CSF R33 Skyline GT-R/GTS Full Billet Aluminum High-Performance Radiator - Black

The Nissan R33 Skyline stands as an iconic figure within the JDM automotive community, revered for its engineering excellence and timeless design. From the GTS variants to the legendary GT-R models, this vehicle continues to captivate enthusiasts and collectors alike. In the United States, the Nissan GT-R remains one of the most sought-after JDM imports across all generations, with import specialists such as TopRank facilitating access to these coveted machines. In a strategic collaboration with CSF, TopRank has introduced a product that exemplifies superior engineering and performance: the CSF R33 Skyline GT-R/GTS Full Billet Aluminum High-Performance Radiator in Black.

The R33 Skyline’s inline six-cylinder engines, whether the standard 2.0L RB20 or the renowned RB26DET, are celebrated for their robustness and reliability. The RB26 engine, in particular, is well-known for its ability to deliver substantial power outputs while maintaining dependable operation. However, increased performance invariably results in elevated thermal loads. Although the factory radiator performs adequately under standard conditions, enhanced cooling capacity is essential for those seeking to optimize engine performance and longevity. CSF has engineered this radiator to deliver exceptional cooling efficiency and durability, ensuring it meets the demands of both stock and modified R33 Skyline powertrains.

Constructed with precision, the radiator features full CNC-machined billet aluminum end tanks that are meticulously TIG welded by hand to a high-grade aluminum core. This manufacturing approach guarantees structural integrity and longevity, surpassing the capabilities of conventional radiators. The core itself is a 2-row, 42mm thick design that significantly increases coolant volume and heat dissipation surface area. CSF’s proprietary B-Tube Technology enhances heat transfer efficiency by approximately 15% compared to standard oval welded tubes, contributing to superior thermal management.

The radiator’s multi-louvered fins, measuring 6.5mm in height, are engineered to maximize airflow and surface contact with the coolant, further improving heat rejection. The increased number of cooling tubes and rows translates to a larger surface area for heat exchange, which is critical in maintaining optimal engine temperatures during demanding driving conditions. Each billet aluminum end tank is machined with exacting precision, ensuring a perfect fit with the core and enhancing the overall durability of the assembly.

Assembly integrity is maintained through hand TIG welding, a process that provides robust joints between the core and end tanks, resulting in the strongest radiator available for the R33 Skyline platform. The unit includes a 1.4 bar (20 psi) high-pressure radiator cap embossed with the CSF logo, which serves to elevate the coolant’s boiling point, thereby reducing the risk of overheating under high thermal loads. While the radiator is designed to prevent excessive temperatures, this feature offers an additional layer of protection during extreme operating conditions.

The CSF #7219B radiator is finished in a sleek satin black, providing a refined aesthetic that complements the engine bay. For those preferring a raw aluminum appearance, an alternative version (CSF #7219) is also available. Both variants maintain the same high standards of performance and durability.
