I have changed my D15B2 to a JDM D15B and let me tell you that when someone tells you to change your timing belt before installation, DO IT!!! I finally figured out what was wrong with my engine (bad coil in the dizzy), and it fired up for a brief second and stalled when I hit the gas. Then while cranking the engine over the old timing belt just broke into 4 pieces. It was old and dry rotted so it was time. But I'm assuming I get a timing belt from a Civic VX? D15Z1 right?
