It's not that bad to do this. Both an 01 2.7 and the 2.5 utilize the earlier return-type fuel system, and both use the same injectors. The 2.7 does have VarioRam, so you'll need to run the additional wire to the DME to control the flapper. As the 2.7 is E-Gas, you'd need a cable throttle from an early 3.4.

You COULD just swap the 2.5 manifold and throttle onto the 2.7 and it'd run fine- the added .2 liter of displacement isn't going to be a big deal for the DME to figure out, but if it were me I'd make the 2.7 work properly in the car, as it's not that much more work to do so.
