Ok so i bought an 04 sti thats knocking like the police. Paid 4000$. Many mods and upgrades. The story is dude blew it up and had a new short block put in by subaru and 4 days later its knocking. Local shop tore down for me to reveal spun main ( obviously ) also shavings throughout the whole thing (bottom end, and heads). So i bought a brand new bottom end a good used set of heads an oil pump and a 20g turbo(its what it had). So basically id like a list of other things i may need, things i shouldnt reuse and precautions to take before proceeding. Thanks.
