the way torque comes in on a turbo motor really helps transmissions survive. Usually higher in the rpms and after the shift when load and boost start to build. Low rpm torque pulsing destroys transmissions
Turbo vs engine swap
- Thread starter Gollywomper
- Start date
OP
The issue here is experience and learning curve. I’m bound to burn something up while learning.
OP
I like the turbo idea a lot. It just seems a bit exotic as I have no experience with them other than my eco boost 3.5s. Had 2 F150s and a Transit van for work that weighs at 9k lbs. 175000 miles and it still pulls well.
My brother settled on 35 spline axles and arb in his tj 44 rear and rcv's in the 76 ford hi pinion 44 i narrowed for him. He drives pretty easy and that combo has held up well behind his 5.2/auto and 36s
OP
Wheel speed tends to increase with more HP. When you suddenly bind those wheels that energy must go somewhere. Lol

Most of the stroker amc failures are valvetrain related. Its hard to get quality valvetrain parts.especially when you go for aftermarket aggressive cam profiles like almost all stroker builds use. I went with a custom ground nitrided comp cam and I'm not happy with the lifter noise.
Again I'll disagree on costs for each swap but I also haven't researched doing a LS swap in a few years.
Not having the AX15 doesn't matter. Any LS transmission is going to require an adapter which is added expense. And doesn't most LS engines require some sort of specialized tools for working on them? I don't care if it's a LS/Hemi/Magnum if it's got more than 100,000 miles on it I'm taking it down and at least adding new rings /bearings /gaskets.
IMO this isn't an obnoxious exhaust note and wasn't loud on the trail. This was my 5.2 & a 2.5" exhaust all the way to the rear.
Now the current exhaust on my stroker is louder but I don't have a tail pipe on it yet.
OP
totally unnecessary on an LS,they last 3-400,000 miles if not abused. The 6.0l i put in my 70 k20 chevy had 260,000 miles on it. Perfect oil pressure and compression. Apon teardown everything was perfect. There was no need to do so. A friend spins his junkyard LS to 6500 rpms with only a cam,springs and rocker pivot upgrades.
They are in different league.just like the modern hemi has left both the ls and especially the magnum behind.
The multi displacement systems can be an issue. But both the hemi and ls have versions without and can be converted easily if they have it and you want more reliability and don't want 10% better fuel mileage
OP
According to RedRock, A hemi swap with a nv3550 would net 2” longer driveline as it actually moves things a bit forward. Being my 2.5/ax5 is shorter than most other combos I would guess it would be about the same.
Well, since Ryan rubbed the lamp...
I think our buddy wranglerfix would have something to say about that one.
Depends on how you wheel. Power makes a big difference in many situations. Makes a huge difference on my rig, and in many of the places I wheel.
You are entitled to your opinion, and you do you, but you can certainly build a V8 jeep which does not sound obnoxious. I've never heard that comment about my rig.
Depends on how you build the rest of the Jeep. Blanket statements are rarely correct. I certainly don't wheel like a grandma, and I've certainly not broken pretty much everything.
I run a built Hemi, and know a good bit about them. I love kidding back and forth with my LS buddies, but I would never say the modern Hemi has left the LS behind.

Ford seems to be getting left out. My bold plan is to swap in a Coyote engine into mine.
JK. Fords suck.
yep. Blanket statements without context can be picked apart. Here is the context you missed
1)if you go to autozone,ebay,etc and get a "rebuilt" cpu good luck...
2)sure it does. But on o.p's (the subject of our discussion) or most tj's any stock v8 or even 4.0l will do. I'm leaving hp levels out of the v8 debate.and not unreasonably to head off a 5.2l low end vs LS top end discussion. ANYTHING is going to improve on a 2.5l
3)noise comfort level is subjective,but you won't fit a large enough muffler under a tj to make a v8 factory quiet.I hunt with my tj,it needs to be close to stock sound.that eliminates ALL v8 swaps.sorry,no getting around that.i would indeed find your jeep obnoxious if i had to follow it on the trail all day.nothing i can do if you don't like that
4)again refering to the o.p's jeep in particular and most tj's you WILL need to upgrade many things for the new power.not sure what you are arguing on that one?
5)the newer 6.4l hemis are a whole different animal than an ls. Factory flow numbers and power potential is awesome.don't get me wrong i love my ls motors.but i see a lot in the new hemis
I see you hopped in to try to refute most of my points.thats your prerogative. But you aren't saying anything that compels me to reevaluate my standpoint.
At the end of the day its dorks on the web giving their opinion.

I did not miss the context - you provided no context, which was my point (in fact, you did the same thing several times in your response to me). You made several incorrect blanket statements while providing neither context nor supporting comments. You are not terribly active on the forum, and many of us don't know you from Adam, nor have any insight as to your level of expertise. But you did seem intent on arguing - particularly with Rick.
It does seem like you have some experience, but maybe work on your delivery just a bit...
Again you experience is different than mine.
If a 4.0 will do then why do a stroker or a V-8 swap?
Again I disagree. My 5.2 exhaust wasn't loud or obnoxious and hardly much louder than many of the 4.0 Jeeps I wheeled with.
I've known more than one person who did a V-8 swap and didn't upgrade the rest of the drivetrain. If you drive with your foot in the floor yep you'll break stuff. Even with the stock drivetrain you can break things. I did with the 4 popper.
Sure the new Hemi is nice but I'm not sure it's all that.
Yep we all are. And just like other things we're all intitled to our own opinion.
I’ve followed @NashvilleTJ on the trails all day. It was such a wonderful experience that it made me buy a second LJ for a V8 build.
And no I’m not making any of that up.

You got me there. I'm generally an azzhole and not a good speaker.
I like ricks jeep,he's doing cool stuff to it. He followed a similar path to my brother.i just wouldn't pick a magnum starting clean today vs 15 years ago.
