Hi guys so the K24 will need to be bored out to at least 87.25 from what I was told. I'm going to me making over 300+whp k24/k20 turbo setup under low boost for a some what of a daily car. I was told it would be pushing it if I was going to bore the stock k24a4 sleeves to 87.5mm with forced induction . Is it safe enough to do because I could not really locate a correct answer to my question after searching online. The other thing I'm thinking of doing is just picking up new TSX over sized 87.25mm pistons and new rods and calling it a day. CP can't make me the 87.25 pistons and not sure Wiseco can I'm waiting to hear back from them but I'm worried going 87.5mm with shelf piston is pushing unless I'm wrong.
