That motor is not meant for a turbo at all. Poor vehicle choice for such an undertaking. You don't get more power out of a diesel by just turbocharging it, you also need to supply more fuel and air etc, which increases temps, and then melts the engine, since it was never designed to have a turbo.

I'd choose another car. Why would you want to wreck a classic diesel like that

Even the turbo Mercedes models from the 80's only run at around 11-13psi of boost, and those engines are specially reinforced and modified to take the additional stress of such operation.

Agreed. If you want boost, buy a 5.9L Cummins....

He only posted once and hasn't been back, maybe we scared him away and he'll sell the poor 190 to someone that appreciates it for what it is....and then he can go wreck another car.

Keep the boost under 5psi and it might survive a decent time. Put it under 30psi and I seriously doubt it would live out the day the turbo is put on.

All that is IF you can get a turbo that big to spin up at all on such a small engine.

That's a valid idea.

In many small airplanes the use of a turbo normalizer (increase manifold pressure only to 14.7 psi absolute, regardless of altitude) works quite well, provided the turbo is a good match for the motor.

If he lived in Denver that would be fine, but there is no need or point to use such a large turbo.

I'm going to put this on my 617:

I have a 87 300 sdl how much boost does this put out normally? How much can it handle safely without breaking anything? (it is a daily driver)

It normally puts out about 12-14psi, and thats ALL it NEEDS. Increasing boost does not mean more power, it means damaging the engine. You only get more power by increasing both the boost AND fuel, increasing the fuel is difficult and complex, not to mention you'd probably melt and destroy the engine. Leave the poor engine alone, the engineers at MB already designed it for optimum operation. It will run a long time reliably without such modifications. If you want more power buy a sports car.

There, thats my rant.

Google will tell you how to adjust your Garrett or KKK turbo. KKK is way easier.

Either. From 1981 on it could be a Garrett or KKK turbo, it depends on which MB had in stock when your engine was assembled. The Garrett is by far the most common but I've seen at least one KKK turbo on every model until the 98-99 E300 when they used only the KKK K14.
