I drive my car for a living, the D15Z1 is a great economy engine, but it's time for me to swap a little mpg for hp as I find myself often running out of road while trying to pass. This is a jdm D15B vtec-e, it runs best on 93 octane, not sure why - higher jdm compression??, but it will detonate a little if you pull long hills and run 87. Around town or flat lands are not an issue on 87. I live in the mountains and have been running 93 to prevent engine wear.
I purchased this engine from Hmotorsonline so it was suppose to have approx 40k miles. I've put 63k on it since last year, which has been nearly all hwy miles. Here's the scoop - All new hoses, both new vtec solenoid gaskets, new t-stat, timing belt, water pump, ignition coil, and valves adjusted at 63k ago. The engine is healthy, does not smoke or use any oil, purrs like a kitten and does not have that typical worn out D series diesel sound. Compression checked 180 psi +/- 2 psi at 4 pumps on every cylinder the other day. O2 sensor is getting a little weak, but still knocks off 56 mpg when I try to maintain leanburn as much as possible. I run Rotella synthetic and change regularly.
Engine harness is included, intake tube, EGR box, and ECU (Federal). Flywheel is not included, but I do have a D15B7 flywheel if needed.
The engine is currently in service. $850
Also have a spare D15Z1 long block (no distributor, flywheel, oil heater or lower exhaust manifold) approx 125k miles $350
Also have spare intake manifold, exhaust manifolds throttle body, and other VX related parts, will throw for a little extra $
