Im about to do a conversion but i have plug n play wirin looms with mines. Sure wiring wise you need to get some custom stuff made up. Other folk on here will know the score. As far as i know ul need the engine , intercooler , 4efte powersteering pipe i think although i dont know why yet , ecu , exhaust and obviously a turbo if your engine wasnt coming with one. Price really depends of what condition your after. Can pick up engines pretty cheap at the moment though. Hope theres something helpful in there somewhere. Russell
