Hello everyone, Jason here from Alabama. I've been an observer of this forum for a while and have appreciated all the info!
So, my crisis is that our 2014 LX is in shop currently needing engine replacement. One quote, from dealership was $22k and the shop it currently is at is $15k "ish", so not firm at all!
Our business has gone to hell and we are in an impossible financial situation that makes outlaying that amount of money a non starter.
We do have 2004 GX with the 4.7, 210k miles and runs! Can that engine be installed in the 2014 LX? If so, think pricing would be lower?
I appreciate any help you guys can offer!
Be good!
 
Anything is possible, you can put a tank engine in a Miata. But it will certainly not be cost efficient. Try finding a used 5.7.

I seem to have left something out. I am a car owner not a mechanic. Too large to comfortably fit in a Miata and I would image that putting a tank engine into a Miata would be something that actually is impossible, unless of course, you turn the Miata into something other than a Miata to receive such an engine.
Also, if you had any idea of how to offer help you would have probably read two important pieces of information, $22K and $15K. Now, I am not someone who reads forums in an attempt to expose my pompousness, but if I was so inclined, I would have probably determined that the $15K cost probably involved a used, rebuilt engine and the $22K, dealer engine was a factory rebuild at the very least. I however would have been wrong, because both engine quotes are used.
So, do you feel as if installing the 4.7, which I already own, would be more expensive than the two quotes I have received? Maybe so, that is my question.
 
Putting the 4.7 in will involve a lot more than simply physically fitting it in the engine bay. I don't know if the engine would mount to the 6 speed in your LX without an adapter. You could swap the entire drivetrain (engine, transmission, transfer case, ecu, tcu...) but you'd still have to deal with all of the electronics plus misc. physical parts such as driveshafts, shifter linkages, etc. You'd basically strip your LX and and 470 and then try to merge them. It's possible but I would not want to go down this road unless it was purely a hobby car type of situation that you enjoy working on. And likely only a very few, select shops would want to take this on.

Your best bet is a used engine, but there are multiple threads on this forum about how hard it can be to find a good used engine. $22k though seems very steep for a used engine, even including labor.

Sorry that this is not likely what you want to hear.

Thank you Moby! Just wanted to get some input from folks that know. Kinda tough not having a lot of experience with this and feeling confident I am not getting lead in the wrong direction.
I appreciate your input, take care!
 
What happened to the original engine? Did a valve drop on it?

If looking for a cheaper option, some people have had success using a used 5.7 Tundra/Sequoia engine and swapping some of the ancillary components from the old engine (such as the oil pan) since not all of the bolt on parts are the same between the Tundra and LC 200, but the block itself is the same.

I’m not sure if the shop you are using would be willing to bite at that, but it’s worth a shot.
 
Used engines are around $5k, and installation pricing should be around $5k max. Find another shop.
There is at least one thread where a used engine was purchased and installed for around $10k.

technically...and federally you cant put an older engine in a new vehicle. so if you have emissions bs to deal with youre going to have legal issues putting a 4.7L in a 5.7L vehicle.
 
I would ditch the LX and find a cheap beater before swapping a 4.7 into a 200 (assuming it's even possible to do?). The electronics of both platforms are very different. You'd be turning your running GX into a parts shell and your LX is now worthless in terms of resale. Just a bad move all around, again, assuming you could even get it running, which I think is highly doubtful. $15k can get you a good reliable vehicle.

Why not just drive the GX until your finances improve?
 
As others have stated, a used engine can be had for ~$4k-$8k. Check www.car-part.com to find available engines in your area (or find a lower mileage one further away and ship it).

The 5.7 3URFE engine swap is no simple job ( I think the 4.7 2UZFE swap is probably not practical). I think it would take me about 60 hours to complete, but I must state that I have yet to do one on the 200 series. I think $15k is not unreasonable for a mechanic to charge, given the time and used engine cost. Definitely worth shopping around and finding a competent shop if you can't tackle this yourself.

I would favor a low mileage used engine over a rebuild, unless you are confident in the rebuilder.

Other options... use the GX and sell the LX as is ... swap the engine and then sell one or the other... possibly repair the existing engine? Did it overheat? Drop a valve? Details could reveal a cheaper path forward.

I’ll take the blunt approach to answering the question and simply say you can’t put an ‘04 GX 4.7 into a ‘14 LX. But first, why does the ‘14 need an engine? Is it completely destroyed? Need a new head? Need new head gaskets? If you’re sure it needs a new engine and you can’t afford it, you might consider selling the LX as is and putting the money into an inexpensive used vehicle you can use for a while. The used market is crazy right now, but you should be able to find one you can afford with the LX money, assuming the LX is in nice condition other than the engine.

I answered your question with an exgaggerated example of Miata. From it, you could determine that swapping the 2UZ into 200 series chassis is likely not a $15k cost. An engine is of course only part of the cost equation when swapping into a completely different vehicle. You'll have the transmission, harness, likely driveshafts, electronics, etc etc to deal with. So you're welcome for the help, Jason.
