The SPE turbos come standard with a 360 degree thrust bearing, an optimized turbine for the 6.7 Powerstroke helping with back pressure and spool time, and a .91AR dual volute exhaust housing, which is interchangeable with any other 80mm s300 turbine housing. Borg Warner and Borg Warner based aftermarket options are available in housing sizes including .88AR, 1.0AR, and many other custom sizes available on the market. The SPE compressor covers are designed to work with the factory style intercooler pipe quick connect coupler. They also have a speed sensor provision.
The 63mm version is excellent for a factory turbo replacement. It is best suited for towing and all around driving. It works well with minimal to no modifications done to the vehicle's fuel system, yet will still support much higher power levels than any factory style vgt turbo. This turbo leaves room to grow for modifications down the road. The S363 is great for the person who is still towing and working their truck but wants to do a high pressure pump upgrade now or later.
The 66mm version is best suited for intermittent towing and a great middle runner for street driving/performance. This turbo works well with stock fuel up to a stroker CP4 pump. It also gives the head room to grow from no to minimal modifications. This turbo gives up a little bit of bottom end spool with factory fuel, but usually gains it back once a larger pump is installed and tuned.
The 70mm version is best for a modified truck used for minimal towing. It is best suited for trucks that have a modified Cp4 or dual pumps. It also works well with mild injector upgrades. This turbo starts to come alive at 700+hp but can still work in the 600hp range quite well. If your ok with having a little lag for lots of power potential the S370 is a great option.
