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.

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)
