SR20DET engines in the S14 and S15 Silvia/240SX quickly outgrow the limitations of the factory intercooler, which is often poorly positioned and prone to heat soak under increased boost. The GReddy/Trust Intercooler T-23F is a high-capacity upgrade engineered to deliver superior charge air cooling with its efficient Type23F core dimensions of L600 x H302 x W100mm. This results in denser intake air, allowing for safer and more consistent power at the same boost level — and even greater gains when turning up the boost — while reducing the risk of detonation and improving overall engine efficiency.
The T-23F intercooler is particularly well-suited for manual transmission S14 and S15 models, offering excellent compatibility with oil cooler kits and supporting aggressive turbo upgrades. Installation requires bumper reinforcement and cover modifications, along with battery relocation or the use of a smaller battery (34B19L), but these steps are rewarded with noticeably sharper throttle response, reduced heat soak, and stronger, more repeatable performance on both street and track. Its robust construction and optimized core design make it a reliable choice for enthusiasts building high-output SR20DET setups that demand consistent cooling under sustained load.
At Terra Firma Automotive, we supply this genuine GReddy/Trust Intercooler T-23F as a premium cooling solution for S14 and S15 owners serious about unlocking the full potential of their SR20DET. It transforms the weakest link in the factory charge air system into a strong, efficient component that supports higher power goals while maintaining real-world drivability. For builders focused on reliable boost performance and maximizing their Silvia’s capabilities, this T-23F intercooler is one of the most effective and worthwhile upgrades available.
