I expect I'll be using some sort of turbo insulation wrap on my set-up, but have heard of businesses that tear down turbos and coat the hot bits with ceramic. It's supposed to help with keeping the heat in the unit (helping a little with power) as well as increase the life of the unit.

i thought you should only ceramic coat Naturally aspirated (NA) engines exhausts to keep it warm, as the turbo gets too hot so ideally you dont want a lot of heat?

The compturbo turbo i have here is coated. Will not be able to let you know how it performs in a while though |

No, the coating is fine for use on turbo engines and turbos, it keeps the heat energy in the manifold (where you want it) and the heat out of the engine bay (where you don't)

Am I right is saying exhaust wrap and a turbo blanket would do the same job? If something is worth doing, it's worth doing half of. |

The turbo blankets look quite large for the t3 turbo is there enough clearance to fit one in a mini? |

Ah right. I understand now. I guess I'll heat wrap my manifold then. Thank you |

With a blanket/wrap, you have no insulation for the internal bits. So, they get full 'benefit' of high heat and moisture (i.e., not good). Blankets and wrap can also hold moisture against external metal parts, hastening their decline. I look forward to hearing about your experiences, miniminor63. **************************************

As the turbo and manifold (hence blanket/wrap) are at several hundred degrees at engine shutdown and under a bonnet where does the moisture come from?

How about polishing the turbine internals ?
Rusty by nature

I have several cars and a quad with wrapped exhausts and no matter how wet they get while driving they are bone dry once the engine is cool. Unless it is then made wet again somehow it will remain dry. Moisture is a natural byproduct of combustion, so internals are subjected to it. Any moisture that gets past the wrap/blanket will turn to steam upon contact, but that steam can be held against the metal longer than having nothing over it (like holding a towel over your head as you steam your sinuses). It wouldn't be a long period of exposure, to be sure, but it's longer than ceramic coating (no exposure where coated) or bare metal. **************************************
