W124 Superturbodiesel - The Ultimate Street Sleeper
Discussion
My daily shat its clutch recently. Mk 4 mondeo titanium x. And my mechanic was abroad on holiday. So the merc was promoted to daily duties! Its a little noisey, and no radio but hey - gets me to work.
On my ritual Sunday hoon i started smelling diesel through the vents. Opened up the bonnet to find my turbo side of the engine all wet. Took the plastic cover to find this
The injectors are fairly new so im certain its nothing major. Maybe a leak off pipe.
Rang my bro to borrow one of his motors. Fingers crossed for the supercharged rangey... but he was using that as his P1 is down a cylinder and his prodrive is not holding battery. So i got his Mrs' fiat 500. Yay! Its like an elephant riding a peanut...
On other news not much else. The mondeo failing has pushed back some work on the merc. I have started fabbing my center console piece for the vents though.

Just out of interest, how easy would it be to get, say, 200bhp out of an OM606? What sort of torque would such an engine make? Would it run cleanly and drive like a factory car? And how much would you need to change to give it certain reliability?
And if you had a NA OM606 in your 124, would you start with that or would you swap it out for a turbocharged motor?
Questions, questions, but I do appreciate what you're doing here.

Who was the chap who spotted me at Bourne Tesco then 
Reliabilty is not an issue for these motors. They will still do 500k at 177bhp or 500. Just dont over rev them. You can make decent power smoke free if you really need too.
Swap for a turbo unit.

They are 177 standard, so a cheap map would see 200.And if you had a NA OM606 in your 124, would you start with that or would you swap it out for a turbocharged motor?

Following on from my previous thread - which has had all of the photos removed (thanks photobucket!)

Hey OP,
I've been following your thread for a while- I love the car, I mean - I genuinely covet the car. I'm considering doing something similar with an estate C or E class of some description in the future - a usable sleeper and everyday drivability would be really nice.
Firstly, what do you need to do to get that sort of poke? Is it as simple as bolting a new turbo to a modified manifold and fiddling with the fueling or is it more complicated than that? Most of the cars I've seen with OM60X engines are 100k+ miles - do they tend to be fairly mechanically reliable?
I've seen that some of the tuning company's dyno graphs tend to be quite peaky in terms of power delivery, so I'm a little concerned how it would handle daily duties. Is it a realistic daily prospect or is that pie in the sky? Is 40mpg realistc or is that to be taken with a pinch of salt?
Given your experience of running your car, what advice would you give to a newbie?

It is literally just that. Converting the car from edc to manual pump as well. However if its just a daily driver with poke you need a massive cc pump.

You can get mid 300 wheel hp from smallish turbos. Which provide much better driveability than my oversized one - i just love the grin factor of mine - and its running extremely conservative fuel wise. They are called a million mile engine for a reason - incredibly robust and love boost. If your using boost 30 id say is easy to achieve. Anything over is a bonus.

Glad to see it back here.

That was me. Great to see the car, makes a change from the usual s
te that I see in Bourne 
Collected the car today from DPUK!
I was the first customer for their 'anti jerk kit'
My car has always had really bad diesel jerk. Its the only achilles heel in the superturbodiesel world; a major drawback - it drives like garbage at slow speeds.
It basically doesnt like small throttle movements in lower gears, and to stop a jerk you either need to clutch in, or apply a blob more throttle. It makes it a ball ache to drive around towns or in traffic.
Ive become so used to avoiding the jerk that in reality im the only person who could drive it. It was even jerking on the dyno when it arrived to dpuk!
Speaking of the dyno... i did have a mild pump tune as well. This pump is capable of far more than the engine can handle. So it was only tweaked a little:
Im quite happy with 400whp!
On the road it feels mega. The gears are much longer with a few extra revs so it can really open up that turbo. It pulls extremely hard now, and second gear has some kick too. The comedy smoke has also mostly gone. Under heavy load in 5th or 6th its as clean as a whistle. Only emits a big chug just before the turbo gulps.
I also had a good nosey at their demo car. A project that was built in 8 days for roadkill at northampton. The Vin Diesel (yes... its a diesel charger....)
