous rods...
I have all kinds from 601 to 606, except 603D35.
What surprised me the most is the first gen 604's
