ISR Performance Turbo Kit - Mazda Miata NB 1.8 - With RSX2860 Turbo

Built around the 1.8 liter engine in the 1999 to 2005 Mazda Miata NB, the ISR Performance turbo kit with RSX2860 turbo is a complete bolt-on turbo system for owners who want more than the T28 version delivers. The extra displacement of the NB 1.8 pairs well with the larger RSX2860, which supplies the airflow to make real use of the engine's stronger bottom end and better flowing head.

Choosing This Kit
