This is much better than any modern day showroom heep! Jeep died in '06 when the last TJ and LJ rolled off the assembly line. Your TJ looks brand new, I've never seen a cleaner undercarriage, top to bottom, this Apex TJ is immaculate. I'm partial to the 4.0 I6 but that 4.7 Stroker with all the other exhaust upgrades is tough to beat and totally badass.
i’ve watched every video for the 4.7 build. I think i found my favorite guy on youtube lol i have a 1998 tj that used to be my daily for 4 years that has been sitting for a year and was about to go down the turbo route and probably blow up my engine to be honest 😂 But i was getting a turbo kit for torque. (For trails etc.) i want my daily driver back so bad and recently got discouraged bc of a knocking and having the engine previously worked on i think the mechanic was out for a cash grab and didn’t rebuild it right. therefore, making me feel like the jeep i worked so hard on was permanently messed up bc of the boring job or whatever the crap he did to it. ANYWAYS, i just want to say thank you for your series bc i am purchasing the Amc-288LB-2 from S&J and with the help of your videos try to do the engine swap myself. I agree with you on original numbers not being that important on the motor bc i have ZERO plans on selling this jeep. I’m 23 and plan on giving this to my son.(not that i have a son but to pass on to him type of thing when i do have kids 😂) Also i’m in georgia and was trying to figure out where rick was that helped you out? i saw some east coast references but nothing specific. I really think this has been the most influential youtube series to affect me. thank you for keeping the jeep community what it is by your videos and helping others out. You forsure helped me out. jack
A jeep with an LS is just amazing.. BUT is never as cheap as you imagine or people like to think, ever; and is not the main drivetrain, its the little things that WILL nickel and dime you to death. And a decent build stroker its a BIG upgrade from a stock 4.0 and you can go turbo later for some crazy gains if you want and the best part? EVERYTHING bolts in like it was before, big pro on that
@@yepitsme431 the biggest issue with mine is I have 32rh. I'm curious what type of gas mileage the strikers are getting. I don't expect great number since my stock 4.0 get like 12.
@@jesterofatlas5749 dang bruh you might need some work. my 2005 4.0 4 inch lift 35s gets like 17. I’ve pushed 23 mpg on the hwy if I’m really light. But my jeep is near bout rebuilt. Brand new trans, brand new cylinder heads and headers and intake. New piston rings and oil pump. New drivelines and diffs front and rear (4.56 gears). New ball joints, coils, softer shocks, tied rods/drag link. New brakes. Cold air intake/throttle spacer with a fuel map adjustment. My dad got it for me for college. But You shouldn’t need all that to get your OEM mileage back. Could have some cat/o2 issues or a vacuum leak. Could be torque converter wearing out
@@roderickclerk5904 nope. you don't mention what trans you have, but if a manual you have a 6 speed, if auto a 4-speed. the 02 has a three-speed auto that is based on a trans from the 60's.
I had a bored CJ 81 i6 4.2 to a 4.8...got a larger radiator, and threw a school bus heater in the loop, mounted i the back to take care of the extra heat off the bore...i can say right now, the video sound does no justice...you literally FEEL each power stroke thumping away...also had a choke, and could finagle it with the gas pedal to get it to hold at 50mph@1200rpms(it redlined at 3200 no stroke)and would hold 50mph going flat, uphill, downhill, it did not matter as the engine had so much compression and torque...best engines ever in my opinion..just keep it cool, and custom fit a stronger transmission ..that T5 will blow out...3rd will be your power acceleration gear
1 thing about "break in" there is no such thing as waiting/go easy on a new engine, in fact the first 20 minutes are crucial for the rings to seat properly!! start the engine, looks for leaks/check everything in case and then SEND IT !! the rings NEEDS pressure to seat and idling/low load situations DO NOT help them to achieve that
I’d have to agree I out a reman 4.0 in my Jeep and drove it normally but with the 32rh 65 pulls 3500 rpm’s and drove it home in the highway about 30 mins motor still runs like a top
My brother works for a very well known engine manufacturer, all of their engines are dyno tested and are run at full throttle and full load within 90 seconds of being started for the first time. If something was going to blow up, that was when it would happen. That process also does a nice job seating everything in.
Doing HUMVEEs certified rebuilds after 6.5 is rebuilt we bring up to temp as long as the pressures and temperatures are good a broomstick between seat and accelerator pedal wide open for 20 minutes.
I mostly agree. When I bought a new BMW motorcycle, an old German BMW mechanic told me to occasionally turn the throttle wide open for about 10 seconds, and then close the throttle for 10 seconds. Opening the throttle pushes the rings out against the cylinder, forcing complete contact, while closing the throttle causes oil to be sucked up to the rings, cooling them off. Doing this speeds up the break-in and ensures a good ring/cylinder interface. From your description, it sounds like you're lugging the engine at times. I'd be concerned that the bearings, cam and rocker arms/push rods aren't getting enough oil if you're pulling a hill in fifth gear at 1,500 RPM. Even with a fully-broken-in engine, I don't think I'd do this.
Right on Brother. Your Jeep looks and sounds awesome. Congrats on getting it done and achieving that childhood dream! 97 TJ 4.0 here, 200k miles… I hope to have mine stroked and running like yours soon! What scanner are you using ?
Nice jeep, how manny hp on dyno? Do you run with 87 gas ? What gears ?, i have a xj with manual transmision 4.9 i will check how manny whp have on dyno
I would only do that if your NSG370 is broken. I have NSG370 and 4.5 stroker in my 2005 TJ. Sixth gear is too high for anything but actual highway cruising speed, but all gears up to fifth spot on in my opinion. I have the B&M shifter box upgrade which tightened it all up as well.
What are you going to do to tune it? I have a stroked motor in my 03 Rubicon and it definitely needs a tune but finding any information on tuning is very difficult. Your build is new but you may find after putting it through it's paces that it runs rich at low rpm and lean above 5k.
Stock pcm and tune for now but I plan to get ahold of Flyin Ryan to tune my PCM using an HP Tuner in the future. It’s running fine for now but time will tell.
Just did mine. Pings tiny bit at high elevation with 87 and 9.6:1 icon pistons. If you're careful and don't run it hard, it's fine. But for 20 cents more, it's cheap insurance, and you get better milage to make up for it.
I had a Cherokee, and a Grand Cherokee both in Patriot bl;ue, and they stopped making it for the 2004 model year, so my TJ is white cause I didn't like the new blue color.
Most likely still running the cat. Removing or opening them up internally, really cranks them up. But could just be the muffler choice, like the other guy said

Frames been repaired. Still a nice Jeep
That's the perfect suspension/wheel/tire setup.
VERY sharp rig.
Just secured a 2003 X from a friend, can't wait.
Awesome build. I will be putting a Golen 4.6 stroker in my 03 TJ next month. Still sourcing all the extras in the mean time.

That thing sounds amazing! I miss my TJ, would have loved to do this.
Sounds good, looks good.
I really like the saddle color interior. This is making me rethink wanting an LS swap.

Also if you've got a new cam and lifters you should really do a cam break in so you don't wipe a lobe. Especially with a flat tappet cam

Cool vid, bro. I have an '06 TJ that love 99% of the time 😋
Got a 2000 wrangler. Doing the same build. Just need to find good shop to do machine work.
Nice build. What is the manifold to injector heat shield? What is the injector rail wrap?
How bout the silicone cooling tubing?
Thanks for posting
I’d love to know your exhaust setup. Maybe some links, if you could.
Right on Brother. Your Jeep looks and sounds awesome. Congrats on getting it done and achieving that childhood dream! 97 TJ 4.0 here, 200k miles… I hope to have mine stroked and running like yours soon! What scanner are you using ?
I have a cheap Innova 3020RS, but I’d like to upgrade to something nicer like Rick had in the video. I think it’s an Autell but I’m not sure.
There's just something about 6cyls over 4.0L that's so appealing. Such a good sound to them. Toyota's 4.5 sounds better than the V8s they made!
subbed. May do this to my 99 some day. I dunno the factory enginr only has 86K and runs like a top. I've had it for 22 years.
Keep it stock.
I’m saving for a Newcomer stroker build for my 89 Laredo. Cost twice what I paid for the Yeep.
Nice jeep, how manny hp on dyno? Do you run with 87 gas ? What gears ?, i have a xj with manual transmision 4.9 i will check how manny whp have on dyno
What transmission do you have?
I’m torn between swapping my NSG370 out for a AX15. I’m definitely keeping the 4.0 as is though. Awesome jeep you have!
I would only do that if your NSG370 is broken. I have NSG370 and 4.5 stroker in my 2005 TJ. Sixth gear is too high for anything but actual highway cruising speed, but all gears up to fifth spot on in my opinion. I have the B&M shifter box upgrade which tightened it all up as well.
@@davidrandall9964 okay that’s good advice thank you!
Where did you get the 4.7 stroker valve cover I can’t find it to save my life lol 😂
I turned the 4.0 cover into what you see. th-cam.com/users/shortsuXR_tZHG8Gs?feature=share
What seats are those? Im looking for something like that for my XJ. Awesome build btw, that thing is gorgeous
Think they were included as part of the Apex special edition. You might find that Best Top makes something similar.
Was your mpg a drastic or minor change?
I like the seats
Apex edition
What are you going to do to tune it? I have a stroked motor in my 03 Rubicon and it definitely needs a tune but finding any information on tuning is very difficult. Your build is new but you may find after putting it through it's paces that it runs rich at low rpm and lean above 5k.
Stock pcm and tune for now but I plan to get ahold of Flyin Ryan to tune my PCM using an HP Tuner in the future. It’s running fine for now but time will tell.
That’s bad ass!!
Thanks buddy!
did you have to dyno or do anything to the computer for the larger injectors?
its actually kinda sad how many people think engine break in means baby it and give it 500 miles
Where I can purchase the engine? Do you have the link? Thanks
Golen Engine Service in New Hampshire..
@@ManicPandaMedia No, I pretty sure he said it's an S&J Engine, not a Golen.
Engine break in is cam for about 30 minutes, the piston rings expand with heat. Bearings are torqued to spec, nothing really else
Just following my engine builder’s instructions.
Is it fore sold
Sounds great. I have a 4.0 that I swapped into my CJ7. I've been thinking about stroking it. Does it ping if you use 87 octane?
I haven’t tried 87 but it is recommended to use Premium fuel.
Just did mine. Pings tiny bit at high elevation with 87 and 9.6:1 icon pistons. If you're careful and don't run it hard, it's fine. But for 20 cents more, it's cheap insurance, and you get better milage to make up for it.
I love patriot blue
I had a Cherokee, and a Grand Cherokee both in Patriot bl;ue, and they stopped making it for the 2004 model year, so my TJ is white cause I didn't like the new blue color.
Does this engine require premium fuel?
Yes it does
Is that a Rock Hard 4x4 bumper?
Front bumper is an EAG. Rear is Rugged Ridge.
What are the wheel and tires specs and sizes!?
th-cam.com/video/kWk9id_pqsw/w-d-xo.html
hey what rear bumper is that???
Smittybilt SRC
Engine is quiet...I thought it would sound beefier..
That is dependant on exhaust and muffler.
Most likely still running the cat. Removing or opening them up internally, really cranks them up. But could just be the muffler choice, like the other guy said
looks great!, stop dumping oil back into your intake
Ok?
Catch can?
Apex edition!!!
Nice 70s porn music intro 😅
Nothing flowmaster flows worth a shit. It’s just sound.
My Honda CRV could take that trail.
Who drives Honda CRVs? 🙄
Hmmm I wonder if it has a 4.7 stroker??🤦♂️🤡
