What is the best size turbo to use on a 1000 im on the fence with ether a gt30/40 or a gt35 both with billet wheels and ball bearing. what would be the best way to go. The bike will have a standalone not sure about an innercooler yet though. I hope someone can give me some more info than I have tried to get from others. The main answer I get is just buy our kit it will work for what you want.
