The weakest chain in our 4g93T oil pump system is the OEM powdered metal gerotor gears. This gear were made with cost as the main factor, not performance. So although they can last the entire lifetime of a street -driven engine, it would not last that long for a drag or track oriented GSR turbo. The proper solution for a drag car would be a properly design "dry sump system". but that will cost us an arm & a leg :( .. We result to a more feasible solution. Duratech's billet oil pump gear for 4G9x series oil pumps.
This gears follow the exact dimension of OEM gears.. But due to variatiations in Mitsubishi casting dimensions, the gear are manufactured with a small margin in thickness. What this means is it can provide increase flow to the engine
Made from high grade forged billet steel that are a lot stronger than the factory gears to withstand the High-Revs nature of our performance customers.. This enable a p&p solution for most high Hi-revving/boosted gsr. But like every other Performance parts, they are only as good as the installation process !!

So we ported & polished both the pump's inlet/outlet to increase flow to the engine. And we clearenced & blueprinted the Oil Pump assembly up to our own spec.

Once the pump assembly has been completed, the gerotor gears are generously filled with Lucas Oil's Assembly Lube.We use Lucas Assbly Lube for all Engine rebuilding, bearings, cams etc to prevent premature wear on initial start-up.

| Completed 4g9x Race Oil Pump Assembly + Duratech's Billet pump gears. FTW !!! |
