I been fallowing this tread for a while now, can't wait when final product will be finished (I am not 100% on board, so I will wait and see what evolves). Just have a quick question: Initially the turbo suppose to be easy install with small boost of up to 5 psi or so with quick installation and removal just in case there is a smog requirement etc., with optional installation of the intercooler. Now I see in wonders in direction of more complicated setup with water cooling system which in my eyes adds complexity to the system. Am I looking at this setup wrong? Are those extra parts, and options for more advanced setups at extra additional cost?
