HKS Step Zero Kit RB26 2.8L 86.5

"STEP ZERO" is recommended for stock or GTIII-SS turbine as more power cannot be output at more than 8,000rpm, and STEP ZERO has the best response.

Capacity Upgrade Kit RB26DETT 2.8L Step 0

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

Features

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.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 change the pitch between both ends.Newly designed φ86.5 piston.
Piston bore can be selected depending on engine block condition for φ86.5 or φ87.0.All MADE IN JAPAN (HKS in-house production)
