What I've discovered is people seem to leap before they look sort of speak. They want it now and have NO idea of what's involved. I've seen so many that were half-assed together or not running correctly afterwards because they got in over their heads.
I've done numerous engine swaps over my 30+ years of wrenching and my LS swap into my Jeep JKUR was the most complex. I did my homework for several years as well as saving up and gathering information before buying a single component. When building my Jeep I used components that would eventually support the higher horsepower of the V8 to avoid having to spend more time and money later on.
Once I made up my mind it took me about 6-months to gather all of the parts I needed. Once I started it took me two weeks on nights and weekends is all to perform the swap.
All of the planning and being familiar with engine swaps is why it paid off. That was nearly 4 years ago and I now have 50k miles on the my 6.2 liter L94/6L80 powertrain and couldn't be more happy with my Jeep. I grin like an idiot each time I turn the key. It drives so mild and docile yet plants you in the seat when the skinny pedal is pushed.
Mine is 100% USEPA compliant and feels like driving a Denali with a Jeep body on it. From interstate cruising to off-road driving it is a pleasure to drive and everything functions like it should from Chrysler such as HVAC, cruise control, etc. even my wife feels comfortable hopping in and driving it.
My goal was to make it as close to OEM as possible and I nailed it.
For those looking to do an LS swap, please do your homework and think long term of what you want the Jeep to do.
My 6.2 LS3 vette motor swap is the most fun I have had behind the wheel of a Jeep. It is not an easy swap but it was worth it. Look to spend $30K or more to do a conversion correctly if you plan to have a shop do the work.
Interesting video on the pro's and cons. :) GOod job, Here's what I ended up with working at home.
Jegs Crate L33 + Junkyard core motor to get all the truck/van style front accessory brackets, Local rebuilt 4l65E, Junkyard NP241 w/super short SYE in a stock length 94 YJ with 4" lift. Holley terminator Xmax with glass dash.
All in with mounts etc, I'm right at $10K. Nothing farmed out. Did it with my dad so priceless. :)
Full Engine+trans+tcase install took 2 weeks, then we spent about 4 months on weekends doing the stuff like exhaust(I hand built the stainless welded 2.5x2 into 3" single out the back, wiring, and sorting.
Got 23 mpg on the first tank... Compared to a 13-16 average on the 2.5 that it replaced. (33's and 4.56)
Its a regular drive most days..
Its also quite and drives sooo much better with that Aluminum V8 in it, with the 5 leaf springs it rose up about 1" in the front. Our rough fooling around we think the 2.5 vs the 5.3 was a wash on weight and the weight moved back a couple inches with the new motor mounts. The rear driveline is 1" longer than the stock Jeep 2.5+AX5+NP231 used. (Rear Dana 44 out of a 87 cherokee.. )
I'm sure when I'm through the break-in miles and ramp the tune up a bit its going to be even more fun.. :)
Tony and team, this is awesome! Such a great topic with information from someone you can trust. I had done a V8 swap plus a friend of mine did one and we learned a lot along the way. But many of those things you are for sure covering which is awesome to hear! Thanks for all the info you continuously provide! Going to really help others who just don't know what all it takes to perform a GOOD v8 swap.
Goal is to LS swap my 79 Jeep CJ7, and do a complete Gen Right 4 link suspension set up. Again… goals lol 😂
great video ! thanks for sharing !
thanks guys.
Great info guys,I'm in the process of swapping in a mild cammed 4.8 ls in a slightly stretched wheel base yj and plan on retaining the ax 15. What are your thoughts on manual trans, I'm not racing just mainly camping and backroading
AX15 will be fine if you're just using it for camping and backroads. Advance Adapters will have everything you need for your swap with that transmission if you don't already have it.
Can anyone explain what trouble they were having with the 6L80 transmission paired with the LS3?
The engineers realized they were running too thin trans fluid so they had to come up with a special GM fluid that is blue.
What’s the name or part number for this blue fluid?
@@gregsmithracing4479 The 6L80/6L90 requires approximately 10 quarts of ACDelco Dexron VI #10-9395.
When switching to the blue transmission fluid can it be cross contaminated with the old (red) transmission fluid?
Do you still recommend ACDelco Dexron VI # 10-9395 for the 6L80e? It’s time for me to change trans fluid and was curious if anything new came out that genright recommends (LS3 with 6L80e)
Hi Jeff, how does your Jeep do with cooling having the radiator in the rear. Big difference over front mounted? Thanks
Hey Mauricio! Great question. Having the radiator in the rear was a learning experience. With it mounted behind the seats I have to find the sweet spot to where it still got airflow at high speed. A couple months ago I raised it and moved it back more and it seems to be getting a lot more airflow and staying nice and cool. Much easier to get airflow when it is mounted up front.
Hopefully this will get to you, missed the live version of the video. I have a 2006 LJ, doing a a LS Swap with a Gen III LQ9 out of a 2006 Escalade. Went with a 4L80e transmission and added a shift kit. Still going to use the NP231 until the atlas budget is approved. Currently 3 linked front, 4 linked rear with Dana 60 front, Dana 70 rear. 40 " tires, and not going bigger. This was a budget build so front coilovers are 14" 2.5 King shocks with adjustable resi's purchased used, rebuilt with 200/250 coil rates, rears are FOA's 2.5 14" with same coil rates. The shocks were originally meant to be used with my 4.0 but decided to swap. What would be a good PSI nitrogen # to start with in the shock and when filling, there should be no load on the shocks correct?? Thanks in advance
You should start at 150psi. And yes, that should be at full extension on each shock.
The difference between a 4 speed and 6 speed automatic transmission is 50% more gears. It would feel like going from a 4.8l to 6.2l LS.
I have a 2016 jk 4 door I'm think of putting 5.7 hemi.i don't need all the Xtra hp with Dana 60s what are your thoughts
Wishing I would have watched this sooner.
ii have an 06 TJ and have been thinking about an LS swap ever since. but recently I have come across the 6=8 clifford twin weber system. they claim 120% power gain for $2k that you can just bolt on to the original 4.0. What are your thoughts on this?
Don't go backwards. Carbs are not great for wheeling Jeeps, they have lots of issues when it comes to off-camber performance. If you need and upgrade stick with Howell fuel injection or Mopar.
Most of Clifford's performance claims are most likely coming from the changing out the exhaust headers. But I would recommend you save your money and go for the LS swap.
We will be talking more on this subject on this Wednesdays 5pm live show as well if you have any more questions.
Great Information!
Holley controls the Lt motors and trans. Love the talks about suspension but way out of term and knowledge for the performance side
What did Bernie say ?
i have heard of them they do good work jkls
No, if your spending 30k ontop of a 60k jeep for a v8. Just buy a rock bouncer.
Hemi: more expensive, less power, heavier, less tunable, all negative except for the name!
