Hi and welcome back.
First, I'm sorry to hear you are still having trouble. As far as installing a different type of engine, it is a total headache. Can it be done? Yes, it can, but be prepared. Mounts need to be modified which will likely include welding, the wiring harness will need to be replaced, and the donor vehicle PCM and TCM, if it has a TCM, will need to be installed into your vehicle. The engine vacuum hoses will need to be rerouted and changed. The fuel lines will need to be rerouted. The exhaust won't align. The list goes on and on.
You sound like too nice of a person. LOL, I wouldn't want to tell you it's easy. It is truly a nightmare to do and usually, there are one or two things' people can never get to work properly. Usually, it is emissions related and won't pass.
It would be easier to completely rebuild your engine. Actually, it would be less expensive to get a good OEM engine specific to your vehicle.
I'm here to help in any way I can, but this will really be a tough one to do online.
Let me know if that makes sense or if you have other questions. We need to get it running again, but this is one way I personally wouldn't recommend.
Take care,
Joe
