I have read many post about people putting together their own turbos using the stock turbo. I currently have a turbo from ATS on my truck (aurora). No complaints about the turbo; I can run the BDDL on extreme and barley reach 1150* pre-turbo, but my problem is when I put on my TST I can not use the full box. The ATS turbo is a bolt on turbo and I was wondering if anybody is selling or making piping (and instructions :-laf ) to use my stock turbo and the ATS turbo for twins. I don't know a whole lot about the twins setup, so feel free to take my thinking down a peg or two. I know that I would have to stud the head and o-ring it, but I don't know how to do that either. I am still in college so don't have a lot of mon' for a new set of turbos, but still want to have the fun. I would appreciate any advice you could give me.
