2009 Subaru Impreza WRX Premium

This is my 09 WRX GE build, I've had it for six years now. I got it from a dealership instead of third party so I definitely overpaid. The original motor blew due to a spun bearing and currently in it is a JDM EJ205. There are some things that I wish I knew before going headfirst into this build. Thank NASIOC for everything.
