How hard is a Cummins 6BT swap?

A 6BT swap into the Land Cruiser 80 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: Cummins 6BT 5.9 kits for Land Cruiser 80 and Defender 130.

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.
