I found an interesting video of the Spirit Tuned MR-S going up against Tsuchiya's Hachiroku. It's amazing watching Tsuchiya and Orido fly through the touge in these 2 cars. Both vehicles are using street tires, and produce under 200 horsepower. The MR-S is a 1.8 liter vs the AE86's 1.6 liter. The Amuse S2000 in the background is being used as a camera car. This is a great battle, and a must watch!
By no means is this a 'new' video. An old, but classic video is what I'd say. Enjoy.
