People have saying that the price of STI shortblocks new from Subaru has gone up dramatically. Everytime I say you can prolly find one for under $2k I am told nicely that I don't know what I'm talking about. Since I'm curious, I went looking and the first place I thought of has them listed for $1689. I bet shipping would be around $100. I don't need one or anything, but I bet I will someday.
