    I don't know for sure but running 87 in a boosted motor will most likely transform it into a blasted motor.. And no problem running ethanol in anything as long as it's tuned accordingly.....

    Give the motor what it wants...both in octane and tune.

    The E15 won't store the same so do your homework on that part also.

    Well, that is very little info. And 2 poor choices. (not on your part, thank the govt) How much compression? Blown boosted? Turbo? Intercooler? RPM range? etc.
