Jeep JK LS Swap; Complete How TO

[@jacobthornock317]

6:05 my 12 year old walks bye, pauses, backs up and says, "thats a 2 door gladiator 😮"! I want it." 😅 you are safe for now Ian, as his dream color is vibrant blue or red.

[@realplatinum]

Definitely one of the best engine swap videos I've ever watched

[@BigTireGarage]

Wow, thanks!

[@zmotorsports62]

I put a 6.2 liter L94/6L80 combo out of a 2012 Denali in my 2011 JKUR about 5 years/65k miles ago. Great powertrain for the JK platform. Can I suggest turning your battery and TIPM lengthwise as it really opens up clearance and accessibility to that right bank. Plus allows a bit more airflow around the right head. I'm running GM OEM wiring harness to remain USEPA compliant and even made the OEM GM engine cover to fit. My goal was also to make it look and perform like it was OEM. I used the Motech MoCAN module to create that "handshake" between the GM ECM and the Chrysler BCM and everything functions like it rolled off the assembly line. I used OEM Trailblazer exhaust manifold to clear my suspension and they worked great, still uses OEM heat shields. I would suggest wrapping the fuel and vapor lines where they route from the right frame rails, around the fuel tank and up the back of the transmission as that area gets quite hot on those lines. I also used a NP241J transfer case with the 2.72:1 ratio. With the 4.02:1 first great in my 6L80 transmission, I don't miss that 4:1 transfer case at all. In fact, the gearing in my GM powertrain is similar to the stock JK Rubicon gearing ratios but with double the torque. Drivability is freakin' awesome, both on and off road. Drives like a Denali with a Jeep body on it and everything functions as designed. Utah has pretty strict emissions guidelines and it passed all USEPA requirements for Utah licensing. I'm running 4.56 final drive gears and with my 37" tires and 33% overdriven trans. my cruising RPM is 2k @ 70 MPH. Returns decent economy, better than the stock 3.8 liter and 42RLE combo on 35" tires. You're going to love it more each time you drive it. 👍 Mike

[@BigTireGarage]

Thanks for all that info I will definitely look at all those suggestions...I like the idea of turning the TIPM and battery

I love your videos. One small complaint, I find myself constantly turning the volume up and down all the time between your monolog and the music. The music is way too loud, is what I am saying. I am more interested in hearing what you have to say than the music. Frankly, I think a lot of people make this mistake, I personally would not miss all the music people play in the videos. It gets exhausting. No hate, just my opinion. Carry on. You're an awesome creator.

[@BigTireGarage]

Glad you are enjoying watching

[@Spanked78]

I coulda swore I read an article or a forum chat from a Jeep engineer years ago that the reason a 5.7 Hemi bolts in so nice and clean in a JK is because they originally planned to offer that powertrain, but because of government mandates, safety issues, and so on, they scrapped it for production.

[@BigTireGarage]

I would believe that...and with the 392 available now it makes sense

How you explained the wire harness and how the computers need to communicate with each other was extremely enlightening.

This one was chocked full of solid information, Ian. The huge plus was Zelda making her cameo; she's so adorable and looks just like our Gabby we lost 3 years ago so thanks for including her! Lastly two things; the burnout was epic and you better get some anti-aircraft radar and countermeasures in the shop. You were buzzed by a pterodactyl @46:54 which rivaled a B-52 in size. Looking forward to the next video and seeing Zelda make another cameo! Cheers!

After seeing how much better the constant tension clamps are I would much rather use them than the worm gear type. But if the heat shrink ones work better then go for it. I like the constant tension clamps because they don't tear into the hose like the worm gear clamps do.

[@koreykilburn5303]

California the only way I can V8 swap my JKU is with a Hemi. Since I have a 2015 JKU the Hemi has to be a minimum 2015. Engine swap has to be same year or newer as vehicle and has to be same manufacturer as vehicle. That is unless it's a pre smog vehicle then the state doesn't seem to care as long as it isn't a gross polluter.

[@StormbornJKU]

Seems like you had to do a lot of “custom” stuff for the engine to work like factory in a vehicle that it doesn’t come factory in. From my little bit of research, I’d say the hemi is more plug and play. Americas most wanted 4x4 makes kits that essentially “bolt in”, making it super easy to swap. And I believe the company is called Motech, and they specialize in LS swaps. Last I saw they got it to where you only need 1 computer, and basically made a more plug and play style to their engines as well. Of course,I’m no expert, and you absolutely know a hell of a lot more then me when it comes to anything vehicles. But those 2 companies are for sure the number 1 companies for plug and play / easiest to do engine swaps for the JK.

[@BigTireGarage]

I looked at the Motech kit and it was "in my opinion" the same amount of work....and was considerably more money

[@Lifeat90]

I could understand this in a 4 door jk jeep...but in a short wheel base like my little tj.how you would use 500 hp from a ls swap would be scary.my fresh 4.0 is plenty

I We are not the level of craftsman you are so, It was better for me that Robbie at MOTECH had done all the heavy duty fabrication & fitting. I went with the 6 speed trans because of cost.
