Looking into crystal ball and seeing sometime in the future a turbo upgrade for my 1JZ powered supra. I'm really not sure what my target HP would be. I do know how I plan to use my supra. I don’t anticipate using it in Drag racing. It is destined to be my autocross and even possibly road race, i.e. solo 1, club racing and track day car. So throttle response is Preferred. So, what would be the most rewarding route. stay with stock t12's ? or go with some sort of midsize single? Any Ideas ?
