The VG30ET, the engine used in the Nissan 300zx Z31 Turbo, is a time-tested engine that was overbuilt from the factory and is capable of making upwards of 500 crank horsepower on entirely stock internals.
This very same engine was used in the Electramotive (later to become NPTI) GTP ZX-Turbo that dominated the IMSA GTP races in 1988 and 1989. This engine, with extensive race modification and arranged in qualifying trim (with no restrictor plates) it was able to produce upwards of 1000HP.
Putting the other reasons for Electramotive's sweeping victories aside, the fully homologated race engine VG30ET proved to be both robust and reliable at those power levels.
