What Are the Engine Specifications of the RX-7 FD3S?

The RX-7 FD3S uses the 13B-REW twin-rotor Wankel rotary engine with 1,308cc displacement. It produces 255 hp @ 6,500 rpm (Type RZ) or 265 hp (Spirit R), with actual dyno-measured output exceeding 280 hp. The engine features sequential twin-turbochargers and reaches an 8,000 rpm redline with fuel cut at 8,500 rpm.

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)

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. Peak torque arrives at 5,000 rpm and sustains 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)

What Are the Dimensions and Weight?

The RX-7 FD3S measures 4,285mm (168.7 in) long, 1,760mm (69.3 in) wide, and 1,230mm (48.4 in) tall with a 2,425mm (95.5 in) wheelbase. Curb weight is 1,270 kg (2,800 lbs) for Type RZ models with perfect 50% front/50% rear weight distribution.

Specification	Value
Length	4,285 mm (168.7 in)
Width	1,760 mm (69.3 in)
Height	1,230 mm (48.4 in)
Wheelbase	2,425 mm (95.5 in)
Curb Weight	1,270 kg (2,800 lbs) - Type RZ

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). This enables exceptional acceleration and cornering.

What Are the Common Issues and Solutions?

The most common RX-7 FD3S issues are apex seal failure (compression loss, poor idling), sequential turbo system complexity (hesitation at 4,500 rpm), and oil consumption (1+ quart per 1,000 miles is normal). Apex seal rebuilds cost $8,000-$12,000, turbo actuator repairs run $800-$1,500, and regular oil monitoring prevents damage.

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 ($8,000-$12,000)
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 ($800-$1,500)
Prevention: Single turbo conversion eliminates complexity ($4,000-$8,000)

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
