Yesterday I clocked the turbo and checked the actuator: feels like a 7 psi unit.
I also began to weld a new manifold to head flange because mine is warped, and there's a little leak even whith a new oem gasket..
The only issue: oil line.
I need to connect somehow an 8mm copper pipe to the restrictor.
This is what I could find

Terrible, isn't it?
And heavy as hell.

Yes, if you watch the first two pages of this topic, you can see my feed line.
Sixshooter: I know that... the restrictor itself is brass.
I'm finding a different solution, but it's difficult to find npt stuff in Italy

Now, first impressions: it feels slower over 5500-6000 rpm at the same pressure of the chrubo potato, but well.. it's very very funny to drive!
first two gears are just a spin button, the third gear spin the tire a little bit, but enough to false the virtualdyno log (around 270hp at 210kPa)
Now, time to tune this... thing.
I'm in doubt about the advance table: I've modified (internet inspirated) my table this way

The ties... they comes with the wrap
News: I tried the new advance table for like one gear, and it knocked... back to the previous one for now.
I also destroyed the compressor wheel, now the turbo is at the rebuild shop
