Some people need the preaching. Obviously you still don't get it. You've made threads before about wanting to do your own sleeves, and we already told you why they don't get sold on their own. If you're so hell bent on going 2 liter and boost, get a B20 shortblock, build it in your spare time so the car isn't down, and put in a Golden Eagle blockguard. Then take a saturday and swap it in.
