What are the valve clearances on a Honda D15B?
The valve clearances for D15B were 0.2 mm for intake valves, and 0.25 mm for exhaust valves. Electronic injection system was mainly used in these engines, but the first versions used carburetors. Honda D15 firing order was 1-3-4-2. The size of D15B throttle body was 56 mm. The size of D15B fuel injectors was 240 cc.
What kind of engine does a Honda D15B have?
There are three cylinder head types depended on modification: 8 valve, 12 valve, and 16 valve heads. The most common engine is the D15B with 16 valve cylinder head. Also, the engine can be SOHC or DOHC and might include VTEC variable valve timing system. The engine has a timing belt.
What’s the compression ratio on a JDM D15B?
D15B VTEC was an enhanced JDM D15B, here 137 mm long connecting rods and 27.4 mm high pistons were used, which increased the Rod/Stroke ratio up to 1.62. Besides, a VTEC system was added, the compression ratio was increased up to 9.3, and the engine power reached 130 HP @ 6,800 rpm, and the torque was 138 Nm @ 5,200 rpm.
What’s the compression ratio on a Honda D15B?
D15Z1 was an analog to JDM D15B VTEC, but with an improved head; it uses the VTEC-E system, 27.75 mm high pistons, and a new ECU. The compression ratio was 9.3, the power was 92 HP @ 5,500 rpm, and torque was 132 Nm @ 3,000 rpm. 15. D15Z3 replaced D15Z1, and features a slightly modified VTEC system and a new ECU. 16.

How to remove and replace valves in a cylinder head?
You need to remove the schrader valve first before you attempt this, if not, air will not flow into the cylinder. You can also use a piece of rope or equivalent to keep the valves from dropping into the cylinder while you work. This method works well if you’re just replacing the valve seals.
What kind of power does a Honda D15B2 have?
D15B2 was an analogue to D15B1, but with a different camshaft, with an improved exhaust manifold and another ECU. The power was 92 HP @ 6,000 rpm, and the torque was 119 Nm @ 4,700 rpm.
How often do you change timing belt on Honda D15?
The cylinder block was covered with a non-VTEC SOHC head with 3 valves per cylinder. Later, versions with 8 valve head and 16 valve head were produced. Some models had the VTEC system. This information can be found below. For D15, a timing belt was used to be replaced after every 60,000 miles of mileage.
