I could be wrong but it just seems like this turbo with the setup I described would spool more quickly then the ball bearing turbo that comes with it or is the difference between spool times very minimal?

Also I found this turbo on SoundPerformance and was wondering what you thought

A water cooled turbo is more reliable, especially for extended hard driving like top speed runs and roadracing. Contrast that with a 10 second drag race where water-cooling the turbo doesn't do much good.

That's a 569.5rwhp turbo in your 1st link, and a 624.75rwhp turbo in the 2nd link. Neither is a 650rwhp turbo (through a 6spd), so neither one meets your power goal - right? Also, 624.75rwhp is right at the top of that 2nd one's capability range, probably running a lot of boost to get there. That boost level may be beyond your meth injection kit's ability to suppress detonation for. If you were willing to run race fuel, you could try that turbo at 40 or 50psi of boost, but with a limited flow meth injection kit, that won't work. Oh, and of course that 569.5rwhp will spool quicker, but so do the oem twins - right?
