*MELLO*SOS* · 04-03-2006, 05:28 PM

I want to have my HKS cast bottom-mount manifold for my RB ceramic coated. What are your opinions on having both the inside and outside coated vs just doing the outside?

Some people have said that doing the inside isn't suggested or common because the ceramic could "flake" or otherwise come off and go into the turbine. I've never heard of this, but a few different people have mentioned it.

Others I speak with say that it's common to do both the inside and the outside. I think this would offer twice the thermal barrier as just doing the outside. This would result in the exhaust gas retaining more energy and the engine bay being cooler. I also plan on having the turbine housing coated, but again I'm unsure if I should just have the outside done or inside + outside.

Please share your thoughts, opinions and experiences with ceramic coating (cast) turbo manifolds and/or turbine housings.
