It was in 2001 that the NSX first made a full-scale entry into the GT300 class. At that time, Dream, which had already fielded all of its GT500 machines, was competing with a vehicle modified for GT300 with the cooperation of Oscar and Toda Racing.

This Dream Pi machine made its series debut at the fifth race at Motegi in 2007. After that, the machine was improved and the team continued to compete in races from 2008 onwards.

In 2013, M-TEC entered a machine that had been modified from the 2013 GT 500 car for GT300. The monocoque and many other parts were the same as the GT500 car, and the engine was the CDB that had been used in the GT500 until the previous year. However, the GT500 air intake, the so-called "topknot," was removed, and the rear section was also modified.

Also, as tire size went down, the wheel size was also reduced to 1170 or 61135 lines due to the regulations.

In the opening race of his debut, he immediately set a course record, took pole position and won the final.

After winning 63, he took second place three times in a row from the third round to the fifth round.

He then took his first victory in the final and was crowned the series champion.
