er... you know you'll need to spend hundreds of dollars getting things xrayed and tested and so forth anyway? And your block will probably need to be bored if it's broken... so the stock pistons won't fit anymore either.
You'll need a rebuild kit just for the seals and such if nothing else!
if ya doin that just to get things running and stockish, find a GGSR N/A 4g63 engine..... the entire bottom end shouldnt cost you much.... or turbo the entire engine......
