About the Fuji Grand Champion Series

The Fuji Grand Champion (GC)Race Series, held from 1971 to 1989 at Fuji Speedway, was one of Japan’s top-tier motorsport series, rivalling even the All-Japan F2 Championship in popularity.
With regulations allowing only production-based engines and banning factory works units, it became a battleground of innovation, creativity, and raw driver skill.

From the late '70s, most competitors began using two-seater race cars by Mooncraft, leading to the introduction of single-seaters in 1979 – and with them, the MCS was born.

What is the MCS-I?

Unveiled by Mooncraft in 1979, the MCS-I was a radical leap forward – a single-seat, center-cockpit machine replacing the traditional two-seater style.
Its debut season saw the legendary Satoru Nakajima win the championship, showcasing the MCS-I’s unmatched performance.

With only 17 original cowls ever produced, this is an extremely rare machine. Two chassis types were used:

• An aluminum twin-tube frame by Ito Racing (Aichi Prefecture)
• Modified March F2 monocoques

The vehicle offered here features the authentic Ito Racing twin-tube chassis, staying true to the original MCS-I spirit.

💎 One-of-a-Kind "MCS × 13B" Package

This specific combination – MCS chassis + 13B rotary engine – is virtually nonexistent on today’s market.
The 13B engine alone holds considerable value, being a genuine Sports Kit unit once used by a top Japanese GC team in 1983.
