HKS 2.8 Step Zero Capacity Upgrade Kit RB26DETT

POINT-1

It is optimized for target turbines and rpm. Although it is full counter, the ultra lightweight design achieves quicker response than ordinary STEP1 or STEP2.

POINT-2

Full counter design decreases load on metals. The pitch of both connecting rod ends are not changed as ordinary kits and the stroke is adjusted by piston height. This design is less side pressure, less friction and more durable than other manufacturers' 2.8L stroke kits that changes the pitch between both ends.

POINT-3

Newly designed φ86.5 piston.
Piston bore can be selected depending on engine block condition for φ86.5 or φ87.0.

POINT-4

All MADE IN JAPAN (HKS in-house production).

• "STEP ZERO" is recommended for stock or GT-SS turbine as more power cannot be output at more than 8,000rpm and STEP ZERO has the best response.
• Since the power output range of GT2530KAI is shifted to higher rpm than GT-SS, in order to have wider power output range, "STEP1", that has maximum rpm of 8500rpm, is recommended. If budget allows, "STEP2" is recommended for better response.
• Since power output range of GT-RS Twin, T04Z and T51R KAI are shifted to higher rpm than GT2530KAI, in order to have wider power output range, "STEP2" is recommended, which has maximum rpm of 9000rpm.

HKS put all their know-how knowledge into engine parts from the data they have acquired from the drag race, round race, time attack and drift race. The HKS team provide Engine tuning ranging from Camshafts, Pulleys, Pistons and Rods to Timing Belts, Pump Upgrades and even Head Gaskets. The concept behind HKS engine products was to produce something the customers would truly be happy with.
