The OEM radiator utilizes plastic end tanks crimped to a thin aluminum core. Over time, constant thermal cycling causes the plastic to become brittle, leading to micro-cracks and catastrophic coolant leaks. Furthermore, the single-row factory core lacks the thermal mass and surface area required to effectively dissipate heat during sustained boost, resulting in severe heat soak, elevated coolant temperatures, and a high risk of catastrophic apex seal failure due to engine overheating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis performance radiator resolves these thermal limitations by upgrading to a 100% TIG-welded, all-aluminum construction. By eliminating the plastic end tanks, the structural integrity of the cooling loop is permanently restored. The unit features a massive 2-row core measuring 24.5\" x 12.25\" x 2.0\", vastly increasing fluid capacity and heat transfer surface area compared to the factory unit. The dual-pass fin configuration maximizes airflow dynamics across the core, ensuring rapid thermal dissipation even when the 1.3L rotary is operating under high-load track conditions. With matching 1.5-inch inlet and outlet dimensions, it provides a direct-fit drop-in installation while delivering the sustained thermal stability required to protect the 13B-REW from heat-induced detonation.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1993-1995 Mazda RX-7\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e13B-REW \/ FD3S\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e255 hp \/ 217 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN3A1-15-200A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1993 Mazda RX-7 1.3L Manual Transmission\u003c\/li\u003e\n  \u003cli\u003e1994 Mazda RX-7 1.3L Manual Transmission\u003c\/li\u003e\n  \u003cli\u003e1995 Mazda RX-7 1.3L Manual Transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eMaximizing power output and rotary longevity on the FD platform requires absolute thermal control.
