OM605 and 7400rpm - Page 3 - PeachParts Mercedes-Benz Forum

Hmmm...

I remember the article, but I'm sure it was a OM.662 from Ssangyong Musso TD....
--Apparently he imported engine from Europe somewhere...

--Basically this is OM.602, 2.9 litre Indirect-Injected engine, made under licence single-overhead cam...

I believe the basic block of 602 and 605 are the same, so same mount-arms used from W201/602 should work out....

I have a question related to the motor mounts for installing the OM605 into a W201 chassis. Are the motor mounts for this application (the aluminum arms which bolt to the engine block) the same mounts as used for an OM602 into a W201 chassis? Are you using stock motor mounts, or have you made something custom for this installation. Any guidance would be appreciated.

Thank You,

Hi and thanks. Dont still know of world leader.
You can use OM602 engine mountings, those go straihgt on.

I have done mountings my self, because i didint want those hydraylic rubbers.

Here is couple photo where me and my friend do engine swap 602 to 605

Thanks again for all the information sharing Jeemu. It's guys like you that keep advancing the knowledge for everyone.

I'm curious about the motor mounts you used. Did you replace the hydraulic mount with a solid piece of polymer, through-bolted from the upper mount arm to the subframe? Or some other design, perhaps a solid metal mount?

I am trying to learn as much as possible about the OM605 setup, as I would love to have a 605 turbo in my 190D. As you may or may not know, the 605 engine was never offered in the USA, where I am located.

I am researching the possibility of transferring a 605 cylinder head and corresponding pistons onto my OM602 engine's block. I think I can import a cylinder head at a reasonable cost and start working on the swap. The OM606 pistons are the same as OM605 pistons, correct? So if I had OM606 turbo pistons, they will work in an OM602 block with OM605 cylinder head? At this point, I'm just thinking out loud, looking for any feedback.

Thanks again,

SteveM.

Hi. Jetmugg.

Yes i replace hydraylics. I have BMW 524td (e28) rubbers and i have modded original mounting arms. Welded on aluminium on them, so height is as original.

Do you have turbo or N/A engine. Turbo has 2mm bigger piston pins.
My engine is made a 605 N/A and i put om606 rods and pistons.

It is possible install 605 head on 602 block

Jetmugg · #35 08-25-2010, 01:26 PM

I have a turbo OM602 - I didn't know that about the bigger wrist pins.

Will OM606/605 turbo pistons be a direct replacement for the OM602 turbo pistons? (can I retain the original 602 rods and hang the 605/606 turbo pistons on those rods to achieve the correct configuration)?

I guess I need to spend some time with the Mercedes Electronic Parts Catalog, cross checking part numbers to see what will interchange.

If I had the correct OM605 turbo pistons, an OM605 head gasket, OM605 cylinder head and fasteners, is that the biggest part of the mechanical puzzle? What do you know about the timing chain - is the front drive sprocket for the 605 in the same location and the same number of teeth as the 602?

Are the cylinder heads the same between an OM605 non-turbo and an OM605 turbo?

The injection pump setup, turbo, intake and exhaust manifolds would have to be sorted out as well, much of that work would have to be custom anyway.

My head is spinning with possibilities.

om605/6 pistons go straight at 602/3 rods.
Here people use 605/6 rods on their 602/3 because those are stronger.

Also here is use 605/6 head gasket on 602/3 engines because its mls.

It have to drill couple holes in it. So some differenses those have.
Not know what holes those are, but i think water.

In my opinion is that you bui compete 605tbo engine.
Maybe England?

Here is photo of those mountings

When i go back to work, i can take picture of 605 and 603 gasket.

Jetmugg · #37 08-25-2010, 02:12 PM

Fantastic - thanks for the pic of the mount - I like it much better than the hydraulic unit. I suppose the BMW piece is solid rubber with inserts for the bolts.

I am investigating buying an engine from the UK or Germany and having it shipped here - it will just be a matter of cost differential between shipping an entire engine and shipping just a cylinder head.

I have seen pictures of the 605 and 602 head castings side-by-side, so I have seen the extra holes - I guess the extra holes are not required if using a 605 head on a 602 block?

That is nice and iteresting project. I have in garage at 601 what i build powerful engine and planning to put that 604 cylinderhead.

Maybe someday. Now all time goes on this 605 and m104.

jeemu · #39 09-01-2010, 04:47 PM

Today installed 6 layer mls cylinderhead gasket, big bore prechambers and bigger nozzles.

jeemu · #40 09-03-2010, 11:37 AM

Today i drive some tests. Turbo spools faster and seems at there is a lot more power. Next little more fuel and boost.

I would love to see a dyno run to see what the big bore Prechambers and larger injectors do, (with out touching the pump besides timing adjustment).

Any idea if the timing wants to be more advanced or retarded with the new set up?

Hi. I go dyno when we get new one done.

More advance can use, because pressure on chambers are drop.
I advanced 2 degrees, max boost comes much faster.
Only bad thing is at wheels spin much easier

jeemu · #43 09-19-2010, 03:56 PM

Start to loose some weight of that car. Best way do that is put engine lighter chassis.

jeemu · #44 10-03-2010, 05:22 PM

Nothing much done. Made engine mountings and intakemanifold parts are good shape. Exhaustmanifold have to do or bui new.
Today bought typ188 read diff with 3.15ratio. It goes 6000rpm 4th gear 207km/h and 5th 250km/h, but have to remember at this take 7000rpm
Couple things is on what we do to engine on winter so more power can be wait of it.

will see is there 600hp in next summer
