I assume you are looking for the Bosch part numbers for the CIS injection as used on the last of the G-Esprits? I was never able to find a cross reference and using the part number off the original components didn't work either. Some of the items are Lotus specific like the fuel distributor, rigid fuel lines, warm up regulator, etc., but I'm sure things like the injectors and fuel pump are common parts. If you ever find a cross reference, please post it.
