HKS Complete Engine RB26 2.8L Step3 V-Cam
RB26 2.8L complete engine highest peak model
- Skilled workers assemble the highest peak 2.8L STEP3 kit
- Assuming use at high output, the heat drawing of the valve is improved by changing the material of the valve seat and valve guide.
- The EX side cam opening is widened to 280 ° to ensure stress-free elongation up to high rpm.
- Optimized combustion chamber shape by NC processing to suppress knocking
- Valve system that draws power up to high rpm with big valve, titanium retainer, reinforced valve spring, high lift cam, reinforced stem seal
- Adopts V CAM that supplements torque in the low speed range assuming the use of a big turbine
- Improved signal accuracy in the high rpm range with a dedicated crank angle sensor for 36 teeth and a cam angle sensor for V CAM
- Uses a proven reinforced oil pump to ensure stable oil pressure over the entire rotation range
* It is recommended to use HKS Racing Pro 10 W50 as the engine oil.
-
A high-rigidity, lightweight piston machined from A2618 material, which has high high-temperature strength.
-
Two-layer coating reduces friction coefficient at high surface pressure and high-speed sliding
-
Dedicated lightweight pin expanded to Φ22 to cope with high combustion pressure °
-
A big valve filled with sodium is used on the exhaust side to improve scavenging performance.
-
Full counter crank
ion nitriding treatment machined from nitrided steel increases surface hardness to the utmost limit -
The valve seat is changed to beryllium and the guide is changed to phosphor bronze to improve the heat drawing performance of the valve.
-
V CAM dedicated crank angle sensor 36-2 teeth
-
IN side: V CAM STEP Pro
EX side: 280 ° STEP2
Reinforced blow-by separator reduces oil carry-out -
Separator that stops oil outflow with multiple partitions
-
Dedicated emblem with DLC finish
-
Reinforced ignition coil that ignites stably even at high combustion pressure
