HKS 2.8 Step Zero Capacity Upgrade Kit RB26DETT Nissan Skyline

For RB users that require more low and mid rpm torque, the RB26DETT 2.8L kit is ideal. Step Zero, Step 1, and Step 2 are available to suit the specifications of each user.

Piston: Used the forged material from high specification.

Connecting Rod: Used the forged material from high specification with H-beam design for maximum strength and durability. WPC shot-peening also contributes to strength as well as preventing metal fatigue.
* Stock rods can also be used.

Crankshaft: Used the forged material from high specification and fully counterweighted for best engine response. Intended rpm can be optimized for selected turbine.

Ideal kit when overhauling from standard internal parts

In addition to the increased displacement effect of 2.8L, STEP ZERO is the best solution for engines that require better response. The target of maximum revolution is best for stock or GT-SS turbine with greatly improved response.
The affordable price allows usage just for engine overhauling.

Features

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.
