now the question is... can the stock fuel system deliver enough fuel to run e85. if so, we are in for interesting times.
thats how i tuned by WRX, uses cobb access port and access tuner race, i run e85 or 93 oct gas. with e85, i get 300whp on a conservative tune running a slightly bigger bolt on turbo, cobb turbo back, slightly bigger top mount. all of the work done buy me. since the turbo, turbo back and top mount were all simple bolt ons, it was pretty easy to do and provides a significant power increase on a stock, unmodified motor.
