CSF x TopRank High-Performance Radiator for R32 Nissan Skyline GT-S / GT-R [7217]
The Nissan R32 Skyline, a true JDM icon, remains a favorite among enthusiasts, especially in the U.S., where it is one of the most sought-after imports. Companies like TopRank have been instrumental in helping enthusiasts acquire these dream vehicles. Recognizing the need for a premium cooling solution, TopRank partnered with CSF to develop a truly exceptional product: the Full Billet High-Performance Aluminum Radiator for the Nissan R32 Skyline. Many Skylines imported by TopRank arrive with original components, including 25+ year-old plastic radiators, which are often inadequate for modern performance needs. While TopRank offers a variety of upgrades and services for their vehicles, they struggled to find an aftermarket radiator they could confidently recommend for the R32. After testing all reputable options without success, they turned to CSF, a trusted partner with a longstanding relationship. Leveraging TopRank’s deep knowledge of the R32 and CSF’s decades of expertise in high-performance cooling, the collaboration resulted in the ultimate radiator solution for the R32 Skyline. This product sets a new standard for quality and performance, unmatched in the market.
Design & Engineering
- The inline-6 engines in the R32 Skyline, from the 2.0L RB20 to the legendary RB26, are known for their durability and reliability. The RB26, particularly in the R32 GT-R, is renowned for delivering big power while maintaining dependability. However, increased power inevitably generates more heat, and while the factory radiator manages heat adequately, greater protection is always beneficial. Understanding this, CSF designed a premium radiator to provide exceptional cooling performance and durability that lasts a lifetime. Given the R32’s status as a valuable collector’s car, using top-quality components is essential for restoration or modification. CSF’s radiator features CNC-machined billet aluminum end tanks, TIG-welded by hand to a high-grade aluminum core, delivering outstanding performance and reliability with a finish that matches its superior functionality.
OEM vs CSF
- CSF’s 2-row 42mm core not only significantly increases the radiator’s fluid capacity but also enhances its heat dissipation capabilities. Featuring CSF’s exclusive B-Tube Technology, the core achieves approximately 15% greater heat transfer compared to standard oval welded tubes. Additionally, the highly efficient multi-louvered fins maximize airflow through the core, delivering optimal performance. The increased number of cooling rows improves overall efficiency, providing more surface area for heat to dissipate from the coolant. Each end tank is crafted from CNC-machined billet aluminum, offering exceptional strength and durability. CNC machining ensures precision and uniformity, resulting in end tanks that seamlessly align with the 42mm core. The tanks are hand TIG-welded to the core, creating the most robust radiator available for the R32 Skyline. Included with each radiator is a 1.4-bar high-pressure cap embossed with the CSF logo. These high-pressure caps raise the coolant’s boiling point, offering an added layer of protection against overheating. While the radiator is designed to maintain safe operating temperatures, this added feature ensures extra security during extreme conditions.

About CSF
Back in 1947, a father and his three sons embarked on a business venture by setting up a small retail shop dealing in automotive parts. The family business blossomed over the years, evolving into an automotive garage specializing in radiator repair, and later, a radiator manufacturing facility. By 1975, the family-owned brand CSF was established, marking a milestone as the first to introduce import applications into the American automotive aftermarket, in line with the influx of Honda, Datsun, and Toyota vehicles. By 2009, the fourth generation of the CSF family joined the business, which had by then become a leading name in the import and domestic radiator and condenser markets, selling over 650,000 units that year despite an economic recession, and totaling over 35 million units to date. CSF’s portfolio expanded to include a diverse range of cooling systems, including commercial trucks, industrial and agricultural applications, marine coolers, intercoolers, pressure caps, and a pioneering Racing & High Performance Division. Today, CSF’s Racing & High Performance Division is renowned for designing and manufacturing advanced, efficient, and reliable cooling systems for a wide array of applications, from high performance all-aluminum direct-fit radiators to custom systems for racecars, power sports, off-road, marine, and industrial use. With over 50 years of experience and more than 40 million cooling systems sold worldwide, CSF has rightfully earned the industry title of “THE COOLING EXPERTS.”
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
