HKS Step 2 V2 RB26DETT 2.8L Complete Engine for R34 Nissan Skyline GT-R
The ‘HKS COMPLETE ENGINE POWERED BY HKS’ serves as a landmark of modern technology. The expertise cultivated over four decades of steadfast dedication is exemplified in this feat of engineering. HKS’s expertise, honed through diverse motorsport engagements like Gr. A, Drag race, D1 GP, and TSUKUBA Time Attack, enhances their proficiency. The firm strives to manufacture racing engines that boast exceptional power and durability. Assembly of these engines takes place in facilities with a legacy of producing racing engines, resulting in machines that epitomize a vast wealth of knowledge and technological advancements from previous racing endeavors. Their pledge to uphold the unique attributes of both pure racing vehicles and custom streetcars remains steadfast.
‘Meticulously designed and manufactured, the ‘HKS COMPLETE ENGINE POWERED BY HKS’ leverages comprehensive technical knowledge to retain its industry-leading status. When it comes to reliability, HKS opts for brand new cylinder blocks over restored ones to avoid any overlooked defects. This mindful selection process is indicative of HKS’s commitment to crafting engines with exactitude. Their focus on fine details can be seen in the careful deburring and chamfering procedures that also perfect related parts, aiding integration with the head or other appliances, and thereby enhancing efficiency. A rigorous tri-phase cleaning process eliminates any residual metal pieces, enhancing accuracy and preventing potential engine problems.
Before initiating the cleaning procedure, engine blind caps are removed. The engine is then subjected to primary cleaning, steaming, and a final polish. The boring process is smartly executed, considering potential distortions from dummy heads and metal, thanks to specialized head bolt and gasket components. Mindfulness at each step ensures the creation of exceptionally precise engines. Techniques used during honing and cross-hatching draw upon lessons learned from historic race engine designs. Component clearance adjustments are made with the engine’s expected output in mind. Furthermore, meticulous care is given to the selection and alignment of pistons and conrods from the cylinder, using high-precision tools for torque fastening and angle control. Through these meticulous processes, HKS’s unwavering commitment to absolute quality is clearly visible.
Version 2
- The advent of Version 2 showcased improved intake-exhaust balance, brought about by the use of a larger exhaust valve. Efficiencies in intake and exhaust were further enhanced by refining the port profile and reshaping the valve seat into an R design. This strategic tweak played a pivotal role in countering the delamination of the boundary layer.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only.
Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well.
For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at
