Dipping a toe in the rabbit hole...

OP - I was in a very similar situation - a 'minimal' boosted build... i.e. what is the most bang/buck that will also remain relatively reliable for a street-only car.

I ended up going with:
Turbo kit
Small pump upgrade (255lph but if I did it all over again I would do 340lph)
small injector upgrade (600cc but id I did it all over again I'd go bigger!)
Clutch/Flywheel (would only do the clutch if I did it again, flywheel too chatty on the street for me)
Ecutek tune from a KNOWN GOOD TUNER (this is the most important part of any build)

This netted me 520whp and has been reliable for 20k miles. If you do decide to go SC instead, keep in mind the level of 'safe power' (if you can call it that) at the wheels will go down since the SC itself will siphon off several ponies on its own.

Also - unless in Cali, don't buy the Stillen SC - It appears to be designed for CARB certification and definitely not for reliability or power. Topz kit is what the Stillen kit should have been.
