Currently Beta Testing! Contact us to be part of our Beta Test Program for D1. Introducing the Land Rover Discovery 1 LS Swap Basic Kit. This kit allows you to couple a GM LS Gen 3 or Gen 4 engine to your Discovery 1 using the factory ZF 4HP22 transmission. This solution is a lot less expensive than changing out your engine and transmission together. Since everything stays in the factory position, there is no need to rework your driveshafts or engine mounts. Because the Discovery 1 is more simple electrically than the Discovery 2, this swap is more straightfoward.
The kit includes:
- Bellhousing Adapter
- Installation Instructions
Since this kit is basic, we only provide installation instructions for the installation of the bellhousing. The rest of the setup is for the end-user to decide. Because the 4HP22 requires a kickdown cable, we recommend LS engines supporting the drive-by-cable ECMs. However, other configurations could be used. Additionally, we recommend fitting GM accessory components, rather than reusing the factory GEMS accessory drive. This kit has not been tested for all configurations of the Discovery 1, only for functionality with the 4HP22.
We recommend using the 4.8L LS engines with the Discovery 1 4HP22 transmission with the mechanical valve body at this time. This provides a significant power bump over the 3.9 and 4.0 Rover V8 engines, and even a bit more than a retrofitted 4.6. Larger displacement LS engines, like the 5.3, can be used, but it is recommended to upgrade the internals of the 4HP22 to 4HP24 specifications. Alternatively, the electrically-controlled 4HP22/24 from the Discovery 2 can also be fitted with additional components. See our page on engine options.
