if you want to make it fast with the sohc motor it is totally possible - decide if you want to spend the money on a motor swap or turbo setup - motor swaps can cost a lot but have great results - if you stay sohc and want a turbo down the road, look at an exhaust with a big diameter (Apex or custom(2 1/2 to 3") - if you are swapping motors, go for a Spoon or a Mugen exhaust
