Stuffing a 5.2L V8 into a Jeep Wrangler - Project Introduction | V8 TJ Part 1

- Опубликовано: 29 сен 2024
- This is the first video in a project series where I show you what it took to install a Dodge 5.2L(318 c.i.) V8 into a Jeep Wrangler. The process would have been exactly the same for a 5.9L(360 c.i.) V8 as well.
I found scattered information across the internet and I hope to compile what information I did find and shed some light on the process of swapping a Magnum engine into a Jeep Wrangler for those who choose to follow in the same footsteps.
The biggest and best resource I came across during the swap was on a JeepForum thread: www.jeepforum.c...

Must be a sweet drive… I had both a 97 4.0L Grand Cherokee ZJ and a 96 5.2L Grand Cherokee ZJ and let me tell you… the difference in mpg was barely noticeable but in power and the driving experience was night and day… plus the V8 came from the factory with an engine oils cooler, transmission fluid cooler and way higher towing rating. Jeep should have made a V8 TJ. 😎
Nice job
Thanks!
Collecting parts for this very swap into a 1997 TJ with manual Ax-15
Manual is the best way to go with this swap IMO. Less wiring.
Do you need to get a manual 5.9 or 5.2 ECM/PCM or will auto or manual work?
@@zackarymccullough5368 You'll need a manual PCM for a manual transmission
Looking to buy a tj wrangler as well and do a hemiswap as well, but with a manual transmission instead, would it be about the same with a manual? I'd be looking for a 5.7 though. I dont really know jeeps or dodge so I'm new to all this
Everything is cool but the snow... soon you will have a cool extremely corroded Jeep... I can’t wait for the next videos.
Snow sucks! Thats why this Jeep sits in the garage November-April; it should never see road salt again.
So you didn’t change your axels at all? I’m looking to do same I’m ready to replace the under power 2.5 cyl
Yes, I put a Dana 44 in the rear and keep the Dana 30 up front. I'm currently running 3.73 gears on 33" tires and it seems like a good combination.
Dirona thanks man. my brother still have his Dana 44 so that’s awesome . Now I just need to find everything else
Hey great v8 swap! I'm in the process of a 5.2 swap too, the only thing that keeps me from doing it (besides corona) is the wiring harness part. Once your are done with the wiring for the engine, what do i have to do with the other electronic components? If i do an standalone wiring harness with working gauges, will i need another harness for things like parking lights interior and exterior lights blinkers etc or after the engine part done i have to add more wiring to the new engine pcm? I'm totally new with this i think i'm running in circles for nothing 😅😅😅 thanks in advance
No extra wiring needed, that’s the beauty of this swap! Splice the V8 engine connectors (and transmission connectors if you’re installing an auto) into the jeeps engine wiring harness, swap in the v8 pcm, and you’re done, no other wiring mods needed. Easier said than done, but probably one of the most simple modern engine swaps you’ll find. Just make sure your jeep and the donor pcm have the same interface style (CCD vs PCI)
You mentioned the original driver driving short trips with the jeep and not properly warming it up wouldnt be so good for the engine. Being that I do as well do that, how should I be warming it up?
Here's a quick explanation: community.cartalk.com/t/how-can-one-alleviate-bad-effects-of-frequent-short-trips/70855/4
Care to share what vac line you plugged into the port on the throttle body? On your engine it looked like it ran to the rear of the engine. I’m doing this swap and trying to figure out where the evap lines from the TJ go on the 5.2. Thanks.
I basically took all the vac line pieces from the TJ and from the donor vehicle and pieced them together as needed. No real rhyme or reason to it other than connecting them together as cleanly and organized as possible.
Then you should swap rearend to a 8.8
Went with a dana 44 on this one, but my other jeep has a 8.8
that does look very factory
Thanks man
right! very clean.
Working on a 5.9 swap myself this winter. Can't wait for more videos!
Hey man, fantastic video! I'm watching your whole serie, I'm looking into swapping my 2.5L 4Cyl for something bigger.
Obviously you're swap is legendary it's so clean and sounds very good. So I'm leaning towards doing the same thing.
I'm just slowed by the fact that mine is a YJ and you swap a TJ. Is it still okay, am I going to run into issues, also.... does it matter what year is my 5.2L that I will be shopping for?.
Thank you so much for all the videos.
I can’t give much info on swapping into a YJ, but more than likely your YJ is running an OBD1 diagnostic system, so at the least I’d probably try to find a donor with OBD1. OBD2 came into play around 1996. Beyond that I’d do some searching at jeepforum.com and see if there’s any info from others who have done the swap.
Just draged home a jeep tj and a dodge durango with a 5.2 , know I know what im doing this winter
Also the 5.2 I has burns a little oil on start ups but not while driving ?? Valve seals ? Any info helps
Cool project! That’s a possibility
Hi, I would like to do the same swap (5.2 and BA from ZJ to 2.5TJ) as you've done but at the moment some information are missing to me about the ECU. I need to know the VIN number for the programmation of the ECU that I need to buy it in US, can you please help me and provide this number if you know it? Or maybe if you can provide me some other information or contact about it, it will be really helpful. Thank you and good job about your car.
Unfortunately I don’t think I can help you with that. I would say your best bet it to use the ECU from the same vehicle that the engine came from. I’m not sure if the vin is programmed into these ECUs, I’ve attempted to read the vin from mine with a scanner but have not been able to.
I have a question what year and size engine is your ford explorer cooling fan off of?
I believe it would be a 93 explorer with 4.0 engine. Specifically I used Dorman part # 620-112. Was around $25 if memory serves correct
You can use a Jeep wj Electric fan with the 4.0 fan shroud
-13 Celcius isn't so cold, but the styrofoam sound of the snow begs to differ, the NE humidity makes it go right through the bone! Cheers mate, love the V8 swap!!!
Nice looking swap, looks very oem for sure. I take it your state doesn't frown on engine swaps?
Thanks! They don't seem to care what's under the hood as long as you can pass an emissions test and don't have a check engine light on the dash
360 bored out to a 408 stroker would be a beast
I've considered it, but I actually like the 5.2 as is. Wouldn't complain if it were a little better on gas though (but its not much worse than the 4 cylinder it replaced).
5.9 is externally balanced. You would need the flywheel rebalanced or a swap flywheel.
3.9 would be better for a jeep
Why? I’m happy with the 5.2
Just saw this. I was thinking you were swapping in the 5.2 Shelby GT350 VooDoo engine. 8,250 RPMs. Guess not.
Maybe next time... lol
Great job! I love putting different engines in vehicles that didn't have said engine in there especially, if it's some sort of v8.
I'm conceptualizing a build for this winter on a 2003 liberty. I love that you made it look like a factory install and the "practical" side of you thought about gas mileage. I'm mulling over the same points either using a durango/grand cherokee 4.7l, or 5l ford. The 4.7 is the same engine family as the present 3.7. However, 5l fords are tried and true. And, both being small v8s (hopefully) will net better gas mileage. The other reason for those 2 vs the 4.8l LS is the physical size. The ford is smaller all the way around. I haven't found exterior dimensions of the dodge 4.7 tho.
That sounds like a fun project. I don’t know a whole lot about either of those engines but I do recall hearing complaints about the 4.7 dripping valve seats
Hi. Nice building.
I have a 2006 Tj with a 2.4 with 6-speed manual that I plan to replace with a 5.2 automatic from a -97 cherokee. What do you think about such a swap? Or do you have something to recommend? I have to use original parts such as fuel injection and catalyst if I am to get that road legal here in Sweden.
The closer in year the two vehicles are, the easier of a time you will have with wiring the new engine. I’d look for an 06 Cherokee with a Hemi to use, if those were available in Sweden
Nice work but I’m old school and would rather have a carburetor and manual fuel pump no sensors no computer no problems,
I agree, but I wanted to keep this swap emissions legal, and that meant keeping the fuel injection
Hello I have a jeep 99 wrangler it also has the 5.2 motor that was swapped into it I need some help I was wondering if there’s anyway you could help me I have some ECU questions
I'm not expert but I can try. I'd recommend checking out the 'Wrangler Magnum V8 Discussion' thread over on jeepforum.com too
I apologize if this was already addressed, but being that it is a 2003, did you have to deal with inspections? I was under the impression that it had to be a pre-2000 model. Would love to know the legality of such swaps and whether I can use a newer Wrangler. Thanks.
Emissions inspection requirements are vastly different between states, I would recommend looking into whatever state agency is in charge of doing inspections on your state and give them a call
Nice! More videos
In my knowledge and experience all jeeps (doesn't matter model) get 11-17 MPG flat regardless of engine and transmission. Biggest factor is the driver and type of driving
I can attest to that
would like to see a 5.7 hemi swap into a TJ or XJ...
I think the reason we don't see more is the cost of entry. The 5.2/5.9 Magnums can be had for dirt cheap while the Hemis are typically a few grand
Junk
Those had 4:10 in them
The jeep originally came with 4.10s but during the engine swap I installed a set of 3.73 axles to upgrade the rear dana 35 to a 44.
i have a 5.2 in a 95 grand cherokee that i am planning on swaping into my 04 LJ. is this basicly the same as the durango 5.2? would i need the computer and harness from the grand cherokee?
You're going to have a major wiring headache on your hands. I presume the zj has OBD1 and the LJ has OBD2. Your LJ has a PCI style computer so you'd ideally want to find a donor vehicle with a OBD2 PCI computer (check out the hotwireauto link in the pinned post at the top of the page).
Any interference or clearance work on the drive shaft and trans housing? In some research it has been stated that the 46RE + the NP231 causes some issue with the front shaft and trans body. Did you run into any issues?
I haven't actually installed the front shaft yet but I have a skinny aftermarket shaft and it looks like it will be a VERY tight fit. I may have to shave a bit of the lip where the trans pan mates to the trans to give a little more clearance...we'll see.
What about mounts
Used the Advanced Adapters mounts for this swap
This is a great video and probably the cleanest "factory" build I've seen. My question is about engine placement. What mounts did you use? Most people use AA mounts but ignore their placement instructions, and scoot the engine back as far as they can to avoid having to adjust driveshafts and transmission mounts. Personally I think that's ludicrous, but yours looks like it's properly placed. Just wondering if they were AA mounts in the recommended position. Thanks!
Thanks. Yeah, they are the AA mount placed in their recommended position. Have plenty of access to the engine/engine bay from all sides with this placement, losing that wasn't worth saving a few bucks on driveshafts to me.
Dirona I agree. Thanks for the reply. How’s the power off-road and freeway travel? I hear guys complain it’s too sluggish but I’m not trying to go more than 80mph, or go 0-60 in three seconds lol. Trying to avoid the guzzling 5.9 if I can.
I am doing a 5.9
Right on. Well worth the effort!
I wish i could do that to my jeep that was awesome
Thanks!
@@dironaa did you kno u can buy a brand new crate motor ( coyote ) V8 3.0 from walmart now lol $8999.00 lol i tried to add it to the wifes grocery list she said said sorry it didnt fit in the buggy or she woulda got it for me lol
LOL! Was worth a shot!
Awesome work looks really clean
Thanks!
How much could you build me a wiring harness for
One meelleeon dollars. As much as I'd like to help, I wouldn't feel comfortable building a harness for someone else. There's is a lot of good information on jeepforum.com to help you build it yourself or there are some actual companies out there who would also build it for you.
super clean look. what differentials are you going to run? I have a old ram 1500 with the 5.9, I was going to swap the diffs underneath the truck onto the jeep
Thanks! I'm running a stock TJ Dana 44 rear and Dana 30 front. Unless you plan on throwing performance parts at the 5.9 and beating the snot out of your rig I'd expect a d44 to hold up just fine.
Dirona that’s kinda what I was thinking too with the 44. But I’m going to build it to use it in the woods and have fun. I’m going to be running at least 35s or 37s.
Why on earth would anyone swap a wore out engine into anything??? It would be a simple matter to rebuild it before you install it. Now you get to take it out, rebuild and reinstall.
Good question. In the back of my mind I never really planned on keeping this engine. I'd like to build either a 5.2 or 5.9 from the block up with a mild cam and some performance mods but wasn't willing to dump that money into the engine before knowing for sure that I'd be able to make the swap work. In reality pulling and installing the engine was one of the easiest parts of this swap...the wiring, fabrication, and adapting of non-standard parts is what took 98% of the time and effort involved.
Swapping a rebuilt engine with the one currently installed should only be 3-4 hr for removal and the same for install, which is next to nothing compared to the mass amount of time involved in the swap as a whole.
The short version: for me, it made the most sense at the time.
The nv3550 has been holding up fine to a stock 5.2. And I rebuilt the 5.2 fully and still holding up. I swapped in a rubicon Dana 44 when I had my 2.5. It didn’t last. I now have a 8.8 and the stock traclock with a cobra clutch pack. I broke the spider gears. But over all like the 8.8 and would recommend it
103,000 miles on a well maintained engine isn't a lot. I've been getting 250k to 300k out of my cars before I get rid of them..........................still in great running condition.
Wore out? 104,000 is not even close
What was the part number of the header you used
I can’t find the receipt but it was a plain steel Summit Racing block hugger header
What size exhaust are you running? What kind of muffler? It sounds good. I just started mine for the first time today
Congrats. I'm running 2.25" from the headers to a y-pipe, then 2.5" the rest of the way once the pipes are combined. After a little research ZJ guys seem to think 3" pipe is optimal for this engine instead of the 2.5", but I went with 2.5" because i couldn't find a prebent tailpipe larger than 2.5" (bought from Summit racing). The muffler is also Summit racing brand and came with the tailpipe as a package.

@@dironaa thanks appreciate it
You did an awesome job
Thanks!
how's the Jeep running
Fantastic! Best vehicle I've ever owned.
Sweet color TJ !!!!
It is!
hello I write from Italy, how did you keep your instrument orignal jeep 4.0?
did you use a special electrical system or did you use orignal 5.2 v8 electrical system?
giorgio scacciaferro I done a v8 5speed in my 98tj. I went to a junk yard and pulled a 98-99 Dodge Ram 5.2 5speed harness. And sliced the two together. The gauges have a different like ohms stuff called the bus. You can look on line or I have the websites for them that will let you know what computer will talk to your gauges.
www.hotwireauto.com/?page=mopar-eng
If you want a factory ac set up let me know. I can tell you what you need. I done my 98tj 5.2 5speed.
That would be great! I presume you had custom lines made?
Dirona
I wanted every thing factory like. So No ish’ I took a 98 Dodge Dakota 5.2 line off the ac pump plugged into the Tj condenser. Tj stock line from the condenser to the stock Tj evaporator. Then from the evaporator to a 98 dodge Dakota drier. From the drier back to the ac pump will be a female to female ends. Went on eBay and found the crimp on male end for the ac line. I cut the hose to length and had the end crimped on at o’Reillys. Now the heater box out of a xj is the same as a Tj. So if you want the 100% right box then junk yard a 97 plus xj.
Dirona you can pm me for pictures and more.
Dirona
eBay it’s called- male springlock 45 degree aluminum crimp of fitting part# BL-4317
It was only like $8. The battery and drier is super tight. I slide my battery all the ways over to the fender. And had to make a bracket to hold the drier. After I installed the condenser I had to make a 1/4-1/2 spacer to mover my radiator back so it would not rub. But all my stuff was off eBay so it could just be mine.
Did I ever sent a picture of the ac set up?
YEA ITS NOTHING NEW BRO, I HELPED MY EX ROOMATE DO IT TO HIS 89 WRANGLER WITH A 400 BLOCK
Must have been a beast!
@@dironaa it deffinatly catchs eyes from the sound of it.

What o2 sensors are you using? I have one upstream and down stream in my swap like what the 5.2 calls for but the connectors to them aren’t the same connectors as the 5.2.
I used the TJ o2 sensors
