How hard is an R380 M57 swap?

A M57D30 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: R380 gearbox adapter kits for an M57 Defender conversion.

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.
