Features:
Up-Pipe Conversion
This kit directly adapts the 23+ exhaust manifolds to a 2015+ turbo using newly designed up-pipes with proper routing for correct fitment. The included up-pipe gaskets and turbo gasket ensure a clean, leak-free installation.
Engine Mount Hardware
Because 2011–2016 trucks use smaller engine mount bolt holes, this kit provides the correct hardware for installing your existing mounts onto the 20+ block. The only modification required is to drill the original mounts so the updated larger bolts can pass through.
Cam and Crank Sensor Adapter
The 23+ cam sensor features a different connector and mounting style, so a plug-and-play harness adapter is included to integrate it with the earlier wiring. Simply swap your original crank sensor onto the new engine to complete the conversion.
Cooling System Block-Off
On 23+ engines, the transmission cooler is routed through the primary cooling system, which is not compatible with the 11–16 trucks. To correct this, the kit includes SPE’s water pump block-off, ensuring the cooling system functions properly in the earlier chassis.
Oil System Conversion Housing
The oil system conversion housing removes the variable volume solenoid used on the 23+ pumps and converts the system to constant-volume operation, matching the proven design of the 11–19 engines. It accepts SPE’s long or short CAT-style filters, includes threaded ports for the earlier oil pressure and temperature sensors, and utilizes larger internal passages for improved flow. All required hardware and auxiliary ports are included for a complete installation.
Kit Includes:
•SPE 23+ engine to 15 Turbo Up-Pipe Set
•Up-pipe to manifold gaskets
•Turbo inlet gasket
•Engine mount bolt hardware for installing the 11–16 mounts to the 23+ block
•Cam sensor wiring adapter (harness adapter, male-to-female)
•SPE water pump block-off flanges for trans cooler coolant ports (11-16)
•SPE billet 23+ oil filter conversion housing
•Oil filter housing gasket
•Auxiliary ports and all installation hardware
•Why SPE Built This
New 23+ long blocks are easier to get because they are in current production which also makes them less expensive. Older engines as new old stock will get increasingly scarce. This kit lets you reuse your existing turbo and supporting components while benefiting from the durability and availability of the newer engine.
Built for Convenience
No wiring hacks. No fabrication. No guessing.
Just the parts you need to bolt your components on, drop the 23+ motor in, and drive.
