I'm basically doing the slowest engine build ever but am slowly gathering parts. I've been offered a good deal on a .63 Tial stainless vband housing. I was planning on using either the TSR or PagParts manifold which are both vband, just for easier fitting. PagParts do a .72 vband housing but I was speaking to a guy running GTX3071s on a C5 RS6 and he recommended I go for the .63 for better spool on the road? I don't really want to be revving madly high. Any ideas? The turbo currently has a T3 .82 vband outlet housing which I'll flog if anyone needs it? Andrew?
