Car: 13 STI hatch. Pertinent Modifications: stock turbo, id1000, flex fuel... Description of the problem: knock knock, who is it? Recent maintenence or modifications: Nope Ok, now thats out of the way... Connecting rod failure in the STI today. Found a short block built by Jay at real ST Performance. It has 10k on the sb itself with Manley rods, ARP headstuds and weisco pistons. I'm getting it for what sounds like a decent deal from someone I know. SO the point of this thread is to fill in some of the knowledge gaps. Edit: Was told it was a "05 sti ej257". When I looked up head gaskets, I see some listed with and without dual AVCS. Since mine has dual, I assumed I would get those head gaskets, but didn't know if the 2008+ 257 has additional oil passages. I would assume not, but its worth asking... Edit 2: Found the answer, no differences in the casing, just the heads. Ill end up getting the correct gaskets, just not sure which ones yet. I wasn't sure if I should go with an OEM turbo head gasket (Amazon has them listed for $35 each) or if I should look at installing cosworth gaskets instead. Mind you I am still stock turbo and don't plan to upgrade unless there is an issue with my current one. I would assume the gaskets would be better done now so the block isn't disassembled down the road, but I am trying to keep the costs down as I still have a house to put back together. I am planning to also pickup a gates timing belt kit. The Advance Auto I work at only sells dayco, but I don't think they are as good of quality as gates from what people have said. Also planning to have the heads resurfaced while they are off the car. Besides belts, plugs, and maybe valve cover gaskets, is there any other items I should consider? Edit 3: any value in an upgraded oil pickup or cooler while I have it disassembled? Edit 4: Thinking about redoing the clutch, since the chassis has 50k, but that isn't really in the budget. Thoughts?
