Pop Off Or Port?
#1
Since there's been so much talk on mid-pipes and creep/spike, AND I am getting creep from my mid-pipe I figured I would ask the question.
Is it better to get a pop-off valve or port your wastegate? I figure a pop-off valve is kind of like a secondary safety net because it really dosen't solve the problem. Your turbos are still spooling (x) boost but only (y) boost is getting to the intake manifold right? So isn't it bad to have the stock turbos working that hard all the time? Where as if you port the wastegate and you set say10lbs of boost they only work for that 10lbs. Not like the pop-off solution where they work for 15lbs but only 10lbs get there.
Am I getting this right? If I am does it really make a difference?

Just an update. The guys at Mazdatrix say to just get a bigger pill for the "short wastegate hose". They said to get a .0067 pill. They think its the 67 holley jet. they said it will limit you to 10-12lbs of boost. Nice six dollar solution if it works.

I can set you up with the know how.
All you need to port is the bits. http://www.eastwoodco.com/aspfiles/search.asp
Once you get that and you disassemble the turbos. You trace a 1/16" line on the inside ofthe wastegaet hole and cut out the material.
Thats about it.
