FAST 90/90 setup
42# SVO's on stock rails
255 walbro
ASP pulley
4" CAI setup
1-3/4" SW LT's with stepped down 2.5" collectors
2.5" ORY into single 4"... 4" bullet dumped at axle
6-speed with Textralia
HD chromemoly DS
9" with spool and 4.11's
NX kit

dyno'd the car tonight... previous bests were 485/445NA and 603/598 n2o.

520RWHP & 475RWTQ - motor

Holy crap! Although I'm sure the sound gives something away, that is still one hell of a sleeper. I know I've never come across a third gen with over 500 hp, nevermind a shot of nitrous on top of that. Get that thing to the track!

I think that statement only holds true if it still had the TPI. Thats on the same level of putting a LSX motor in a Miata and showing all Miatas whats up. (yes I did note the sarcasim but I still thought the LSX in the Miata is uber funny)

As for the #'s that is sick. If you never open the hood, I bet you would have some people scratching their heads when you blow their doors off.
