I'm currently in the process of setting up my car for turbo and upon my parts ordering and everything I've had a flaw. I've ordered some pistons from diamond to have them double coated I've waited a month and a half for them to come in to see they we're not double coated. Do I return them and get what I paid for or do I ask to get my money deducted from the bill for the double coating process and run what they sent me. How big of a deal is the double coating? I don't plan on pushing the new motor to the edge of its limits but I'd like it to last. My goal was for a reliable 700-800hp set up and call it a day, will the pistons still last and not give me any issues? I don't wanna finish my motor and 2 years down the road a piston decides to burn up because it didnt have the coating. I know understand there is alot of variable, between the tune, fuel choice etc.... I just would like some opinions. My plan is to run 93 as I'm not too interested in e85 and turning into a chemist at gas stations playing with test tubes. Thanks in advance!
