Well because I am guessing you are ready have a manifold made up for it.
What kind of turbo was it: Who makes it. What flanges and housing sizes.
Is it water cooled? Being vague never gets you anywhere when you are asking for things.
And are you sure you cannot just rebuild it, or is there wheel/housing damage? And still, the price of replacement wheels, rebuild kit and balancing usally is much cheaper than a whole brand new or used turbo, and you know it wont fail.
