I really didn't know where to put this, so I figured single turbo would be fine. I'm browsing online with a friend who's looking for a turbo and we come across a turbo that's been colored red. We think it was anodized since the metal's texture looked intact. Does anyone know if this has any adverse effects on turbos with cooling or if the coloring can even last? It just seemed unusual so I thought I'd ask you guys.

Anodizing is really nothing more that Alodine with a coloring in it. Alodine is used to prevent corrosion in aluminum.... SO... no adverse affects at all... it will fade over time... and will scratch. But it won't cause anything bad to happen.

Most colored compressor housings are powdercoated.

Anodizing can cause a drastic reduction in fatiuge strength but for a front cover this shouldnt be a problem, it is also most likely not anodized as well as it dosnt tend to give great results on alot of casting alloys

I see, so it's more than likely powdercoated. Does that have any effects?

i used to powdercoat a bit a couple years ago. i have done a few valve covers and the powder coated valve covers seemed to run hotter then the stock coating. i dont think it would hurt anything and powdercoating is very durable so it should hold up

if the coating of the anodizing is too thick then the clearence between the turbine blades and the housing may be too tight.
