Oil pump shimming

[enjoi.this]

Ive searched around but have come up with any info on shimming oil pumps on 7mgte's. Is this a worth while mod to do and what all is involved in doing it? My crank bearings are to arrive on friday so id like to figure it out before then. Any info or pointers on this would be great.

Thanks,
Chris

Its worth the 30 min of parts run and install.

anything to help improve the oiling system is worthwhile imo

Awesome, thanks for the info warpath. 5mm shims here I come**
IMO the second link you posted should be a sticky

^^^ Didn't stick it, but did move to the oil section so it will be easier to find.

I remember seeing pictures of exactly where to put the shims. Does anyone have pictures or can someone post them? I just started with my motor swap and I've been out of the game for a little bit.

There's a nut/ bolt thing at the base of pump. It's spring loaded. Shims go in front of spring.

So between the nut/bolt and the spring or between base of the pump and spring? Just to clarify.

I assume you have it out. See the bolt deal, if you got the right washers, they should sit perfect inside the bolt. Then spring then tighten down. Make sense?

No, I dont have it apart yet. I figured thats where the shim should be placed. Just wanted to clarify before I get to it. Its nice to start and finish a job quick and efficiently. Thanks for the pointers btw

Sure thing. Post pics on progress.

Here is a pic where the washers go.

Is this a good thing to do even on the N/A's??? I'm doin a HG job on my brothers supra so while everythings out I might as well do it. Will it lower the life on the oil pump???

Cant see why you couldnt on a NA. If your oil pressure was lower then spec shimming it to retain factory pressure would be good. It is logical that making the pump push more pressure could shorten its life, but its really only such a minimal amount. The pump would still outlast the life of the engine anyways in most cases.

Thank u

I took some pics of shimming the pump. Pics are pretty straight forward and self explanitory. The shims I used were (3) 6mm washer I believe. They measured out to about 4.86mm and fit perfectly inside the spring retainer bolt. One thing to be careful of is not to bend the pick up or outlet tube when undoing and retightening the 3 bolts.

Your post needs a sticky!

It would sure stop people like me asking about previously answered questions

While you got your pump out and shimmed. Get an Arizona performance oil supply line kit to help with that increased flow.
