@@jestinmorse8248 It should be a blast, I originally built a stroker and it was ok. But then I put 1 tons, and 40 inch tires, and it was not ok anymore. Lol. We estimate the Lq4 should be around 500 to 550 hp, so that should be better than ok, I hope. I will say there is a bunch a nickle and dime stuff that you don't think about before the build.
For those of you new to the 'LS' World: its the Gen 3 and 4 Chevy Small block, replaced the 350cid from the earlier years. LT already gave us the basics the LR4 (4.8) LM7 (5.3) and LQ4/LQ9 (6.0), TRUE LS engines are aluminum, the LS1/LS6 (5.7) LS2 (6.0) and Believe it or not a fwd based LS4. Theres also a big bore LS7 but thats basically the archangel Michael in engine form. After that then the engine codes get crazy: L59, LM4, L33, LS3 ( camaro 6.2), L99, LSA ( supercharged :3) L94, L76, L77, L96, L98, L20, LH6, LY5, LMG, LC9, LH8, L92, L9H, LY6 (gen 4 iron 6.0 RIchard holdners favorite) , LFA ( not the toyota), LZ1, LS9 AND THEN you get to the aftermarket LSX blocks, like the LSX376 and LSX454 after that chevy went to the 5th Gen Block "LT" which do not share bits from the earlier years.
Very cool but also a incredibly heavy engine. Dry, undressed weight is up in the 700 lb range. A lot of frame reinforcement is needed for a swap like that. It’s not quite as cool but a 1.9 tdi swap is always a good diesel option.
I have a coworker that has a Comanche pickup that we put a 360 Mopar crate engine in. It's done right, using all Mopar parts, except the radiator, including power steering and A/C. Looks like it was made for it.
You are the man L.T!! I've been getting ready to start my XJ LS swap for a year and finally someone legit is doing a build we can follow along with. I always enjoyed watchin you on Trucks. Keep it up man, look forward to watchin this series over and over.
LQ4 is a stout engine. Mine on a stock cali legal ecu dyno'd at 287 whp and 336 ft-lbs , so the numbers arent far off from crank horse rating. and all i got is a 91 shyt cali gas tune and a flowmaster exhaust. so that will do great on the jeep. its geared for that sweet torque
I wanted to LS swap my H3 so bad. Really wanted a LBZ in it. But was WAY outta my budget. But so was a LS. But letting my son total it in 6 weeks was probably cheaper then both swaps together. This Jeep will be awesome
I've always thought of the idea of the "anti jeep" a lowered street machine cherokee with a turbo 4.0 or ls swap would be cool as hell, would tee off a lot of people too haha
There's a blue XJ on here somewhere with 400h/500t coming from the "factory" (stroked) 4.0 via a lot of boost. I think it runs 9's!? Ill try to find it... Found : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XZ4Fa3VsWVA.html
I had a 97 XJ 4.0L 5 speed 2 door 2WD. Weighed under 2900 lbs, and was a hoot to drive. Later in its life, I realized it wasn't going to be going off road as much, so I swapped the tires down to 235/60R15. Dropped it 7/8" with no altering of suspension. Even that made it handle much nicer. The leaf springs and solid axles front and rear weren't ideal for handling, but the absurdly low weight and nice torque covered a multitude of sins.
I have LT1 350 with 4L60E in my cherokee its been holding good in there for almost 4 years after the rebuild. I haul all my firewood home with it too from all over the mountains. you have to manually shift out of overdrive and into 3rd to tow with it
@@jacobadam4556 You don’t need to have it floored to break a 4l60e. That 6.0 makes enough torque you could get it stuck once and you’ll snap the reverse shell. Plus I think this guy is also referring to the fact that Monster transmissions are Junk.
I am looking forward to this! The LQ4 is a lovely motor. Heavy, though - before it's too late, see if you can talk him into an aluminum 5.3 stroked to 383 inches!
I'm putting an LT1 L83 in my 37 Chev PU. doing the frame work now. MII from Fatman and leafs from TCI. The engine is rated at 350 HP. That's gonna be a handful in the 37. It's not that heavy, even with boxing the frame. Original specs had it at 3800 lbs. but that was with the Stovebolt six which must weigh 600 lbs. The L83 is half that.
Cool project! On the transmission if it is a rock crawler it's ok to go overkill big on the cooler. A lot of heat builds up with no high speed driving air flow maybe an extra fan on the trans cooler will help out a lot. Can't wait to see the progress.
Hey LT, if you get to wanting some tables for parts and assembly they foldable party tables they sell at either ACE or Tractor Supply are usually around 30 bucks, sturdy enough, and foldable when not needed so you can get them out of the way. Hope that is a helpful resource for temporary work surfaces!.
Cool thing about this upgrade is it will probably get better gas mileage for sure won’t change. Those in line 6s are cool engines, my 91 YJ max torque and hp was around 2k rpm. Like a gas powered diesel. Had a mind splitting 120 hp and torque. Not much worse than a 85 Chevy 305 truck engine 😀
you could add to the series an itemization of cost down to the nuts and bolts so we all know the whole deal, also at 37" tires he's already under geared with 4:56s, he should be running at the very least 4:88s or 5:13s. on a XJ, the general rule of thumb is 4:56s for 33" tires. he should have just used the AW4 jeep trans, theyre basically bullet proof and easily handle 4-500hp
Can’t wait to see the progress of this build. I’m thinking of doing the same for my XJ. Can you list the exact parts that were used from LS Simple to make up the accessory brackets? I visited their website, but was confused on which parts are suitable for an XJ build.
the v8 from a lexus ls 400 from i think 95-97 swaps right onto the original auto tranny but with the lexus trans pump , because the output shaft is slightly different, and you can keep the original gauges
Those tires are way overpressured with a 5" contact patch. Do the circle track test. White shoe polish across the tread,( outside to outside) Lower pressure till the outside white disappears. Thats the pressure for your combo.
Hp to weight on the nose of a Cherokee i personally would have looked for an L33 if the cam and intake were going to be swapped. Anytime you can lose 100lbs off of the nose its a plus, but to each their own. Second why adapt the 231j to the 60e? Use a 231c that would have come in an s10 or blazer. It would bolt up without adapting the input, and it has a stronger 6 pinion planetary carrier over the 231j 5 pinion.
@@LawrenceTolman oh i understand that, i deal with people that do things the hard way too man. I can understand the 6.0 more torque thought but heck even a 4.8 doubles factory power lol
Damn looking at a solid $10,000+ in parts alone. I’m sure I’m way off on that estimate. Id be very happy with 50 extra WHP on my Cherokee with the 5-speed. Would love to do a budget LS conversion or maybe supercharge.
Another you tuber did this conversion on a commanche same as a xj in the front and it was not a easy task a d still has issues with overheating to this day
It urks me seeing non mopar engines in mopar shells but its done by you so its acceptable. a 5.9 magnum can make decent power for reasonably cheap and should bolt in with factory V8 xj mounts
I was just talking about the terminator x max last night. Can it control a sniper setup or only a multiport setup? I would have rather used a single standalone controller for my trans and engine rather than 2 separate ones that can't communicate.
Literally sold my cherokee a month ago. Blew up the straight 6 and put a new one in. Then bought myself an ugly truck. I’m living your world backwards hahaha
The Bore between the LR4/LM7 is the same, the stroke between the LM7 and LQ4/LQ9 is the same, the LQ4/LQ9 bore is different from them. I still would of had the 2008 intake on the LQ4. 4L60, I'd upgrade to 4L70 or a T56
This is great! I have been on the fence for this swap for years. I really wanted to use a gen V/L83 just because they are so cheap now but there are no swap kits out there. I like the novak stuff but the headers are made by sanderson and are just repackaged from Novak....I wish someone could read me the part numbers off of those headers! 4L60Es make me nervous but I agree with the gearing for this project. Any more info on the accessory relocation kit from LS simple? Hopefully it is cheaper than the Holley kit! I am anxious to see if how much of the jeep harness will be left after the Terminator is installed. The factory jeep fuel pump with the old tried and true Corvette regulator combo seems to be the hot ticket with this project.I am going to be following this one close!
Awesome project! I would say I agree with some others' concerns about using a 4l60 from Monster transmission. Everything the knowledgeable people and groups that I trust have to say is they are both trash. Even just 400 hp through a 4l60 (and with aggressive offroading nonetheless) may spell an early death.
Notice the orange stripe you still in Tennessee? Just wondering. Should hook up with Ian Johnson, and Stacey Davis do a former power nation chill and build...
I am swetaing the electronic stuff. Everything else I am good with. How will all the accessories work with this swap harness? Is it fairly staight forward? How much was your new harness.?
I think dude will need to upgrade the axels and add a full cage and sub frame. I’ve seen plenty of cracked windshields from hard wheeling these things in stock from. Plug in 2x the hp and a little bit of traction and the windshield will shoot out of the hole. Don’t ask me how I know this....Looks like a fun build that will keep taking money from this cats wallet for a long time to come.
@@jimmyburks7030 That's useful information.... Dude will definitely need to do some work on the frame or lack thereof, otherwise he will twist it up like a pretzel. We did an LS Cherokee a few years ago and learned the hard way. With the stock open diff is wasn't an issue other than the peg leg burnout clean through second gear. With new axels spinning 5:13's all locked up it was a body twister under hard acceleration. After a hard second gear shift, solid hook up and the windshield blowing out, we kinda' knew we needed to do some frame mods to handle the torque. We tried the BS frame connectors and found out those are a joke and ended up with a full cage, a ton of 1/4" plate added to the entire frame and problem solved. We are running a Whipplecharged LS-3 , NV4500 trans, Atlas 2 TC , Currie 44 with Detroit trutrak front, Currie 9" with a Detroit locker rear.
What muffler we thinkin about? Will it be a single system or duals throughout? This should be a sweet swap edit:. Maybe I should watch the whole thing first
