This intake manifold definitely looks a bit straighter from TB to back of the engine than older NA6 versions.

Not only bore hole sizes are different between the NB TB and the NA6 IM, the centers are offset from each other.

There's a problem, but another gasket can fix this.

Note that we had to slot one of the holes for the NB TB to mate to the NA6 IM. A nut a bolt will work here to clamp everything down.

It seems the JDM B6 has two water ports that connect with the intake manifold.

Though the gasket has holes for both water ports, both USDM NA6 and JDM NB6 intake manifolds have the trapezoidal water port blocked.

Both manifolds have the circular water port to allow coolant to flow to both the NA6 and NB throttle bodies.

Backsides of the JDM NB6 (left) and the USDM NA6 (right) intake manifolds. Interesting that the runners on the NB6 IM is more squared off than the smoother wider radius of the NA6 IM's runners.

Side views of both JDM NB6 (left) and USDM NA6 (right) IMs with NB throttle bodies mocked up. Note the longer and straighter approach to the plenum from the TB for the USDM NA6 IM.
