Yeah, I've got a CRX with a D16Z6 with the 1.6 litre v-tec in it. It's a SOHC.
If you're really looking for power and torque, I suggest looking at the K series engines. They're a little bit more expensive, but they are slowly becoming more common. 2.0 litres, 200 horsepower, approximately. If you want more details just PM me or visit
www.k20a.org Those forums are full of stuff, and they have plenty of info for CRX swaps.
