The Shiden is powered by a Toyota 1UZ-FE 4.2 L naturally-aspirated V8[6] tuned by Toda Racing;[7] this engine would later be bored and stroked to 4.4 L in 2007.

[1] The proposed road-going version of the Shiden would have featured a smaller spoiler but would have retained a similar silhouette.

At the same time, Mooncraft announced that a privateer team would take delivery of a racing version of the Shiden road car to compete in the 2006 Super GT Series in the GT300 class.

Cars Tokai Dream28, the racing arm of Honda Cars Tokai, a chain of Honda dealerships based in Tōkai, Aichi, took delivery of a Shiden for the 2006 Super GT Series,[6] replacing the Vemac RD320R they had raced in 2005.

A non-score at the November Fuji race gave the #7 RE Amemiya Mazda RX-7 of Tetsuya Yamano and Hiroyuki Iiri and the Shiden a tie in points; the Shiden would finish the season strongly with second in the standings, losing to Yamano and Iiri on countback.

[12] 2008 was a quieter year for the Shiden as the team scored no wins throughout the season; their best finish was a 2nd place in Motegi.

For 2011, the Shiden was given a striking purple and green livery resembling that of the Eva-01 mecha as seen in the anime Neon Genesis Evangelion.

Changes to the Super GT rule structure were enacted in 2012 to take effect the next season; this would lead to the phasing out of JAF-GT Category C and D vehicles from competition, categories spanning prototype sports cars based on modified sports cars with few or no road-going counterparts.

Yura intended to sell the car with two spare Toyota 1UZ-FE V8 engines and a full set of parts[13] although ultimately the car did not find a buyer and remains with Mooncraft; Yura may have also planned to revive the concept of a road-going Shiden.

[9] The car was then sent into storage,[14] it having no opportunities to race due to constant regulation changes,[13] although it was displayed publicly in 2017 at a Formula SAE Japan event in Shizuoka.
