CSF R33 Skyline GT-R/GTS High-Performance All-Aluminum Radiator – Silver

The CSF R33 Skyline GT-R/GTS High-Performance All-Aluminum Radiator in Silver represents a significant advancement in cooling technology tailored specifically for the Nissan R33 Skyline series. Building on the success of the CSF x TopRank Billet radiators for the R32 and R33 models, CSF has responded to customer demand by introducing a non-billet, high-performance all-aluminum radiator line that combines superior engineering with practical installation and durability. With over five decades of expertise in radiator manufacturing, CSF is a trusted name in automotive cooling solutions. The R33 Skyline radiator is engineered to maintain optimal engine temperatures, ensuring peak performance whether on the street or the track. This radiator is essential for vehicles with high horsepower builds or those used in motorsports environments that require enhanced cooling capabilities. The radiator features a 2-row core design incorporating CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” tubes, the B-Tubes are specially engineered in a “B” shape, which are seam-brazed to create a stronger, lighter, and more efficient cooling tube. This innovative design increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively doubling the cooling efficiency within the same spatial constraints. The dual liquid laminar flow enabled by the B-Tubes optimizes coolant movement, enhancing heat dissipation. Complementing the core design, CSF utilizes ultra-efficient multi-louvered fins precisely aligned to maximize airflow through the radiator. These fins are meticulously measured and tested in CSF’s wind-tunnel laboratory to ensure maximum heat rejection efficiency, contributing to the radiator’s superior cooling performance. Installation is straightforward with the CSF R33 Skyline radiator’s true “drop-in fit” design, requiring no modifications. The radiator includes CNC-machined, welded OE-style brackets for enhanced durability, and the inlet/outlet connections are designed to match OEM specifications, allowing reuse of factory or aftermarket hoses. This ensures a seamless upgrade without compromising reliability or fitment. Product Details Design & Engineering The inline 6-cylinder engines of the R33 Skyline, ranging from the 2.0L RB20 to the iconic RB26, are renowned for their robustness and power potential. While the factory radiator performs adequately under stock conditions, increased power output generates additional heat that demands superior cooling solutions. The CSF high-performance radiator addresses this need by providing enhanced heat dissipation and fluid capacity, safeguarding engine components under strenuous conditions. CSF vs OEM The 2-row 42mm core not only increases the radiator’s fluid capacity but also significantly enhances its heat dissipation capabilities. CSF’s exclusive B-Tube Technology improves heat transfer by approximately 15% compared to traditional oval welded tubes. The multi-louvered fin design further maximizes airflow, ensuring the most effective cooling possible. The increased number of cooling tubes and fin rows translates to a larger surface area for heat exchange, elevating overall radiator efficiency.
