Frequently Asked Questions
Common questions about Project JDM, JDM imports, and our tools.
What does JDM mean?
JDM stands for Japanese Domestic Market. It refers to vehicles and parts originally manufactured for sale in Japan. These cars often have different specs, features, and engines compared to their export counterparts.
How do I import a JDM car to the US?
Under the 25-year rule, you can import a vehicle that is at least 25 years old without needing to meet US DOT and EPA standards. For newer vehicles, you will need to work with a Registered Importer (RI) to bring the car into compliance. Check our import guides for step-by-step details.
Are the product recommendations on this site sponsored?
Some links on our site are affiliate links, meaning we may earn a small commission if you make a purchase. This does not affect our editorial independence — we only recommend products we genuinely believe in. All affiliate relationships are disclosed.
How do I use the comparison tools?
Our comparison pages let you see specifications, pricing, and pros/cons of similar JDM vehicles side by side. Visit the Compare section from the main menu, select a category, and pick the models you want to compare.
Can I suggest a vehicle for the wiki?
Absolutely! We are always expanding our wiki. Send us your suggestion via the Contact page and we will prioritize popular requests.
How accurate are the budget calculators?
Our calculators provide estimates based on typical market data and common modification costs. Actual prices vary by region, condition, and availability. Use them as a starting point for your research, not as a final quote.
Do you sell parts or vehicles directly?
No, we are an information and comparison resource. We link to trusted retailers and marketplaces where you can purchase parts and vehicles. We do not handle transactions directly.
How often is the content updated?
We regularly update our wiki entries, price data, and comparison pages. Blog articles are published on an ongoing schedule, and older content is refreshed when new information becomes available.
