Engine Overview: Mazda MX-5 Miata Engine (All Generations)

The Mazda MX-5 has had various engines under its hood over the years, upgrading from generation to generation:

### First Generation (NA, 1989-1997)

The original Miata that launched the modern roadster renaissance. Engine options:

The NA Miata engines were cast iron block with aluminum head, DOHC with 4 valves per cylinder, electronic multi-port fuel injection, and famous for high-revving smooth power delivery. Manual transmission only in many markets (5-speed Mazda M5 in early years, 5 or 6-speed in later years).

### Second Generation (NB, 1998-2005)

The “happy face” Miata with pop-up headlights eliminated and chassis improvements. Engine:

The NB BP-4W introduced Mazda’s S-VT variable valve timing system (on the intake cam) in 2001, providing improved torque and a higher redline. The rare Mazdaspeed Miata variant (2004-2005) added a small turbocharger for 178 HP.

### Third Generation (NC, 2006-2015)

The third-generation Miata grew larger and added a power retractable hardtop option. Engine:

The NC’s LF-VE engine (part of Mazda’s MZR L family) was the first MX-5 engine with VVT on BOTH intake and exhaust cams (Mazda’s S-VT dual VVT system). It also featured a forged crankshaft and other internal upgrades for higher RPM operation. Manual or automatic transmission. The PRHT (Power Retractable Hard Top) variant could lower its solid roof in 12 seconds.

### Fourth Generation (ND, 2016-Present)

The modern Miata that returned to lightweight philosophy after the NC grew larger. Engine:

The 2019 ND2 power upgrade was one of the most significant mid-cycle refreshes in MX-5 history. The PE-VPS gained 26 HP through:

• Revised camshafts with more aggressive profiles

• Lighter valvetrain components allowing higher RPM

• Larger throttle body

• Larger fuel injectors

• Redesigned exhaust manifold for better flow

• Revised intake system for higher airflow

• Redline increased from 6,800 RPM to 7,500 RPM

The 2019+ ND2 PE-VPS is considered one of the best Miata engines ever made.

Common MX-5 Engine Service Items (Honest Disclosure)

Honest disclosure of common service items:

• Timing Belt (NA / Early NB): 60,000-mile service interval. Engine is interference type , don’t neglect this service.

• Timing Chain (Later NB / NC / ND): No regular service interval; replace only if stretch develops at very high mileage (200,000+ miles).

• Valve Cover Gasket: Common service item at 100,000+ miles for oil leaks.

• Rear Main Seal: Some MX-5 engines develop rear main seal leaks at high mileage.

• Crank Angle Sensor: NA / NB CAS sensors can fail, causing intermittent starting issues.

• VVT Solenoid (NC LF-VE): Can develop issues at high mileage.

• Direct Injection Carbon Buildup (ND PE-VPS only): Direct injection means no fuel washes intake valves. Carbon buildup at 60,000-80,000 miles requires walnut blasting service.

• Oil Burning (Higher Mileage): Some high-mileage Miata engines develop piston ring wear and oil burning. Compression testing reveals condition.

The MX-5 Miata engines are generally extremely reliable when maintained per Mazda specifications. 200,000+ miles is common with proper care.
