It can be done, but I too agree that its' not worth puttiong just the blower on. If you did just put the blower on, depending on your driving style, would depend on how long your engine would last. A 3.8 N/A engine isn't strong enough to hold the boost for very long, atleast of the SC's blower. It can handle the Vortech alot better.
I agree, I would just get an SC engine over getting a Vortech kit. Mainly because you could re-build the SC engine before it went in and can hold more boost.
