dude go here
i personally have a Vf22 turbo (subaru style flange). you can buy these turbos cheap as and convert the back housing to suit laser type flange. if not you can do what i did and make a custom exhaust manifold and change it to subaru flange so you dont have to muck around again
the IHI turbos have a few advantages the biggest being that they are more compact than the garret alternative which means they are easier to fit and plumb.
