Firstly, you could look into stroking the engine to 2L's. However, if your going to buy an evo in a year, my advice would be to stop pouring money into your sportivo and put up with it for a year, chances are you wont get your money back from the mods you spend now. Then again you could look at buying something else now and put off purchasing an evo for another few years. Why not a earlier model evo 6,7,8 or S15 200sx?
