Bharat Aluri

Hello Everybody, I bought 2015 Journey Crossroad 1 week back. and I would like to know whether I can replace 8.4 with 8.4N, i tried to understand the above discussions and I found little helpful and I would like to know what parts I need to change , and what parts I need to buy extra and how much approximate labor cost it might be. and Any feedback after upgrading will be appreciated? Thanks, Bharat
