We also were able to get Aisin OEM pumps this time, so it's the same pump as before, but costs $40 less!

Brand new Toyota pump, blueprinted internally, moly coated gears to decrease the spacing between the gears and offer smoother operation, and also shimmed to make higher peak oil pressure. This mod really helps the oil pressure at idle, and at low engine rpm! No other mod to the engine will make a more noticeable increase in oil pressure at idle, and that is where this mod helps to improve the engine's reliability and lifespan. My built 7M project a few years ago had this pump upgrade, and it made about 18psi of oil pressure at idle when fully warmed up, running 10/30 oil. My previous 7m made only about 7psi when warm, even running 10/50 oil.
