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

Building upon the acclaimed success of the CSF x TopRank Billet R32 (CSF #7217/7217B) and R33 (CSF #7219/7219B) Radiators, CSF has responded to customer demand by introducing a comprehensive line of High-Performance All-Aluminum Radiators for the R32, R33, and R34 Nissan Skylines. This new offering caters to enthusiasts and professionals seeking a non-billet alternative without compromising on quality or performance. With over five decades of expertise in radiator manufacturing, CSF stands as a trusted leader in engine cooling solutions. The CSF High-Performance All-Aluminum Radiator for the R33 Skyline is engineered to maintain optimal engine temperatures under the most demanding conditions, whether on the street or the racetrack. This radiator is essential for high-horsepower builds and motorsport applications where enhanced cooling capacity is critical to engine reliability and performance. The radiator features a robust 2-Row core integrating CSF’s exclusive B-Tube Technology. Unlike conventional oval “O” shaped radiator tubes, CSF’s innovative “B” shaped tubes are precision-formed and seam-brazed to achieve superior strength and sealing integrity. This advanced design allows the use of thinner, lighter aluminum material while enhancing cooling efficiency beyond standard welded tubes. The inlet located centrally within the seam-brazed tube increases the heat transfer surface area by approximately 15%, effectively delivering the cooling performance equivalent to two smaller tubes occupying the same space. This configuration facilitates “dual liquid laminar flow,” optimizing coolant movement and heat dissipation. Complementing the B-Tube design, CSF employs ultra-efficient multi-louvered fins meticulously aligned to maximize airflow through the radiator core. Each fin’s dimensions and orientation are precisely engineered and validated through rigorous wind-tunnel testing to ensure peak heat rejection efficiency tailored to the R33 Skyline’s specifications. Installation is straightforward with the CSF R33 Skyline radiator’s true “Drop-in fit” design, requiring no modifications. The radiator utilizes CNC-machined and welded OE-style brackets for enhanced durability and precise mounting. Inlet and outlet connections are designed to match original equipment specifications, allowing seamless integration with OEM or aftermarket hoses. This ensures a hassle-free upgrade while maintaining factory standards for fit and function. Product Details Design & Engineering The inline 6-cylinder engines powering the R33 Skyline, ranging from the reliable 2.0L RB20 to the legendary RB26, are renowned for their robustness. The RB26, in particular, is celebrated for delivering substantial power with commendable reliability. However, increased power output invariably generates additional heat, necessitating superior cooling solutions. While the stock radiator performs adequately under standard conditions, upgrading to a CSF High-Performance Radiator provides enhanced protection and thermal management, especially vital for vehicles with significant power modifications. CSF vs OEM The CSF radiator’s 2-Row 42mm core significantly increases coolant capacity and enhances heat dissipation compared to the original equipment. CSF’s Exclusive B-Tube Technology improves heat transfer efficiency by approximately 15% over conventional oval welded tubes. Additionally, the super-efficient multi-louvered fins maximize airflow through the core, elevating cooling performance. The increased number of cooling tubes and fin rows expands the surface area available for heat exchange, thereby improving overall radiator efficiency.
