Answer 1

You are basically going to have to redo the entire block from the ground up. New pistons, rings, valves, port the heads, different cams...It will be a full motor tear down, anything that is weak and will have stress put on it will need to be upgraded. Plus that block is not really meant to even have a turbo since the compression wasn't built for it. The problems wont stop at the engine they will continue thru the drive train, including broken driveshaft, axels etc...I would just recommend either running the boost you are now and get it tuned. Or just save up for a new car that you are able to run that high of boost.
