SPE Motorsport S300 Emperor Quick Spool Turbocharger

The SPE Emperor turbos were designed in-house and are upgraded versions of the popular S300 series turbos. The weak points were addressed including much higher quality castings, bearing material, and machine work and the end result is an even stronger, better design. The quick spool is available in 2 versions a 63mm and 66mm compressor inlet size. 63mm compressor model has a 76/68 turbine. The 66mm compressor model has a 80/73 turbine. It also has received slight design changes from the normal s300 variant to be optimized for the 6.7L engine to help with back pressure and spool up. The secret to this turbo is the optimized .83AR turbine housing. It was cast and developed specifically for the 6.7 powerstroke. This turbo should be considered for higher elevation and towing oriented vehicles that demand quick response and not maximum horsepower.

Available options include:

• S363 journal bearing
• S363 ball bearing
• S366 journal bearing
• S366 ball bearing
