lol man sorry, I was just busting your chops... I will be limited by my turbo, which is the AVO 320 GT25 (or GT28?) I believe (From the 2.5 RS kit). I will be leaving the heads bone stock but serviceable, except for new valve seals and resurface... I have been looking for the cams from an EJ20G/EJ20K, but not sure if the difference in power will be worth the money spent. I will be keeping the 6500 RPM limit, the GT25/28 turbo, the oem 2004 WRX TMIC, and the stock MAF. My exhaust is currently made up of an oem single port manifold to turbo (to be replaced with the borla rep dual port header), 2.5" downpipe to an oem 2004 WRX cat, to an ebay 3" catback, to a 2.25" reducer at the axle, to an oem 2005 STi axle back. My concern is that I dont truly have the flow on the exhaust side to let any cam really sing in the top end. Combined with my smallish turbo, and the WRX TMIC, and the low redline, this car is going to be more of a torque monster than it already is...

See where Im coming from with my question?
