Product Description

The GReddy 12040704 is the Ver. 2 Full Kit T-19 V-Mount Intercooler and Radiator system for the 1993-1995 Mazda RX-7 FD3S "Zenki" (early-model) equipped with the factory 13B-REW sequential twin-turbo rotary engine. Originally developed for drag racing and now equally popular with circuit time-attack and drift builds, this kit places the intercooler and radiator in an angled V-configuration at the front of the engine bay for direct, unobstructed airflow to both heat exchangers. The Type 19F intercooler features a lightweight 3-row tube-and-inner-fin core measuring 266 x 400 x 100mm with high-flow cast aluminum end tanks, while the TWR aluminum racing radiator (R32 size, 355 x 631.8 x 48mm) provides the cooling capacity needed for sustained high-load track driving. Air diversion panels channel airflow from the bumper opening and prevent escape, and the Ver. 2 design optimizes radiator angle for maximum airflow velocity with a piping layout configured for vented hood compatibility. As a Full Kit, this package includes the iconic cast aluminum 13B-REW compression pipe, two turbo outlet elbows, complete intercooler piping, suction tubes, and twin forward-mounted Airinx S open-air intake filters. A radiator breather tank, V-mount bracketry, and power steering cooler relocation components are also included. Battery relocation is required. For late-model JDM "Kouki" FD3S (1996-2002), use GReddy 12040705. For single turbo builds, the Standard Kit 12040703 omits the hot-side piping and intakes. Backed by GReddy's 1-year limited warranty.
