Ok I am lost.. Is it ok to just run a 0.35 restrictor on the turbo? Or do we need to buy an inline filter?
If it's recommended that I buy an additional filter can you guys drop some info on them. With the forced performance one can it only be used with -4an lines. Do they inline filters require any additional parts for installation?

I'm not sure; I've never run inline oil fiters on any of my previous feed setups.

Just to follow up on my first post. I told the guy at precision that on my gauge at the turbo I had 90 psi steady from 4k up with a -4 line. I asked do I need a restrictor and exactly how much pressure does the turbo need. I told him I'd make it so it was exactly what they say it needs.
His response was ... well I don't know. They don't need a lot of pressure but they need a large volume.
I said OK so does it need a restrictor?
He repeated the same thing and after 25 minutes of this I got pissed off and hung up and still never got an answer.

I've had a similar conversation with Precision. For the record, I run a BB 6262 with two restrictors, .35 and a .32. With just the .35 I still had smoking issues, after I added the .32 - no more problems.

You should call and ask to get that 25min of your life back. You may have been on the phone with the gentlemen seen below:

My feed is quite short (coming from the vtec oil pressure sensor using a banjo bolt/-3 AN to the turbo; the .065 restrictor is threaded directly into the turbo, then a 1/8--> -3 AN double male fitting is threaded into the restrictor)
