for a lightly modded vr4 i would reccomend 550s for e85 use. maybe even a 13g car but might need a slight pressure bump up top.
550s and a fuel computer. 450s without a fuel computer (the ecu should be able to tune enough for them on e85)
i would still reccomend an afc on both so you can go back to gas if necissary.
