New for 2016, Tomei Poncams for all KA24DE equipped models. Because they are designed to be compatible with stock valve springs, and ECU tune Tomei Poncams are the best drop-in camshaft solution for the KA24DE powertrain.
This product is intended for turbocharged engines. When installing on a naturally aspirated engine, the optimal valve timing will need to be set using adjustable cam gears.
For further guidance on valve timing optimization, please refer to the installation manual and/or the 'Valve Timing Calculator' available on the TOMEI USA homepage.
Please note that all adjustments and/or tuning should be conducted based on the specifications of your particular vehicle/engine setup.
Includes a full set of two camshafts.
Features:
- Pre-Set Valve Timing
- Stable Idling
- Compatible with Stock Valve Springs
- Noticable Linear Power Gains
- Optimized Oil Feed Hole (Ensures steady oil flow to the journals)
VALC Valve Lift Profile Velocity, Acceleration, Lift, Control
The new VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' which in turn generates more power. (Greater area under the 'lift curve' = increased air intake.)
VALC Features:
- Optimized 'Velocity' and 'Acceleration'
- Designed for High Power Setups
- Optimizes Engine Performance
- Higher Lift Than Other Profiles of The Duration
- Reduced Stess/Wear on the Valvetrain
