I love this thread however, and it's also very interesting to read all the mixed reviews. Personally to those who are bashing on the RB turbos because of their less peak output than the singles, you have to remember these turbos are simply a direct swap turbo meant to be utilized with stock manifolds and housings. Of course a single will have a higher peak number but that isn't what the point here is...
Mad respect for OP and progress, not to mention the tune isn't finalized yet. The only concern I have is with the head, I would assume that the better flowing head would be giving the car a better top end? Also I thought the car would be able to keep revving past redline a bit with that head?
Like to see more results and progress though
