Considering oils critical it’s a must spend money on part in my opinion. Increasing oil pressure and flow at low and more rpm doesn’t solve everything, some engine parts like turbos don’t like increased oil.
Amayama ($100 usd plus $20 aud shipping estimate) or partsouq ($70 usd plus $50 aud shipping estimate) using the genuine part number. 15100-74030. Check part number is what u need - no liability on me. Only fits Gen2 sump or Morison.
ATS Racing, $169 usd plus shipping estimate of $60 usd. Basically they have had a different relief valve installed (not shimmed like some refer to as the DIY solution)http://www.atsracing.net/Parts/Details/E-OILPUMP
Take out info from net...
The main seal hole is the same size, pump gears are the same diameters, but the 3sgte is 13mm thick, 5sfe 15.3mm thick.
So on just a pure volume per revolution difference, this would make the 5sfe pump 18% more than the 3sgte.
On top of that, the 3sgte pump gear has 27 teeth, the 5sfe 25 teeth, so that would be… crap, maths on this one is a little harder. About 8 percent more.
This also means you have to run the third gen timing belt, as it has a tooth or two less.
This means in theory you could vary the increase in flow (and therefore pressure) many ways.
You could just swap on the 5sfe gear/gen3 belt for about 8% increase in flow by spinning the 3sgte pump faster.
You could put on the 5sfe oil pump with the 3sgte gear for about 18% increase in flow.
You could put on the 5sfe oil pump with the 5sfe gear for about 26% increase in flow.
Check your tension on timing belt before running engine to ensure components have been matched correctly.
