Aftermarket parts including crankshafts, pistons, rods, engine blocks and more—we all use them—but what goes into deciding what is made and what material is used to ensure you are really getting something better than OEM, and how do you know if you need such an upgrade?
Christian from Nitto Performance Engineering gives us some insight into these topics and more, with examples including high-volume SR20 oil pumps, RB32 Torrington bearing upgrades, and ACL custom bearings, as well as how 3D printing is used for research and development.
The difference between Sine Drive and Flat Drive oil pumps is also covered, as well as some of the power levels that see engine builders move from OEM to aftermarket parts and materials, including 4340, EN40B and EN26.
