Vacuum source for Brake Booster

[RETed]

I just checked my Zenki FC turbo...
The brake booster fitting is on the surge tank of the upper intake manifold.
It's offset towards the passenger side of the car facing the firewall.
This is for US-spec engines.
It's basically the lowest fitting back there.

For J-spec upper intake manifolds, there's a short banjo to pipe fitting that comes off the lower intake manifold right over the turbo.
This is to compensate for the RHD design which locates the brake booster on the opposite side of the firewall.
