SPE 6.7L EMPEROR TURBO SYSTEM with S370 BallBearing Turbo 

The SPE 6.7L Emperor Turbo System is a 100% drop-in turbo system for the
2011-2019 6.7L Powerstroke.

This kit INCLUDES the s370 Ball Bearing SPE Turbo specifically built for the 6.7 platform.

This is the exact kit I am running on my 2017 F250 Platinum,  a quick note to add to this kit is that I would 100% recommend an MBRP downpipe in addition to this kit.  If you need one please email me upon ordering!  With the size of this turbo, I also recommend adding in the Warren Diesel 55% over Cp4 or an Exergy 10mm Cp4.  More air needs more fuel.  This kit with a 55% over or 10mm Cp4 on stock injectors will be an extremely fun reliable truck.

I performed this install with basic tools over the span of two days.  The included directions are spot on, the biggest thing I can say is that if you are tackling this install yourself (which is very possible) then take your time and remember it’s only nuts and bolts.

If you would like to go with a different size turbo then please let me know.



The SPE 6.7L Emperor Turbo Kit is a 100% drop-in turbo system for the 2011-2019 6.7L Powerstroke. This system is the perfect solution for the enthusiast wanting the reliability of a non- VGT turbo or the ability to support more power with their 6.7L Powerstroke. It can also be used as a replacement for the problematic Garrett GT32 single sequential turbocharger (SST) found on the 2011-2014 year model.

Due to the way SPE has designed the turbo system it is an effortless upgrade/replacement turbo option that even a novice can install. In fact, the hardest part is removing the factory turbo.

This turbo system does NOT require any extra components*. It can be used as a 100% drop in replacement or as an upgrade. It uses the factory driver’s side manifold and an included, SPE designed, aftermarket passenger side manifold. This kit maintains the factory driver side up pipe (passenger side up pipe and manifold are no longer used), 2015+ style downpipe, 15+ lower intake manifold, and 11-19 upper intake manifold.

The system is capable of supporting stock power levels all the way up to 800hp.

This kit includes the same SPE s370 ball bearing turbo I am running on my 2017 F250 Platinum.  When driving with the cartridge ball bearing turbocharger you will find an exceptionally crisp and strong throttle response. We are seeing 15% faster spool up than traditional journal bearings across the board on the three available sizes we offer. This also helps with lowering EGTs and intake temps.

To explain this the easiest way possible the driving characteristics of this s370 BB turbo resembles a stock Un-Tuned truck on the very bottom, and I mean right off the bottom in very low RPMs, BUT do not let that fool you because in just another second this thing spools and all hell breaks loose!!

When SPE went into developing this system they wanted to eliminate the problems that currently plague kits on the market; one being the turbo up pipes. All other non-VGT turbo kits on the market require one or two custom up pipes. This seems great when it’s sold to the customer as if though its an upgrade. Unfortunately, it is not, in our opinion. The problem with custom up pipes is the fact that they are a wear item. The bellows that allow for expanding and contracting are the actual wear item. Metal can only expand and contract so many times before cracking. When this happens to an aftermarket kit (not an if but when) you have to get another set of uppipes. Now this is where the main problem comes into play, availability. Even in the best circumstances, 1-2 days can really hinder the customer with a $50,000+ immobile paperweight.

SPE has removed this issue from the equation by eliminating the need for it. The SPE Emperor Turbo System still utilizes a bellow in the factory driver side up pipe which is still retained. Thus creating a system that only has one up pipe and it can be replaced with a factory part available via a Ford dealership or auto parts store.

The main hurdle in the design was doing all of the design work and still keeping it drop in capable all while still utilizing the factory intake manifolds. This helped in keeping the kit cost down for the customer just wanting to only replace the turbo and not all of their intake piping.

The SPE Emperor Turbo System also utilizes a standard T4 Flange on the exhaust manifold. The kit was designed to use the exhaust manifold allowing you to change turbo size without having to change to different up pipes even if moving to a different frame turbo size all together such as when going from an s300 to an s400. This is unlike most other comparable kits on the market.

This system was also designed with modularity in mind. SPE wants our customers to be able to start with the basic system if they choose, and be able to upgrade later with minimal cost and waste.



  • Exhaust Manifold– Cast out of 600 series ductile iron.  SPE’s design retains the original Hot-V principles of getting the heat and exhaust flow to the turbo as quickly as possible. SPE designed the manifold to operate with dual volute T4 turbos. This manifold also has exhaust pulse optimization-based off of runner lengths and engine firing order, one major key to great turbo spool up. A factory EGT bung is also cast in.
  • Turbocharger – The SPE turbos were designed in-house and are upgraded versions of the popular S300 series. Weak points were addressed including much higher quality castings, bearing material, and machine work, and the end result is an even stronger, better design. They are currently available in 3 versions a 63mm, 66mm, 70mm compressor inlet size. All models will have an 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. Almost all the parts are compatible with the standard s300 turbos. Including turbine housings and rebuild kits, to help with serviceability and longevity.
  • Pedestal –  The Pedestal is hard anodized to minimize oxidation and corrosion common on raw aluminum. When bolted to an iron block this helps to also minimize leaks over time. The oil return is a form fit silicone hose allowing for easy turbo installation and is much more reliable than a steel flex drain. The drain is also a no fuss push-in design with no fittings to tighten or worry about.
