"Without question, the pinnacle of mid-engined Japanese sports cars is the Honda NSX Type-R. This high-speed version, the NSX-R Prototype LM, starts life as a standard NSX Type-R, but uses the addition of a lighter body and wider tires, along with a massive power upgrade for good measure.
The original NSX Type-R made its debut in 1992, and underwent many major refinements prior to its second-generation release in 2002. The new model was lavished with numerous aluminum and carbon fiber parts, along with major renovations to the drivetrain. Despite these additions, it still felt like something was missing; the enhancements to the engine were limited to just a bit of fine-tuning.
The hearty 3.2-liter DOHC V6 with i-VTEC has seen its bore increased to yield an impressive 552 HP, at an incredibly lofty 10,000 rpm. The engine has been repositioned to a longitudinal layout, and the gearbox has been installed upfront to mirror the setup found on the JGTC-spec NSX. The driveshaft is connected to the rear tires through the oil pan underneath the engine. With the new level of horsepower, and a high degree of handling capability, this car is ready to take on the world's greatest racing circuits.
Rather than stripping its interior, this NSX features luxurious leather-clad seats and wood trim, in a nod to its street-legal status.
Although this NSX Type-R LM remains only a dream, in the world of Gran Turismo, the possibilities are endless." This is from GT5 description.
