The 6G75 engine is a variant from the 6G7 series with a displacement of a 3.8L in a V6 form factor. Although the engine was placed in luxury sedans, it was quickly adopted by motorsports as one of Mitsubishi’s most powerful engines from the era.

Boundary oil pump gears are 100% manufactured in our Dallas, Texas, production facility. We start by quenching our Chromoly billets from extreme heat and then temper them to a tough indestructible core. After machining, we apply our ColdFlow surface hardening process and complete it to a Mirror Finish. What does all this give you? It gives you a pump with stability over 9000 RPM, proven in excess of 2000whp, with higher efficiency, less friction, and backed by one of the industry’s best warranties.
