Oil System Components
The oil system keeps your engine alive. It moves oil from the pan through the pump, filter and passages to the bearings, cams and other moving parts. It also holds enough pressure to keep a protective film between those parts. Enthusiasts upgrade oil system components when they add power, raise the rev limit or spend time on track, where stock parts can be pushed harder than they were designed for. The usual goals are steadier oil pressure and more consistent protection under hard use.
Right now we have 1 product in stock in this category, from Boundary. It is the Boundary Nissan VQ (All Types) VHR Shim Kit (10/20/30 PSI) - 3 Shims, a shim kit for Nissan VQ engines. Shims like these are generally used to adjust the preload on the oil pump relief valve spring, which changes the point at which the valve opens.
Confirm the part matches your exact engine family before you order.
Decide how much pressure change your build needs, and check with your engine builder or tuner.
Think about supporting parts, such as an oil pressure gauge, so you can monitor the result.
Follow the manufacturer's instructions closely when fitting internal oil system parts.
