good VNT upgrade for a K14
I had a OM613 Turbo Gt2359V on my 605 with selfmade arduino controller. Worked very nice but the vanes had the tendency to stick. I cleaned them once, but the problem appeared again after a few thousand kilometers. Problem is, my wife drives the car and she drives too slow. The vanes get full of soot and never burn free. So I switched back to K14.
The Turbo itself is a great choice for the engine. It spools immediately even without any load and I was able to max out the 6mm electronic IP with it. Mounting it was a bit tricky, had to make adapters for the stock manifold to turbine inlet and compressor outlet. Also I had to turn the hot side of the turbo, which is tricky because of the vnt mechanism...
