yeh disco potato the gt2835 is onli abit bigger than the turbo i have on there at the moment, its a redtop nics so the head flows alot better than other rb20s, ive looked around and the 3037s seems to b the way to go for the kinda power/response im looking at, theres a internaly stock rb20 no cams with a gt3037 in perth hitting 380 so i dont see a problem with me getting 400
