if you click on the link, you see that it has been swapped with a 6 cylinder toyota engine.
Also, the video seems like it's been shot using a photo camera. There's no Image stabilization in any of the videos, and the frame rate is extremely low, I think somewhere around 25....
Just a cheap 20-30k video camera with 50 or 60 fps would have made the drift part look awesome. Rest slow parts are nice.
