HKS Step 2 FA20 2.2L Complete Engine for Scion FR-S / ZC6 Subaru BRZ / ZN6 Toyota 86

The “HKS COMPLETE ENGINE POWERED BY HKS” epitomizes a comprehensive application of over four decades of cumulative technological knowledge drawn from HKS’s involvement in Gr. A, Drag race, D1 GP, and TSUKUBA Time Attack motorsport racing. The company’s ambition is to build superior racing engines that not only excel in various races but also showcase noticeable improvements in power and durability. The construction of these engines is undertaken in the same facilities, by the same engineers who have previously been engaged in race engine construction, with a constant focus on harnessing the knowledge and technology accrued from past racing experiences. A keen understanding of the real-life differences between an actual racing vehicle and a modified streetcar is crucial.

The “HKS COMPLETE ENGINE POWERED BY HKS” relies on their extensive knowledge adapted from numerous years of race engine construction. HKS employs newly cast cylinder blocks to notably heighten overall reliability, given that reclaimed blocks may contain minimal unseen damages. This strategic choice of new cylinder blocks emphasizes the HKS commitment to crafting precision engines. Rigorous deburring and chamfering further contribute to precision, while any associated components are also deburred to facilitate the assembly of the head or supplementary equipment, thus boosting work efficiency. A comprehensive three-tier cleaning system is used to remove remaining metal debris, enhancing accuracy and preventing potential engine issues.

Before the engine undergoes cleaning, blind caps are detached. The engine is then roughly washed, steam-cleaned, and given a final touch-up. The boring procedure is carefully managed, taking into consideration possible distortions from the dummy head and metal, using specifically appointed head bolt and gasket components. Each step contributes to the creation of exceptionally accurate engines, including the use of honing and cross-hatching techniques influenced by previous building experiences with race engines. Clearances are meticulously adjusted in each section, based on anticipated engine output. Pistons and conrods selected from the cylinder are fitted while ensuring balance. High-precision devices control the fastening torque and high-end performance angle. Operating under an optimal environment for engine assembly, HKS never compromises on quality.
