Okay people, who has a B20vtec setup with stock block internals, what RPM do you rev 2, and how long did it last you. Give me details of your set up. I want to do one but have no money to change the sleeves. The only thing I might be able to change is mabey the pistons, or if not that, the rod bolts, but if I find out I can do it with stock block interals I will. Give me some info on this.
