GT Crankshaft 
Features
Compared to the genuine NISSAN standard crank shaft, this is a long-stroke crankshaft with a stroke length of 77.7mm, 4mm longer than standard. By using in combination with genuine NISSAN piston (1mm over-size) and the NISMO GT connecting rod, upgrading the engine displacement to 2,771cc*1 is achievable. Die forging and fillet-roll construction was employed to increase the strength. Dynamic balancing treatment with crank only is already practiced.

Air Flow Meter
| Measurable airflow volume | Output (reference figures) | |
|---|---|---|
| 22680-RR580 | 2400kg/h | MAX 775ps |
| RB26DETT Genuine part | 1400kg/h | MAX 450ps |
| Other manufacture's parts | 1640kg/h | MAX 550ps |
- Use of the engine control unit is a prerequisite to the use of the air flow meter. If a production engine control unit, or the engine control unit for a different air flow meter is used, airflow measurement may be incorrect, causing a lean air-fuel ratio, or an advance of ignition timing, resulting in damage to the engine.
- Use of this product may be very difficult for those not certain about the compatibility of the engine control unit.
Intake Collector
Features
To find the most suitable shape for tuning engines (400ps to 600ps), the diameter and the length of the intake pipe, and the cross section shape of the intake collector was redesigned. The distribution of air to each tube was improved to provide more equal airflow volume, improving torque in the mid-speed range. Improved air intake volume between the pipes of the front and rear sides reduces the difference in air intake temperature on both sides of the turbine, optimizing the air-fuel ratio and ignition timing and providing increased output and fuel consumption. Simple bolt-on installation means that no additional work is required (however, the throttle linkage and throttle sensor must be adjusted).
* Intake temperature difference at the entrance of turbo chargers is improved averaging18% in 2,400 to 7,600 rpm range.
* At 4,800 to 7,600 rpm, power output is increased by an average of 1.8%, while fuel economy is improved averaging 0.4%.
Specifications
- Collector volume: 4.1 liter (genuine = 3.4 liter)
- Intake pipe length: 73.8mm (genuine = 48.5mm)

- This product cannot be installed with the engine mounted.
- Installation of this product will change the characteristics of the engine, necessitating adjustment of the engine control unit. Failure to do so very likely will result in damage to the engine.
- The engine improvement figures shown above are based on internal company testing. The actual level of improvement will depend on the engine specifications, conditions of air-fuel mixture and ignition timing, weather and the precision of measurement.
- This product cannot be used with single, large-diameter throttle chambers.
Air Inlet Pipe
[ Pipe extending from the turbocharger housing to the joint section ]
Features
Compared to standard part, it smoothes the airflow from two turbo-chargers, reducing pressure loss and improving engine response. A welded aluminum pipe structure was used to smooth the interior of the pipe, reducing inflow air resistance and weight. To reduce weakness to pressure in the joint sections and increase heat-resistance and increase durability, highly rigid, swell-resistant, heat-resistant silicon rubber was adopted.
Specifications
- Pipe section•••aluminum pipe, buffed finish (painting not required)
- Joint section•••reinforced silicon (blue, with NISMO logo)
- After installation, the main pipe will with the air cleaner duct. Heat the duct with a hair dryer or other heat source and bend it 10 to 15mm in a concave shape until it clears the pipe.
- For the BNR34, replacement of the air cleaner duct with an R-tune air cleaner duct (part no. 16554-RSR46, ¥34,650) will allow for installation without additional modifications.
- Installation of this part will increase boost pressure slightly. Be sure to adjust boost after installation.
For BNR34
Turbocharger
- Installation of these products will require adjustment of boost pressure characteristics and readjustment of the engine control unit. Failure to make the necessary adjustments can result in excessive boost pressure, or engine damage due to knocking or increased exhaust temperature resulting from excessive boost pressure, a poor air-fuel ratio or ignition timing.
R1 Turbo Kit
Features
In addition to the gasket kit required for turbo exchange, this kit provides all the parts needed for turbo exchange in the Skyline GT-R (BNR32, BCNR33) including the necessary water and oil piping around the turbo. With the use of the GT turbine, the change to ball bearings means that the boost pressure intercept point will be 400rpm lower than for the R33 N1 turbo. This is most suitable for racing engine aiming to achieve 450ps/50kg•m in combination with camshaft & ECM tuning.

Reinforced Timing Belt
Features
Core wires of tempered glass fiber, with the tooth fabric made of aramid fiber for immediate improvement in resistance to stretch, heat, cutting, tooth loss and abrasion. The result is greater endurance to the high heat, sudden change in rpm and torque that occurs with a tuning engine, so that maximum potential of the engine can be realized. Identical shape as genuine NISSAN part.
{Comparison with genuine NISSAN timing belt}
Strength resistance 1.2 times greater; heat resistance 1.8 times; cut resistance 3 times; tooth loss and abrasion resistance 9 times.
Oil Separator
cut model
cut model
Features
Blow-by gas exiting the combustion chamber can mix with engine oil and return during the intake stroke. While under normal condition oil collects in the intercooler, blowback can cause parts related to intake, such as the airflow meter, to become dirtied by oil. The NISMO oil separator separates the oil from the blowback gases returning from the cylinder head during the intake stroke, decreasing the amount of oil deposited in the intercooler. Because it is designed to return the separated oil to the oil pan, the oil separator also decreases motor oil consumption. The blowback gases are returned to the engine and are not released to the atmosphere, making this a valuable device for automobile inspection procedures
Specifications
- 50 round pipe
- Attachment bracket, pipes included
