I'm sure if you pull the head you'll see what else you need to buy. Had that happen to me and the piston kissed a few valves. It's better to see what exactly needs to be replaced before you start researching. Might find yourself looking for the wrong thing. A 4g63 dohc turbo setup ain't that much more then a complete rebuild a second time around. Keep your options open. Btw, mine had a con rod cap bolt failure from oil starvation to my first 4g63 DOHC turbo motor. No scar to cylinder walls, massive damage to crank and brace.
