You can go the expensive route and do the K24 conversion which will change the engine bay drastically or you can go the old school way and drop a B20 block with a VTEC head and/or turbo and nitrous. Imagine a grocery getter with a tree stump pulling engine that can run 9,000 RPM and still get decent mileage. Then again the K blocks do all of what the B's couldn't handle. High Air to Fuel ratio, better block rigidity, and astronomical power to wieght ratios.
