ISR Performance Complete 1989-1993 NA Mazda Miata 1.6 Turbo Kit

ISR Performance is excited to present its latest turbocharger kit for the Mazda Miata NA 1.6 engine. This 1.6L Miata turbo kit is one of the most comprehensive on the market, offering an excellent balance between quality and affordability. Despite the attractive price point, no compromises were made in the design or materials.

This kit is engineered for compact T25/T28 GT-style turbochargers and features a fully tubular schedule 10 turbo manifold to prevent cracking, along with 304 stainless steel exhaust components for durability. The chassis-specific intercooler comes with a custom mounting bracket for a secure installation, paired with fully polished aluminum intercooler piping. Additionally, the kit includes AN oil feed and water lines, as well as an AN turbo drain line with an aluminum weld bung designed for the factory oil pan.

Designed with aftermarket ECUs and MAP sensors in mind, this kit includes the proven ISR RST25/28 turbocharger, ensuring a complete bolt-on solution.

The kit also features a modular hotpipe compatible with ISR HKS, GREDDY, and TIAL flanges (sold separately).

Please note: A 2.5" hole will need to be drilled for intercooler pipe routing.

• RST25/28 Turbocharger
• Schedule 10 Bottom Mount Turbo Manifold
• Intercooler and Piping Kit
• Turbine O2 Housing & Downpipe
• Full Oil and Water Turbo Lines with 10AN Aluminum Weld Bung for Oil Pan
