There's a guy in Salt Lake City who builds some truly nasty 4cyl Japanese cars. He does the turbos and intercoolers, don't know about the engines. Not necessarily junker looking, and those things are fast. Race one of them and it'll clean your clock. His own car is a 4wd Eagle (?) which I saw during turbo fitment many months ago - completely built 4cyl 1,000hp monster. There are some very fast innocent looking ricers tooling around Salt Lake area.
