6G74 GDI

The gasoline direct injection version of the 6G74 was launched in April 1997 as the first GDI V6 engine ever produced. It differed from the basic 6G74 in many ways apart from its unique fuel injection system — it had a crown-curved rather than flat combustion chamber, upright intake ports rather than angled, and a 10.4:1 rather than 10.0:1 compression ratio. Mitsubishi claimed 30% better fuel economy, a 30% reduction in emmissions, and higher power outputs than Diesels.

The 6G75 is a 3.8 L (3828 cc) version with 95 mm bore and 90 mm stroke. Output is 230 hp (172 kW) at 5250 RPM with 250 ft·lbf (339 N·m) of torque at 4000 RPM. It has forged steel connecting rods.

Applications:

* 2006-present Mitsubishi Eclipse
* Mitsubishi Galant
* Mitsubishi Montero
* Mitsubishi Endeavor
* Mitsubishi 380 (175 kW @ 5250 RPM with 343Nm @ 4000 rpm)
