I have this same motor in my ‘92 350 GD. It’s terribly slow off the line and has virtually no power when on the highway going uphill. I have it loaded down with gear (I use it for Overlanding), so some performance downturn is to be expected. I’d love to get some more power, though. My question is by doing a mild upgrade like seen here, does the reliability of the engine stay high, and do I have to upgrade anything other than the pump to withstand the power gains and keep things from breaking?
i would like to ask you a question i have a w126 s class and i swaped the old n/a om 603 for a for a turbo om 606 and had to change the pump to a mechanical pump form a om 603 3.5 turbo so i was thinking will the engine make the original 170 hp or will it do less and if less can i tune the pump myself and how? just for like 180-190 hp P.S great vids love them keep them coming
What is the 603s capability with a decent pump and turbo setup ? I love the channel and want to get into an 0m606 but they aren't the most easy to come by in the States I see alot of the later models for cheap
How did you get the intake manifold off? Tips would be appreciated! Some screw's are a pain in the ass to get to. Aswell as torque it to specs when putting it together again.
Hi, I'm from germany and I am interested in upgrading my pump like in your video. What does it round about cost to have it done like in the video. Also I would like to know if it's possible to pass the emission test with this kind of tuning? Thanks and keep on with your videos, it's always a pleasure to watch!
@@JoeHeine unfortunately looking through this channel, they have removed the video where Luke puts up a pathetic video where there was an issue between DPUK and dieselmeken where DPUK was authorised to create pump parts but kept all the profits or some shitty behaviour. Other option is to go onto SuperTurboDiesel forum and look what everyone has to say about him.
Hello Luke i have question! Can i fit just turbo pump from om602 to NA om 602 without conecting alda! I just want little power gain without complications turbo installation!
Can you also do this to a OM602? Will the fuel consumption increase? I have heard that removing the alda cab also increase hp. Is it better to remove the alda or the element or the two?
Did you find out? Can you also do this to a OM602? Will the fuel consumption increase? I have heard that removing the alda cab also increase hp. Is it better to remove the alda or the element or the two?
Hello, how much to have this done? Also, no need to change others like turbo to get the hp and torque gains like the car in the video? What would be the effect on fuel consumption on stop and go traffic? I'd like to have power increase in a daily driver
Hola DieselPumpUK soy propietario de un Mercedes Benz W124 300D versión Sportline y me llamo mucho la atención este video y quisiera preguntarte algunas cosas sobre el asombroso aumento de potencia que se ve en los resultados del Dyno. Una de mis preguntas es : todo el aumento de potencia se obtuvo siguiendo los parametros originales o se alteraron esos parámetros para conseguir los más de 180 hp. Tengo otras preguntas tambien😬 Saludos cordiales desde Paraguay
Is there any videos with 602. I know 603 is almost the same thing just one more cylinder same idea. But just curious what kinds of crazy things you've done to a smaller 602
Fatality Diablo hi, this video is about extracting more power, it’s not about fuel consumption. This will use more fuel at wide open throttle, however cruising will be identical.

I thought that om603 had longevity issues? Especially when compared to om617 and om606? Or have I been misinformed about om603? What is the average useful life expectancy of the om603 with proper maintenance and "normal" driving? I actually avoided buying two with om603 because of horror stories. Many thanks for any info.
Not heard about any particular horror stories with the OM603 here in Scandinavia. Those cars now typically got 400-600.000 km, which are still on the road. Cars here rusts away long before issues with the engines, usually. It's a colder climate. In a warmer climate and/or driving the engine hard and fast (Autobahn) there be higher risk of issues with the cylinder head cracking and such. If one drives 'normal', and take care of letting the engine warm and cool off slowly/evenly, it should work alright for a long time.
@@maxkarilainen8711 That sound good. My 124 with OM603 has just 360.000 km. Have your engine had adjustment to the cam shaft chains, or not needed? What about other adjustments, valves? How often have oil been changed? Mineral oil or synthetic?
@@Rimrock300 I bought it from older guy and the service manual has been lost, he said that engine havent been opened so i think that cam chain is orginal but valves have probably been adjusted. I opened valvecover and valvetrain looked brand new. He also said that engine oil has been replaced regeraly (probaly semi syntetic oil) and its 1985 so its the 109hp version
The OM603/3.5turbo of the last year of release had no problems with cooling and head. They had a water pump from OM606 and some other differences. For engines of previous years, a pump from 606 is also recommended -a small grinding on the block will be required. (... used 603 for 6 years, replaced it with 606/7,5 - beast ...)
Different RPM.s Looking at the RWHP I see a gain of only 33 hp, about 33% adjusted the starting numbers up slightly for rpm. What I don't understand is how you lose so much HP between the Motor and the Rear Wheels on the modified. Unmodified, the loss is 25 Hp, modified the losses are nearly 55 hp. Something is not right here. My guess is your machine is not accurate estimating RWHP. zAlso comparing HP at different RPMs is not an accurate test. A 1/3 increase in HP is still nice.
Dennis Hedlund well done, however, that’s well over the turbos 1.6 bar efficiency threshold so no points for the pressure but power is ok. The point of this modification was to keep good reliability on all the factory components.
2:57 I didn't know half of the addictive mercedes diesel sound actually comes from the pump itself.
I've never seen such a beautiful OM603!
Great! Exactly what i needed to see, I want to leave everything stock except the pump. Nice to see these results.
I was surprised that it was just the pump upgraded without a turbo upgrade. So awesome!
Very happy to see one of your old videos ! You have gone a long way in 4 years… 🍀
Very impressed. I’d be chuffed to bits with that gain. Another job well done!
bowman_concepts well, he said it was leaking, so it would probably the main reason.
Boy I wish you were in Southern California! You’re doing beautiful work sir!
polished intake and covers look great.
Amazing result. 👍
I've been planning on polishing my intake and valve cover. Glad to see someone who did it so can can see what the results would be. Fantastic job BTW.
Less than you think... Mercedes heads are not bad. Maybe 1/2/3%.
@@lieberfreialsgleich So, in stock tune and properly maintained, how does om603 compare, as far as longevity, to om617 and om606?
That is a phenomenal gain love your work DieselPumpUK.👌
Have you done any work on the Mercedes 4 liter V8 Diesel engine? If so what gains have you managed to get?

Use dieselmeken in Sweden, not this clown. He is two faced and a robbing little git.
@@jumpspace7414 what did he do ?
if i put elements in fuel pump of 5,5mm wich power can get on original turbo on mercedes om603 turbo ?
Did you change the pump, or did you rebuild/tweak the old one?

300 hp might be within reach, but going more than 180 or so the original automatic transmission don't hold up well, from what I've heard
In a w124 603,912 no turbo, can the pomp be tunned, to run a little stronger?
How did you get the intake manifold off? Tips would be appreciated!

I got a om603 and im looking at both DPUK as well as DIESELMEKEN. COOL VIDEO.
How far can you turn that OM603 up to?
1:07 is it a Dinosaur screaming as the door closed on its tail😂
Any idea on mpgs with the new pump?
The 1988 model 300.Td om603 automatic transmission lifts up to how many hp. thank
Must have been something wrong on this engine with just 115 hp output? Quite big difference from theoretical rated147 hp as new
most likely rated at flywheel not at rearwheel
Well if the pump was leaking it was not ok
@@jpvalve dude, Luke showed the 115hp at crankshaft.
Of course, there was something wrong. 20% less than original, even after 300000 mls, that‘s a lot.

No intercooler? Straight from turbo conpressor output to intake manifold?
Can you also do this to a OM602? Will the fuel consumption increase? I have heard that removing the alda cab also increase hp. Is it better to remove the alda or the element or the two?
Do you have any idea where the coolant lines of the Wabasto connect? I can't find that info anywhere no matter how hard I look. No one seems to know.
Is this a better motor versus an NA OM606? Trying to figure out which w124 to buy and the US has limited options
Think the Alda was not working at the first run Aswell, because 116 engine power is way to low for a om603a
Nice no electronics involved...
Good old mechanical advances
How would this pump work on a 603 non turbo?
👌👌👌👌👌👌👌👌
how are the gains with a om606 pump? I would like to do a historic worthy tuning.
Are these 603's as good as the 606's and how hard can one expect to push them before they give up.
I personally would not push them to more than 400hp, and to make that power you need much work on cooling
How many degrees did you set the timing on the dieselpump after upgrading to 6mm element? The same as original or less?

So can you take the percentage of fuel pump flow increased and estimate the increased fuel consumption by only that parameter, or is there more to it?

There is a lot more to replace than just the turbo.
