Also, this is usually a hotly debated topic..

Porsche does in fact use coatings on some of its production engines.... oddly just the exhaust ports...not anything within the combustion chamber...I was told that the thermal barrier in the combustion chamber played havoc with combustion temps.

I for one cant see anything wrong with keeping any heat from being absorbed by the piston dome , or cylinder head. Kinda like everytime that exhaust valve opens its like a big flush.. all the heat goes out!!

Allthough wierd things may happen if all that heat isnt allowed into the engine, will will the heads seal properly?

I wish there was more empirical data to support the claims of the manufacturers...

Coating the pistons,valves,head, header probably can be done fo about $1000. Thats a small percentage of the cost of a A+ rebuild..

My 911 project is almost done. When I get it fired up, Im going to pull the 3.2 from my 914 and build it into a turbo engine, and I will be using coatings on most everything.
