Does the 150bhp Garrett VNT17 have a rectangular 4 bolt connector to the manifold?

The VNT15 and 130bhp VNT17 seem to have a triangular 3 bolt mounting.

If i fit a 150bhp VNT17, do i need the manifold too.

The car has an inline afn engine with not much room to spare for a larger turbo, so an adapter plate is not a good idea.

What other manifolds will fit, as the 1.8T manifold looks like it would work?

The gt1749vb has an integrated exhaust manifold and wont fit inline engines. 1.8T manifolds wont work either since the flanges are totally different.

The options you have are basically a hybrid inside vnt15/1749va housing or into a certain vnt20 sized housing. Or you could make a custom manifold and get pretty much any turbo fitted there after that :)
