How hard is an N57 Defender swap?
A N57D30 swap into the Defender 90, Defender 110 and Defender 130 is a big job, but a good workshop can do it with a complete kit. Most of the time goes into the mounts, the adapter and the wiring.
The usual steps are: remove the old engine, fit the new mounts and the adapter plate, set the engine in, connect the wiring and the engine computer, then fit the cooling and the exhaust. A test drive and a final check follow.
Our kits come with parts that are made to work together, which saves time and guesswork. What we list: BMW N57 single-turbo and twin-turbo kits for later Defenders.
Before you start, check your local rules for registration and road tests after an engine change. We supply invoices and documents that help with this.
