I probably would have considered a Banks "drop in kit" if it was available when I started my project. As it stands, I have all the parts, and have done most of the fettling, I think, using the VW bits. The VW bits are inexpensive, durable. I know of one conversion that was done that worked out. I purchased the Banks NG3 CVJ output flanges as I was purchasing a NG3 from him, and it was easier than chasing that down and having them done here.
