DX, why for?

I looked in my service manual and found that the intake manifolds ARE different between a DX and CX. The D15B7 (DX) and D16Z6 (Si) have the same manifold and the D15Z1 (VX) and the D15B8 (CX) have the same manifold. The difference I have found is that CX/VX throttle body is smaller than the DX/Si one. So that is why for one that the intake won't "fit", but that could possibly be fixed with a little silicone tubing. My service manual doesn't give the bore of the throttle body though, so I can't tell you for sure how much bigger it is. It looks a might bit smaller though (like 10mm maybe, not for sure). Anyway, there can always be modification on the tubing, it's just tubing for ****** sake.
