Ive looked at all possible options for an all motor build. While it is possible, boostin' is cheaper. So What kit would you all recommend? The last issue of turbo magazine had a gsr with only cat-back exhaust and edelbrock turbo kit. I don't know the exact numbers but it was like 250ish/160ish hp/tq. But the kit is like 3 grand +! did anyone piece together a good one?
