HKS has developed a series of capacity upgrade kits, customized to suit various engine features, for those drivers who desire “more power and more torque.” By enlarging the engine’s displacement, these kits boost torque at lower RPMs. The utilization of premium-quality materials guarantees the resilience needed for aggressive tuning. Elements such as nickel-plated pistons, recognized for their sturdy anti-knocking attributes, along with fully counterbalanced crankshafts, and optionally available high-strength connecting rods in some kits, collectively enhance turbocharger function and torque growth.
A prime example of this strategy is the 2.8L STEP 2 kit, which has been further improved with rigid, lightweight forged “BCD” pistons.
Piston Kit
The piston design benefits from the use of A2618 alloy, which is renowned for withstanding high temperatures, enabling a slimmer wall structure. The bridge structure has increased the structural rigidity. Weight has been cut down and the piston skirt height has been lessened through profile refinement. A brief piston pit is combined with a lightweight boss component. Furthermore, a dual coating of fluorocarbon resin and molybdenum contributes to friction reduction.

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.

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.

Shipping Policy
-+
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.
BP Pricing Difference

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 sales@bulletproofautomotive.com with any inquiries.
