mercedes diesel in a dakota - winequip_td - 12-03-2010
Im looking at putting either a 603 or a 606 in a 2002 dakota quad cab 4x4 5 speed. This is a 2 part question.
1- I have a line on a 606 na engine, would this engine hold up and be reliable if I put all the turbo goodies from a 606 T on it? im looking for between 175-200 hp and 250-300 ft/lbs
2- could a 603 T be capable at producing the same output and being just as reliable they are much more plentiful here in canada.
Im aiming for a truck that drives just as good as the v8 but gets about 30-32 mpg.
thanks for the info
Nathan

The non turbo engine's usually don't like a lot of boost!

You should use a 606 Turbo engine, but rather a 603 turbo than a 606 N/A.
RE: mercedes diesel in a dakota - E300TSC - 12-04-2010
You can add a turbo to the NA 606 but it's not as robust, lacking the MLS head gasket and improved pistons and rods of it's turbo sibling.
The stock 606 turbo delivers 177 HP which moves my E300 very well. This is the same HP as the V6 Dakota but with better torque. Performance at stock levels would be similar to a V8.
As far as mileage, I would expect no more than about 25-28. That truck is pretty heavy and not particularly aerodynamic. The most my car has delivered is 32 in stock configuration.

OM.606 N/A engine is a pretty robust beast. According to the Finns--who have extensive experience with the 606 you can shove a Turbo on there with little worry about its internal strength up to around 300 odd BHP
Bne Fine and fully reliable I should think up to 200BHP which is more than the stock 606 Turbo motor and prolly Much better than the engine you're removing.
The 606 N/A engine has the advantage over the earlier 603 in that its a quad-valve machine so breathing is much better so will respond to 'tuning efforts' better than the 603.
It HAS got the cooling oil-jets for the pistons, similar to the turbo, but the pistons ARE different to the turbo motor.
For much more than say, 300BHP you'll need to replace the pistons, the rods, the H.G. maybe some other stuff.
IF you can find a Turbo motor to start with, you'll not have ANY worries about tuning, these are Incredibly robust. BHP figures of 600BHP have been achieved by the Finns without any internal mods....
In ANY tuning efforts, (On any engine) watch the EGT's carefully and keep them to a safe level....

My only issue with the OM606 is I notice a lot of the early naturally aspirated units seem to suffer from cracked cylinder heads mainly due to overheating,normally caused by a blocked radiator/faulty fan/faulty thermostat etc... I think this has to do with the smaller clearances between the valves compared to its predecessors. To be fair....later OM606s(turbocharged units)don't seem to suffer from this as much....perhaps Mercedes' continuing philosphy of engineering improvement cured this? The turbo The OM617 & OM616s rarely needed a head....just a skim and a head gasket.....the OM 601/2/3s normally got away with a skim and a gasket and the occasional head
RE: mercedes diesel in a dakota - ben2go - 12-04-2010
Factory turbo 606 with a 603 IP would be great for future performance mods.I never heard of 606 having head gasket problems, but the first years for the 603 did have head cracking issues.
RE: mercedes diesel in a dakota - willbhere4u - 12-04-2010
The om603 turbo had head cracking issues but Mercedes sells updated heads for them still
ask me how I know mine still has the original #14 head and it cracked!
RE: mercedes diesel in a dakota - winequip_td - 12-05-2010
Thanks for all the replies, the reason i was asking is I can get a NA 606 with 200 kilometers for 300 bucks. I could also get a factory turbo 603 as well they are plentiful in Canada and relatively inexpensive. I bought a rebuildable core for a 190d super-turbo project im working on, fully dressed with all accessories and pump for $400. I just know the 606 was a better designed engine with a higher volumetric efficiency which would equal better fuel milage.
RE: mercedes diesel in a dakota - yankneck696 - 12-05-2010
As previously stated, you can safely do 300 HP with the 606 NA. I would think that will drive the Dakota along just fine. For the price you can get it, I'd jump on it.
RE: mercedes diesel in a dakota - 300D50 - 12-05-2010
Buy it.
Use it for a week.
Sell it to me for $20
I'm jelous as all green men that you could find a 606 so cheap...

Well, I think I can go one better!
Bought a complete 1998 W210 Minus its wheels, with 130K on it and in good running condition with OM.606.962 Turbo motor for what actually amounted to £100!
(removed engine and sold body on and recovered some cash)
My 606 all cosied up in the garage under some thick Welsh blankets waiting patiently....
Yup, My advice is Grab that engine while you got the chance, the way I look at it, IF for some unknown reason you blow it up (Unlikely, unless you do summit Really daft) or the project changes, Not much financial loss, you could always sell it in the case of a project change...
RE: mercedes diesel in a dakota - George3soccer - 12-05-2010
I sure as hell would love to pick up a 606 NA motor for that cash, and build it on the side Over the winter. Would be doing it to my 603, so either way the money will be going in a motor.
RE: mercedes diesel in a dakota - winequip_td - 12-06-2010
Ya Im just finishing up a rebuild on a 603 for my superturbo project, it too bad i couldn't find a turbo 606 instead but this will be a good start. I thought the NA engine would be strong enough to support 200 hp and 240 is ft lbs reliably in a truck as a daily driver with the odd towing. I just wanted to get opinions on the subject, out of curiosity will the 603 rods and pistons work in the 606 or are they a different design. The 603 engine is quite common wrecking yards around here.
RE: mercedes diesel in a dakota - willbhere4u - 12-06-2010
They are different I wanted to put the 606 head on the 603 block but the relifes in the pistons are diffrent
The Finns are getting 300+ HP out of a NA om606 so it can be done!
They have smaller rods and smaller wrist pins than the turbo 606
and the oil jets and pistons are different the om606 turbo piston have internal oil cooling or something!
The most important part to getting that power is having an injection pump shop build a super pump! that's the expensive part!
a tuned stock turbo om603 can support about the power numbers you are looking for! or around 400hp with super pump and big turbo!
a NA 606 can do 300hp modified with pump and turbo
and the om606 turbo +600hp has been done with pump and turbo work!
