The turbo is a mix of the original exhaust housing and the rest is from a BMW 530d. I had to have the exhaust housing machined to accept the larger turbine. I'll get some more technical details when I've got a min.
So far the boost spikes at 2 bar before the ecu backs it off to 1.5 to 1.7. It drives more like a petrol engine than a diesel, it pulls all the way to the red line.
The only issue with a larger turbo is the lag. I get only 0.5 - .75 bar between 1000 and 2250 rpm. Then it goes nuts.
A remap is in order when I get the issue sorted out.
