I have a 2004 WRX wagon. It looks stock outside, but it's not... Performance modifications: EJ257 2.5l block with CP forged pistons Stock 2.0l heads SSAC Top mount intercooler Turbo-back exhaust Forced Performance 8cm 18g 750cc injectors Walbro 255lph fuel pump I need to get it retuned, but it dyno'd at 285whp on a mustang dyno. I asked for a very conservative tune - there's a LOT more power on the table with this setup. Others with similar setups dyno in the 330-350whp range. The one time I was able to get it to the track, I ran a email@example.com. With the mods I have and a more aggressive tune, it should be capable of a low-12/high 11 second pass and trap in the 115-120mph range. Any other subie owners out there?
