If you have replaced the engine with another Phase 1 engine, ie same turbo, same injectors, same phase, then you shouldnt have any real issues unless the engine was screwed, phase 1.5's are slightly different but should be compatable as long as you have the same turbo etc, phase 2's wont be a direct swap as they have bigger injectors etc which means you will need a mapped ecu to run them correctly.
