Could help a Suby Newbie? I am building a 2004 WRX. I'm using a 2.5L short block, STI crank, STI rods, CP 8.5:1 pistons built by Steve Johnson at SSperformance in CA. I will be using the 2.0L heads and stock cams per Steves advice. I'm having a hard time picking a turbo. I've used the VF22 on a previous car (2002 WRX w/stock motor). What do you think of the godspeed products? Can you offer an advice?
