@RS8 I'm not planning on chasing HP with this car and the 630s are recommended from various people. I am going with a 5 bar regulator while I'm in there since that's pretty easy and inexpensive.

I was pretty satisfied with the stock power. The reasons I'm going to E85 are that it's easy to find in the midwest, I don't have to worry about the transmission anymore, and since I'm already having a tune done because of the swap I might as well have it tuned for E85 instead of paying for another tune later.
