Koyo Performance Radiator – Nissan Skyline GT-R R34 RB26DETT MT 2000–2002
Application: Nissan Skyline GT-R | BNR34 (2D Coupe) | RB26DETT 2.6L Twin Turbo Petrol AWD | Manual Transmission
Part Number: HH023194 / KH023194
The late-production R34 GT-R — covering the V-Spec II and Nür editions — represents the absolute pinnacle of the BNR34 lineage. The RB26DETT is a legendary engine that responds exceptionally well to modification, and at elevated power levels the cooling system becomes a critical component. Whether you're running stock boost or pushing serious power, keeping coolant temperatures in check is non-negotiable.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the BNR34, 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.
