⚙️ Engine Specifications

Primary Engine:

13B-MSP Renesis Rotary Engine

Performance:

Naturally Aspirated. Early models (2003-2005) typically produced around 238 hp (manual transmission) and 212 hp (automatic transmission) at high RPMs. Engine operates at high revs, with peak power often found above 7,000 RPM.

Fuel System:

Sequential Electronic Fuel Injection (S-EFI). Requires premium unleaded gasoline (91 octane or higher). Specific oil requirements for apex seal lubrication are critical for engine longevity.

Rotary Specifics:

Side exhaust port design. Unique lubrication system for apex seals. Requires specific oil changes and monitoring of oil consumption. Potential for apex seal wear if not maintained properly. Known for high oil consumption compared to piston engines.

🔧 Transmission

Transmission Standard:

6-speed manual transmission (Type: Mazdaspeed M6/FS6A-EL based)

Transmission Optional:

4-speed automatic transmission with Sportshift (Type: FN4A-EL)

Transmission Features:

The manual transmission is known for its precise feel and short throws. The automatic, while less performance-oriented, offered a convenient option. Clutch and transmission fluid specifications are crucial for maintenance.

📐 Dimensions

Exterior Dimensions:

Wheelbase: 106.4 inches. Length: 175.6 inches. Width: 70.9 inches. Height: 53.3 inches.

Curb Weight:

Approximately 3,000-3,150 lbs, depending on transmission and trim.

🛡️ Safety Features

Safety Ratings:

NHTSA: Generally good ratings for frontal and side impacts. IIHS: Good ratings in frontal offset and moderate overlap front tests for its era.

Active Features:

Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), Traction Control System (TCS), Dynamic Stability Control (DSC).

Passive Features:

Driver and front passenger airbags, side-impact airbags, front and rear side curtain airbags (optional/depending on trim), pretensioner seatbelts.

💡 Technology Features

Infotainment Features:

Available Bose premium audio system, CD player, available navigation system (early iteration), basic climate controls. Integration was typical for the early 2000s, not as advanced as modern systems.

Driver Assistance Features:

Traction Control (TCS), Dynamic Stability Control (DSC). ABS and EBD are standard.

Connectivity Features:

Limited. Typically Bluetooth phone connectivity was not standard or widely available on early models. Auxiliary input for audio devices might be present on some trims.

Engine Control Unit:

ECU controls fuel injection, ignition timing, and other engine parameters. This manual will detail sensor inputs and actuator outputs for diagnosis.

🔧 Maintenance

Service Intervals General:

Oil changes: Every 3,000-5,000 miles or 6 months, prioritizing specific rotary engine oil. Air filter: Every 15,000-30,000 miles. Spark plugs (rotary specific): Often at higher intervals, but check manual. Coolant: Every 30,000-60,000 miles. Transmission fluid: Manual every 30,000-50,000 miles, Automatic every 30,000 miles. Differential fluid: Every 30,000-50,000 miles.

Engine Oil:

API SG or higher, ACEA A3/B3 or A3/B4, viscosity typically 5W-30 or 10W-30 (check manual for specific rotary formulation oil with appropriate JASO standard for two-stroke oil injection into intake if equipped). Crucially, regular checking and topping up of engine oil is vital for apex seal lubrication.

Coolant:

Mazda FL22 Long Life Coolant (Green) or equivalent. 50/50 mix with distilled water.

Transmission Fluid Manual:

API GL-4, SAE 75W-90 (e.g., Mazda Genuine Manual Transmission Oil)

Transmission Fluid Automatic:

Mazda Genuine ATF MV or equivalent

Differential Fluid:

API GL-5, SAE 80W-90 (or specifically Mazda Genuine Hypoid Gear Oil)

Known Issues:

Apex seal wear and rotor housing scoring (especially if oil levels are neglected or engine overheats), carbon buildup in exhaust ports, starter motor issues (due to poor cranking compression on hot starts), catalytic converter failure, ignition coil failure (leading to misfires), oil pressure sensor issues, fuel pump failure.

Specific Procedures:

De-carbonizing exhaust ports, checking oil level frequently, proper warm-up and cool-down procedures for the rotary engine, using correct spark plugs (one long, one short for leading/trailing ignition).

📚 Vehicle History

Brand Heritage:

Mazda has a long history of innovation, notably with its pioneering of the Wankel rotary engine, a technology it has championed for decades, leading to iconic models like the RX-7.

Model Evolution:
