HELP! Engine blew :(

I'm in the exact same boat. I have an 04 Sti completely stock that just threw a rod bearing. Sad thing is it only has 86,000 miles on it. I am just going to go with an oem block. The big thing I'm wondering about is an 10103AC050 vs 10103AC030. I read that either will work but the AC050 has a nitride crank. Which one should I order? Also, What is the deal with the 704 casting? Any advice would help. I figured it would be applicable to the op because they have the same problem

I bought a new exhaust housing for my turbo for $100. I didnt have money to upgrade it right now. Is that going to last me? My old one was cracked but the turbo was fine. No shaft play or anything.

try reposting that to a new thread.

I thought the motors were pretty interchangeable though.
