Turbo charger

[webcay]

Hi Guys,

can you suggest a source for our KKK turbo charger.

i don’t need it yet but.....

[Einspritz]

sort of working on it.......

 

But am interested in what anyone has used for comparison.

BMW Classic has been talking about reproducing the KKK unit for a few years now. But still nothing. The Garrett unit seen in the pics here fits in the space and the car will run better than stock.

Can you please tell me the model / part number of the Garrett?

[frached]

I can get a better look if this does to help you but it looks like a/r 42? I think this may have been something they used on european escorts. Let me know if you need any other pic angles or info. thanks- Fares

[Einspritz]

thanks.

 

If you could find an ID plate on the compressor that would be helpful like this:

Could't find any plate. It only says A/R 42 8C1.

I think Byron knows which Garret works. One of his builds featured a Garret unit but had to fab adapter for manifold.

On a Garrett, the plate with the info should be in the middle of the bearing housing somewhere.  (where the oil inlet and outlet are).  I'm interested in what you have here.

I did find a T25 turbo that bolted directly to the exhaust manifold.  I had to machine an adaptor for the inlet on the compressor side so the stock 90 deg elbow to the air filter would fit. 

 

It had an internal waste gate and I had to modify the external actuator to make it fit.  I also had to fabricate a new down pipe as the outlet was completely different. His exhaust system was a total Frankenstein hack job anyway so I fabricated a complete stainless system (offset outlet)   

 

The car did not have a stock turbo when my customer bought it and we spent the better part of a year looking for one.  I finally decided to get something on it and get it drivable and keep looking.  I built a fresh stock engine and went through the rest of the drivetrain and the Turbo was our only reason it was not running.  I did not run any additional boost (still 0.5bar) but this new turbo spools up so fast we get 5 psi of boost at 2500 rpm.  This thing is a rocket ship!  It still runs out of breath above 6200 rpm but that is just fine, it pulls like a truck at 2000 rpm!  

 

I will have to go back and find the part number,  I believe it was from an Isuzu Diesel pickup. If I remember correctly it was about $450.   We never found a stock turbo and the car has been sold and I'm not sure where it is any longer.

This was the car that recently sold on BaT, no?

Yep, that’s the one.

This is how the Garrett looked on mine. More photos at Korman's Resto site.

I visited this post after "Intercooler." In it I ask in there an M10 turbo crate motor would be a commercial success. Preyupy, based upon your experience with the Garrett mod, do you think that could happen. The S14 is kinda the crown jewel of '02 conversions but they do not drive as well as a turbo motor in my experience. Based upon what you say about this motor you built and my experience with mine I think the achievable mod is the M10, efi, IC, turbo motor. What is your view? 

 

[Preyupy]

I think a modern Turbocharger with current EFI technology with an intercooler would be a great way to go.  I was involved with one of the first S14 engine swaps into a 2002 back in about 1990 and as much as I love that engine they have otter so expensive it has taken that out of the reasonable possibilities for me.  
 

With modern EFI and turbochargers you can easily get a reliable and driveable 300 hp on available pump fuel if you build the engine correctly AND tune it well.  I would sure do this before I went on the M20 transplant or even M42 swap.
