The 5.7 hemi isn't really worth the money for the conversion from the 3.6 Pentastar, especially if you're coming from a supercharged Pentastart. 5.7 Hemi only makes about 230 hp at the wheels in a Wrangler. Only about 40 hp more than the stock Pentastar, and substantially less than a supercharged Pentastar. That would be a $20k downgrade from a supercharged Pentastar. If you're going to do a V8 conversion, go for a 6.2 LS or 6.4 Hemi.

I agree that a single catch can (on the make-up air hose! not the PCV hose!) is perfectly adequate, to reduce oil vapors going into the intake during high engine load/boost conditions.
