pro oil pump

[sleepr]

most of you know that you can raise oil psi by shimming the relief valve on the oil pump, I need to know fast how many psi can be gained from a .004 to .006 shims, I guess a better Q is, has anyone on here shimmed a oil pump before?

there is such a thing as to much oil pressure you know thats why its there.

[sleepr]

i know this, but whenyou would want more oil psi if your running looser clearances on the mains witch i am because you can get it to rev a little quicker

Get a higher flow oil pump. Also make sure you seal everything really good. Toyota got metal gaskets for 5S-FE.

i dont want i higher flow pump, i just want to get a little more psi out of the stock one by shimming it

[Pineapple]

You'll need both. Get a Oil Pressure gauge if you shim it. Just to make sure you don't over pressure it.

will do
