Yeah they are regular sr16's I placed N1 cams & pistons to save space on the vid didn't notice ppl would think they were N1 pistons but anyways their normal ones.
and the car was street driven to the track which is 1:30 hrs away from them. Incredibly it had a bit of 89oct on the tank and got mixed with 91 oct. since we don't get 93 anymore and the car ran like that.
