2bar of turbo pressure?! WTF! if i see that on a factory gauge, **** me! whoa!

Different Ways of looking at Boost..
There are two ways of looking at 'Boost'.
On is the 'absolute' pressure above a perfect vacuum.
In that case, a pressure of 1 bar is about atmospheric pressure (My urq shows boost gauge at '1' when the motor isn't running. Goes below 1 when a vacuum in the intake, and above 1 when boost is happening).
In this instance, intake air pressure is indicated in 'bar', with a bit of an implication that it's an absolute number.
Most ECU MAP sensors look at the absolute pressure in the intake, as they have to deal sith both vaccum and boost situations.
Then there is the 'relative' way of looking at boost:
In other words, how much 'boost' you get above ambient atmospheric pressure.
That's what a normal pressure guage would indicate if connected to the intake mainifold. For some reason, usualy given in 'pounds of boost', rather than in bar..
So in otherwords, a guage indication of '2 bar', would imply the same thing as about 14 lbs of boost.
2 bar, as in 1 bar of atmospheric pressure, plus an additional boost pressure of 1 bar. An additional '14 psi' as it were, above atmospehere pressure...
Totally confused now? :-)

I see something.
There's no hose on the breather port of the valve cover. That's supposed to plumb back into the intake tract before the turbo.
I supposed the most obvious thing that it's "missing" is the original head. Perhaps it had the recall done where they pull the alluminum engine.
