The GT45 Turbo is a great option for any big displacement engine. Built using industry leading castings and the world's leader in high-quality center sections. The GT45 is a journal bearing unit that provides superior quality with outstanding durability. The reliability of a journal bearing combined with such a large turbine gives this unit the ability to flow massive amounts of air all while barely breaking a sweat. The T4 flange and V-Band outlet make this easily adapted to any turbo build. This turbo is used on our Grassroots Performance LSX Turbo 350z and has been the go-to turbo for larger displacement builds that are looking for a quality reliable unit without breaking the bank.
