Holy Humongous Sig Batman!
With mods in sig I dyno'd at 257 rwhp and 297 rwtq. Taking into account ~18% drivetrain loss that puts you smack at 300 crank HP. Each car responds a bit differently to mods but a good place to start is: 75mm TB/Plenum, Midpipe/catback, CAI, UDP's and most importantly a dyno tune.
As for the juice, most wet kits are pretty safe. Some say 75 others say 100 and still others 150 is safe on the stock internals. People that run 100 shots usually don't have an issue, but most get a nitrous tune for added safety. Only thing you have to worry about is using a window switch so you don't get into a nitrous back-fire or over-rev situation.

I made 256 WHP with full boltons and no tune (stock computer) on a dynojet 248c that had a tendancy to read either right on or low....
Thats about 300 flywheel horsepower. its not that hard to get there guys...

RE: mods to make 300 hp
From what I hear long-tubes are a no-no in California, and in all honesty I think the money spent on long tubes and the install is better spent on other things unless you are looking to be pushing 400+ at the wheels.
