As to your question: the only one I know of for G8 is the Sci Fi Anime Bodysuit; you can find it with a quick search here.
The only other plugsuits I know of are materials for the old V4 bodysuit, and I'm pretty sure the downloads are well and truly lost to time at this point.
There are a few nice ones from a guy named freelancecomics, but the links are long dead like ArgosyDreamer said. I'm considering just making my own anyway, you guys'll hear first.
