Its starting to look like my next project. I havnt sold the BD kit so i think im going to do the 66-74, which is the biggest i can go with the s300 frame. Should still be a nice turbo to run.
last time i talked to htt they had told me with the stainless housing they could go bigger than the 66 but i dont know i want more than the 66 but still need to be able to tow the fith wheel , i'll probable end up going with the 66
i thought they said it could be a 71 with the new housing but wasnt sure wich wheel he was talking about it was a quick discusion i figured in would talk more when i had the $
