Pentastar motor

I always want to do a 3.7l that came in the jeep Liberty.I bought on new in 04' and i was also very impressed with mpg the pep and passing.For a v6 with over head cam it was a revere.My only cringe was it was just a 4.7l Benz engine missing 2 cylinders.And there not to much aftermarket support for those motors.I know there are some products on the market but not much.

Has anyone else any opinions on these motors?
