    Depends how much power you want. Eveyone here will try to push supercharged or turbo but there are boltons mods for n/a 3800's.

    But bolt on mods for N/A vehicles are not worth the $$$. You need forced induction. End of story.

    You don't NEED it. for the average person who doesn't want to heavily modify their car, and just wants a bit more pep, NA bolt ons can do just that, and really feel like they wake up the car.

    If he actually wants to make some decent power down the road.. then yes it needs F/I.

    Fair enough. Mild mods to the NA motor will certainly make it feel more peppy, but if you want actual power... Then blower or snail are a must.

    Snowtheif has a SSM90 set up for sale you can buy! Easy way to bolt on a blower.

    Intake (make your own), HV3 insert (ZZP), ZZP dp., shift kit, and a tune (overkill).

    No, he said Gen 3. (vs. Gen 5) referring to the supercharger.

    So you would just have to make sure you sourced a gen 5 SC when you put your kit together.

    I assume that LIM would bolt to the series 3 heads/bottom without issue. I could be wrong. Definitely a question worth asking at that price!
