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.

Key Engineering Features

NA / NB Engines (B6ZE, BP-ZE, BP-4W):

• Cast iron block, aluminum head construction
• DOHC, 16 valves
• Multi-port electronic fuel injection
• Timing belt (NA / early NB) or timing chain (later NB with VVT)
• 5-speed or 6-speed manual transmission options

NC Engine (LF-VE MZR):

• Aluminum block, aluminum head (lighter than NA / NB)
• DOHC, 16 valves
• S-VT dual variable valve timing (first MX-5 with VVT on both cams)
• Forged crankshaft (sport variant)
• Multi-port electronic fuel injection
• Timing chain (no timing belt service)

ND Engine (PE-VPS SkyActiv-G):

• Aluminum block, aluminum head (lightest MX-5 engine)
• DOHC, 16 valves
• Dual VVT (S-VT) on intake and exhaust
• SkyActiv-G direct fuel injection
• High compression ratio (13.0:1 for SkyActiv-G)
• 4-2-1 exhaust manifold design
• Timing chain (no timing belt service)

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.
