CAPACITY UPGRADE KIT RB26DETT 2.8L STEP2 86.5 BCD Based on the proven 2.8L STEP2 kit, this has been upgraded by combining it with a lightweight, high-rigidity forged BCD piston. Features (1) Piston kit Thin wall thickness achieved by using A2618 material, which is resistant to high temperatures. Structural rigidity increased by adopting a bridge structure. Profile optimization shortens skirt height and reduces weight. Shortening the piston pin reduces the weight of the boss. Two-layer coating of fluororesin and molybdenum reduces friction. (2) Crankshaft Stroke: 77.7mm Uses specially forged material. In addition, full counter provides good rotation balance and allows for high rotation. Lightweight pin journal and center are hollowed out to improve response. (3) Connecting rod Uses specially forged material. H-section to withstand powerful explosive loads. WPC treatment is applied to the surface to improve fatigue strength.

CAPACITY UPGRADE KIT RB26DETT 2.8L STEP3 This is a high-strength kit that demonstrates durability even in high-power, high-spec vehicle specifications. Piston kit + connecting rod + crankshaft Features This is a high-strength kit developed for use with high power. (1) Piston kit Piston weight: 324g Thin wall thickness is achieved by using A2618 material, which is strong against high temperatures. By manufacturing it by cutting, excess wall thickness is eliminated. By adopting a bridge structure, structural rigidity is increased. The two-layer molybdenum coating improves initial break-in and reduces friction. By shortening the piston pin, the boss part is lighter. By adopting a φ22 piston pin, bending rigidity is improved. By making the piston pin thinner and shorter, the weight increase from the conventional φ21 pin is eliminated. (2) Crankshaft Stroke: 77.7mm A machined full counter crankshaft is adopted. In order to reduce the burden on the main bearings under high power output, the counterweight is efficiently increased and the balance rate is increased. To accommodate maximum output, the material has been changed to nitrided steel and ion nitriding has been applied to increase surface hardness, thicken the hardened layer, and improve durability. (3) Connecting rod A machined H-section connecting rod made of nickel-chrome steel is used. Compatible with φ22 piston pins. The surface has been WPC treated to improve fatigue strength.

CAPACITY UPGRADE KIT RB26DETT 2.8L HIGH RESPONSE Piston kit + connecting rod + crankshaft Features To achieve the ultimate high response, we have achieved both high strength and light weight in each part. (1) Piston kit Piston weight: 324g We have achieved thin wall thickness by using A2618 material, which has high heat resistance. By manufacturing it by cutting, we have eliminated excess material. By adopting a bridge structure, we have increased structural rigidity. By using a two-layer molybdenum coating, we have improved initial break-in and reduced friction. By shortening the piston pin, we have reduced the weight of the boss. By adopting a φ22 piston pin, we have improved bending rigidity. By making the piston pin thinner and shorter, we have eliminated the weight increase from the conventional φ21 pin. (2) Crankshaft Stroke: 77.7mm A machined full counter crankshaft is used. The counterweight is efficiently positioned to achieve both low inertia weight and high balance. By deliberately limiting maximum output to 700 horsepower, weight is reduced to the minimum, improving response. (3) Connecting rod A machined H-section connecting rod made of nickel-chrome steel is used. Compatible with φ22 piston pins. The surface is WPC treated to improve fatigue strength.

CAPACITY UPGRADE KIT RB26DETT 2.8L STEP0 87.0 Forged piston 86.5mm + ultra-lightweight full counter crankshaft STEP ZERO is now available for those who want better response while still maintaining the increased displacement effect of the previous 2.8L model. The expected rotation speed has been set to the optimum level when combined with a genuine turbine or GT-SS turbine, providing overwhelming response. It is also significantly more affordable, making it ideal for engine overhauls and additional tuning. Features <POINT-1> >By optimizing the expected rotation speed to match the turbine to be combined with the conventional STEP1 and STEP2, we have achieved an ultra-lightweight design that achieves overwhelming response despite being a full counter. <POINT-2> The full counter reduces the metal burden, and the piston pin height absorbs the long stroke without changing the center distance of the connecting rod. The side pressure is suppressed as before, and durability is improved and friction loss is reduced compared to other companies' 2.8L kits that change the center distance. <POINT-3> In response to market requests, the piston is newly designed with a φ86.5. Depending on the block conditions, it can be selected with the conventional φ87.0. <POINT-4> Reliable MADE IN JAPAN (manufactured in-house by HKS). Allowable speed: 8000 rpm Maximum power output: 404 kW (550 hp)
