short of a turbo or supercharger... i doubt it seriously, its prettymuch a lost cause, i would swap an SI 1.6 engine and SI tranny in there ASAP then you can actually have some fun, mini-me if you want, turbo/supercharger is more applicable, and integra computers help with the fuel and timing maping. other than that, maybie getting a new cam.. you can make it a mini-me by swapping a ( gsr?) head SOHC VTEC head onto the D15 block. then all you have to do is wire up the vtec somehow and your good to go, there pretty fast making about 120 or 130 horsepower depending on how its built and such.
