JDM Alliance LLC will not accept returns or refund payment for items that do not fit. A return, exchange, or refund will only be considered if JDM Alliance LLC is found to have mistakenly posted incorrect information about the Japanese specifications. Please read the disclaimers below for full details.
Shipping and transportation charges are non-refundable. Please take this into consideration before purchasing. We have no control over how far away you are or where an item is shipped, so we cannot assume the cost of returning it.

The engine block, cylinder walls, and cylinder head are also warranted to be free of cracks or distortion.
JDM Alliance LLC reserves the right, at its own discretion and determination, to repair with rebuilt or serviceable used parts, or to exchange the engine.
All external parts attached to the engine, e.g. VVTi systems, VTEC, intake and exhaust manifolds, carburetors, distributor, starter, emission control devices, flywheel, clutch and pressure plate, water pump, thermostat, belts, hoses, oil pan, valve cover, sensors, electronic parts (distributor, wires, computers, injectors, etc.), transmissions, drive shafts, engine mounts, half shafts, etc.
Limitation of Duration. Repairs or exchanges will not extend this limited warranty beyond the term described in the Coverage Periods above.
Disclaimer 1. This limited warranty is in lieu of any and all other expressed warranties of JDM Alliance LLC. Any implied warranty is limited to the duration of this limited warranty. JDM Alliance LLC does not assume, or authorize any person to assume on its behalf, any other obligation or liability.
Disclaimer 2. JDM Alliance LLC will not be responsible for incidental or consequential damages arising from loss of use, loss of time, inconvenience, commercial loss, or any other consequential damage or loss.
Engines complete with accessories may not comply with the emission-control laws of the state in which they are sold or used. State and/or federal authorities require that you change over the emission devices from your old engine to the engine you are installing to make it comply. The add-on parts on the engine are left attached for testing purposes only, for your convenience, and free of charge. The purchase price represents the cost of the long block only (i.e. the cylinder head and short block).
These are used engines that have been in service for approximately 20,000—60,000 miles (depending on the year of manufacture) and are not brand new. There may be small scratches because the engine is used. There may also be fragile plastic, metal, or rubber parts that could bend or break during shipping; these can be replaced with parts from your original engine or purchased from a local used auto-parts store.
By purchasing from JDM Alliance LLC, you acknowledge that you have read, understood, and agreed to the warranty, returns, and sales policy stated above.
