The A70 Supra is where Toyota's performance story really began to take shape — and the JZA70 with the 1JZ-GTE twin-turbo inline-six is the one that enthusiasts still seek out today. It's a capable, tuneable platform, and like any turbocharged engine pushing hard, cooling is critical to keeping it at its best.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the JZA70, engineered to handle the thermal demands of the 1JZ-GTE in both stock and modified form. 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.
