RB26DETT-powered R34 GT-R owners chasing extreme horsepower quickly discover the limitations of the factory intercooler. The GReddy/Trust SPEC-R Type 29F Intercooler with Upgraded Tank (12020219) is a high-capacity upgrade engineered for maximum performance, featuring a massive core (L710 x H302 x W100mm) and enhanced cast GReddy end tanks that deliver outstanding heat exchange and minimal pressure drop. With 80mm inlet and 100mm outlet sizing optimized for GReddy intake manifold plenums, this intercooler supports well over 700 horsepower while maintaining excellent turbo efficiency and consistent charge air temperatures under the most demanding conditions.

Designed for both twin-turbo and large single-turbo setups, the SPEC-R core with upgraded tanks provides the cooling capacity needed for sustained high-boost operation without the heat soak that plagues smaller or poorly placed units. The result is stronger, more repeatable power delivery, sharper throttle response, and the ability to run higher boost levels safely. This is the intercooler of choice for builders who refuse to compromise on cooling performance when pushing the limits of the RB26DETT platform.

At Terra Firma Automotive, we supply this genuine GReddy/Trust SPEC-R Type 29F Intercooler with Upgraded Tank as a premium cooling solution for R34 GT-R owners seeking maximum performance. Pairing it with a GReddy intercooler piping set (sold separately) creates a complete high-flow system that transforms your charge air delivery. Whether you’re building a street weapon or a dedicated track car, this intercooler gives your RB26 the cooling support it needs to run hard and stay reliable, delivering the performance and consistency that only a top-tier Japanese upgrade can provide.
