Where are you located? The ej20 turbo has dual variable valve control, it will require the ECU and immobilizer from the donor vehicle. This question has been answered many times, so try Google search legacy gt turbo swap etc. Most members will say it's not worth swapping to a turbo motor unless you run an aftermarket ecu. Its much cheaper to buy a legacy gt than to convert it to turbo. That is of course assuming you dont already have all the parts you need. If you did, then you wouldn't be asking. Anything is possible with time and money, decide if it's worth it to you.
