Welcome to the forum
Thank you!
Interior is black with white ceiling(roof)?
Engine has new pistons, bigger turbo and 6mm pump elements with intercooler.
On the videoclip I used an old om617 kkk turbo with upgraded compressor wheel.
Now it looks like this:

What turbo did you put in after the KKK broke?
Do you have any photos of the intercooler pipe routing?
Still driving it? Anything you would change?
Thanks again.

Thanks for replying
Now im using a borgwarner s200g and a dieselmeken 7.5mm pump
Im driving it everyday to work
If I would change something..... I would like to have a 5 speed getrag 717.400 and use a 3.07 differential. ( Currently 4 speed and 2.47)
Also im not sure what to think of the clutchkit I got from clutchnet or whatever their name was. Maybe a bigger/stronger clutch, not sure.
The intercooler has the connections on the same side, so the piping is as easy as it can be. Old picture here.

Having some trouble with vibrations while driving. Thought that it might be the exhaust getting contact with the chassie.

I think it runs pretty well too
Currently im boosting 1.8 bar aprox. Thinking I can go higher, but as for now it's 1.8Bar
Boost starts to build around 1800-1900 rpm.

Very nice engine....clean too, which is a rarity. Polish the valve cover yourself?
With the 912 I used a 6mm pump giving 117cc
I broke the turbo one day when driving uphill for around 200km/h without wastegate. My boost gauge only measured 2 bar, but it was maxed out so it probably was 2.5 or more Idk.
It broke anyway
Also it pressed out water from the radiator evacuation when pushing it too hard for a while. Had no expansion tank like the Turbodiesel has.But I drove it daily for 2 years charging 2 bar without any problems besides water loss. It was that one crazy uphill trip that did the trick
Thanks.
I polished it myself, about to the the same thing with another one these days before new year. (my brothers

I wish I had the answer on that question.
Only know that this one comes of an Deutz industrial engine 6.06L and 210hp
Turbinehousing is A/R 0.64
More than that I do not know. If I ever take the turbo off I will measure some.

That's pretty damn good considering. I'm worried about bending the rods on mine when I get around to running it. Consensus is to not go over 2 bar with the .95x engines or the rods bend, so very interesting to see yours didn't in the NA engine! All to do with fuel + RPM I suppose. I'll have to keep an eye on temps when pushing it too
As much as I like the look, both my engines have scratches on the covers so not going to be worth it for me

But I don't know who figured out this magical number of 2 bar boost to be the limit on these old engines
How deep are the scratches? The covers come with alot of marks from factory, can be grinded away =)
A friend of mine has been running a .952 engine with a 7mm pump, No idea about the CC it gives. But his ballbearing garret turbo (no idea about size) has been feeding that engine 2.1 or 2.2 bar for several years without problems. But then again, fuel and rpm matters aswell as you say.

Maybe 2 bar is the "can never go wrong" max
Scratches aren't too bad. I'm just too lazy to spend ages on getting them out and making it look nice when the rest of my engine bay looks like crap lol
Might look into it when I get my other car going after I rebuild my .952 engine though

Rather interesting about that Garrett, as apparently they don't like heaps of boost? I was looking at a small ball bearing one but were out of my budget range...

Over 90kmh in second gear with a 3.07 diff ?? I was quite surprised
Assuming 195/65 R15 wheels that gives a rolling diameter of 1.96m, 100 000 m/h/1.96 / 60 min = 850 revs/ min
850 * 3.07(diff) * 2.22(2nd gear) = 5793 rpm/100kmh
Either my calcs are off, your speed or rev counter is off or you have 15% bigger wheels or a 2.65 diff

Assuming 195/65 R15 wheels that gives a rolling diameter of 1.96m, 100 000 m/h/1.96 / 60 min = 850 revs/ min
850 * 3.07(diff) * 2.22(2nd gear) = 5793 rpm/100kmh
Either my calcs are off, your speed or rev counter is off or you have 15% bigger wheels or a 2.65 diff
Im using 225/50R16 amg penta wheels.
The speedometer is from an S123 tdt wich fits to 3.07
The rear end comes of and R107 and is 3.06
So now you can calculate properly to see how much it's off.

Over 90kmh in second gear with a 3.07 diff ?? I was quite surprised

If i were you i would test it with gps
Well 225/50 R16 have 1.98m diameter so not enough for 15% error. And you would probably notice going 15% faster if you actually had a 2.65 diff or your speedo was off but you didn't know it. So most likely your rev counter shows less than actual rpm.

I will test with gps! Updating when I've done it.

Comp wheel 54/77
Turbine 56/70
Twin scroll T3, not sure on size, maybe 10cm?
The compressor housing is huge!
This is the one stamped "EC-2", I have seen an EC1 as well but don't know how it differs. That may be the 7.14L version
I just got the same turbo, specs are

Increased boost to 2 bar. Guess I need to go higher, seems like it is still smoking when fully boosted while in 2nd gear.
