If its an all out race motor with fuel regulations and that sort of thing I think coatings have a place. Other than that I think it's a waist of money. Every used piston I've seen that was coated had the coating worn off in some way shape or form. At that point what good is it?

FWIW, some added info. I have been told that coating the exhaust valves alone is worth 5 hp but like above said the coatings will wear off at some point in time. David Vizard has a lot experience with coatings and he has recommended Calico for the past x amount years.

I coated the combustion chambers, valves and pistons (Thermal on dome, lubricating on skirts) on a 2.4L Turbo 4 when I built it. I have not had the motor back apart but it does make 450HP. For the extra cost, I would do it again, I also had the head, block, oil pan, trans case, etc... powder coated, and the turbo, manifolds, and plumbing ceramic coated, the motor still looks like new 30K miles later.
