You are wrong, it is easy, and cheap. Just takes common sense, and a basic understanding of turbo's, plus a little research.
Reread everything i posted. I gave options. He can use megasquirt, or a piggy back afc. Look at the 306ci engine on the stand in the pic i posted. The turbo is connected to both exhaust manifolds, but is on the passanger side. You can, and should do the same on a 4.0L because it would be stupid to create alot more heat under the intake manifold.
As for intercoolers, i also gave options. The mustang, and my rx7 both create way more heat than a 4.0L, both of those cars make alot more power, and both cars run full size intercoolers infront of the radiator. The rx7 has ac too.
The bottom line is that there are options, and for a low budget, low boost game plan. It can be easily done except for the exhaust manifold fabrication (which in reality isnt that hard at all compared to putting a real lift kit on an XJ)

maybe you've had hands on experience for quite a while & YOU feel they're easy, but if it is in on XJ/TJ/YJ/ZJ/WJ's 4.0L Inline 6, why aren't there more an abundance of them out there??
not trying to be a d!ck to ya... i do basically understand turbo systems, & i WILL be tearin apart my girls' Mazda P5 to boost it (till it blows, then i'll swap in the infamous rotary) & as easier as my XJ is to work, in general, i already can see boosting an engine with the intake & exhaust in separate locations a lot easier to work with
Yea but a moostang and rx7 dont have coffins for engine bays.. The tight fitting, poorly ventilated design of the cherokee engine bay doesnt necessarily allow for the "ease" you that you've experienced in other applications. Basic turbo might be an "easy" set up for you, or so you think. But the dynamics specific for a XJ make it a bit tricky. Gee oh Dee does make a valid point as did I with being hesitant with a front mount intercooler. For a cheap, low boost, non intensive set up you're theory of a small intercooler might work. But that could be contradicting to what we are pushing for: Do it right, do it big.
I say if you're as capable with turbos as you claim, start a XJ turbo build and help us work out the kinks lol.

seriously grip, i will drive from Connecticut out to Illinois, will buy all the cheap budget components u recommend, & have you set a turbo up in my XJ... I VOLUNTEER MY XJ FOR YOU TO PROVE TO ME/ALL OF US HOW "EASY" IT IS... & i want it to last, not survive a few hundred or thousand miles & something in the system fails

Go look under your XJ. Check that side out. See how many bends in the pipe you'd need.
My point is that it's NOT easy. And not gonna be cheap.
And this Grip kid knows next to nothing about XJs. He's comparing his RX7 to an XJ in respect to the cooling system.
Think about that a bit.

Jesus christ.
First all i hear is "put up or shutup"
Now its all "its to hard, its to expensive, there is no room in a jeep engine bay"
I gave options, just like anything else. Do some damn research instead of complaining or arguing about it. Use a little common sense, use a little imagination.
It can all be easily done. But like i have said before the hardest part will be ex mani fab.
No room in a xj engine bay? Have you seen some engine bays out there that people have managed to turbo?
Stop crying.
Or keep speading how hard it is to do, and recommend regearing because that is easier. Maybe thats why people dont turbo the XJ more often? Or maybe its because people looking to buy a jeep usually arent looking to make gobs of power at the same time?

You are still on the cooling thing. I allready gave options for a low boost setup.
If you think the notoriously very hot running, cooling unefficent rx7 is no big deal compared to an XJ. You are wrong once again.

All you can spit out is 'do your own research'
Sounds like you can just spit the basics, and have no resolution to the real issues folks that have done this have run into.
There are several threads on several forums that have turbo'd XJs.
They have all put serious time and money into it. There is even a guy on here doing it.
But to make an efficient and reliable system, its not gonna be a back yard hack job.
So until you actually do this, all this garbage your spitting is just word of mouth. No real experience with the XJ platform.
So it os just that, garbage.

That's how they did it on one of the really big vehicles I did drivetrain management for. I seem to remember that style of mounting on some sports cars, as well.
I'd guess you're going to have to mount the turbo toward the rear of the bay off the exhaust header, and run a CAI from the cowl. Compressor output goes to the intercooler on the driver's side, then up to the throttle body.
Personally, if I were going to boost my XJ, I'd go for a quick-spooling low-boost install. I'd want to enhance the lovable characteristics of the 4.0L--boost coming at 1000 or 1500 RPM, with a nearly flat torque curve out as far as could be managed. Not wind up with some peaky, nasty curve that's only good for big numbers on a dyno run.
I suspect that would not be an easy thing to accomplish.

Oh, and if you're boosting, you've got to consider the rest of the drivetrain, as well. How much torque are you going to generate? Can your clutch handle it? What are you going to do about axle wrap? If you can squeak the tires, you can wrap the springs.

Ive seen a couple builds where the person mounted the turbo where the air box is that would prob be easier then on the passenger side or building a manifold for the turbo to sit on

Wow, this has gotten out of hand. Anyways, you could turbo an XJ, but it would be some work. Depending on factors you may need to upgrade the entire fuel system, and running a 3" or so exhaust under an XJ probably isn't going to be easily done. It would seem you would need to to a liquid charge air cooler for packaging purposes, and then run a seperate cooling system with a electric pump. I dunno, seems like a lot of work for not a lot of return on a stock engine.

Grip im gonna quote you from another thread here. "Get over yourself"
If all you can say is use google and do research you probably shouldnt waste your life typing anymore. Your an arrogant pompus *** who likes to think he knows everything and its pretty clear you just want to make yourself feel important. Sure you may have turboed that tampon maybe ya didnt who knows, but you clearly dont know anything about the subject at hand being xj's. You need to get over yourself and realize that you dont know everything about other peoples mods because everything is different and every mod is different, so quit posting like an arrogant f**k because all your accomplishing is pissing people off and making yourself look like an ***. By the way real mature commenting on my build thread because your not happy with what I say in reply to your immature comments. IMO you need to be banned because every post ive seen from you is like this.

For a "family friendly forum" you sure are the negative one with a G.O.D. complex due to the "moderator status"
Maybe try helping the OP atleast once instead of trying hard to bash every single thing i type.
Now i remember why i havent posted on here for the last year.

Look at every single post you have in this thread. Not one time have you even offered a hint of help to the OP. infact all you have done is cry about what i do because everyone else is doing it too.
