The heart of GTIII-800 concept is a set of two new HKS turbines in a symmetrical layout. Turbos employ a light compressor wheel to produce very linear boost and might be installed as a simple turbo upgrade. With engine modifications this kit makes it possible to reach 800 ps. However, for that kind of power an upgrade of engine internals is required. We recommend HKS pistons and conrods, like we used in our test.
