How difficult would it be to swap in a 98/99 E300D turbo motor in a 95 E300D (non-turbo)? Would the engine bolt right up to the 95's 4 speed transmission?

I have some experience with engine swaps...a while back I installed a 1982 Porsche 3.0 engine into a 1969 911E.

You would need the entire wiring harness along with an ECM, as the engine fuel management is computer controlled. Don't remember if your's is still with the 100% mechanical IP pump w/o the electronic fuel actuator.

- The Finns have taken one of those turbo motors with a fully mechanical IP and make it run wonders.

- I still wish I could slap a turbo onto mine and have a wastegate control to boost to a safe level for my NA motor. But for such a low gain, would it be worth it?

I'm pretty sure the 95 E300 did NOT have computer control relative to the amount of fuel delivery and I'm pretty sure the 96 and on E300's did have computer control of fuel delivery in some manner.

This swap would also be complicated by transmission issues, the E300D turbos all used the 722.6 transmission and the drivetrain management software might be a bit confused if it was asked to operate in an environment where it was expected to coordinate activites with a 722.6 transmission that no longer existed.

It would be reasonable to assume that the turbo and non-turbo versions of the OM606 would share the same bellhousing interface but I don't have any first hand experiences with the issue.

Sounds like a fun project.

I do realize that the engine is controlled by the ECM. Wiring just requires patience But if it's too complicated it wouldn't be worth it.
Why couldn't the non-turbo OM606 engine be turbo charged?

In your case if you really wanted a turbo, best bet would be to buy 98/99 turbo rather than a swap or conversion. I suppose I could sell and buy one, but I think it would be "cool" to have W124 with the 98/99 turbo motor. It would be a sleeper

So the engine "talks" to the transmission? That is very interesting.

Perhaps I could get a 98/99 turbo motor and rely on mechanical fuel injection with modifications? Boost could be controlled manually with the wastegate. There is some wiring to the 95 E300D motor, but that is mostly for sensors and gauges, right?

I think that this project is very doable. The 98/99 cars are 7 and 8 years old now...certainly some of them have ended up in salvage yards with engines in tact.

Buy what you want. If you have to build a car, build a racecar.

Good idea, but that's not what I'm interested in.

If you have a car with a bad engine anyway, then I'll cut you some slack. Otherwise this is misguided energy.

I'd love to stick a turbo on mine, but there's no bloody room left in the engine bay!

Sometime take a peak at the turbo models...the turbo fits in their nicely on the left side.

I don't think it would fit on my right-hand drive car as the steering gear is in the way.
Doesn't the intercooler go under the radiator or something on the turbo 606's?

I know on the 617 engines, the internals (rods, bearings, etc) were much stronger, as well as the pistons being oil cooled, to handle the increased load the turbo puts on the motor. I am not sure if this is the same with the 606 motor, but I would strongly assume it is.

does anyone know if a 250 td was made with a 20v engine? I imagine that would be a good comprimise of economy and performance.

ditto on the above comment regarding many internal differences between factory turbo and non turbo. i have set the 617 turbo motor beside a non turbo and the differences while not readily apparent after looking and thinking are obvious everywhere. longer nose on the crank, bigger pulleys, double belts vs single, all the differences mentioned above and surely others. not to mention different intake exhaust manifolds, valves, air cleaners, wiring harness etc.

my advice is on that new of a car is to change the entire car if you want a turbo.... as someone already advised above.

i love a project too, but sometimes it just doesnt add up... money wise. it is very fun to think and talk though.

if doing a major project like this, it makes sense if you have blown motor (not turbo, broken) and want to make the change, then start with a second car, wrecked or with a burnt interior or such, as close to the same as yours and switch everything. this will eleminate as much as is possible fabrication of parts, and or buying every little thing.

You could do this as a Super Turbo like Mauri H. and set the 606 to use the mechanical fuel injection like the 603 and the 602 but I wouldnt consider this worth it unless you were going "the full monty"

When ever I think Im getting over my head, I reread this thread on the VW boards:

SVTWEB's Passat AWD V6 TDI 6 speed manual wagon

Start with V6 GAS Auto AWD Passat wagon in USA. Buy V6 TDI 6 speed manual AWD Passat wagon in Germany. Stir and mix, presto.
