You're not paying for the power number. He said in the description that kit can produce over 600awhp.

Think about it....a 440awhp STi would actually be quicker than a 600awhp STi. Why? Spool-up time. A GT35R on the 600awhp STi won't spool up to around 5krpm, whereas the other would spool almost instantaneous and take off like a bat out of hell.

Also, who would dominate on a track? Monster spool-up time? Don't think so......

So you want something fast for cheap. Get an SRT-4.
