The 3.0 L (2,960 cc) VG30ET was available in early production with a single Garrett T3 turbocharger (6.7 psi (0.46 bar)) and a 7.8:1 compression ratio. The USDM version produced 200 hp (150 kW) and 227 lb·ft (308 N·m). In April 1987, the "W"-Series VG30 was released, horsepower was bumped to 205 hp (153 kW). ALL '87 models featured a T3 turbocharger (6.7 psi (0.46 bar)). In 1988 compression ratio changed to 8.3:1 and the turbo changed to a single Garrett T25 turbocharger (4.5 psi (0.31 bar)) to reduce turbo lag. No VG30ET was ever factory equipped with an intercooler as they featured low boost pressure for fast response.
It was used in the following vehicles:
- 1984–1989 Nissan 300ZX Turbo
- Nissan Leopard
- Nissan Gloria/Nissan Cedric (230 PS)
- Nissan GTP-ZX Turbo Race car (Not-Production)
