Check the compression first thing. Then stick with a 50shot at first and see how it holds up. A Wideband wouldn't be a bad investment if you plan on running it a lot. It will tell you if you need custom tuning at least.
My honest opinion tho, since Ive done the Juice route a couple times. It's fun, YES. BUT, you have to fill that bottle to have fun and it can cost $50-$80 a fill!!! Save a few more bucks and build a turbo kit, or buy a used one. Its readily available fun once it's on!
