Help convince me to go BB in my Duster?

Not sure. You need a distributer and a box.

I'd recommend the pro billet dizzy and the digital 6 box but any box with a rev limit will work.

I'll put it on my list when I get home haha, so something like this?

or did I just pick top of line ones, are there cheaper options?
