SausageMahoney Posted August 6, 2005 Share Posted August 6, 2005 I believe the only difference is that the 03' had a MAP sensor, and the 99' used a MAF. I have access to a wrecked 03' with low milage, and my RS has almost 120k on it. I think the Legacy also has a rear L.S.D., it would be nice if that fit. If anyone knows anything about this, please don't hesitate to post. Link to comment Share on other sites More sharing options...
Legacy777 Posted August 7, 2005 Share Posted August 7, 2005 I thought all the newer legacies had MAF sensors...... Is there anything wrong with your current motor? 120k on a subaru is peanuts. You could swap the motors. I'd recommend using your current intake manifold and wiring harness. Only issue I can see is if the shape of the port on the heads for the intake is different. That would keep you from using your current intake manifold. Link to comment Share on other sites More sharing options...
