Jumper harness can be got from many places on line as well as from us if you need one. The engine will drop right in. You will need the itr intake elbow as the throttle body is a little bigger. You will also need to use your ek9 shafts if its from a 98 spec as the itr shafts are bigger on that model. Other than that is a plug and play install. Can be done in a day if you dont run into any seized bolts. With our climate though thats never going to happen so would say 2 days to be safe.
