Like f150phule said, there's a lot more to it than just bolting it on and viola, you're done. To get it tuned, better plugs, fuel pump, new injectors etc, you're probably going to be investing more in the kit/upgrades alone, than the truck is actually worth.... but hey, to each his own.
Also when you go supercharged, you're welcomed into the lovely family of premium gas. The way they're talking, gas could reach $1.40/litre for Regular gas ($1.50-$1.55 for premium) by the summer... something I certainly wouldn't be looking forward to if I was currently supercharged.
But hey, if you have the money, the time to do it and want to be unique, they I support you... you'll certainly seperate your Ranger from the rest of them! :icon_wink:
