I don't want to sound like i'm bashing but how many 1000hp subarus do you see. The 4g63 is a beast of a motor stock. With mods and a good tune your talking serious hp and tq from us. I have a feeling that your problem lies in your tune. I know wrx's and sti's making way more power with your current mods. No matter what car if its not tuned correctly you can have the biggest turbo and you'll make shit for power. Good luck.
