I just got a d16z6 block for free and im positive its sezied, you can rebuild them right? How do you tell whats wrong and how to test for problems, like cracks and things. I want to find out if i can rip it down and build it up, from the ground up then swap out my old used b7 block. but i don't know what to check for so i can start my new summer project. I am going to go with all after market parts, I want it to be very strong, I plan on boosting it with this turbo im getting from a friend who has a turbo mitsu Starion, and he has many parts laying around so i plan on making a custom kit for some low boost.
