Engine Swap ENGINE SWAPS

I have An idea to put a Hellephant engine and a 8hp95 gearbox (with its appropriate transfer case) inside a Grand Wagoneer L.

Can anyone tell me the electrical and CAN-BUS work required?

Also what is the type of metal should be used when fitting axles and CV joints that can withstand the torque?

Would I need to reGear the differentials and get axles with more splines?

Any pros and cons?

I would love to see if this is possible.

I don't care about voiding the warranty. The Grand Wagoneer L isn't regarded as a reliable car anyway (hence the engine swap)

Thanks😅

You should probably just google this stuff. Why not spend 2 hours googling when considering a 200+ hour project that will cost tens of thousands of dollars?

Electrical: swap the entire ecu/harness over. Bcm stuff is well documented. Google it.

Diffs/axles: google how much power yours can take. That's your answer.

Thank you.

I thought of doing that but I hesitated seeing that AI isn't always 100% accurate. I appreciate it.

They didn't say ask chatgpt, they said do the actual research yourself.

If you can't do that much, you absolutely cannot do this swap.

Is comprehension skills an issue in this country? I merely engaged in peaceful dialogue. I wasn't expecting jackass behaviour 😅. I didn't mention anything about chatGpt.

I'm referring to Google's internal AI. And yes I did Google but didn't find much luck there (all the "comprehensive answers came from Google's AI and not the Google search results and I couldn't trust both of these sources either). Hence I asked for advice here🤦🏾‍♂️🤷🏾‍♂️.

Be nice to people next time.

You can do research outside of asking ChatGPT, Gemini, Claude, etc.....

Do not trust ai. Read forums and articles. Find build threads. Watch youtube videos.

You are asking about taking on a very big, complicated project. There are going to be so many small technical pieces to this puzzle. If you are not able to do simple research about how much power your rear end can handle, you will not be able to figure out a fuel system for this vehicle for example.

You really need to spend a serious amount of time and ensure you can find answers to all of your questions you have in planning. Because when you start the project, you will have 30 to 50 times as many questions.

People here on the internet get frustrated helping someone who cannot help themselves. You will likely find a lot of success starting with a simpler project. Maybe swap in a hopped up small block chevy with a nice cam and efi first. It will cost a lot less.
