Thats alot of money for that kit! i have that same manifold and it works fine on my car, i needed to do a bit of grinding and clearancing etc though you can get them for much cheaper of ebay germany and suchlike; http://cgi.ebay.de/Turbokrummer-G60...ile_Zubehör&hash=item35afab91b1#ht_2814wt_716
Nice find there I think thats quite good for the price tbh. Still thinking about this 8vT setup, might have to start building it soon
