(Upgraded Compressor Housing+Repair kit+Billet Compressor wheel 66/88). Bore: 6.35 mm. You’ll get items in one kit. This is a GTP38 turbo upgrade kit with 66/88mm cast compressor wheel for performance use of 99.05-2003 Ford E&F Series Super Duty Pickups, the compressor wheel is not only intended for anti-surge purpose, but also support huge power gains, it can provide much more airflow than factory 60/80mm cast compressor wheel to let your car more powerful. Because of the bigger compressor wheel, the compressor housing has a 4″ ported anti-surge inlet(the stock one is 3″), so a new 4″ to 4″ intake hose is needed. The Thrust bearing in this kit is 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. The stepped gap piston ring also eliminates the oil leaking problem. Professional installation is highly recommended. Why Choose Us turbo system?
