Introducing 6 bolt 4g63 straight cut oil pump gears for sale! I've been working on this project for a while now with help from Dustin Leibfried and Kiggly Racing. These gears replace the discontinued oem straight cut gears that were proven over the last 35 years to work for almost every 4g63 build out there but are 20% stronger and have the stub shaft integrated into the driven gear eliminating the risk of it falling off and causing a major failure. These new gears were tested in my personal 4g63 MR2 which showed great results. Oil pressure at idle and to a 8400rpm redline were within a couple psi of each other. Having these gears available eliminates the vast majority of you from needing more expensive options out there. Pictured below is a log of the oem gears vs the new ones and some machining numbers for those that are interested. These are $320 shipped and are in stock ready to ship. There's a limited supply so if you're planning a build in the future, don't wait! Message me directly to order.
