M52TU/M54/S54/S62 into E30/E36 Adapter Harness

Regular price $599.00

We produce these harnesses as a plug and play solution that allows you to use a newer motor in your E30/E36. These use all new OEM plugs (a few exceptions for NLA plugs and pins) and feature OBD2 connectivity for ease of troubleshooting. You will need to have a complete engine loom with O2 sensor and power sections of the loom to use our adapter.

These adapter harnesses are made to suit so we need to know your vehicle production date and the chassis that the motor came out of.

We are currently offering half price performance flash tunes to go with the swap adapters, this can be on your own DME you supply or we can also supply the DME ready to go.

Harnesses are made to order and we aim for a 3-4 week turnaround time but this can be longer depending on demand. If you would like to make an order, please send us an email describing your setup and we can give a tailored quote.
