RB26DETT engines in the R32, R33, and R34 GT-R quickly outgrow the factory intercooler once boost and power levels increase. The GReddy/Trust SPEC-R Type 23F Intercooler (12020208) is a high-capacity upgrade engineered for serious performance, featuring a large core (L600 x H302 x W100mm) capable of supporting up to 700 horsepower. With cast GReddy end tanks and 80mm inlet/outlet sizing optimized for the stock intake plenum, this intercooler delivers superior heat exchange, reduced pressure drop, and consistent charge air temperatures even under the most demanding track or street conditions.
Designed specifically for the RB26DETT platform, the SPEC-R core maintains excellent thermodynamic balance while providing the cooling capacity needed for twin-turbo or large single-turbo setups. The result is stronger, more repeatable power delivery, improved turbo efficiency, and reduced risk of heat-related power loss or detonation. This is the intercooler of choice for builders who refuse to compromise on cooling performance when chasing serious horsepower.
At Terra Firma Automotive, we supply this genuine GReddy/Trust SPEC-R Type 23F Intercooler as a premium cooling solution for R32, R33, and R34 GT-R owners. 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.

Questions & Answers
Ask a Question-
Good day - Can you lease let me know if any bumper modification is required for fitment?
Hi Andrew,
This intercooler should be a direct fit with 80mm outlets (though could require some trimming of the bumper due to variability in bumper spacing). However, given that we don't know if there have been any modificaitons to your car, we cannot guarantee exact fit.
Thanks!
