A few months ago, "Turbo" magazine did a feature on several forced induction kits for various cars. They have a project 2k Max SE. I think it had an HKS exhaust and the stillen SC and maybe some other stuff...anyway, they claimed to have dynoed it at 282HP at the wheels. I haven't read anything about it lately, and they haven't put any updates on their web site. Go to http://www.gr8ride.com to see what they have done. Just search the site for "maxima" to get started.
