I'm installing a LoveFab turbo kit in a RHD S and there are a few heat concerns. The turbine housing and downpipe are close to the brake and clutch hydraulics and I need to do everything possible to shield them. I will be using aluminium heat shields but I'm also considering have the manifold, downpipe and turbine housing ceramic coated.

Do these coatings make a significant difference?

Is there a problem with coating surfaces like the inside of the turbine housing or the V-band flanges?

 

You may want to check with Garrett on coating the inside of the turbine housing, not sure if any coating can stand the heat inside the housing.

I've seen some pretty nasty heat damage from a turbo, melted wiring, cooked paint ansd seam sealer.

The Jet hot coatings I've dealt with on American V8 cars makes a pretty noticeable difference in under hood temps.

Here's some underhood fiberglass insulation for a Speedcraft car (low mounted turbo) The OEM heatsheild was covered on both sides, and makes quite a difference in temps on both side of the sheild.

 

I had Jet Hot coating on my manifold on my Civic. It blocked the heat well but it flaked off after a year. I plan on trying Swain Tech coatings for the S.

 

I've run ceramic coatings on V8 headers before. They work as advertised. I bought a cheap set and the coating flaked off; I bought an expensive set and it's still good a year later. I know turbo's run hotter. I'm not sure how well it would work for you.

 

I had my first turbo kit swain tech coated but never actually ran it. I am however trying to sell it if someone is interested (sorry couldnt resist)

 

I am having it coated by Competition Coatings. I rang around and every exhaust/turbo shop referred me to them. It is a shiny silver finish and quite durable.
