Well, I'm sure it did, it was built by a very reputable shop for a member on here. When she decided to get out of the Subaru game, she decided to sell the engine. I bought it from her after it had sat for a long time but with very low mileage. I got it assembled, ready to drop in, minus build sheet. I had my shop check it for any apparent issues, but I didn't have them measure everything. I don't know the exact original mileage on the engine, but is was in the 1000-2000 range, which is break-in. We followed the break-in again after installing it in my car, just to be safe. Went to get it tuned after ~1500 miles. Went to have it tuned, mechanic noticed noise from bottom end, checked oil and found it metallic, dropped the oil pan, spun bearing. Annnnd that was my weekend. Anyway, I'm (as you can guess) not entirely up to snuff on my engine mechanics, but from what I'm told, it wasn't in spec and I'm included to believe him given his motorsports pedigree and track record. Also, he didn't build the engine, so I can't really blow up at him, not his fault. As much as I would love to not rebuild it, I feel better knowing the person doing it this time around, plus if it breaks, he owns it. While the engine is out well be doing the following:
-Port & Polish Heads
-Upgraded Oil Pump
I'm also going to have the entire oil system flushed and cleaned and the turbo inspected. There are also plans for ceramic coating and maybe some EL headers. Hopefully we'll hit that 400 WHP mark.
