Turbo kits turbo manifold
Hey guys. I'm going to do work on a friends hhr ss and he wants to run 12s in 1/4 mile. Has anybody gotten in the 12s here? If so how much horsepower do you have and what turbo upgrades did you get? I'm wondering if there was clearance issues between engine and firewall when going to a bigger turbo. Where do you guys get a turbo exhaust manifold from? Thanks
