Take one awesome om604 engine. Put stronger rods and pistons in it, straighten and balance the crank, weigh all rods and pistons, get crazy camshafts to it and machine the pistons for clearance then send the pistons of for coating. Modify a BMW flywheel to fit the Mercedes crank and tadaaa you have a solid 4cyl 16v diesel.
Dieselmeken will build the IP.

Intake:
Centerline 112-degrees
Duration 280-degrees
Lift 10,6mm
TDC lift 1,7mm
Exhaust:
Centerline 112-degrees
Duration 280-degrees
Lift 10,6mm
TDC lift 1,6mm
This is what we call Stg2 cams. So nothing special at all.
(01-04-2015, 10:32 AM)raysorenson Would you mind sharing the cam specs?
Yes normal turbo engine bore and stroke
Yep new sleeves in the cylinders to achieve the smaller bore.
(01-04-2015, 11:00 AM)Petar What bore and stroke ? My guess is OM601 84mm stroke crank and 87mm 606 turbo pistons.Did you resleeve the engine for the smaller bore ?

I have no clue actually and that is a valid question. I'm NOT the camshaft guy really. I don't know anything of how that piece works. I just know from being in the flow bench that you need a little bit of lift to get good numbers.
The cam-guy we use calculate on stuff like this. Maybe it's time to learn

Will you be using aftermarket connecting rods? I certainly hope so - with the fueling potential of the Dieselmeken pump and what I suppose may be 2.5 bar of boost or so, the upgraded rods would be a nice insurance policy.
Steve.
This looks like a very interesting project. I can't wait to hear/see how well it runs.

AND it's pretty hard to find a tougher rod the same length as a 2.2-liter rod.(01-08-2015, 02:12 PM)erling66 Why do you want to reduce bore and stroke? Bore, I guess is because you want to use 605/6 turbo pistons. But stroke??? Normally more ccm means more hp.
2.5bar will not do it quite frankly, 3-3,2bar maybe. And yea it's a cool project. Just have to make sure the guy with the wallet decides for some forged rods

We use the 606dt rods in this application (for now).I have a set off each rods in the shop so will actually measure them

What coating are you putting on the pistons...ceramic on top and Teflon on the sides?
Are you doing any modification to the pre chambers?

Full coating (skirt and top) is 1000sek/piston. And yea, made in Sweden
The pistons are also machined for more valve clearance before coating.
