In one of Petersons 4x4 mag they reveiwed a turbo build by I think 505 motorsports.This build was on a 4.0 jeep motor.

i actually linked the article on page 1 of this over-drawn out thread topic....

but to keep it short unlike what Gee o Dee did (seriously guy who is gonna read your entire comment???)

88Cherokee4x4 before you start throwing up the blast shield and defense weapons you should realize that this is a forum and being such a forum you will get all types of responses from positive to negative, on and off topic encouragement and discouragement so maybe keep that in mind next time your gonna make a new thread.... there will always be haters and you'll always find people that envy... so do what you please.... i've done some pretty wicked trails and have made some damn nifty add-ons for my jeep(s) despite other peoples negativity

Finaly some one that under stands were am coming from, thanks dude

Dude i dont give a dam what you have to say, your like the only one on this whole thread thats being a dick, and saying the negative and oppiste of every one else, just becuase you think an xj cant have a turbo doesnt mean you can go and ruin some one else's party. i know my things about turbos, and maybe so do you. So lets leave it like that. and stop being imature, Thanks

id say go for it. I've actually thought about it myself i think I got it all figured out on routing it an stuff but i think your best bet would be running a small turbo from a eclipse or along those lines so it will spool lower in the rpms. You would also need to run a snorkel to the cold side so no water or mud gets pulled into it

Allright Am done!
Ive made up my mind and am going to do the turbo build!
For all of you that said it wont work. Ill be change your minds REAL SOON!
For those of you that said it will work and want more info on it, then i am going to keep yall updated on my TURBO BUILT XJ. And thanks for the support.
(But keep in mind i will start with the junk yard benz turbo, and if its piece of crap, then i will go and buy a brand new Turbo Just to show yall that i do have the skillz!!)

what everybody doesnt seem to understand its that Gee oh dee is giving the complex information that is required to fab a custom setup. He agrees that a turbo can be put on a 4.0, he's in the process of doing it. But it takes time and research to find the proper setup where you wont run into any problems. . Pull a JY turbo, doesnt matter which you get, clean it up rebuild it if you have to and then fab some headers flange it, custom downpipe, injectors, walbro pump, "piggy back" msd ign. intercooler, piping, an whatever youll need. Take your time as i am doing the same.

I have an idea for all us turbo geeks, 1 maybe 2 years from now we come back to this thread and post our builds.. That should be plenty time for those that dont have the cash and or time.. As for me ill hope to have dyno runs and flow charts available so you can see a proper full range setup. Sound good?

PLease i wanna see this with the Benz turbo... Also if you can when you can could you provide a flow chart?? with what turbo would be the best one to use. I agree with GeeoDee Hybrid will be the best way to go.

You may have to build an efficient manifold.

[QUOTE=Gee oh Dee;745639]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.[/QUOTE]

Sorry, I'm just posting all the information I can so its available. You don't have to read it. You can block all my posts if you like.

Stop being immature? I'm being honest, and giving fact. Go ahead, ignore fact and advice given to you by someone who obviously knows more about turbos than you.

And isn't it cute, I say I've been doing research for quite some time about making the Jeep 4.0 a Jeep 4.0T.

So go ahead, make yourself look even worse by pointing out that I "think an XJ can't be turbo'd" when clearly I am working to make it possible.

Here is the problem I see with your thought. Yes, you would indeed need a "smaller" turbo, but those are turbos off a 2.0 4 cylinder. You will over run the "hotside" or the side of the turbo that is moved by exhaust gas. This can and will cause some serious issues. Some being a bottle neck in your exhaust. It just won't let enough exhaust gas through to be effecient. It'll be like plugging your exhaust. Not good.

Or you'll just overrun your wastegate. The exhaust will chose the path of least resistance, and that'll be to keep spinning the turbo. You will lose all control of boost, and you'll have "boost creep". You'll end up nuking the motor quite fast.


Pretty small? How do you know its not too small? Again, whats the technical information from this turbo you have? You've got all these "skillz" so why not provide the information?

I'm not the only one calling you out on this, just look at Abaddon's post. He's asking for the information, too.

88Cherokee4x4, see, I'm not the only one being a "dick" and saying "negative things." We just wanna know the easiest information possible, and you aren't providing it.

My guess is that you have been trying to get your highschool shop teacher to tell you what you've got and he has no clue. So you are now asking area shops to tell you what you've got so you can come back here and "show us all up."

Good luck.

Heh, never said it wouldn't work. I told you from my first post you need a different setup with a different turbo.

Thank you very much, sir!

It wouldnt' be that hard. Just use the surface that mates to the head, use that as a template and move from there. Just make sure all your runners are equal length. It'll take time, and you gotta be good with a welder, but it can be done.

So you never get water under your hood? Never have any splashes anywhere? Interesting. Guess that video on youtube of that guy with the TURBO DIESEL suzuki samuri that goes in up to his hood is just plain screwed, huh?

Should I post a link to that video?

How many ppl have ripped out their Tcases? How about fuel and brake lines?

I don't understand how some of these people can believe what they blindly believe.

Somehow it seems like common sense to me, but I guess common sense isn't really all that common.

Wow. Big honkin' argument over turbos, eh?

Just my opinion...but I'd forget about turbos and put a big block chevy in there...it would be easier.

Seriously, what is this all about - more power? In an XJ??

What for? It's a 3000 pound SUV grocery getter and flexmobile. What do you need horsepower for? I think the same thing every time I see a CJ5 with a SBC stroker and headers. WTHeck are you gonna do with 400 horsepower in a CJ?

You want performance for very little money and dead-bang reliability?

Gears.

Thats why I've got 4.11s.

I agree with you on most points, but also keep in mind I've had this setup in mind for a TJ Wrangler, not the same as a unibody XJ. I'm also looking to spin rubber bigger than 38s, so gears will only get me so far. A V8 swap would be nice, but turning 38s will suck enough gas, so I'm wanting a more balanced rig. And we've also got an automatic, so that makes a HUGE difference in drivabililty when it comes to a turbo'd off-road wheeler, whether its rocks or just plain mud.

This is why im looking for more. . Theres very few fast xjs. And plus mine is 2wd so what can i do. I live in Miami Beach, what can i do?? And its fun doing this around wheelers.

Its not cheap, you get what you pay for, if its cheap then it wont last very long.

Submerge yourself into this video, pal.

I dunno where he has his turbo, but I'm guessing its under water.

Should I PM you this link to make sure you get it??

this looks like the most simple and cheapest setup. 505 Performance kit.



This is kind of like a remote turbo install but its still in the engine bay. In a way this is how subarus have their manifolds setup with an up-pipe.
