Whats jdm mean in terms of acura integras ?

so ive been reading and learned the difference between the engines and how they call it, i personally just bought a dc4, but wtf does jdm mean ?Whats jdm mean in terms of acura integras ?
it means the engine is from Japan. cars in japan undergo rigorous tests for safety and smog when they are 3-5 years old (i dont remember the actual time line). and it is often cheaper for the car owner to just buy a new car than to keep their old one, so many of these engines/transmissions/anything-else-it-i鈥?will get shipped to us here in the stated to replace damaged or worn out parts with ones from japan with generally 30k-50k miles one them. it is not a bad thing really, most of these engines are just starting to be broken in and will be good for years to come. the thing to watc out for is if you are in a state that follows CARB regulations (Cali for example) most of the engine configurations not orriginally available for sale on a california car are not CARB approved and therefor will not pass smog making them not roadworthy in the eyes of the state not matter if they are cleaner or safer.
japanese domestic motorsWhats jdm mean in terms of acura integras ?
JDM is Japanese Domestic Market, which is the engines and parts made for the cars that do not leave Japan. The Japanese domestic laws require cars to be recycled a lot sooner than those here in the USA, so there is a fairly large supply of serviceable used engines for Japanese cars that have found their way to the US
why do people say japanese domestic motors??
