Hi Dean, welcome to the Forum. :thumb:

Regardless of anything else, you WILL need to either change the ECU or get it re-coded for the different engine! :ooh:

Modern ECU's are very 'engine specific', in some cases even 'Injector specific', & if ANYTHING changes that means the ECU doesn't have the specific coding for it, it's not gonna let the engine run! :o

So if your vehicle runs an engine with an ECU and you want to change it to a different engine, it's often a good idea to get the ECU that the donor engine came with as well as any necessary wiring harness! If you don't, you might just be headed for a truck-load of fun & $$ :eek:

Good Luck!

Apart from ECU and electrical issues take a look at the power bands of both engines especially if you tow any heavy trailer or caravan. The newer 5 cylinder Ranger has a long power curve compared to other models (and makes) so it depends on the problems you will find on the way. Engine swaps aint what they used to be. Electronics will be your biggest headache so find a mech shop that specialises in these things especially a customising restorer or an auto sparkie who is up to the mark.
