Nope, no adapter plate. Um I wish I could tell you what turbo it is but I myself do not even know and the guy that built it won't even let me have a hint. Not laggy on the street at at and really starts to spool at 2000 rpm. Boost runs up to 70 with it and it gets there in a hurry. I didn't want twins when I built this truck, I was trying to be the most powerful single turbo truck on #2 only. I think enterprise did a great job at getting me to that level, I can't say it is the most powerful at this configuration but I can at least hope so. My guess is 700 +/-.
