The 3.0 L (2960 cc) VG30ET was available in early production with a single Garrett T3 turbocharger (6.7 psi) and a 7.8:1 compression ratio. The USDM version produced 200 hp (150 kW) and 227 ft-lbf (308 Nm). 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). In 1988 compression ratio changed to 8.3:1 and the turbo changed to a single Garrett T25 turbocharger (4.5 psi) to reduce turbo lag. No VG30ET was ever factory equipped with an intercooler as they featured low boost pressure for fast response. We can repair the VG30ET engine. Call for an estimate today!
