I'm about to putt a OM603 Turbo in my Mercedes G. 1988.
But I want more low end torque. I'd love to have about 300 Newton around 2000 rpm.
180 hp would be fine for me. They are not so necessary for me.
How would do this?
What turbo etc.?
I need the car for difficult off-road, and to pull heavy trailers and caravans.

I can help you out with all your manual transmission, clutch, flywheel, intake and exhaust manifold issues.
Eaton M90 supercharger every day. Make the crank pulley 4-times the one on the SC and you have full rev on the SC @ 5250rpm. The times you rev more is no problem cause it's only be for a moment.

use your originalturbo or something like the KKK K14 out of W210 300 turbo
a nice intercooler and 7.5mm elements,
for much torque and only180 hp out of the OM 603 this will be enough and
yout max rev you can set at the originale 5100 this is enough for a 4X4
i think you use it for trailering and such works

the w210 KCR chip:
Original 177 hk
KCR-Box 205 hk
Original 330 Nm
KCR-Box 370 Nm
So the original kkk turbo would at least be able to do 205hk even in a 603 right?

Also would like more torque lower down, it pulls like a train once the turbo is up and running from about 2000 revs but that is too late offroad.
Om606 with mechanical pump with 6 mm elements.
Supercharger is sadly not possible as i already run a big hydraulic pump for my winch so it is crowded in the engine bay!
I have purchased a 350 sdl mechanical pump now as it would appear they already give some more oomph than a 300 pump which I have now.
So The question is: do I go for 6mm elements or 7mm.
Will the 7mm give more torque lower down the rev range and will they work with the standard little turbo.
As the original poster not too bothered about hp but grunt loooow down.
Air/water intercooler already installed and a 80 mm free flowing exhaust as well.
Hope it was ok to post here
Thanks in advance

Hi, sorry to hijack this thread a little bit, but really the same question for a om606 powered g wagen.

Super small compound? Like a Garrett GT1752S from a SAAB 9-5 and then the turbo off your choice, like a HX35 or similar.

VE is worse so say 195hp (my earlier answer was for the VNT-turbo)

If you ask me you don´t even need a bigger turbo or injection pump for your goal if you start with the 147HP version of the OM603A
- exhaust temperature gauge
- get rid of EGR
- a nice BIG intercooler
- increase turbo pressure to ~1,0-1,5bar
- Greazzer´s performance overflow valve
- a 76mm free flow exhaust
- injection pump full-load and ALDA adjustment
Those mods were done to a friend´s OM617A and made ~30% more power.
before 125HP, after 165HP on dyno

i have a 605 with a dieselmeken 7.5 pump which i am going to put in an off road buggy, like the idear of fitting the eaton m90,is there any thing i need to do other than fitting to side of block and plumb up and away we go or is it more complicated.i too are looking for torque and quick response cheers gary quick pic of buggy too
