HKS Step Pro VR38DETT 4.3L Complete Engine for R35 Nissan GT-R

The “HKS COMPLETE ENGINE POWERED BY HKS” is a potent testament to the widespread adoption of high-tech advancements, showcasing the finely tuned skills acquired over forty years. Its mastery is rooted in HKS’s participation in a variety of motorsport competitions, including Gr. A, Drag race, D1 GP, and TSUKUBA Time Attack. The firm’s goal is to engineer top-performance racing engines that offer increased power and remarkable durability. These engines, manufactured in the same facilities where earlier racing engines were developed, embody a wealth of knowledge and technological innovations borne from past racing exploits. The company is committed to preserving the distinct characteristics of both a pure racing car and a modified streetcar.

With a long history of superior racing engine design, the “HKS COMPLETE ENGINE POWERED BY HKS” relies on extensive expertise to maintain its leading edge. To ensure reliability, HKS opts for brand new cylinder blocks, recognizing the potential for undiscovered minor flaws in salvaged blocks. This careful choice symbolizes HKS’s dedication to crafting engines with precision. They meticulously follow deburring and chamfering procedures, which in turn deburr associated components, streamlining the integration of the head or additional equipment and thus boosting work efficiency. A detailed three-stage cleaning method removes all residual metal debris, enhancing accuracy and warding off possible engine issues.

Before initiating the cleaning process, engine blind caps are taken out. The engine sequentially receives an initial cleaning, steam-cleaning, and polishing for a final makeover. The boring process is conducted with extreme precision, considering possible distortions from the dummy head and metal. This precaution is achieved using specific head bolt and gasket parts. This painstaking attention throughout each phase ensures the production of supremely accurate engines. Honing and cross-hatching techniques draw on insights from past race engine designs. Alterations are made to the clearances in every part based on the expected engine output. Extreme care is applied in choosing pistons and conrods from the cylinder with perfect alignment, utilizing high-precision tools for torque fastening and high-performance angle management. In such an ideal setting, HKS’s strong resolve to uphold quality standards never wavers.
