Hey guys pretty new here.

So i have a 03 xb9s, hawk exhaust,race tune, and kn filter.

I have a 06 xb12ss engine sitting in my garage, with throttle body, front and rear sproket, and ecm.

Is this a direct swap into my xb9? I read i just need a new belt. Is the belt tensioner the same from a 9 to a 12?
excuse any ignorance, love the site
