for me costs were similar between a twin turbo build (with quality new turbos, waste gates, bov ect) and procharger for my 512", turbos make more power, boost control is undeniable and seat of pants feel seams cooler.... procharger takes up less space, no fab work, or oil feed/return lines to mess with, still sound cool
