With over a decade of racing experience using the Nissan SR engine platform PRP team has developed a bolt in solution that remedies the weakest link in the SR engine being the oil pump.
With this in mind, PRP has produced a cost-effective way to fix this issue allowing you to keep your engine running longer while pushing it hard. Manufactured from EN26 Billet Steel, All gears are surface ground to perfection then isotropic polished to a near mirror finish. These new gears are significantly stronger than the OEM gears as well as all other aftermarket gear and fit directly into your oil pump housing without modification. There are 2 different options available depending on which SR20 Engine you have
Please note the crankshaft snout needs to be machined with the new collar fitted for spline drive applications, if the original drive is damaged or worn on your crankshaft we recommend you upgrade to spline drive as it simply will not wear, please make sure you select the correct gears to suit your pump. If you are unsure which gears you require please contact us for more information.
