This is a picture from my recent engine, don't be afraid, it will not stay that messy, This is taken at the same day I got it working:

Turbo is Holset HX40, intercooler is big enough:

Exchaust manifold is specially made for that turbo:

The car has two H&M:s biggest oil coolers, one for engine and one for transmission (722.3, reinforced to be much stronger than in W140 600 SE, turbine made to stall speed 3000):

Those videos about my car are taken from last summer, I was suffering some technical problems with boost leak and the fact that exchaus manifold was loose all the time, stud bolts from the cylinder head were coming out. This made the car hard to drive in the start, it was difficult to get the boost up before first 100 meters. 60 ft times was worst ever (2.6 - 2.9 seconds). Of course the street tires are not too good on glued track.
With this new engine I expect much better times, output should be around 500 hp and 800 Nm, that is the target.
