What turbo manifolds form stock cars will bolt up to the 3.0 or what is a close fit? what about the 3000GT twin turbo or the 300Z twin low Psi...

You wish it was that easy, only the Vulcan manifolds will work on the Vulcan engine.

If you have cast iron welding ability then you could modify them to work but the problem is thee is not any room for it. There is a site that shows how you could put a turbo in the y-pipe and them you would have all the room you would need. I wish i could remember the page, i am sure some one else can.

make your own turbo header.
