Default Oil feed restrictor size

Ok, so after lurking around in quite a few threads I still can't figure out what the deal is with restrictor sizes. Some claim they don't run a restrictor, some say its absolutely necessary, etc etc. Can't find a general consensus.

I got a Godspeed gt30 chinacharger.
It is oil and water cooled. advertised as "wet float bearing" whatever that means.
Here is the link:

I just recently purchased an oil feed line with 2 restrictors claimed to be made specifically for this turbo:

One is for .8mm (for ball bearing turbo's)
One is 1.5mm (for journal bearing turbo's)

Since I don't trust any info I see on ebay what do you guys recommend I run? The smaller or the larger, or a completely different size restrictor altogether?

run without one, and if you need one, start with a .125" pop rivet trick and then the 1.5mm (.060") restrictor fitting.

Wet float bearing = journal bearing.

I ran without a restrictor using a -4an feed line and I got a fair bit of smoking at idle and big puffs at WOT. I've also heard of people not running one and being fine (corky for instance recommended NOT running one).

I agree with the Brain. Try running without one and see how it goes. If you end up needing one, my advice to you is to run down to your local hardware store and pick up a 1/8" pop rivet and drop that bish in there. Works great.
