The standard kit to convert a Discovery 2 to an LS Engine. This maintains the functionality of all dash guages, the check engine light, as well as traction control and hill descent control. The factory Discovery 2 A/C compressor, alternator, and power steering pump are retained using our accessory brackets. This kit allows the LS to work with the factory Land Rover ZF 4HP22 or 4HP24 transmissions found in the Discovery 2.


This setup also retains the factory Land Rover radiator and a clutch fan, which eliminates the need for expensive electric fans and controllers. It also retains the use of the factory Discovery fuel pump. Exhaust manifolds and an oil pan are not provided in the kit, but aftermarket LS manifolds and oil pans are recommended in the parts list. The kit is designed to be bolt-in except for the exhaust. The only welding that is required is to connect the exhaust manifolds to the Land Rover Discovery exhaust pipe, which usually can be completed by your local exhaust shop.
