Turbo Oil Inlet Restrictor

So, I think I'm killing my new Borg Warner turbo. The balance shafts are removed in my new motor creating higher oil pressure. I noticed that my car is burning a little bit of oil and didn't think too much about it until I looked into BS removal and high oil pressure killing turbos. My turbo oil line feed comes from my oil filter housing therefore it has even more pressure than it would if it was being fed from the head. I called a few places and they all agreed that I need one but, can't tell me where to get one haha.
Anyone know where I buy one at? I'm not sure what size hole I need but, I know the fitting needs to be a 1/4" NBT fitting.

All you need to do is put a smaller diameter outlet on the turbo return line and it'll keep the oil from shooting through the turbo too quickly. Or is it getting too much oil on yours? I'm kind of confused as to what the problem is...
I know extreme carries em. Here is one for a Garrett/PTE turbo... http://www.extremepsi.com/store/customer/product.php?productid=18920&cat=336&page=1 Maybe give em a call or look around some more on there to see if you can find one for your turbo.

The problem is that there is too much pressure going through the turbo and it is prematurely wearing. Oil is also leaking past the turbine and being burned. A smaller outlet would most likely increase the pressure inside the turbo from the oil. Most high end turbo kits come with an oil inlet restrictor like many of the GT series kits. Some restrictors are even built into the inlet oil line fittings. Alot of inline oil inlet filters also have built in restrictors. My turbo kit did not come with a restrictor.
I already checked extremepsi. They don't have any 1/4" NPT for my application. I called and talked to one of the techs there for a little and he agrees I need one but, he isn't even sure where to get one at. He mentioned ATP turbo and I looked into it and found this http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-OIL-021&Category_Code=ATP-OIL1 I'm going to call ATP monday and talk to them to try and get some more information.
Anyone have knowledge in this area?

If you plan on installing a new turbo anytime soon I would definitely read over this. I think I'm going to feed my journal bearing turbo from the head and see how it goes.

It depends on the PSI limits specified by the turbo manufacturer as to what restrictor vs. what oil psi you'll need. I feed a PTE journal bearing from the OFH with my BS removed.
