Smoke and blow by in a na motor can come from valve seals (simple and cheap to repair), valve guides(simple to fix, but costly), rings... Ip timing, chain wear, headgasket...

The 2.5 motor, both na and turbo will bolt up, and fit in the car... The 3.0 will bolt up, but fitting is another story... A 6 cylinder did come in that body in gasser form...
