This turbo kit claims to give the prerunner or the 4x4 3.4L tacoma 224hp at the rear wheels. It claims a 84hp improvement over stock. It produces this power with only 4pds of boost. The kit comes with everything but at $4090.95 I wont be buying it for a Tacoma any time soon. Go to www.performanceproducts4trucks.com pick tacoma as vehicle go to name brands and hit the see all brands. Theres a good write up on it in the new Performance Products Mag.
