Koyo Performance Radiator – Toyota Supra JZA70 1JZ-GTE MT 1990–1993

Application: Toyota Supra | E-JZA70 (2D Coupe) | 1JZ-GTE 2.5L Twin Turbo Petrol RWD | Manual Transmission

Part Number: R0171 / KL010706R


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.
