Never heard of Rover using the Jtd diesels from fiat?
A couple of prototype "g series" cars made it onto the road, I have seen only one in a running car. That was the l series with common rail injection and a VNT turbo. Like hens teeth thtough.
Converting a normal l series to common rail would be a mammoth task and require and ecu, loom and all the sensors from another vehicle. It's not like us diesel guys can just buy a "universal" aftermarket ecu to control such projects.
Realistically to get better attomisation it is a case of experimenting with different nozzles and break pressures and just hope the pump can cope.
The other big limitation is that timing advance cannot be altered in the main ecu, it has to be done via the ecu on the pump itself which nobody I know of can access.
