As you can see... it has opening for the water lines (i think)

but they are not being used at all...

And m manifold that i want to keep...

They are nice huh Sydneykid

I'm gonna get all the welds cleaned up and stuff while it's off.

This is what my new turbo must bolt to...

As i dont wanna buy a new manifold... so the turbo must have an internal gate i think ???

[R31Nismoid]

So after all that...

it has the T3 rear housing we worked out with a rather large comp cover .6 A/R

Charaterisitcs of the turbo are it hits 13psi at 4300 or so (it used to make 9psi at 4300 also) and holds to 7000rpm strong.

The turbo spools from around the 3000rpm mark but doest really apply any boost.

So basically i need something that will give me approx 15psi by about 4000rpm at the latest, but at the same time it's gotta be well flowing up high as the car sits there often

That exhaust housing looks sort of large, you could always drop that down a bit. Adj exh cam wheel will help.

As for wastegate, you could get a gate fitted directly to the turbine housing - so the manifold wont need to be modded.
