First post so please forgive me for any missteps I make.
I recently purchased the following car with the mods listed:
2012 WRX Sti (15,000 miles on it)
Supersize Down-mounted ETS Intercooler Kit
TOMEI Exhaust Headers
SAMCO Sport Hoses
Light Weight Crank Pulley
H&R Adjustable Coil Over Kit
SPI Exhaust System
DC Power Engineering Alternator
Cobb SF Intake System
Perrin Strut Bar
Crawford Performance Air Oil Catch Tank
TurboXS Blow of Valve
Injector Dynamics (injectors)
Invidia High Performance Downpipe Exhaust
Garrett Turbo with Polished Hosing (Part Number: PCM 65223 706451-5005S)
Cobb 3 Port Boost Control Solenoid
Stage 3 Clutch Kit (not sure manufacturer on this as of yet)
Perrin Control Arm Bushings
KOYO Aluminum Radiator

Note that in the ebay posting it shows what the car looks like before the wreck and after. I have already performed all work to get the car looking just as it did when it's new (including stuff like alignment). I have also attached a picture to this thread of what the car looks like now.
What I'm looking for is everyone's opinion on what parts are good/bad on this build. Additionally I'm looking to see if I can keep some good reliability after getting a built short block for the car. My local tuning shop says if I spend about $6,000-$7,000 on a short block build that I could push my car close to 600HP. I don't imagine at that HP I would get any long term reliability out of the car. So I'm trying to find out if I did spend the money to get a built short block what HP level could I obtain while still keeping some level of reliability from the car. Lastly any suggestions on other upgrades you think may help my build (the more specific the better).
Thanks for any input you have.
