Depends how much HP you are envisioning. If it's more that 10 or 15, the only way I see that happening is a turbo...which you really can't do on a high mileage engine
I'd go for better handling - tires, shocks/struts, maybe springs. You'll feel the improvement at every corner. And make sure the engine's in top tune - plugs, wires, etc.
