Let the man do what he wants....its his car and his money and its also hes responsible for maintaining it..
All these suggestion of "dont do it" will not help...but he wants to do it and determine thats why hes asking for help..he did his own research and found out his own info..
All we could do is wait and see how it turns out..
Like we all said...Goodluck with this mod path...post some pics,vids,chart...and so on...when your done
