It’s been two years since we shared Jason Ruby’s 1990 Nissan Silvia S13. In that time he’s continued to push the limits of the project. The engine bay now holds a turbocharged 3.2 L RB-series inline-six built by Matt Sims Performance making 1,140 horsepower to the rear hubs on 40 psi of boost and E85 fuel. The engine features a RB25DET head, RB30 block, Nitto 3.2 L stroker kit, Precision 7675 turboccharger, and Haltech Elite 2500 ECU. Power is sent to all four wheels through a Powerglide two-speed automatic transmission with a TCE converter, Nissan GTR transfer case and differentials with 4.11 gears. Jason’s current best is a 8.20 sec quarter-mile at 166 mph.
