Yes I understand the need for BB turbos to run a lesser Oil Pressure, and also be watercooled. The turbo going in my car is your standard oil cooled, thrust bearing style. And I also understand the need for a proper oil return as well, no restrictions causing some back up and too much oil built up in the turbo and it leaking past the rings. I have mainly been reading about these restrictors on Tuners (which is why I'm here asking because I question the validity of stuff on there). Some are stating that they are running high oil pressure at times, and they claim it's causing oil to leak by the turbos rings and get into the exhaust housing and blow smoke. And they are solving these issues by adding restrictors to the feedline, or running a -3an vice a 4an feedline. Thanks for the replies thus far though!!

Also about using what my vendor recommends. I do not have much trust left for the vendor I purchased this from. The turbo was ordered about 6 months ago, when I still trusted them. But not anymore, so I would rather not follow their advice. I trust the peoples knowledge on here much more then them.
