Got my ATk hp24 in April 2012, my daily driver 3sp auto 31s with 355 gears, better fuel miles, have 12,000 miles on it so far no problems. Happy happy with it, when I need to pass someone I leave them sitting still, wished I did this when I got my wrangler. Fun to drive now , I do have a boredout throttle body, borla header, highflow cat. & muffler . Can't say anything negative about it, just glad to have it!
would it come with the valve cover and header by any lucky chance? if not what should i look for?

It does not come with the valve cover or header. The header i like is the one made by Borla. They fit very well and a very high quality. As for the valve cover any of the stock covers or aftermarket will work for the year of motor.

What parts do I need to buy to make this engine ready to drop in and start up. Also how much boost can the engine handle.
Stephen the Wheel Man from on
Other than standard parts off your old motor. larger injectors, throttle body, header and exhaust system larger.
They say they can handle up to 20 pounds of boost.
