Nissan Skyline R32 R33 R34 GTR Connector Water Pipe RB26DETT

The Nissan Skyline R32, R33, and R34 GTR Connector Water Pipe for the RB26DETT is a precision-engineered OEM component essential to the cooling efficiency and reliability of the twin-turbo RB26 powerplant. This factory aluminum crossover pipe connects key points of the turbo cooling circuit, channeling pressurized coolant through the turbos’ water jackets to manage extreme heat and prevent oil coking or bearing failure during high-performance operation. Installed between the engine block and turbo system, it ensures balanced coolant distribution and consistent temperature control under boost, preserving both performance and turbocharger longevity.

Over time, original water pipes often corrode internally, introducing rust and scale into the cooling system that can clog critical passages and reduce efficiency. Replacing a corroded or leaking unit with a genuine Nissan connector pipe restores proper coolant flow and eliminates a common source of contamination. Unlike aftermarket reproductions, this OEM-cast water pipe features the exact geometry, wall thickness, and corrosion-resistant fittings specified by Nissan, ensuring flawless compatibility and durability.

Sourced directly from limited dealer stock in Japan, these connector pipes are becoming increasingly rare. Terra Firma Automotive is proud to offer these authentic RB26 components for enthusiasts dedicated to preserving their GT-R’s mechanical integrity and factory accuracy. Whether performing a concours-level restoration or a performance rebuild, this genuine Nissan connector water pipe is a critical investment in reliability, cooling performance, and long-term engine health.
