W202 220D om604 +P - F.R.A.S - 01-14-2015
For you guys out there in to guns you know that a +P round is a hotter round with more punch and power. That's my om604
The car was test driven today so it's almost done. However some of you like to see some pictures of the build and some technical info so here goes.
The car is a Mercedes C220D from 1993 with the 2.2-liter n/a om604 and 95hp.

The plan was to make a decent daily out of the old lady.
Said and done I got my self a Injection Pump from the Mercedes Vito with the 2.3-liter turbocharged om601, high RS-number mechanical IP
Sent it of for some adjustments @ Dieselmeken and there is where it all went wrong...
When the pump came back to me it had 8mm elements and was capable of 180cc of fuel. So ditch the plan "decent daily" and start a new one called AWESOME DAILY
Bought myself a couple of items for the car.

Second test drive today. Boosted 1,2bar yesterday and 1,6bar today.
The car is really coming to life with a little extra boost.
Had some leaks so have spend half the day pressure testing and sealing stuff. Did 2,5bar with the tester and now everything is sealed and done. Also checked the boost gauge for accuracy
Only doing 500-degrees Celsius EGT today so I know we're out of fuel. Will adjust the IP tomorrow and do some more testing.

RE: W202 220D om604 +P - F.R.A.S - 01-15-2015
Have only been driving 3-4km so far
Have been using a lot of clones before and they usually holds up just fine. It's a big difference in quality on the clones and we have pretty good sources (how ever this is the first turbo like this from our supplier so I have no idea if it will last or not).
Thanks mate.

The car looks good, like a Wolf in Sheep's clothing. Maybe a good place to test a 400HP OM604?
The wheels on my 'Benz are old-school Mille Miglia 5-spokes. 2" center caps. Are the F-Tune center caps adhesive-backed decals?
Steve.
RE: W202 220D om604 +P - F.R.A.S - 01-15-2015
Yea it's a bit of a gentleman racer that goes under the cops radar
Yea it's 3M-dome decals but I have to order the exact size for it to look great. In the case off those already made we measured the inside off the small rim on the edge off the center caps. Inches are really a rough estimate
If I could get a measurement in MM that would be great.It would be possible to mount another engine in this chassis and test it out
but I don't really think that is a good idea.(01-15-2015, 05:04 PM)Jetmugg The car looks good, like a Wolf in Sheep's clothing. Maybe a good place to test a 400HP OM604?

Third day off testing. Boosting 1,9bar so far and everything looks fine. Car starts to loose grip on third gear and that's great.
Was going to take the car home but had an oil leak so have to fix that first.

RE: W202 220D om604 +P - F.R.A.S - 01-16-2015
A diesel only boost what you have fuel for. The boost control on a STD is to LOWER the boost to get maximum power (EGT). If letting the turbo boost maximum you will have something like 650-degree Celsius and maximum power is in the range of 850-degree Celsius.

RE: W202 220D om604 +P - F.R.A.S - 01-17-2015
Have been driving with the stock 115bar injectors till today. Everybody says that the injectors have to be changed so I had to test with the stock ones
The om604 has Lucas injectors and not Bosch, same stuff more or less but nice to know.Now I have fitted some upgraded Lucas injectors set @ 160bar, what I can see I have lower EGT by 100-degrees with means a cleaner and more efficient combustion. I also have 0,1bar more boost with nothing else changed. So 2bar even right now.
The car reacts a little better at speed when flooring it. However the differences is really small and for now I have to say that any injectors works equally good. BUT I have not tested this more than 30km (180miles).
Note: We have actually never tested this before and only done what told, fit higher pressure injectors, that's why I had to test

RE: W202 220D om604 +P - F.R.A.S - 01-22-2015
Alright guys
I run a Holley Black clone electric fuel pump because it's easy and some guy told me the Finns have done 700bhp with one. I know absolutely NOTHING about carburettor setups and such so I've been struggling with this for a while now.
Turns out that the Holley Black is made to only give 0,5bar (7psi) off fuel pressure and it don't need a return line. I have a return line
Today I changed the spring that controls fuel pressure in the "Holley" and have an unknown fuel pressure at the moment (will measure later on) and WAOW what a difference
The boost gauge is only good for 2bar (28psi) but I have pressurized the system and know where 2,5bar (35psi) are. However the boost gauge is flicking around like a maniac and I only know I have somewhere between 2,3bar and 3bar.
It's a bit slippery on the roads with 18" and summer tires and we have melted snow on the roads so couldn't test it as hard as I liked.
Ass dyno says 350hp and it's a maniac already
RE: W202 220D om604 +P - DiseaselWeasel - 01-23-2015
Carburettors usually have a float & needle pin to shut of fuel supply to the fuel bowl (from which fuel gets sucked into the nozzle/jets of the carb). Hence the fuel pump may not overcome the needle pin. If it would, the engine would severly overfuel (pump pushes fuel into carburettor). Usually they'r membrane pumps, iIRC. You'r probably better off with a different pump. But if it works for now - all good!
Going to the dyno with this? Would be very intersting to see what the "little" engines can do!
RE: W202 220D om604 +P - Max - 01-23-2015

The last time i went to my local Scrapyard, a om604 was laying around there "for free" (only Metalprice).
I should have taken it with me....

So guys here is an update for you
Had this C250TDT rear end laying around so welded that diff and mounted it on the 220D
Mmmm, drives hafts didn't fit, had to swap to the 250 ones...
...prop shaft didn't fit so thought of using the rear end of the 250 prop. Naaa didn't fit, the splines where bigger on the 250.
Have to use the entire prop. NO, not that either, the prop don't fit the gearbox.
So I have to cut and weld the last bit of the prop
Easy swap right!!!

RE: W202 220D om604 +P - F.R.A.S - 01-31-2015
Thanks mate.
The turbo is awesome and works great. It feels like a bigger engine really, I have 0,1bar @ 1500rpm and then the boost is climbing slow and nice up to 1bar @ just under 3000rpm and @ 3000rpm I got 2.5bar.
So slow steady build up of boost up to 1bar, then it's just like someone hits you in the back and you get all the boost you could ever need at once. Drivable and fun at the same time.

Here is some pictures from today.
Had some problems with the new differential so the solution was to take the driveshafts from the C250tdt and cut the propshaft and weld them together.
Fist I machined a sleeve (56,8mm) that fitted nicely inside the propshaft and then it was just a mater of welding

(02-03-2015, 12:49 PM)raysorenson I'm going to have to do this soon. I had a custom driveshaft with U-joints (cardans) made and the noise and vibration is awful. I think a U-joint at the trans and a big flex disc at the diff should be a good enough compromise.
Ok Guys, here is the first clip of the car in action.

Excellent work, that exhaust manifold is really looking nice. I'm very interested what power is it making, engine is stock?
RE: W202 220D om604 +P - F.R.A.S - 02-03-2015
Thanks mate.
It's a completely stock om604, not even changed valve springs.
One or a couple of hydraulic lifters are jamming from time to time but it's all good
If it was a petrol car I would say 350bhp easy. But diesel have more torque so I can have less power. Only doing 2.5bar of boost so who knows
If doing the math I have approximately 105-110bhp n/a (95hp with stock IP) so lets agree on 100bhp.
1bar should land me in the region off 200bhp, 2bar 300bhp and 2,5bar 350bhp. If I have 300whp I'm happy.

RE: W202 220D om604 +P - erx - 02-03-2015
300whp from stock 604 is not sounding too healthy I think.
RE: W202 220D om604 +P - F.R.A.S - 02-03-2015
Why not?
You ever heard about anyone breaking one? I have not...

Something was lost in translation I think, I was just meaning it's more than superb from stock 604.
RE: W202 220D om604 +P - F.R.A.S - 02-03-2015
That happens
It's all good mate. Next project is w202 or w203 with om606 (02-03-2015, 03:46 PM)erx Something was lost in translation I think, I was just meaning it's more than superb from stock 604.

Now that you have turned the fuel pressure up on your Holley black, are you still using the return line or blocked it up?
What injection pump?
Cheers,
Max
RE: W202 220D om604 +P - F.R.A.S - 02-03-2015
I'm maxing out the Holley Black. Might be better without return line but I still have mine (factory restriction though).
Dieselmeken 8mm injection pump.
Will build a REAL fuel system soon, just have to figure out the most easy way off doing that with stock fuel lines.

RE: W202 220D om604 +P - maxypriest - 02-04-2015
Thanks for that. I have a dieselmeken 8mm pump on my w124 606 with a real Holley black.
I have yet to start the car, however have been thinking wether the fuel system is upto it. Sounds like it's ok to begin with.
RE: W202 220D om604 +P - F.R.A.S - 02-04-2015
It's not worth the trouble really.
If I where to build the fuel system today I would have used the stock lift pump on the IP, route it via the diesel filter to a small (maybe 1-2liter) catch tank and then go Bosch 044 from there to the IP and use a FPR (as supposed to) set at 3bar.
Return line from the IP to the catch tank and return to fuel tank from catch tank. Just as a normal high power fuel system.
That is the most easy way of doing this on our cars that don't have an in-tank pump. If the om60X-engine are in a BMW or similar car there is almost always an in-tank pump and then it's dead easy to just swap that to a beefier pump and be done with it.

(02-02-2015, 02:29 PM)F.R.A.S Here is some pictures from today.
Had some problems with the new differential so the solution was to take the driveshafts from the C250tdt and cut the propshaft and weld them together.
Fist I machined a sleeve (56,8mm) that fitted nicely inside the propshaft and then it was just a mater of welding
I got my prop modified with the correct 6 speed end at a prop shop, they ballanced it too. Cost a fortune! Anyway they also inserted a sleeve. Ballanced too as a whole unit.
I see. Thinking of alternatives I was also going along these lines with an electric lift pump into a swirl pot and running a 044 from that with a RR FPR connected to the plenum.

Did you include a slip joint on the driveshaft ?? The reason being is that the engine is on rubber mounts, the transmission is on rubber mounts and the differential is on rubber mounts. Everything moves a bit. Normally the rubber flex discs absorb the movement but with U joints you are binding everything together you are looking for trouble. FYI my mercedes t1 van,om617 engine, has one u joint at the transmission, a center carrier bearing with a slip yoke and a driveshaft with two u joints between the bearing and the rear axle. It has no noticable vibration.
RE: W202 220D om604 +P - F.R.A.S - 02-04-2015
Prop looks good.
DO NOT connect boost on the FPR. Turn it to 3bar and leave it there.

RE: W202 220D om604 +P - F.R.A.S - 02-05-2015
Alright guys here's an update for you.
Blew my head gasket
So when ripping the head off what do I do??? Yea I change rods of course
Going to custom make new rod bushings to be able to use the stock 26mm wrist pin.
And I'll build a small catch tank for fuel so I can use a real fuel pump and a FPR and boost 3.2-3.5bar in my little om604
Awesome day in terms of decision making
Only problem is that the car will be stationary for a month or two
or three.

Why are you going to use separate catch tank for fuel? I have 044 pump with FPR under the bonnet, fuel lines under the body and fuel tank are stock. I made it like that - fuel comes from tank to 044, after 044 there are FPR and from FPR overflow is not going back to fuel tank but it's running in little circle under the bonnet back to 044. Return line to fuel tank is stock from filter housing. I have fuel pressure 1 bar on idle and about 3 bar on max boost like Dieselmeken recommended. Maybe if I take picture you'll understand what i'm trying to explain.
