I recently purchased a complete bolt on turbo kit for my 09 1.8l vibe. I've had it for over a month, and have had no problems. Has given me great gains, and have no complaints about it. It is reasonably priced and can be installed in 1-2 days, of steady work. If anyone is interested in it here is the link...........

The entire turbokits.com staff was really nice and helped me out with all my questions.
Their is also another guy on the matrix forums (not sure if anyone is a member there) who has done it.
