How hard is an M54 E30 swap?

A M54B30 swap into the BMW E30 325i, BMW E30 320i and BMW E30 Touring 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: M54 3.0 kits for the E30, with mounts, sump clearance and loom.

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.
