The KPGC10 is one of my all time favorite cars. The car is the true first GT-R and is almost 40 years old. When looking at the engine bay of the car in the picture it looks like it just came from the factory. It features some very cool parts like the individual throttle bodies and the exhaust manifold.
The S20 engine belongs to the original KPGC10 and is a six cylinder engine with 160hp in standard form. With the help of the ITB's and the other bits I think this car will have around 200hp. These cars fetch serious money nowadays especially the GT-R version, you can always choose for a non GT-R and make it look like a GT-R but for the real purists that's not an option.
