So i was at the Junk yard todayy, and i was lookin for some parts for my xj, and while i was leaving this mercedes benz cought my eye, and i went to go look in the engine, The whole turbo kit happen to be on the car and the motor was an inline 6. so i took a look at it, off coarse it was really rusty. but i can just sand blast the rust off. any ways, i was doing some research on line a few weeks ago, and i saw that there was a XJ with a 4.0 Inline 6. witha turbo kit on it. So i was wondering would this work if i put that turbo on mine??
P.s mine is a 1988 jeep cherokee laredo 4x4 4.0 Inline 6.

Dam i was just asking if i should, i do know alot about turbos, i just wanted to know if it would be a good idea, or not. and your trippin about it. yeahh you do have a point we do need more bottem end torque. but when your xj doesnt go over 80mph it kinda gets annoying sometimes.
lol and i do have a point there.
lol and i do have a point there.
What trim is the compressor wheel? And the hotside? What does it use for a wastegate?
You know am just thinking of puttin it on becuase of the wistle noise it makes. and yea i could do that becuase i have done it before. all you do is hook up your headers with the turbo connection, and lead exhuast and your there you go your turbo doesnt really work, but it stills makes the wistle noise. lol Yeah it might seem stupid to some of you, why do that if it doesnt work, well there are many reasons why, and then other people think its a good idea, I dont have the money, but i do have the turbo, and all i would have to get are the headers for under $100 online.
This HAS to be the absolute dumbest thing I've ever heard, especially in respect to turboing a car. I just can't believe you said this. Hooking up a turbo to a cars exhaust and doing nothing else is just plain idiotic, esp if only for the "turbo whistle". This also backs up my thought that you have no "skillz" other than what you learned from watching a few "Fast and Furious" movies.
So please, just stop.
I do know how they work, I've worked on many turboed vehicles like Skylines, 200SX, Silvia, etc.
They dont have smooth throttle. Trails I run and I find a majority of people run are a mixture of dirt, downed trees, water crossings, rocks, and mud. You're going to have difficulty controlling the throttle with a turbo and thats why many people dont run them unless all they do is 1 or 2 of the types i mentioned that would be fine to run it in. And thats fine, its useful for those as a power adder.

Otherwise all the turbo diesels you've suggested would also suck off road.
This can be solved by not running a traditional intercooled setup, or just using water to air intercoolers.

But you'll never see it without the hood open/off.
I dunno about you, but I don't sit at car shows with my hood up, and I sure as hell don't wheel without my hood.
I guess to each his own.

No, this won't work. I'll explain below.
I agree. Fuel/timing management, fuel delivery, plumbing, etc. Typically those who ask don't need to even try.
If you have the "skillz" then you shouldn't ask. If you have the "skillz" then you'd already know that turbo of the 'Benz isn't gonna work, and even if it does, it won't work well. Its made for a different car, and has completely different characteristics thank what you'd want in your Jeep.

The throttle issues are all because of poor engine management. If you did the setup right you wouldn't have any issues at all. I strongly suggest staying away from any sort of piggy back system. Stand alone is the way to do, hands down.

I think its pretty obvious though that in this case he would most likely piggyback it instead of using a stand alone setup.
lol i know wayy more about import tuners then you will ever know in your life time which means i know way more about turbos to, ive installed so many turbo chargers on so many cars that i have lost count, i work on them everyday of my life, we even have a shop just for that kind of stuff. yes that turbo from the benz would work perfect, and yes that was a stupid thing to say, that hookin up the turbo to the exhuast is dumb i got you there. the only reason i posted this up, was to see if any of you guys ever heard of an xj with a turbo charger and if it ever worked ok.. so next time you decide to be smart, think again. Oh and ive known about turbos way before the first 2 fast 2 furious movie came out! So How bout Please Just stop. thanks
Obviously it would theoretically work but you'd need to basically just use the housing and custom make everything else.
Maybe you were tired but the way you asked in the OP did make you sound like a 17 year old kid that just finished turboing his civic and wanted a new challenge.
No disrespect meant from me.
Btw thats not an XJ body, its either a YJ or a TJ but still the same engine.

We all said its been done and it can be done, but the only thing useful out of the merc is the turbo unit itself.

to turbo cheap is a pain in the *** yu need steel crank and fordge rods and pistons and tighter vavle springs reflash the computer just to run like 5psi then it cost more likke speical head gasket andbigger injuctors and better oil pump the yu cant go mudding with it cuz turbos cant breath dusty air the turbo its self gunna probaly need to be rebuilt for it to last if it blows up there gos yur whole top end and pistons and it the benzs was a deisel the turbo wont work cuz there only balanced toe like 50 000 rpms the gas jobs need like 150 000 rpms then yu need a waste gate setup its too much work but i super charger kit its cheaper and will make power from idel up turbos only make power from spool up on

But back to topic. Turbos are a cool idea and if you can fab up the manifold (cause i doubt the other motor has the same dimensions for the manifold), piping (again going to be diff) and fuel management then i say go for it. People will say " OH THAT wont work when your rock climbing" but you live in Louisiana so about all you have, i assume, is dirt roads and mud.
The other route is strokers. But if turbos are in your blood and you have the ***** to do this then heck yea do it.
I feel like the devil on his shoulder, I'm the only one for this

I'm not even convinced that the turbo would work. Depending on when you want boost, you really need to take alot into consideration. If you want a reliable, easy to use, and well balanced power setup, you'll likely have to make a hybrid turbo. Use a smaller hotside and larger compressor wheel. None of us know when that "Benz" turbo (chances are benz didn't make it) is gonna make boost, especially on out motors.
If you don't care about drivability and when you make power, sure, it'll "work".
If you don't care about drivability and when you make power, sure, it'll "work".
However another thing to keep in mind is the speed at which they turn, 150 000rpm generally as someone else pointed out(not sure who now) and how long that benz has been sitting there. 150 000rpm rusty piece of metal? Not sure I'd want to do that.
I was commenting that it could be done with regard to doing a turbo setup, not convinced it could be done with ANY(now that i read its a diesel i dont think the turbo itself would work either) of the parts would work from this.
PM me when you start your build, I wouldnt mind reading about another turboed XJ. I think for mine its going to be a stroker once I go over 35s and am planning for a supercharger to be added once I hit 39s. Ofcourse planning ahead accordingly.

Not to mention that about 98% of the junkyard turbos will be SHOT. I can guarantee the bearings are shot and/or the exhaust ceramics are cracked.
I pulled quite a few from the local pick-n-pull over the years looking for a good one for a project I have on the back burner. ALL of them have been completely burned up or at least needing more parts than I am comfortable replacing.
Here is one of MANY compressors that I have removed from all the whooped junkyard turbos. It's now a desk accessory for me. Its a compressor wheel from an Eclipse turbo. T25 I believe. I tossed the rest of the turbo guts out a long time ago.

Someone mentioned that its a diesel too after I reread. Not sure about those turbo setups but I'm pretty sure i read somewhere that they are much different than the turbos I've worked with. So you're probably right it wouldnt work.

I was more getting at the fact that the turbo he found could be any turbo. It could be a small turbo meant for a 2L 4 cylinder. You stick that on a 4.0 I6 and you are going to out run that turbo at idle. It just won't let the exhaust flow. Its like taking your exhaust and turning it into a coffee straw. It pinches flow so much you LOSE power.
On the other hand, it could be a bigger turbo. It could take forever to spool. So long you'll never make boost. And that is just as bad.
If you were to turbo this motor, and want if for off road use, you really need to do research and find what will work. They don't all flow the same CFMs.
I'll be doing this on my fiance's TJ. The XJ is going to be the "relaible" DD for us, and isn't going to be the "monster" the TJ is going to be. I'm happy with a 3" lift on my truck, but the fiance wants a minimum of 38s, and a huge lift. So its gonna end up being on the much-hated-by-XJ-owners Wranger TJ.
I can do a generic Jeep 4.0 thread when I have all my info lined up, or put it into the "other vehicle" branch or something.
A teaser, though...Ford injectors, Wally 255lph or Aeromotive A1000 fuel pump, and most likely a Mitsubishi 16G/18G/20G hybrid turbo, but most of this is all up in the air as I'm still doing the research.
And its gonna be a low compression stroker to start. I found tons of motor options for a stroker, and I'll be using the 8.75:1 setup found at the top of the list just below this txt...[injectors and FPR will be different once turbo'd]
