i plan to turbo my car in about a year. but for right now i want some power should i go with the itr cams or crower. if i go with the itr cams will i need to upgrade the retainers and valesprings? how much power will i get of the itr cams if tuned correctly. will i need a new ecu so i can rev to 8400 or higher? thanks by the way i have a 1999 gs-r with i/h/e skunk 2 cam gears

it wouldn't be worth your money to get any cams...

gsr cams work the best with turbo...so get something else...
