anyone know how to make e85 conversion kit?
 

pretty much what the tittle says. Does anyone know how to make an e85 flex fuel kit? or know where to get the info? I see the kits out there, but I done want to spend 400-500 dollars to get one. I'm mentioning the kits that have a circuit board inside a box then you plug into your injectors, and have a hot and ground wire. I don't mind building one, but I don't know how to do it. can I use an adjusable fuel pressure regulater to run e85?
