I have an F23a1 that is turbocharged, I just ordered my custom pistons and the guy I spoke to teaches classes about building hondas so I assume he is smart when it comes to building honda's. He told me that I should go +0.020 bore since I lowered my compression but he says that this is still safe for the stock sleeve so it doesn't become too thin, what do you think, I can change my specs if I change them in the next few days. I am only going to run like 12-14 psi, and I have an AEM EMS so it will be tuned very well. What do you all think.
