As the title says I’m on the fence on which oil pump gears to use. The car is goin into the shop in about 2 weeks to get an ESS G3X put in with supporting mods. The shop was recommending MMR but I’ve heard mixed reviews. Guys from your experience can you help me out please. Please and thank you. End goal on the car will be about 900ish to the tire. Options are

Boundary
TSS
MMR

I used MMR. Your shop should be able to measure the tolerances to make sure it’s within spec no matter which brand you choose.

I used Boundary. No issues yet. Beat the shit out of it every time it fires up.
