Is that 100 octane fuel leaded by chance? If yes your cats won’t last long.I already have 1000cc’s. Got a good deal on them, $250. I have better access to 100 octane than E85. The pump is on my way to work. I only drive the car once or twice a week. It’ll probably cost me another $2,500 for the bigger injectors & flex fuel kit. I don’t mind buying bigger injectors, if I have to, but would prefer to spend the money elsewhere.
