Product description
"DAP Upgraded 64.5mm Non-VGT Turbo Kit for 2007.5–2018 Ram 2500/3500 6.7L Cummins with .91AR Divided Turbine Housing.
This is a great performance replacement turbo for tuned 2007.5–2018 Ram trucks with the 6.7L Cummins. It features a lighter, high-flow 64.5mm billet compressor wheel and a 76mm inducer / 68mm exducer turbine wheel.
The turbo provides strong response and is well suited for towing and performance on tuned trucks. It performs especially well at high altitude, where the efficient 64.5mm compressor wheel helps maintain boost more effectively than larger wheels.
Power Rating & Housing Options:
Best for tuned trucks with peak HP of 575 HP or under, with up to 37% over stock injectors.
The .91 A/R turbine housing offers quicker spool-up, making it ideal for towing and daily driving.
The 1.00 A/R turbine housing provides a bit more top-end power and lower exhaust backpressure (spool will be slightly slower than the .91 A/R).
Consider the 1.00 A/R if you want more high-RPM performance compared to a larger 73.4mm compressor setup.
For even faster spool and improved high-altitude performance, a smaller turbine wheel or tighter A/R housing can be selected. Note that a smaller A/R housing may increase EGTs (exhaust gas temperatures) at high RPM and full load — always monitor EGTs.
Turbine housing features an HX40-style outlet, which is a direct fit for the 2007.5-2018 Ram.
Kit Includes:
Upgraded turbo with 64.5mm compressor wheel and 76/68mm turbine wheel
2-piece high-flow T4 exhaust manifold that flows approximately 33% more than stock
Manifold is drilled and tapped for EGT probe and boost/pressure fittings
Manifold finished with durable black high-temperature coating and retains EGR/emissions ports
Complete set of manifold, turbo, and EGR gaskets
Coolant plugs (2x), oil drain bolts, and new oil drain line
Important Notes:
This is a non-VGT fixed-geometry turbo. The factory variable geometry actuator is not used.
ECM tuning is required for safe operation and optimal performance (DAP does not provide tuning).
Professional installation and proper tuning are strongly recommended.
DAP buys good used cores. They will purchase your stock Holset HE351VE or HE300VG turbo and actuator for a competitive payout. Contact DAP for current core pricing and to receive a prepaid shipping label.
The compressor wheel on this turbo is compatible with BorgWarner S300 SXE-series turbos of the same size, allowing easy mixing of components for future upgrades."
