Hello, I have a 87 Turbo II that is currently going through a rebuild. I am wondering if I should increase the oil pressure from stock. It is not a crazy horsepower build, just a free flowing exhaust, 720 cc secondaries and a RTEK 1.7. If I do increase the oil pressure, should I follow Aaron Cakes tutorial on doing it, or purchase a FD regulator? Also with an increase in this oil pressure (looking for 80-90 psi), should the front cover be shimmed?

Please let me know what you all think.
Thank you!

 

Stock FC oil pressure is good for zinging up to 7500 or so from time to time. For higher horsepower and sustained higher rpms, just install an FD oil pressure regulator. They are affordable and give you the extra psi (and piece of mind) you need.
Do not crush the stock regulator. This is a stupid hack with unpredictable results.

The front isn't a regulator- its a pressure relief valve. If you swap the rear regulator, you can shim the front to relieve around 120-135 psi- test it with compressed air.

Keep in mind the stock FC oiling system rarely fails- so keep you power and driving goals in mind. Don't overbuild the car

 

Thank you for your input! I think I will go ahead and install a FD regulator as it will be up in the RPMS a bit.

 

I was thinking of doing the FD oil pressure regulator in my S5 turbo while I have the subframe off as the pan is accessible. Is there any issues with just upping the oil pressure? l.e. can this be done without shimming the front relief or any other problem? I'm running dual oil coolers so thinking the higher oil pressure will be beneficial with adding extra plumbing and running the oil coolers in series.
