Here you go! JDM version of Silvia Spec S Autech. The engine got increased compression ratio from 10 to 11.7 : 1. It has same package just like Spec R car but this one has no Turbocharged. 0-60 mph is 5.7 sec and has top speed 145 mph when not limited. One think for sure, this car can set very fast laptime on Tsukuba. 1:11.83 exactly.
