newb with a manifold question

[GonzoGTR]

New member here. I'm importing a 99 stagea 260rs and it should be here in about 4 weeks. During this winter and spring to early summer the plan is to do a single turbo swap (gtx35 or a pt 6266) in the meantime i hope to enjoy it for the last month and a bit of nice driving weather around here. I was thinking of doing exhaust manifolds and possibly turbo elbows and an exhaust.

Anyways these are the manifolds im thinking about getting as they are at my price point.
So my questions. 
Now what I can't figure out is what are the extra pipes? There's 2 on each manifold. One is a t2 flange? One is for an external wastegate? 
Whats the other one for, whats the purpose?
Can i bolt the stock turbos onto them?
Thanks

Well, one is definitely for an external gate, but I couldn't tell you what the logic behind the other square flanges are for.  They could be to run some bizarre quad turbo setup (AS IF there's enough room for that!), or for some crazy exhaust pressure balancing pipe.

I'd think that just because they're at your price point is not necessarily a reason to buy them.  I would not be planning to do the work involved in removing the turbos from an RB26 unless I was forced to.  It's a tedious task, and those manifolds are unlikely to reward you with anything in the way of extra power.  If you're planning on changing to a single anyway, I'd be looking at spending money on things that are worthwhile, like a full set of rubber hoses (coolant, vacuum, etc), timing belt, water pump.  Possibly ignition coils.  All the boring stuff that the poor car is likely to need after possible years of neglect/use/wear/heat.  Or brakes, or suspension bushes, or a fuel pump or the list goes on and on and on.

No point in changing the manifolds if you are going single. Waste of money which would be better spent on a quality manifold for the single. I attach my pic of a quality manifold with a GT3540 but I would support your getting a better twin scroll turbo.

Yeah its a balance pipe flange.

Secondly, as you haven't received the car yet i can somewhat understand why you think you could change the manifolds easily. However you cannot. It is a very, very tight space to get to stuff with the engine in the car. As someone who currently is sitting at 8 months without a working skyline, take my advice: get it, do the basic services, drive it, enjoy it in the warm months you have, and figure out any other little issues you want to fix. Then go single turbo.

So you can run four turbos on it

Thanks, I appreciate the answers. I should of realized how tight and how much work itd be. A bit pointless as iI'll be swapping and a waste of money as gtsboy and kiwi said.

I had thought of coils and a new bushings kit, i had thought that letting the gases flow better would be cheap and easy... I had  93 180sx that i imported with 93kms and near stock  that I sold to fund the stagea. I have a 2 post rotary lift at our farm, so first thing i did was lift up the 180 and do a down pipe, let tit flow and everything else was really easy to get at. I forgot its a bit more tight with the rb in there.. I think I'll focus on what you listed.

What about turbo elbows? If i can get them cheap enough, are they as easy to get to on the sr if i use a hoist. Are they worth it? I might be able to get a return of my money for them when i do a single swap

Dumps (or elbows) are turbo off job. Don't bother if you're going to change the setup.
