Automotive Alusil block piston coating solution request

+++

I am looking for a piston coating solution that will allow me to run forged aluminum pistons in my Alusil block Porsche 928. Only cast aluminum pistons (iron/tin plated) are available. Cast piston strength does not meet my needs. I must have custom forged aluminum pistons manufactured for this application.

Solution must be durable (current cast aluminum pistons with iron/tin plating typically last several hundred thousand miles of service with proper engine maintenance).

Does anyone know of a ceramic coating solution, if so, where I can purchase it?

(I understand that the iron/tin plating process is not appropriate with forged aluminum pistons.)

I'm curious to see what ceramic options are available. But correct me if I'm wrong but doesn't the 944 turbo utilize forged pistons with the factory "Tin" coating?
