CSF R34 Skyline GT-R/GTS High-Performance All-Aluminum Radiator - Black

Building on the remarkable success of the CSF x TopRank Billet R32 (CSF #7217/7217B) and R33 (CSF #7219/7219B) Radiators, CSF has responded to significant customer demand for a non-billet alternative by introducing a comprehensive line of High-Performance All-Aluminum Radiators tailored for the R32, R33, and R34 Nissan Skyline models.

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering cooling solutions that ensure optimal engine performance and reliability. The CSF High-Performance All-Aluminum Radiator for the R34 Skyline is engineered to excel in both street and track environments, making it an essential upgrade for vehicles with high horsepower configurations and motorsport applications requiring enhanced cooling capacity.

This radiator incorporates a robust 2-Row core design featuring CSF's proprietary B-Tube Technology. Unlike conventional oval "O" shaped radiator tubes, CSF's innovative "B" shaped tubes are precision-formed and seam-brazed to create a stronger, lighter, and more thermally efficient structure. This design enables the use of thinner aluminum material, which improves cooling efficiency while maintaining structural integrity superior to traditional welded tubes.

The unique "B-tube" configuration increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively delivering the cooling performance of two smaller tubes within the same spatial constraints. This design also facilitates dual liquid laminar flow, enhancing coolant circulation and heat dissipation. Complementing the tubes, CSF employs ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the radiator core. Each fin’s dimensions and arrangement are optimized and validated through rigorous wind-tunnel testing to ensure peak heat rejection efficiency.

Installation of the CSF R34 Skyline radiator is straightforward due to its true "Drop-in fit" design, requiring no modifications. All OE-style mounting brackets are CNC machined and welded to guarantee maximum durability and precise fitment. The inlet and outlet connections are engineered to match OEM specifications, allowing seamless integration with existing OEM or aftermarket hoses.

Product Details

Design & Engineering

The inline six-cylinder engines powering the R34 Skyline lineup, including the robust 2.0L RB20 and the legendary RB26, are renowned for their reliability and performance. The RB26 engine, in particular, is celebrated for its ability to produce substantial power while maintaining dependable operation. However, increased power output invariably generates additional heat, necessitating superior cooling solutions.

While the factory radiator adequately manages thermal loads in stock configurations, performance enhancements demand greater cooling capacity to safeguard engine integrity and optimize performance. The CSF radiator addresses this need with its advanced design and construction, providing enhanced heat dissipation and fluid capacity.

CSF vs OEM

The CSF radiator core features a 2-Row, 42mm thickness design, significantly increasing coolant volume and enhancing heat dissipation capabilities compared to the OEM single-row, 15mm core. CSF's Exclusive B-Tube Technology further augments heat transfer efficiency by approximately 15% relative to conventional oval welded tubes. Additionally, the multi-louvered fin design optimizes airflow through the core, contributing to superior cooling performance.

Increasing the number of cooling rows and tubes directly translates to a larger surface area for heat exchange, improving the radiator's overall effectiveness in maintaining optimal engine temperatures under demanding conditions.
