I recently converted my car to use 100% e85. It has the stock turbo and IC, stock block and heads. It's not a track car, just street cruising. I went with the 60 lb injectors and chip from Turbotweak. Eric has said you can get to mid 11's on 60's and I'm not even close to that so it seems fine. I believe with 80 lb injectors you need more than a single pump so there is no point in doing 80's or larger unless you are doing a double pump setup which I didn't want to do as I just bought a Walbro 340 last year. 20 psi boost with no knock at all and it pulls hard!
