Engine Specifications
13B-REW Twin-Rotor Rotary Engine
| Specification | Value |
|---|---|
| Engine Code | 13B-REW |
| Type | Twin-Rotor Wankel Rotary Engine |
| Displacement | 1,308 cc (1.3L) - 654cc × 2 rotors |
| Compression Ratio | 9.0:1 |
| Power (Official) | 255 hp @ 6,500 rpm (Type RZ), 265 hp @ 6,500 rpm (Spirit R) |
| Power (Actual) | 280+ hp @ 6,500 rpm (dyno measured) |
| Torque | 217 lb-ft @ 5,000 rpm (294 Nm) - Type RZ |
| Redline | 8,000 rpm (fuel cut at 8,500 rpm) |
| Fuel System | Sequential multi-point fuel injection (twin injectors per rotor) |
| Aspiration | Sequential twin-turbochargers (Hitachi HT-12 primary, HT-10 secondary) |
Sequential Twin-Turbo System
The 13B-REW employs an innovative sequential twin-turbo setup:
- Primary turbo (HT-12): Spools from idle to ~4,500 rpm for instant response
- Secondary turbo (HT-10): Engages at 4,500 rpm for high-RPM power
- Transition control: Computer-controlled sequential valve eliminates turbo lag
This system provides linear power delivery from 2,000 rpm to redline, with peak torque arriving at 5,000 rpm and sustaining through 7,000+ rpm.
Rotary Engine Characteristics
Unlike piston engines, the 13B-REW rotary has:
- No valvetrain: Rotors spin in eccentric motion, intake/exhaust via ports
- High RPM capability: 9,000+ rpm redline potential with tuning
- Compact size: Entire engine weighs ~250 lbs, fits low in chassis
- Oil consumption by design: Burns 0.5-1 quart per 1,000 miles (normal)
Drivetrain Specifications
| Specification | Value |
|---|---|
| Drivetrain Type | RWD (Rear-Wheel Drive) |
| Transmission | 5-speed manual (Type RZ, Spirit R) |
| Clutch | Single-plate dry clutch (225mm) |
| Front Differential | N/A |
| Rear Differential | Torsen Limited-Slip Differential (LSD) - Type RZ, Spirit R |

| Four-Wheel Steer | None |
Transmission Details
The 5-speed manual gearbox (Type RZ, Spirit R) features:
- Close-ratio gearing optimized for rotary power band
- Short-throw shifter with precise engagement
- Synchromesh on all gears
- Final drive ratio: 4.1:1 (Type RZ), 4.3:1 (Spirit R)
Note: Type R and Type RB models offered a 4-speed automatic transmission option, though manual transmissions are vastly preferred by enthusiasts for the connected driving experience.
Chassis & Suspension
| Specification | Value |

Suspension Design
The FD3S features a sophisticated double-wishbone front suspension and 5-link rear suspension with:
- Bilstein monotube dampers (Type RZ, Spirit R)
- Progressive-rate coil springs
- Front and rear stabilizer bars
- Lightweight aluminum suspension arms (Spirit R)
This setup delivers exceptional handling balance, with neutral cornering characteristics and minimal body roll.
Dimensions & Weight
| Specification | Value |
|---|---|
| Length | 4,285 mm (168.7 in) |
| Width | 1,760 mm (69.3 in) |

| Curb Weight | 1,270 kg (2,800 lbs) - Type RZ |
| Weight Distribution | 50% front / 50% rear |
Weight Distribution Philosophy
The FD3S achieves perfect 50/50 weight distribution through:
- Compact rotary engine mounted behind front axle centerline
- Fuel tank positioned ahead of rear axle
- Battery relocated to trunk for balance
This balance, combined with low curb weight (~2,800 lbs), gives the RX-7 a power-to-weight ratio of 9.8 lbs/hp (Type RZ), enabling exceptional acceleration and cornering.

Common Issues & Solutions
Apex Seal Failure
Symptom: Loss of compression, poor idling, hard starting
Cause: Carbon buildup on apex seals, overheating, detonation
Solution: Engine rebuild with upgraded apex seals ($5,000-$8,000)
Prevention: Regular oil changes, premix 2-stroke oil, avoid prolonged idling
Sequential Turbo System Complexity
Symptom: Hesitation at 4,500 rpm, underboost codes
Cause: Actuator/solenoid failure, vacuum leaks
Solution: Replace actuators, inspect vacuum lines ($500-$1,500)
Prevention: Single turbo conversion eliminates complexity ($4,000-$6,000)
Oil Consumption
Symptom: Burning 1+ quart per 1,000 miles
Cause: Normal rotary operation (oil injected into combustion chamber)
Solution: Check oil weekly, top off as needed
Prevention: Use high-quality synthetic oil, consider premix for longevity
