Yes, its got an SSQV blow off valve that is 'plumbed back' so that you don't hear the psshh noise. It's illegal to have an atmo vent BOV in australia, and you may as well give yourself defect fines if you drive on the street with it making the pshh noise.

I run stanza castor arms that are machined down to the same length as 1200 ones.. They are thicker in diameter to the B110 ones. It's possible that bakkie ones have increased in size, due to the increase in engine size. by machining them down, I can modify the castor by using
washers on the eng of the castor rod, but with large diameter wheels, there is not much room for adjustment.
