What is a remanufactured car engine?October 21, 2026
What is engine assembly?T30 is the chassis code for Nissan’s first-generation X-Trail (2000–2007), not an engine code. The T30 models were primarily equipped with the QR20DE (2.0L) and QR25DE (2.5L) gasoline engines.
The QR20DE and QR25DE belong to Nissan’s QR series of inline-four engines, introduced around 2000 as successors to the SR series. They feature an all-aluminum block and an aluminum
DOHC 16-valve cylinder head, with chain-driven timing and CVTC (Continuously Variable Valve Timing) on the intake side. Known for their compact design, fuel efficiency,
and everyday durability, these engines served as the primary power units for the first-generation X-Trail (T30).
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
