No need for a kit. If you have an intercooled charger the injectors that came with it are more than up to the task. You get a 1 size larger lower pulley and install it. The belt tensioner has enough leeway for the current belt.

If its not intercooled, I wouldn't consider adding boost.

Your risks with more boost is vastly increased air intake charge temps and an engine which goes "boom." The reason why the non-intercooled Roushchargers have 6lbs of boost is not because of injectors, but rather that you can't run more boost without cooling the air. If you want to run more boost you're going to need either water injection or an intercooler upgrade.

Its cost is going to be a few hundred dollars. I can't tell you much about it... not an expert with it, but I do know it decreases intake air charge temps and allows you to run more boost. Its been around since WWII, proven technology but you need to keep the water take full.
