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
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.
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?
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
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?
He changed the elements from like 5.5mm to 6mm and put a more reliable and simple alda. The alda moves a rod in the injection pump to add fuel or lessen for altitude fuel adjustment. But he coulda have adjusted it alot more in this video if he wanted more power.
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
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 ...)
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.
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?
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.
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
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!
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.
hola saludos desde Argentina tengo un W124 con OM 603 y estoy enamorado de este motor consultá es cuántos hp se le pueden exigir a los pistones y bielas originales gracias saludos
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.
