It's cool to get some definitive information out of this thread other then the ~6hp mentions that I have run across. I have a Exhintake cam that I will be putting in that I just picked up, as well as a aftermarket header and 2.5" and adjustable cam gears. Hopefully with supporting mods I can maximize the modification.

Now 2 follow up questions:

1) [without any previous searching] As mentioned, what is the expected gain/improvement by doing the 5* cam adjustment?

2) It was specifically stated " If you're staying NA this..." I have found no supporting evidence that it will be a negative mod for FI, which I intend to upgrade too later, so is there a reason that it was mentioned specifically towards NA drivers?

Thanks!
