4G63 Ball Bearing Gerotor Oil Pump

It's no secret that the factory oil pump is basically the Achilles heel of the 4g63 powerplant. We've set out to create an affordable, convenient, and effective solution to the failure-fraught stock oil pump. We started by throwing away the current external gear pump design for a much more suitable gerotor setup. Gerotor pumps have been proven time and time again in motorsport so there was no need to reinvent the wheel here. We designed a rotor set that would fit within the space constraints of the factory pump location, yet still flow up to 50% more than the factory pump. Along with this, we included replaceable wear surfaces inside the housing. In the event of a catastrophe, the pump is fully rebuildable with small, affordable parts. After that part of the issue was solved, we needed to attack the problematic support design for the stock gears. The oil film that the stock gears ride on is all well and good until you throw side loading and oil cavitation into the mix. This is where t
