I stumbled across these pics the other day of a time attack inspired Nissan S15 from Out Trash of Numazu City, Shizuoka Prefecture, Japan. The SR20 has been taken to 2.2L courtesy of Tomei pistons, rods & crank. Power is 460ps @ 1.5bar thanks to Tomei cams and an HKS GT2835R turbo. All controlled by an Apexi Power FC.
Here is a short video of the car at Tsukuba:- http://www.out-trash.com/img/mpeg/s15-02.wmv
