The reason I'm looking for the three bolt manifold is that I'm told that is the best fit for my application. I'm under the impression that the three bolt locates the turbo higher up towards the intake than the four bolt. I know the manifold/turbo setup on say, Jimfoo's AAZ, flat out won't work for what I'm doing.
Mounting this motor in a Vanagon with the factory hardware tilts the motor over at 50 degrees and really limits clearances between the turbo and the motor mounts. Plus there's turbo drain issues, etc etc. But, if I'm wrong and there's an AAZ four bolt exhaust manifold that locates the turbo (only the turbo with the lever actuated waste gate will fit) in the same exact location as the as the three bolt, then I'd be interested in it. Obviously my experience with this stuff is limited, so thanks for the interest, concern, information and patience. Joel
