Hi I'm Will. I have a silver 2000 Miata. I just rebuilt the engine, supertech 8.5:1 pistons and eagle rods for an eventual turbo, probably an EFR 6258. Currently having some issues with knocking noises from the head after the rebuild. I'm assuming it is from straight weight oil being used in the cold, but haven't had the time to look into yet. Looking forward to getting it back running and getting down to Road Atlanta.
