Good day. I'm from the Philippines and I just got a 2006 Honda Civic with a K20Z3 engine and a 5-speed manual transmission. Does anyone know if this comes with a factory LSD? If no, is it possible to install one? Also, do Civics with R18 engines and 5-speed manual transmissions come equipped with an LSD too or is it just an open diff?

 

Your Civic should have a K20Z2 engine. The transmission is non LSD. You can install an LSD in it with no other modifications, message me to order one. The R18 is non LSD.
