It all comes down to personal taste.I got lucky swapping and got a good motor,as did many and sure you can build up a sohc,but really it's gonna cost pretty close to what a swap would(after you include turbo) and from what I've seen the majority of people can't tear down a motor and rebuild it as fast as they could just pull a motor.So to everyone thinking about getting more power,SOHC or DOHC, think about what you need your car for as opposed to what would be nice next time some dork revs on ya.
