How the hell do you manage to keep it that clean? I have just spotted the turbo, even the exhaust housing and manifold is bright silver, is it painted? If so what with?
I'm suprised you haven't gone for a stainless steel heatsheild.
Never seen such a good looking engine bay. 
Hey Ash, best way to keep it clean is hire someone to do it for you!
with the turbo... the part that you can see thats not under the heatshield is properly polished metal (not painted) I zoomed in a bit to show u..
I tried polishing up the part of the housing under the heatshield but its not the same metal finish and like a rough surface. So I just thought I'd use some extreme high temp alloy paint, and its hung on! I thought it would flake off soon as the turbo got some action.. it has stayed bright silver... so happy with that. I dont like using paint tho, the gearbox is properly polished up also. But where the manifold connects to the turbo that has high temp silver on it as well.. as I couldnt get to that any other way.
Hope this helps..
