Buying a new unit,[secondhand-but in the box], going into a EF auto. Will the transmission handle this, will the battery have to be moved and where, will the injectors and ecu have to be changed or chipped?

sorry dude but prepare for a flaming cause this has been answered a million times before. Try the search function and search for EF and Turbo cause i know there are heaps of threads about this.

Thanks
