Start with dryfilm coatings. We apply these to almost all our pistons:
* oil retaining film applied to piston skirts -- increases oil retention, so reduced friction and wear
Similar to coatings for the engine bearings -- retain the oil, reduce the friction, and it all lasts longer.
* oil shedding on underside of piston -- increases oil runoff, so helps carry heat away and cool the piston, reduces reciprocating weight (in theory, anyway)

Then consider thermal barrier coatings:
* piston domes
* heads' combustion chambers, faces of valves, back side of exhaust valve, exhaust port
Reduce heat transfer to the piston and head, put more of that heat energy to work driving the turbocharger.
DO NOT thermal barrier coat the pistons without coating the heads, too.



After that, you can really start spending a lot on coating the valve stems, doing the valve springs, exhaust and turbine housing, heat-dissipating coatings on the oil coolers...

Thanks Chris!

I will look into these and probably pull the trigger for many of these coatings when I get up the funds and start the rebuild process on my engine.
