The S14 and S15 Silvia are two of the most iconic and enduring platforms in the performance world — clean, purpose-built sports coupes with the SR20DET turbo four-cylinder and rear-wheel drive. Whether it's a street build, a drift car, or a time attack weapon, keeping coolant temperatures in check is fundamental to getting the most out of the SR20DET under sustained load.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for both the S14 and S15, engineered to the same factory fit and mounting points as the OE unit. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.
Why Koyorad?
- Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
- Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
- Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
- OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
- Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
