RE Amemiya FD3S Super G — The Time Attack Champion

RE Amemiya's heavily-modified Mazda RX-7 FD3S, used in their time attack competition program, is one of the most successful purpose-built JDM time attack cars in history. RE Amemiya, founded by Yoshio Suzuka, is the most famous rotary tuning shop in Japan, and their FD3S has held multiple Tsukuba Super Lap records during the late 1990s and 2000s. The car represents the absolute peak of rotary engine performance and time attack engineering.

RE Amemiya Background

RE Amemiya was founded in 1972 by Yoshio Suzuka as a rotary engine specialty shop. Over decades, the shop became internationally famous for:

• Rotary engine rebuilds: Specializing in 13B and 20B engines
• Time attack competition: Multiple Tsukuba Super Lap victories
• Custom body kits: The "Amemiya kit" became iconic
• Race car preparation: Specifically for FD3S and RX-7 chassis

The Super G is RE Amemiya's flagship time attack car — built specifically to set lap records at Tsukuba.

The Build

The RE Amemiya Super G FD3S included:

• Engine: 20B-REW three-rotor Wankel (transplanted from Eunos Cosmo or built from scratch)
• Output: 600+ hp depending on tune
• Aerodynamics: Extreme custom Amemiya body kit with massive splitters and rear wing
• Chassis: Full roll cage, weight reduction to ~1,000 kg
• Suspension: Race-spec coilovers
• Brakes: Carbon ceramic or competition-grade
• Tires: Slick tires for time attack

The combination of the 20B three-rotor engine and lightweight chassis gave the Super G a unique advantage in time attack competition — combining high power with minimal weight.

Tsukuba Records

RE Amemiya's Super G held multiple Tsukuba Super Lap records:

• Unlimited class records: Sub-55 second laps at various tunes
• Rotary class records: Best rotary-powered times ever recorded
• Multiple win streaks: Dominated Tsukuba Super Lap events for several seasons

The 20B three-rotor engine was the key differentiator. Most time attack cars used piston engines (4-cylinder, 6-cylinder, V8), but the rotary's lightweight, smooth power delivery suited Tsukuba's tight corners perfectly.

International Recognition

RE Amemiya's time attack work brought international attention to:

• Rotary engineering: Showing what the 20B could do at the limit
• Time attack culture: Inspiring international time attack series
• Mazda RX-7 platform: Demonstrating its competitive potential
• Yoshio Suzuka: Personally as Japan's premier rotary engineer

Legacy

The RE Amemiya Super G FD3S is the most successful purpose-built time attack car in rotary engine history. It demonstrated:

• The peak of what rotary engineering could achieve
• That Japanese tuning shops could compete at the highest level
• The viability of unique engineering approaches to motorsport
• The cultural importance of time attack as a discipline

For RX-7 enthusiasts and time attack fans, the Super G is essential reference material. It's the car that proved the rotary deserved to compete with anything else on the planet.
