OFH question and oil cooler setup

[Beckholt99GSX]

So on my 99 7 bolt I bought the EVO III OFH so that I can run an external B&M cooler such as the one that STM and extremePSI sell. My balance shafts have been deleted and originally I was going to use my factory OFH, but plans changed since the factory one sucks!! I was going to port the relief port in the housing and use it so my question is will the relief port need to be ported with the EVO III housing and an external B&M cooler? Or will the cooler and large lines (feed and return) be enough to keep the oil pressure from being sky high?

I would save porting the OFH until you know what your actual oil pressure will be. You can always pull it off again if you need.

I'm also the one that doesn't believe in porting it at all....
