I use the 0.4mm restrictor on my S14 ball bearing turbo.

I hope you mean 0.04in? .4mm (.015in) is smaller than any restrictor I've seen.

I was thinking about going down to a 0.04in. I'm currently using an unrestricted 4AN braided line and a .06in restrictor and there's a lot of oil. Going to take my turbo apart before buying anything though.
