Fall 2020: Kits Currently Available! Selling to Shops and Individuals! Please email or use the contact page to order. 


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 Land Rover A/C compressor, alternator, and power steering pump, and fuel pump are retained. 


This setup retains the factory Land Rover radiator and a clutch fan, which eliminates the need for expensive electric fans and controllers. Exhaust manifolds are not provided in the kit, but aftermarket LS manifolds 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 exhaust pipe, which usually can be completed by your local exhaust shop. Email for more information.
