The car he was fined in was the 0-300 Supra with the RB26, this is the GT 300 Pro Supra
But don't you think during R&D they would know that? Do yo think they just went "hmmmm what have we got laying around"?
As for the extra injectors, a large number of fuel rails eg - Greddy support 2 sets and require extra injectors to pulg the holes, whats wrong with that?

Background: The car's inspiration came from JGTC. The cars performance, however, became an inspiration for many to follow. The body design is completely original by Mr. Nagata, himself as is all the tuning. The car was used in many high speed trials and competitions. The smaller and lighter 3SGTE engine is set back far enough for the car to be considered to be a MR layout vehicle and for the front radiator to be mounted totally flat in the engine bay.
