HKS Step 2 V-CAM V2 RB26DETT 2.8L Complete Engine for R34 Nissan Skyline GT-R
The advanced “HKS COMPLETE ENGINE POWERED BY HKS” epitomizes the culmination of innovative tech-solutions blending. The company’s built technical mastery spanning four decades and their storied past in motorsports is encapsulated in this product. HKS has showcased their expertise across various racing platforms such as Gr. A, Drag Race, D1 GP, and TSUKUBA Time Attack, indicating a strong focus on creating robust and high-performance racing engines.
The “HKS COMPLETE ENGINE POWERED BY HKS”, birthed from exclusive traditions of race engine manufacture, continues to uphold its upper echelon status within the industry due to its all-encompassing competence. HKS values precision in the engine manufacturing by opting for brand-new cylinder blocks over refurbished ones, thus underlining their commitment to precision. Their exacting selection process reiterates the company’s striving for engine perfection. Their attention to detail extends to their rigorous deburring and chamfering procedures, ensuring parts compatibility and operational efficiency. A thorough three-step cleaning process removes any residual metal debris, bolstering accuracy and reducing potential engine problems.
The preparatory act for the comprehensive cleaning involves dismantling engine blind caps. The engine is then subjected to sequential cleaning stages involving initial cleanup, steam purging, and final polish. The boring process is executed with precision, accounting for possible variations from dummy heads and metals, supported by specific head bolt and gasket components. This meticulous approach at every step guarantees the production of superior engines. Honing and cross-hatching methods mirror traditional racing engine blueprints. Adjustments in each part’s clearance directly correspond to the expected engine output power. Extreme vigilance is exercised in aligning pistons and conrods with cylinders, utilizing high-precision tools for torque tightening and angle management. Throughout these intricate procedures, HKS’s dedication to preserving their high levels of quality remains steadfast.
Step 2 V-CAM V2
- The unveiling of Version 2 is marked with significant enhancements in its intake and exhaust balance, primarily credited to the integration of a larger valve for the exhaust. Progress continued with bolstered intake and exhaust capacity, achieved by refining the port profile. Modifications were done to the valve seat too, which was reshaped to an “R” in a precautionary measure against delamination within boundary layers.

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.

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
