Whats what GTR turbo up grade

[exXU1]

Hi Gents, currently doing a few mods in the engine bay, R32 GTR.. Whilst re routing my oil feeds ,water and vacuum lines , i ve become 'kunfooozzed"??? OK who can help me . ( its probably quite simple ) Standing at the front of the car , facing the engine bay, manifold, turbos out. Behind where they were close to the fire wall is a bracket with two lines comming into it and along side it is another sepperate line, all steel fittings that run behind the engine to the intake side.

Now. I Know the largest one ( closest to the block is water ) whats the next two to the right of it. I think the one immediately next to it actuated the wastgates on the turbos ? wuold they be manifiold pressure ( boost ) or vacumm actuated . And the one next that, FK knowS .

I'd appreciate a hand here ye all . :bonk:
