well have been searching the past few days for a single turbo kit etc.. i am looking to make 520+ whp at 18 psi ( i would like as close to 600whp as possible ). so far the best streetable turbo i have found is a T67 with a .68 a/r. 4" dp+mp, hks ti 4" cat-back, fmic. now i am confused on a fuel set-up. i have been looking at the vpc and an safc, but the price between the two could almost buy an aem ems. so i am leaning towards a map ecu, i was wondering how that set up is? also i was thinking maybe a small shot of nitrous to get it up to 600whp. if someone could list the best route for my expetations that would be great. thanks in advance.
