new member and OM606 questions, hopes, dreams and aspirations...
I was referred here by a member from Hybridz.org named MAG58.
I do not have a mercedes, but I hope to at least have a mercedes engine in my car someday! I have a 1980 datsun 280ZX that I have been trying to decide what to do with for a while. Ive got the body (kaminari full widebody kit), brakes and suspension nailed down, The trans and rear end will consist of a 1988 300ZXT trans (.711 OD 5th gear) and a 3.36 R200 rear end. Both are known to hold up to built v8 swaps, Twin turbo engines running in excess of 600rwhp and 600rwtq in a 3300lbs car. My car weighs closer to 2800lbs. The engine was something I have waffled on for a while.
I think I have found the answer in the OM606 turbo. From what Ive been reading, its possible to get almost 500rwhp on stock internals, although 400rwhp seems a more sane goal. It will run on WVO, and it will get good mileage.
questions......
1. If I wanted say, 450rwhp, what sort of economy could I expect with an engine set up to deliver that type of power with healthy amounts of boost? Ive already got an HE351ve turbo laying around as well as a trans and rear end that should allow me to cruise at 60mph @ 2000rpms.
2. Is there anyone in the states that does the kind of work on these IPs that is required to get the HP levels I seek? I know of Myna in finland, just hoping for something more local.
3. Has anyone ever messed with porting heads, ceramic coatings on pistons and combustions chambers (maybe pre chambers?) on these engines? Im assuming a few gasser performance tricks still transfer over to these oilers. Maybe shotpeening rods, stress releiving, cryo treating, all that crap......
sorry for the long first post, but I feel too much information is better than not enough (well, in most cases anyway HA ha!)
I am looking forward to being a productive member of this board.
oh, and yes! I have seen the vids of the 240Z with the OM606 stuffed into it! that thing is SWEET!

I can get a 1999 OM606 without the turbo or IP for $1495. would that be a good deal?
N/A engines are cheaper yet, with some popping up in the sub 1000 range.
another quick question..... what are the major differences between an NA OM606 and a turbo OM606? aside from the intake and pumps? are there internal differneces? as far as connecting rods or camshafts?

There are oil nozzles for pistons as well in N/A engines. Rods are stronger in turbo and pistons are different (not proven to be more durable, as high hp engines have been built with N/A pistons). Get a decent, low-mileage original, non-opened turbo engine. If everything seems ok, better not to even change bearings "just in case". Original parts (which were assembled in the factory) are better quality than replacement ones nowadays.
Drove the OM606-240Z the other day. The most exciting car I know, too bad it isn't mine.

The camshafts are also different. Non-turbo engines have valve overlap to provide cylinder scavenging. Turbo engines have none, otherwise the high backpressure would push some exhaust back into the cylinder.
Ah, forgot to mention the cams. N/A cams also have more lift. Seems that those are better than turbo cams, since many 605-606 setups have shown clearly more power with N/A cams than similar setups with turbo cams. Been looking for N/A cams for a year, too bad you'll have to buy the whole engine to get ones..
(05-10-2010, 06:47 PM)McAdam can you swap heads between the 606 and 603?
No. The pistons are completely different.

(05-10-2010, 06:47 PM)McAdam ok another stupid question......
has anyone ever made a 3.5L OM606?
can you swap heads between the 606 and 603?
3,5L OM603 don't hold together even nearly as well as 3,0-litre ones. Too thin wall between cylinders, change head gasket with oil.
