CSF x TopRank High-Performance Radiator For R33 Nissan Skyline GTS / GT-R [7219]

CSF x TopRank High-Performance Radiator For R33 Nissan Skyline GTS / GT-R [7219]

The Nissan R33 Skyline stands as one of the iconic legends in JDM automotive history. From the GTS to the GT-R, these vehicles continue to captivate enthusiasts whenever they make an appearance. In the United States, the Nissan GT-R remains one of the most sought-after JDM imports, regardless of its generation. Companies like TopRank have been instrumental in helping enthusiasts fulfill their dreams of owning these exceptional vehicles. Recently, TopRank collaborated with CSF to introduce a groundbreaking product: the Full Billet High-Performance Aluminum Radiator for the Nissan R33 Skyline. Many R33 Skylines imported by TopRank arrive in the United States retaining most of their original components, often including a 25+ year-old plastic radiator. While TopRank offers numerous upgrade options and services for customers before purchase, finding a high-quality, reliable replacement radiator for the Skyline proved challenging. Despite testing reputable aftermarket alternatives, none met the standards TopRank required for endorsement. Given their long standing relationship with CSF, TopRank turned to them as the ideal partner for this project. By combining TopRank’s extensive expertise in the R33 market with CSF’s decades of experience in designing and manufacturing high-performance cooling systems, the result is an unparalleled radiator for the R33 Skyline. This collaboration has set a new benchmark in quality and performance, delivering a cooling solution that stands unmatched in the industry.

Design & Engineering

• The inline-six engines in the R33 Skyline are renowned for their durability. Whether equipped with the 2.0L RB20 or the legendary RB26, these power plants are celebrated for their reliability. The RB26, in particular, is known for its ability to produce significant power while maintaining dependable performance. However, increased power inevitably generates additional heat, which can push cooling systems to their limits. While the factory radiator provides adequate performance, enhanced cooling protection is always a smart upgrade. Understanding this need, CSF designed a premium radiator engineered for maximum cooling efficiency and built for long-term reliability. As the R33 Skyline evolves into a prized collector’s car, investing in top-quality components is essential for restoration and modification projects. CSF’s Full Billet High-Performance Aluminum Radiator features fully CNC-machined billet aluminum end tanks, hand TIG-welded to a high-grade aluminum core. The result is a radiator that not only delivers unmatched cooling performance but also exemplifies exceptional craftsmanship and durability.

OEM vs CSF

• The 2-Row 42mm core significantly enhances both the fluid capacity and the heat dissipation capability of the radiator. CSF’s exclusive B-Tube Technology boosts heat transfer by approximately 15% compared to standard oval welded tubes. Additionally, the multi-louvered fins are designed for maximum airflow through the core, ensuring optimal cooling performance. The increased number of cooling rows further improves the radiator’s overall efficiency by providing more surface area for heat dissipation. Each end tank is constructed from CNC-machined billet aluminum, offering exceptional strength and durability. The CNC machining process ensures unmatched precision and uniformity, resulting in end tanks that align perfectly with the 42mm core. The tanks are then hand TIG-welded to the core, creating an ultra-strong and highly reliable radiator. The result is a premium cooling solution specifically engineered for the R33 Skyline, delivering unparalleled performance and durability.

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.”
