bearings are cheap you should replace as much as you can. honestly I wouldnt build the engine but buy a short block form Iag that should be fine. so here is the skinny on who boost works. you will make more power with more boost, so if you up the compression you cant run as much boost. I dont really think that the 20g will make much more than you are making now. change the turbo get the biggest turbine hosing you can and push that. also you are limited on your 1300 they wont make what you are looking for.
