High oil pressure regulators

These all clam to increase the oil pressure anywhere from (90-120)PSI. OEM is about 60PSI.

Just wondering if anyone has changed this out?

P.s. engine is intake/exhaust ported

 

Yep...


work as advertised. I have used the Maxmart one... and I have an adjustable one in my REW


You can also modify the stock one if you squeeze down the spring to increase the spring rate.

You also have to shim the front cover pressure relief valve as well or it will become the limiting factor for increased pressure

 

Awesome! Did it help keep temps down? If so how much? Any brand you'd recommend. I'm thinking the re-medy (Go's with water pump) from mazmart. Just not sure because its has to be 1/3 the price for a reason.

 

It will work fine. Basically it is just a modified stock one. A FD one is higher pressure than a RX8 as well. I just cant remember what the pressure is for them

I doubt that you will get a lower temperature.... it I'd mainly to have higher pressure for more bearing protection

 

It helps with bearings and cooling side seal springs (oil is sprayed inside the rotors, more pressure = more oil sprayed).

This is purely a peace of mind modification that should help with long term issues. Any short term benefits you see will be entirely inside your own head.

 

Thanks for the help guys. Sounds like i have one more task to do before throwing the engine back in.

Just wondering any DIY's forums on this? I wasn't able to find anything really untill I posted this. Then a related posts few popped up at the bottom.

 

It's very simple...

Remove stock rear..... screw in new one....tighten to spec

Remove front one.... add shims ...re-install

That's all it takes...

 

Essex Rotary actually had a little video of the process. Surprisingly very simple.

Thanks for all the help Dann
