This Turbocharger is a GTP38 with 66/88mm upgrade billet compressor wheel for performance use of 99.05-2003 Ford E&F Series Super Duty Pickups, this compressor wheel is not only intended for anti-surge purpose, but also support huge power gains, with the expanded wheel size and aggressive blade design, it can provide about 33% more airflow than factory 60/80mm cast compressor wheel to let your car more powerful. Because of the bigger compressor wheel, this turbo has a compressor housing with 4" ported anti-surge inlet(the stock one is 3"), so we put a new intake hose to fit that size. The size of turbine wheel is also expanded to 76/70mm, which let this turbo spin about 5% faster than the stock GTP38. The Thrust bearing is also upgraded from stock 270° to 360° thrust bearing, which is very necessary for high boost and performance applications, not only because of the full circle lubrication, but also the more and better designed oil feed holes.
