“$31,000 obo 45,000 original miles turbo S2000
Excellent example of a professionally built boosted/turbocharged s2000. So fast, but still a safe well built machine. Soft top is in perfect condition. It has been under a hard top most of its life (not included). Tons of amazing mods built and installed by professionals. Here is a list of some of the mods. I know I’m forgetting some.
The car came with a fully built engine from Inline Pro with an Inline Pro Sleeved Block, Inline Pro Connecting Rods, CP Forged Pistons (CR 9.0:1) and also an Inline Pro Valvetrain with InlinePro Dual Valve Springs & Titanium Retainers. The car is currently at 511whp at 13psi.
