OM617A Setting
OM617A Setting
I own an old G300 GD mercedes with the old OM617 engine. Since it has no turbo and weighs over 2t, it runs very very slowly with it's 88 ps.
I was thinking about making an upgrade to an OM617A engine with a turbo because it is very easy to mount and only the intake is different. I live in Romania and these engines are very rare here, since they where used only on a few w123 and only in the american w126 300 SD.This is the reason why i need your help.
Since i want to swap the engine, i was thinking about upgrading the turbo & pump before mounting it on.
I have read a lot of threads on this engine but it is not clear which would be the best combination.
For the pump, i think that the best solution would be the one with 7.5cc elements from dieselmekken,or? As for the turbo, i do not know what to choose in order not to modify the whole intake. Do i have to change the stock injectors when changing pump and turbo?
I do have about 2500 eur for this project and do not want to swap any internals in the engine. What max power can i expect with stock internals from this engine?
Do you know if there are any aftermarket intercooler kits for this engine?
Ps: please excuse my english if i do mistakes. I also have a lot to learn about engines
Thanks a lot

I belive i have a turbo set too. Original to 617A.
Maybe i can help u out with some other issues.
The injectors may be the same as N/A although the precups are diff. Upgrading to turbo ones includes cutting on the head nothing special.
But u may already have the turbo type head and engine with oil squirts.
That is something it needs. Then its about it.
Its the turbo and the pump that will make all the diff.

How can i see if i have the needed pistons and oil squirts? I do not know which mecanic would risk and drill the oil squirts in the engine block here in Romania.
What turbo set do you have?
Please pm me about the pump.
Thanks
Sebastian
Hello and thanks for the answer. If i understood you correct, does it mean that i can upgrade my engine to the turbo version? That would be great, since i have the engine serial number in the documents of the car and would not have to change the papers with the new engine serial code.

I have original turbo from 617A.
U can check the squirts by removing the pan. Or asking MB by the engine nr and chassis nr.

If u have a original gd300 probably it is the latest engines produced. Being in an ofroad vehicle must have oil cooling and piston cooling.

I do not have hope that MB will provide me this information if i send them my engine or chasis number.
The car is an G class 300GD built in 1986 with the original engine.
Thank you
Hello Barrote and thanks for your answer. Do you have any picture on how the squirts for the turbo version should look like? You mean that i should remove the lower oil pan, and i should see there the oil squirts and oil cooling nozzles, right?

Yes they have it in the system... they implemented the Epc in early 90thies when your vehicle was still under 10 years.

There is one mounted at the bottom of each cylinder.
And yes you have to remove the lower oil pan (the big one with like 20 allen bolts) in order to see them

I do not have these oil nozzles. I do not know what to do,but i guess that a small turbo will not destroy the engine in time.
Is there any possibilty to mount the oil nozzles or do i have to start making wholes in my engine?
In this condition, what would you advise me to do? I have seen that Barrote has a nice IP for sale, but i do not know what would be the result if i couple that IP with a turbo and some bigger nozzles? I have also seen some setups with the standard IP + nozzles and a BMW GT2256V turbo, which worked as far as i know on the long term.
Thanks in advance.

I went to the MB service and NZScott, unfortunately you are right.

Just run cool EGTs and you should be fine - that's what I plan on anyway.
New (injector) nozzles aren't necessary if they work ok. Yea sure I put some 315s in... but they're not needed for power

I was going to install nozzles in mine - but needs to be completely torn down for that, and I have a 617.952 in my garage needing some work so I didn't worry.
