ISR Performance Turbo Kit - Mazda Miata NA 1.6 - No Turbocharger Included

Our Miata NA 1.6 turbo kit, sold without the turbocharger so you can pick the T25 or T28 that fits your build and budget. One of the most complete bolt-on Miata turbo kits on the market without taking shortcuts on construction. Designed around compact GT-style turbochargers and built to handle real power.

What It Does

Provides everything you need to bolt forced induction onto a Miata NA 1.6 except the turbo itself, the BOV, the ECU, and the tune. The schedule 10 tubular bottom-mount manifold is built to resist the cracking that plagues thinner-wall cast manifolds. The 304 stainless exhaust components, chassis-specific intercooler and bracket, polished aluminum piping, and AN oil and water lines are all included. The hotpipe is modular and works with our HKS, GReddy, or Tial-pattern BOV flanges (sold separately), so you can run the BOV you already have.

Fitment

Fits the Mazda Miata NA 1.6 (1989-1993). Designed for compact T25 or T28 GT-style turbochargers (not included). Pairs cleanly with our IS-CSEXH-NA16 cat-back for a full exhaust system once the downpipe is in place.

Build Requirements (Sold Separately)

• T25 or T28 GT-style turbocharger
• Blow-off valve (works with HKS, GReddy, or Tial-pattern via ISR modular flange kits: IS-FLA-002 for HKS/GReddy, IS-FLA-006 for Tial)
• Aftermarket standalone ECU with MAP sensor support
• Fuel system upgrades sized for target power

Installation Notes

A 2.5" hole will need to be drilled for intercooler pipe routing. AN oil drain line with -10AN aluminum weld bung is included for welding to the factory oil pan.
