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.

there ya go, read that.... tons of info on installation and the power gains...

i personally think it would be a waste of money, but thats just my .02, there is already enough power for a mild setup/equipped jeep, unless you plan on running some monster huge tires and etc.... i wouldn't bother

 

plus the fact that if you plan on wheeling and have a turbo with an intercooler it would over heat constantly due to lack of airflow, if you want to spend the money to add power go with a v8 conversion or a supercharger kit that doesn't need an intercooler

 

I would pass on a turbo especially if you have never mess with one.

The thing I would suggest if you were going to spend any money on a turbo, supercharger or the like would be doing a 4.7 stroker out of a 4.0

 

Ebay turbo, fit it up with some JB weld and old exhaust pipe. Works great.


In all honesty the only person I ever knew who turboed his Jeep said it made it funky as hell to drive and hard to control the gas while wheeling.

And if you are doing it for street performance, that is just dumb. Dont buy an XJ for street performance, it is like buying a Ferrari to offroad in.


The only way I would say it is a good idea is if you were to swap an engine that has a turbo from the factory. Like one of those Japanese I6 performance engines like a Nissan RB or Toyota 2JZ or a turbodiesel of some sort.

 

now on the off chance you get extremely extremely lucky and find an old comanche that has a turbo diesel in it then you would be set but otherwise, like you may be able to tell by now.... waste-0-time and $$ (for a jeep)

 

Theres a guy on pirat4x4 that has done a few turbo set-ups on 4.0L and has a few good writeups/builds. His jeeps are mostly desert racers and seeing his TJ do huge donuts and roster tails makes me kinda want a turbo jeep.

I say do it if you have the time, money and skill. be different

 

I kinda dont have the money, i do have the time and the skillz, iv been working on import tuners for most of my life, so am not new to turbos installs and specs.

 

Well if you're familiar with it then you're familiar with the TYPE of gains you get. We need bottom end torque not top end power and with how erratic the power is with a turbo its pointless in an XJ.

If you have the skills to rebuild an engine, stroke your 4L. It'll be just as powerful, if not more, more reliable, smoother throttle and less of a pain in the *** just for the sake of being different.

If you want to be different put your XJ Drivetrain on a Honda Oddessy body. lols.

 

^ ?? do you know how turbos work, you can get turbo's to spool at 1500rpms if you wanted. Even if it spooled at 2300+ then normal driving wouldnt produce boost and suck down gas but when you need the power you have it on demand

It really comes down to type of jeep you have/want/need. A DD, turbo would work fine; desert racer, perfect; mud monster, would work great; rock crawler and small trail rig, not so much

 

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.

 

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.

 

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.

Didnt mean to **** in your cereal, I was poking fun at someone else on here a while ago that wanted to put a honda oddessy body on an XJ.

You're better off gearing your XJ and or stroking.

Not something I'd want to do to my XJ but as far as aesthetics go its really up to the owner. Some people like putting chrome on their XJ and thats their prerogative

 

If you want the whistle noise just buy the exhaust inserts they sell, a lot cheaper than $100. http://www.turbowhistler.net/
I don't really get it but its your Jeep.

 

lol i bought one of those a while back, and it worked for about 2 weeks then it dident whistle any more. plus you can tell the whistle doesnt come from the engine.
