What do you want to do power wise in the future? If you have a 14/14a ecu and loom you can go to a hdev or similar generic chip/map but if you get a 15 ecu you will have to run power fc/standalone.
Diff ratio will probably be different so your speedo will be out depending on the box you get, also the pick up for the abs/speedo might not be the same (if you have abs?)
Are the non turbo brakes up to the job, smaller than the 4 pots on turbo cars?
As mentioned prop and ignition amps are different between models.
Good luck with it!
