why trash a perfectly good mercedes? leave it stock and build some other diesel.
thats my advise

I am asuming you want a diesel though? If you want an I6 you are pretty much limited to a 603. Good running used ones can be had for $1k+/-, usually more.

I intend to install propane injection as soon as I can. It's all waiting on $$$. There are plenty of posts and threads here to go with for a proper OM617 install. I'll be using a new acetylene regulator and run around 2psi of propane.

I don't know where the "high revving" Detroit idea came from, an 8V92 was only good for 2100rpm (supercharged and turbocharged).

A blower will keep bottom-end power up, but the turbo is the real deal. If you want low-end with a turbo engine twin sequential turbos is the way to go, spin up quickly for low-end and then two turbos for high-end.

Turbocharging a NA engine isn't going to be the most stable upgrade, the turbo engines use oil-cooling sprays on the pistons to keep things cooler, and I believe sodium-filled valves to keep them from hot-spotting, might be wrong on the valves as I'm not iinside the M-B diesel yet ... but the point is to start with a turbo engine and build it is the better way. You typically want lower compression for a turbo engine, and if you're adding a lot of turbo boost an intercooler to cool the intake air will give you much more power and save the engine from the trauma, LP/propane is another way to get some extra power and cool the charge, have friends with it but I haven't tried it.

There are a few guys on here who are pushing their turbo-diesels pretty hard, I'm happy to learn from their successes and mistakes, there is a lot of power to be had by simply adjusting the ALDA, increasing the wastegate pressure/turbo boost, and turning up the rack for more fuel. If you want to get more RPM out of it also you'll likely need to change nozzles, change cam profile in the pump, and probably change the max. advance in the pump.

Mechanically injected engines leave lots to play with.

Full speed ahead.

They did not revv any higher than other diesels in that size class. They just sounded like it because it's running with twice the # of powerstrokes per rotation. It got the name "Screaming Jimmy" for a reason. Remember the Detroit motto, "When it stops leaking, it's out of oil!"

What year did they start to make the 603 because the older the engine the cheaper it will be for me to purchase.

I have a very limited budget.

The only reason i am asking about these really exspensive parts is because i have some friends that can get them for me cheap but i have to know what i want to buy.

Thankyou for the help.

I bought it all stock from a man that had it for a couple of years and had bought it from the original owner. when the guy dropped it off it was driving some what good but not the way i test drove it. i put alot of new things in it, the list is:Radiator, water pump,fuel lines, fuel filter, plugs and wires, egr valve, pcv valve, jet and seat. i think thats it.

babymog you are correct the 603 at least starting in 1986 had sodium valves.

Quote out of the FSM:
"Due to the higher temperatures in combustion the chamber, the stem of the exhuast valve is chrome plated and filled with sodium."

Notice the typo?

Goowrangler the 603.961 that you want were imported into this country from 1986-1987. They were used in three cars, 300SDL, 300D, and in 1987 only the 300TD. Import numbers were pretty low, 12k+/- SDL's ect.

Good used 603's are hard to find and not cheap when found.
