YO dudes!
Im thinking of upgrading my k03 to a k04 using bits off an s3.
I was wondering what the rough cost, bhp and torque would be and any extra stuff I need?
I got a price of 500 notes for k04 with lines, manifold, downpipe, injectors and a few boost pipes.
I have a forge dv and cai. I think i need an exhaust, remap and maybe fmic too.
