Increasing the performance of oil pumps? Spring constants

[Bense]

Have any of you ever done anything to the oil pumps to raise the pressure? I know there's a spring with a ball at the end of it that regulates the pressure.

Does anyone have the dimensions of this spring for an H22A oil pump? In particular what is the spring constant (N/m)

I'm doin a project and according (pun intended) to my calculations, an 18% increase in pressure would help drastically

Check out the thread above.

Shimming it is the way to go.

There is no spring upgrade that I was able to find, H22A, F22A/B, H23A, F20B springs, valve relief and plugs are all the same part numbers.

I know. This is uncharted territory.

Actually it's not really uncharted. The washer/shim oil pump thread link that is posted above is the best way to go. That thread is 5 years old and it is based on a thread from 2009.

Just out of curiosity, why is it that you are looking to raise the oil pressure, turbo build?

I was referring to the specific part about replacing the spring with a different spring of different mechanical characteristics. It'd be cool if someone had measured the spring constant on a spring dynamometer / fish scale, so that I could find something else on mcmaster.

Don't need to increase my oil pressure, just my post count because of the rules.

It's like they say not to post just to increase your count in the rules, or something?????

I'll be sure to remember that the next time any CB7 members message me and ask me for assistance.

a proper b/s delete is supposed to bump it up a lot too.

Lol what a douche.

Notice how your counts now 1?

I'm not a mod so I didn't do that.

But yeah, good way to start dude

Insulting other members, especially in this section, is a good way to experience a similar fate, Lachlan. It doesn't matter how accurate your assessment may be.

Fair call, just got annoyed by all the spam. My apologies.

So is there a way to increase the oil pressure? See my oil pressure is well weak and its cause I dropped to a gear I shouldn't have and now the oil light comes on at low idle, and only for a sec after first start up and I've noticed I don't have vtec, well after a few seconds at the rpm hits 6ishk and it's set to go at 5, so I believe I have a oil pressure problem, the engine runs fine and what not, and maybe I messed the pump up when I did that but I'm looking for a solid temp fix. Haha. Please don't tell me my engine is trashed I know where it stands as it is, as I drive it not you. Also it's a f20bdohc.

Bense isn't going to help. He threw a tantrum because he wasn't given special treatment and left.

If you have low oil pressure as a result of over-revving or whatever you did, then it's because of something that is damaged. The oil pump is the most likely culprit, I'd expect. A band-aid fix of any sort could possibly exacerbate the problem that already exists, and cause complete failure. Find and fix whatever you damaged, and you'll restore oil pressure.

Grab an oil pressure gauge and get some numbers. I'm surprised you are taking it up that high if it has an oil pressure issue.

You can do a balance shaft delete to up your oil pressure, but at that point you may as well replace your bearings which are probably damaged as well. Drain your oil and look for fairy dust/metal shavings.
