That car has potential, I watched the video again today and man if he had slick, more boost, and spray I dont know many that would touch him. I loved the overall car it is very clean, great stereo and the motor is extremely professional.
I didn't look it over much, but with what you mentioned I could see it running very solid 7's with great mileage and driveability. I'll try to get notched86 and his buddies to get more info out of him tomorrow.
its possible and depending on how different the Downpipe would have to be I would really want to run stinger's header and ditch the tight outlet elbow for a "true 3"". Get this thing flowing enough I can spin a gutted Holset. Of course then I'll be ditching the volvo too.
