Thanks guys, I have a 700km '09 engine that I'm going to do the race prep to. I just wanted to do the hard yards tuning etc on this old engine. Motors are all around $600 AU here but I found new pistons for 100 bucks the pair and rings for 13 bucks. The plan is to get some decent pistons and bowl them to lower the comp in the new engine. Just waiting for the bits and I'll be back into it
