Hey im new to this site and thought id join since i have a skyline series 1 gtst rb25. I was hoping to achieve roughly 220 to 250 kw and was wandering if thats possible with say around 6 k to play with. Already has a manuel turbo boost controller 3 inch all way through hks exhaust . Motors been looked after has around 110km on clock . All advice would be appreciated and one last thing can you get that power on stock cam and injectors ect or all has to change.
