What is a JDM engine?

JDM stands for Japanese Domestic Market. These are engines and transmissions originally fitted to vehicles sold in Japan, where strict inspection rules mean vehicles are retired early and their drivetrains usually have low mileage.

How many miles do your engines have?

Most used JDM engines have approximately 45,000 to 65,000 miles. Mileage is approximate and comes from Japanese documentation. Each listing states the mileage range or notes if a unit is brand new or remanufactured with 0 miles.

Are the engines tested?

Yes. Units are inspected before they are listed. Review the specifications, condition and included components on each listing.

What comes with the engine?

Included items vary by listing. External parts such as manifolds, alternators, sensors and plastic covers may be included, missing or damaged in transit; the warranty covers the head and block internals only.

Fitment

How do I know if an engine fits my car?

Compatibility depends on more than the model year: engine code, transmission type and vehicle details all matter. Share your year, make, model, VIN and the engine code or transmission type with us and we will help you check before you order. You are responsible for confirming fitment before purchase.

Will my JDM engine pass smog?

We cannot guarantee smog or emissions compliance. Check with your local authorities, and in California with the BAR referee program, before purchasing.

Ordering and Payment

Which payment methods do you accept?

Major credit and debit cards, Shop Pay, Apple Pay and Google Pay online, and cash or card for local pickup. See our Payment Policy.

Shipping

How much is shipping?

Engines and transmissions ship as palletized freight. Cost depends on the unit and destination and is calculated at checkout or quoted by our team. See our Shipping Policy.

How long does delivery take?

Orders are usually dispatched within 1 to 3 business days and freight transit in the continental United States is typically 3 to 7 business days.

What if my shipment arrives damaged?

Inspect the shipment before signing, note any damage on the delivery receipt, take photos and contact us within 24 hours so a carrier claim can be filed.

Warranty and Returns

What warranty do you offer?

Replacement engines and transmissions: 60 days on the head and block. Performance engines and transmissions (VTEC, turbo, supercharged): 30 days. Rotary units, electronics and accessories are sold as is. See the full Warranty Policy.

Do I need a mechanic to install it?

Yes. Installation by a certified mechanic is required, along with an oil system, timing and cooling system overhaul. Otherwise the warranty is void.

Can I return an engine?

All sales are final. Refused or returned orders are charged a 35% restocking fee plus all freight. Defective units are handled through the warranty claim procedure. See the Return & Refund Policy.
