Hey guys was wondering if anyone knows if i was to replace a 3.5 injected motor out of a 87 range with a 3.9 from a 94 disco, will the motor ecu just plug straight in or is the pin/wire configuration different ?

which ecu do you want to use ? the later disco one will be wired differently, you should use the complete 3.9 loom and ecu.

or keep the 3.5.
honestly to date I still think my 3.5s were better than any of my 3.9s.

With the early model injectors thou will it run lean on the 3.9 ?

I think they should flow enough for a 3.9.
