The F20DET engine was basically a detuned race engine, a bit heavy but possibly Nissan's strongest ever engine. The stock engine can take massive boost and survive, while turning out incredible horsepower. Originally designed as the FJ24 for use in 240RS racing cars, it was in mass production as the FJ20 engine fitted to the DR30 Nissan Skyline. The FJ engine is very heavy at 366 lbs, heavier than the 318 lb Buick V8 3.5 liter engine. The FJ engine was produced in three variations: 1) FJ24E 2) FJ20E 3) FJ20ET.
