Industrial Injection Super PhatShaft 66 03-07 5.9

The Super PhatShaft 66 was designed for trucks that have multiple fueling upgrades. This was our first high performance PhatShaft and was the first turbocharger on the market to utilize the 71mm exhaust wheel. It features a 66mm extended top compressor wheel but what makes the Super Phat Shaft 66 special is the 71mm exducer exhaust wheel and modified exhaust housing. The wastegate has custom dual oversized passages and a wastegate spacer plate for maximum effiency. Like all Phat Shaft turbochargers it is equipped with dual grooved bearings and an adjustable boost elbow. The Super PhatShaft 66 can support up to 750hp. The 66 is a drop in replacement however, a HX40 downpipe is required for installation if you wish to install the large flange turbo in to a 03-04 (305 hp) truck. 

Notes:

Turbo comes with all install components; however, a Boost Fooler is needed if truck is a 2004.5 or newer.(available below)
 

Comes ready to mount to the stock exhaust elbow and is a drop in replacement for the 6 Speed transmissions.

The HX40 downpipe and clamp are required for installation of the large flange version on 03-04 trucks(305 hp).(available below)
