I've got a 98 Civic hatchback with a D16Y7 motor. I'm a poor college student but would like to work on the motor but can't afford a DOHC and the engine i do have has very low miles on it. Boosting is out of the question since i don't have that amount of money. I was wondering on the potential of the D16 and what it's capabilities are. I was also wondering if the D16Z6 head can be switched with the Y7 or would i be better off with a Y8 head.
