Anythings possible with enough money and skill.

BUT, taking a V-8 out of your limited for that hunk of **** 3.7 would be extremely stupid. You're going to lose serious power, and more than likely not gain any fuel mileage.

I might be taking a shot in the dark here...but you even asking this question means that you probably don't have the know how to do the job.

If I'm wrong, I apologize.

This would probably be more work than it is worth. What is your aim with this project?

The 3.7 hasn't quite proven itself as the 4.0 and 4.7 have, but it seems like it might.

Well thanks alot for the posts "Firefight" the whole purpose of this is to get my 2000 grand jeep cherokee up and running, it's been into an accident and the frame is in prime condition, however needs body work new radiator and doesn not start (Battery most likely dead), as well as i had a cylinder down before the accident, poor baby has been in a rough battle till 2004, My plans with this are to A rebuild the bosy (Done), B rebuild/replace the engine.

Now i was thinking about getting a new engine block and rebuilding the one i have now since it hasn't been moved since 2004 and been outside with no protection, was thinking of doing a port polish on my V6 4.0l I6 Engine (do not have the V8), and in the meantime driving it with the Dodge Nitro 3.7L Engine (since it set me back on 500 CAD).

And Yes Firefight, I do not have the complete know how, however i am in my 2nd year in the Automotive industry and am able and willing to bust my balls to get my jeep back on the road. I have a Mechanic friend who is willing to help me on the weekends and this process is going to take me several of months, we have the tools but time is the main challenege.

Any suggestions on how to avoid the engine swap process?, or should i go ahead so i can have access to a car while we repolish rebuild and test the V6 engine???

Thank you all

You should have no problem finding a donor WJ to pull another 4.0 from...

x2 on the WJ donor! It's gonna be way less custom work, why not spend the extra time it'll take you to swap in the 3.7, and do some work on a 4.0?

I'm confused: you say you want to rebuild the existing engine, but yet you want to put in a completely different engine setup while you rebuild so you can drive it?


Do you have another ride? If so, pull the darn engine and rebuild it already. Save up the money you'll spend on the 3.7L (not to mention the other parts that you'll need to swap over! Little parts like: transmission, cooling parts, motor mounts, ecu, etc, etc...) and put it into the rebuild.

If you're gonna rebuild it, do it right.

If you're gonna swap it, just get a V-8 and be done with it!



(that said, if you're going to swap in a V-8, you'll be money ahead to just buy a Jeep with a V-8 already in it...)

3.7L - V6.

4.0 - I6.

The 3.7 is basically a 4.7 with two less cylinders. If you're gonna swap that, you might as well swap in a V8.

Just find another 4.0 to swap in. It is not worth the effort to make everything happen to put a 3.7 v6 in there. It would be a complete waste of money to fab everything to get it in there, especially if you are taking it back out. You cant just throw in a engine that never was in there before. I wish that were the case, but its not that simply, especially these days with all the computer controls.

Time is not the main challenge. The main challenge will be putting an engine in a vehicle that it doesn't belong. You can't just swap the engine...you're going to need a trans, drive shafts, etc...not to mention you'll need to rewire the whole thing. This is not easy task, and a complete waste of time and money. You're not gaining anything from it either, which is the worst part. If you even have the time, know how, and money to do this swap, I'd look to spend atleast 3-4k before its all said and done. You could have a helluva nice 4.6L stroker I6 for that kind of coin.

I'm scared, you say you're in your second year of the auto industry, but you don't know the difference between a V6 and an I6??

If at first you don't succeed, use more speed.

Lets not be a **** to the guy. People make the mistake all the time. Im sure you have to.

For the swap I would not recommend it but it would be a learning curve and who all can say that they have done that before. lol

Now that would be worth the work.......


slap another 4.0 in there and call it a day. Even if the motor costs more, it will still be a lot cheaper in the long run.
