Thanks for your reply on that . It has taken me a while to get the engine and I finally got to put it in last week. I had read your reply before starting it and everything you had mentioned was correct. The oilpan, dipstick, and pickup are different on the J but swapped easily. The fuel rail was also different between the two. The oil sender just replaced one of the turbo oil lines near the starter. It was a pretty time consuming swap but the car runs better than it ever has since I've owned it. It even feels like it has more power because the engine isn't worn out like the old one, even with the compression difference. I first made the mistake of not replacing the injector o-rings the first time. Not a mistake I'll ever make again
The only issue I'm having is cold starts. In the morning(about 30 degrees out) it has a lot of trouble starting up. I have to crank it for quite a while before it tries to fire and for the first couple minutes of driving it stumbles on acceleration from a stop. After that it clears up and runs perfect. I'm swapping the coolant temp sensor in the morning from my old engine to see if that might be an issue. The water pump failed on a test drive because of rust from sitting for a long time so I hope it's an issue with corrosion on it. I have a check engine light on and will be scanning it at the same time too.
