Depending on the turbo, you MIGHT be able to get away with it. If you have a BB turbo, I wouldn't do it. I've heard some people say that you can get away with no restrictor on a journal bearing, but I wouldn't test it. The reason being is that there is a large spectrum at hand when considering adequate oiling, not so much with OVER oiling. My SR20 runs over 80psi @ ~5k, that is more than enough pressure to push out your seals.

I run a FP 20G on my SR and was told by them that I didn't need a restrictor; I laughed and hung up the phone. I say 1/32" (0.031") for BB and 1/16" (0.063") for journal....
