RB25DET Greddy Copy Front Facing plenum pipe work

I know there is a DIY thread about this but the pictures no longer seem to be there, I just had a few questions on installing a "Freddy" manifold onto my S2 RB25DET which is completely factory otherwise.  

So my questions are: Can I connect the turbo water feed coming around the back of the block (A) onto the Tee coming out beside the thermostat spout (A) or is (B) better to use?

Can I just block off that rear Tee (B) with a bolt clamped into a short hose otherwise?

Does the other pipe coming out of the AAC valve (C)  go into a bung welded into the boost piping before the throttle body? And does the rest of the piping for the idle valve look correct? 

Is it true that if I'm putting this engine into an R32 Sedan, that I'll need to change my clutch master cylinder to the shorter R33 master cylinder to clear the new manifold?

Cheers for any help

The appropriate response to your post is, why are you installing a forward facing plenum on a stock car?

There are plenty of cars running in excess of 300rwkw with a standard manifold. This exercise is pointless and a lot of work for basically no gain?

 

Edit: credit for the detailed and well-worded post.

Yep definitely not expecting any gains from this I just wanted to tidy things up, make spark plugs more accessible etc on the engine while its still out of the car and on a cradle.  I'm swapping this into a RB30E powered r32 so I'll be adding a fmic, alloy radiator and fans so I want to plan out the best route to run the boost piping and where to hole-saw. I'm retaining the stock throttle body using an adapter so It'll be sitting even further forward.

Once I get her running and legal, then I can continue saving up to chase bigger numbers by doing hotside and injectors with it being ready to take topfeed injectors with this manifold.

Yes you will likely need R33 M/C to clear manifold and a longer throttle cable.

Can confirm no power gains. And need to change clutch master. Also id advise getting the throttle body to suit rather than the adapter as if your keeping the battery in the stock position you need all the room you can get for the cold side pipe

Thanks for the replies! Is the cold start pipe where I want to weld a port on to the intercooler pipe so that I can run a tube to that port coming from where I have labeled "C" on my picture of the AAC valve? 

Will the clutch master still be a problem even though I've installed the manifold with the engine out of the car? Ill start hunting down an R33 clutch master by the sounds of it. 

I was planning on relocating battery to the boot to give some flexibility on intercooler piping location and maybe have some room for a catch can or something like that.
