Following the notable success of the CSF x TopRank Billet Radiators for the R32 (CSF #7217/7217B) and R33 (CSF #7219/7219B) Skyline models, CSF has responded to customer demand by introducing a comprehensive line of High-Performance All-Aluminum Radiators tailored for the R32, R33, and R34 Nissan Skylines. This new offering caters to enthusiasts and professionals seeking a non-billet alternative without compromising performance or quality.
With over five decades of expertise in radiator manufacturing, CSF stands as a leader in thermal management solutions. The CSF High-Performance All-Aluminum Radiator for the R34 Skyline embodies this legacy, delivering superior cooling efficiency essential for both street-driven vehicles and competitive motorsport applications. Whether your build focuses on high horsepower output or endurance racing, this radiator is engineered to maintain optimal engine temperatures under demanding conditions.
The radiator features a 2-Row core incorporating CSF’s proprietary B-Tube Technology. Unlike conventional oval-shaped “O” tubes, CSF’s tubes are engineered in a distinctive “B” shape, which are meticulously formed and seam-brazed to ensure structural integrity. This innovative design allows the use of thinner, lighter aluminum material while enhancing cooling performance. The B-Tube configuration increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively providing the cooling efficiency of two smaller tubes within the same spatial constraints. This design facilitates dual liquid laminar flow, optimizing coolant movement and heat dissipation.
Complementing the B-Tube core, the radiator employs ultra-efficient multi-louvered fins that are precisely aligned to maximize airflow through the core. Each fin’s dimensions and orientation are carefully calculated and validated through rigorous wind-tunnel testing to ensure maximum heat rejection efficiency for the specific application.
The CSF R34 Skyline radiator is engineered as a true “Drop-in fit” replacement, requiring no modifications for installation. All mounting brackets are CNC machined and welded to OEM specifications, ensuring durability and precise fitment. The inlet and outlet connections are designed to match the original equipment manufacturer (OEM) standards, allowing seamless integration with existing hoses, whether OEM or aftermarket. This attention to detail underscores CSF’s commitment to quality, reliability, and ease of installation.
Product Details
Design & Engineering
The inline six-cylinder engines powering the R34 Skyline, ranging from the 2.0L RB20 to the iconic RB26, are renowned for their robustness and reliability. The RB26, in particular, is celebrated for its ability to generate substantial power while maintaining dependable operation. However, increased power output invariably results in elevated thermal loads. While the factory radiator offers adequate cooling for stock configurations, enhanced cooling capacity is imperative when pursuing significant performance upgrades.
CSF vs OEM
The 2-Row 42mm core significantly increases both the coolant capacity and the radiator’s ability to dissipate heat effectively. CSF’s Exclusive B-Tube Technology enhances heat transfer by approximately 15% compared to conventional oval welded tubes. Additionally, the multi-louvered fins are engineered to maximize airflow through the core, further improving cooling performance. Increasing the number of cooling rows expands the surface area for heat dissipation, thereby elevating the radiator’s overall efficiency.
