Fitted to: Clubman Race Spec (CRS), Customer Cars



R1 has achieved overwhelming power and high durability by combining high-precision work with high-performance parts such as port step correction by skilled mechanics, piston connecting rod weight adjustment, crank & pulley integrated balancing. The R2 was developed as a normal evolution model of the R1 with the aim of improving medium speed torque and accelerator response while maintaining high performance and durability reliability. It has improved feeling in street use and excellent pickup characteristics at the start of a corner in circuit driving. It has high acceleration performance in every scene.

Introduced approx. 2012

(R1 parts)
Engine Model RB26DETT
"R2 (R-tune concept ENGINE Spec 2)" Specification
Total Displacement 2,568 cc
Maximum Output 450 ps
Maximum Torque 48 kg · m
R2 New Parts:  
R2 dedicated camshaft

The cam profile has been changed to a characteristic close to the Z-tune specification, and the torque in the medium speed range has been significantly improved by optimizing the operating angle and valve timing.
Genuine injector and dedicated delivery pipe for NISSAN GT-R (R35)

Uses genuine injector for NISSAN GT-R (R35) with excellent fuel atomization performance. The engine revs up lighter and the response improves. In addition, gasoline dilution is low, and it is effective in improving fuel efficiency when used in combination with low-viscosity oil.
