not sure, my engine build comes with coated rotors, oil pump and bearings. I did pay extra to get the turbo, dp and rotor housings coated. www.Turblown.net can get you pricing info.

Thanks for the heads up, I've researched a bit on coating, and found that this Polydyn coating was the best route.
Polydyn Performance Engine Coatings are applied so that a .0002" to .0007" overbuild remains on the surface, but there's a lot more to these coatings than meets the eye. PolyDyn fluoropolymers actually become a part of the coated materials surface; .005" t 0.50" actual penetration depending on the material. While some overbuild can be removed, it is virtually impossible to extract a polymer from the pores of the metal to which it is applied. Consequently, PolyDyn coatings will last almost indefinitely.
