Engine
| RB2.8L specification is introduced for the first time as an engine menu. Based on the know-how cultivated in the NISMO complete cars "R33 400R" and "R34 Z-tune", the R4 is a tuning engine that allows you to enjoy torqueful performance in the entire area. Based on the R3 engine, the displacement was increased to 2.8L by boring the block and replacing the piston, crank and connecting rod. The overwhelming torque in the middle and low rev range brought about by 2.8L realizes a comfortable run in every scene. * R4 specifications are different from 400R / Z-tune specifications |

| Engine Model | RB26DETT "R4 (R-tune concept ENGINE Spec 4)" Specification |
| Total Displacement | 2,771 cc |
| Maximum Output | 500 ps (estimate) |
| Maximum Torque | 55 kg · m (estimate) |
| R4 New Parts: | |
 |
GT crankshaft The crankshaft used in GT500 and Z-tune. |
 |
GT connecting rod Spec1 The connecting rod used in GT500 and Z-tune. |
 |
Nissan genuine N1 oversized piston (Φ87) and piston ring |
 |
R3 turbo kit Compared to the conventional R1 turbo kit, the A / R of the compressor has been changed with the aim of improving torque in the mid-low speed range to improve the rise of boost pressure. As a result, the torque in the middle and low rpm range has improved to the same level as the genuine turbo, achieving both ease of handling on the street and performance and durability on the circuit. |
 |
Dedicated camshaft By changing the cam profile to characteristics close to the Z-tune specifications and optimizing the working angle and valve timing, the torque in the medium speed range is greatly improved. |
 |
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. |
