Hi all. I had to replace a head gasket recently and found out the owner before me had deleted the balance shafts. Well while I was in there i also had some oil leaks. You know, oil pan, front case, crank seal, valve cover, basically everything. So when i found out about the balance shafts I was like "Cool one less mod I have to do". After I got it all put back together and running I found out I had really high oil pressure.... Dough 
After reading all the high oil pressure threads something occurred to me. Everyone keeps talking about porting the relief valve. Why not just block off the stock one and install an external oil pressure relief valve. Our oil filter housing has ports that are not being used for anything. And most the time the ports i see are about a half inch. So just run a pressure relief valve from one of the blocked off passages to oil pan. In theory its alot easier and you dont need anything but the valve, some hose, and some fittings. Can even tie it into the oil return line from the turbo.
Parts would be valve, http://cloudfront.zorotools.com/product/full/3EEX4_AS01.JPG 90* fitting from oil filter housing to hose that leads to valve that leads to Billet Turbo Oil Return Fitting Precision Turbo T3 T3 T4 T04 T4 TO4 GT40R GT42R | eBay with this Canton Fitting NPT Toan Adapter Fitting Two 10AN Male to 1 2" NPT Male Tee | eBay screwed into it.
I am thinking of doing this just wanted someone else's opinion, will run me 30-40 $ seeing as I already have some of the parts. Also I dont have to buy or borrow a Dremel, or have to worry about going to far and messing up a good oil filter housing. This will also give me the ability to set the pressure at different ranges to get the desired oil pressure I'm searching for. Last it should be alot less time consuming. Yes
No
?
Here is a diagram that may help...
