Tomei do NB8A and earlier cams. They don't currently have a proven NB8B cam, neither does Maruha. Maruha has had a cam released for an awful long time now...but still barely a dyno chart or any proven results. I'll likely go down the path of an NB8A head and cam set with a Haltech when I move onto a prod sports level N/A motor.

Maruha do have a cam for the Nb8 SVT engine.

Beck on CR.net has an NA with a fully worked SVT engine, including Maruha cams.

Find someone who's done before/after tests on the F-cams for an SVT motor. You'd expect those demo cars to make decent power just because of lightened bottoms ends, head work and ITB's. I'd like to see what difference those CAMS make to a motor with bolt-ons and what the power band is like. I had an awful hard time finding anything useful when I was looking hard at them last year.

No, as in the brake booster still requires a vacum...how does that get intergrated into the ITB assembly?

It just has to be from behind the throttle blades to get vacuum. It won't be as good but I think CT had some experience getting it working on his old N/A racecar.

There's a vacuum line from underneath the ITB unit.
