1990–1997 Mazda MX-5 Miata Forced Induction FAQ's

Please read our FAQs page to find out more.

Turbo vs supercharger on an NA Miata—what’s the driving difference?

Centrifugal/roots blowers give linear, immediate torque; turbos offer bigger headroom and adjustability. Both need fueling, cooling, and conservative tuning on stock internals.

How do I keep spool/response sharp with a bigger turbo?

Use efficient intercooling, tight piping, and a quality ball‑bearing CHRA. A well‑mapped boost control strategy maintains midrange without surge.

Do I need a stronger clutch and diff for FI?

Higher torque requires an upgraded clutch and healthy Torsen or clutch‑type LSD. Monitor gearbox/diff temps and shorten service intervals for track use.
