just a quick note to 2s2mk1frst not sure what cam to go for as i aint decided myself yet lol. just one thing i would change on your spec is the backbox on your scorpion exhaust , just changed mine as they are very restrictive as they are actually 1 3/4 diameter inside when the pipe is 2.5 inch!!! just changed mine and it made a noticable difference turbo spools up about 250rpm lower and im running same spec as you except ive got a full front pro alloy cooler. the rest of the scorpion system is fine by the way!
