What car are you going to put it in. Have you thought about a USMD STI 2.5 or a JDM Forester STI 2.5 (same as USDM STI). You can find a lot for sale on NASIOC in the vendor forum. There are many companies selling built engines as well. I would suggest looking into a short block with cp pistons if you plan on 350whp or more. I swapped a JDM forester STI 2.5 in my WRX and will be getting a built short block after my tranny arrives. I wish I would have gotten a built engine the first time. I recommend Worldone Performance. They are a vendors on all of the subaru and evo forums.info on Worldone Built engines There are several companies that build Subaru engines. I would do as much research as possible before you decide.
