New STS owner :) Just got my car back from F-Body Central yesterday...
Car mods (2002 Firehawk TA M6):
Jet-Hot LT's
Custom oval Y-Pipe
GT76 STS
FMIC from Texas Rear Turbo's (Billy is the man, great customer support)
42# injectors
918 springs
Requisite Gauges
Power Steering Pulley
MSD wires and NGK-TR6 plugs
4:10's
Tune by FBC
490/450 on the dyno at Heffner's Performance (the Viper tuner) with 7# of boost. It's still on the stock fuel pump until next week (we ordered the wrong one).
Not bad, A/F stays between @ 11.5 or so and @ 12.1. Runs like stock until 3k RPM, which is good since it's a daily driver

LOL, Thanks kjmdrumz You must be the guy Jason was talking about, he mentioned he had someone come to see the car and they were savin'. I recommend it I'd also call Billy at Texas Rear Turbo (or PM him from here, trtturbo) - He's a great guy and knows his stuff about the STS!
Ole: From what I understand (just reading around the forums) the STS is probably a little louder than a traditional turbo kit since it's under the back of the car and not enclosed in the engine bay... ?? I'm sure if I'm wrong someone will step in But yeah, it's starts off as a little "shhh" at @ 3k, and by 4k it's screaming like a banshee.

Great numbers

Yup, rear end needs to be done first - stock with whining 4:10's
After that, probably forged internals and a boost friendly head/cam package
