In order to further improve the response using the 2.8 L HIGH RESPONSE KIT for RB26DETT, this engine is packaged with a crank angle sensor and an ignition coil.
* It is recommended to use HKS Racing Pro 10 W50 as the engine oil.

High-rigidity lightweight piston machined from A2618 material with high high-temperature strength
Dedicated crank with counterweight reduced to the limit
Dedicated lightweight pin expanded to Φ22 to cope with high combustion pressure
Lightweight crank damper that suppresses torsional vibration
Titanium valve spring retainer
NC processing of the combustion chamber. Shape that makes the best use of squish by making the volume of the combustion chamber as small as possible



As a result of pursuing improved response, a dedicated crank angle sensor and ignition coil are packaged.
