what they are doing. As soon as your car gets in a bay, they should be able to have the engine out and back in and have the car running and any little issues ironed out in LESS than a weeks time. When we did my engine swap, we had the engine out in 1 day, and it took us another day to drop the JDM back in.
Thats assuming that they JUST pull the engine and turn around and put it back in. What are you wanting the engine pulled for?
