Engine

The S1 pursued ease of handling and speed on the street by combining the disassembly of the engine by a skilled mechanic, inspection of each part, overhaul, correction of stepping, weight adjustment, balance adjustment, and special parts. The S2 was developed as a normal evolution model of the S1 with the aim of increasing the torque over the entire range from low speed to high speed. Flat torque characteristics improve handling on the street. In addition, pickup and acceleration has been improved so that the driver can enjoy driving on the circuit. S2 is an engine for occasional circuit driving while emphasizing the ease of handling on the street. Introduced approx. 2012

(S1 parts)
Engine Model RB26DETT
"S2 (S-tune concept ENGINE Spec 2)" Specification
Total Displacement 2,568 cc
Maximum Output 400 ps / 6,800 rpm
Maximum Torque 45 kg · m / 5, 600 rpm
S2 New Parts:  
S2 dedicated camshaft

By optimizing the cam profile, it eliminates the dullness in the low rotation range peculiar to turbocharged vehicles, and realizes a characteristic that can comfortably increase to the high rotation range.
Fuel injector 570cc (NISSAN GT-R (R35) genuine)

Fuel delivery pipe For R35 injector conversion (NISMO)
Metal head gasket
S2 dedicated ECM
S2 ornament
Designated oil

COMPETITION OIL type 2193E (5W40) is the designated oil.
Existing Parts from S1 Engine:  
BNR34 Genuine turbocharger

BNR32 and BCNR33 are changed to BNR34 genuine ball bearing type turbo. The adoption of a ceramic turbine wheel improves the rise of the boost pressure from the low rotation speed range, and improves the torque and response from the low and middle speed ranges.
Large diameter turbo outlet

Larger inner diameter and less change in cross-sectional area, and at the same time, the provision of a bulkhead reduces exhaust pressure and improves turbine efficiency. The exhaust pressure from the turbo and the exhaust from the swing valve merge smoothly, reducing mutual interference of exhaust and improving boost controllability.
