Turbo from another car?
Im doin a project at my school and i can have a turbo put on for free. Now my cold air intake was ment for a civic and all i had to do is cut some of the pipe. Could i get any turbo and just get some custom tube to run to the trottle body? Id only run it at like 5psi so i dont think id need an intercooler especially if i get a cowl hood while doin it
I just dont know anything really about em

LOL @ cold air intake on a Jeep - watch them puddles.
Intercoolers have nothing to do with boost level - they have everything to do with air charge temps.
I still haven't figured out why anyone would want to turbo a vehicle that is wheeled - but that may answer my question right there in this case.

I would say do it. Then if you don't like it you can take it off. What do you have to loose? Also why cant you run a snorkel with a turbo?

sounds logical enough... take the air from inside the cab to prevent as much contamination as possible.
if we all built the same rig wheeling would be lame.

Good - if it isn't outside of the engine compartment it isn't a "cold air intake" because the air under the hood is anything but.
Hopefully your "shield" is sealed.
Wheeling is mostly spent utilizing low end torque. Turbos develop higher-end horsepower.
Imagine crawling up over a rock at 1500-2000RPM and your turbo spools up and instantly spins you to 3500+RPM . . .

I know the turbo is for more high rpm power, but again, itd be free so why not if itll fit. Help in the dirt track races too

Would I do it? No, but it's his jeep, let him do what he wants to it.
If it's free do it. Or just take it and sell it for some jeep money!

Turbo it!!! Just think about what makes a diesel powerful: the turbo, and diesels make their power down low.

lol everyone is giving their opinion on wether he should do it or not and not actually answering his question. IMHO i would check out 2gstratus.org and look in their forced induction part of the forum. they turbo 2.4s and alot of those guys a really knowledgeable in FI. and you can tell em "xmoparx" sent you

It is the ridiculous compression and subsequent thermal efficiency of such a high ratio that develop the massive low-end grunt (And makes the diesel so powerful).
The turbo helps but not every diesel has one - and a turbo on a diesel isn't subject to the same lag issues as one on a gas engine because in order to keep the gas engine from self-destructung at boost levels the compression ratio is very low - basically rendering the engine nothing more than a means to spool up the turbo at low RPMs. Diesels make low end torque so the lag isn't anywhere near as noticeable.
The reason so many diesels have turbos is because there is no limit to how much boost they can run like there is with a gasoline engine.

Do what you want. it's your car.
now if it was mine and I had the time/money I would put a SMALL turbo and an inter cooler.
Why? Cause a smaller turbo will spin at a lower rpm. if you get a big turbo it wont kick on till ~2200 rpm, but with a tiny one from a VW 1.8t engine on an i6, it will kick on around 1300rpm witch is almost idle rpm in drive.
oh and I don't go threw puddles or rocks. I ride sand.
I always wanted to put a supercharger on one, but I can't afford a kit and I don't want to lose power steering or A/C. Maybe i'll run dbl electric fans and move some stuff around. :\ dreaming.

Sounds like you know a little bit about a turbo car.
However, if the setup was done correctly, it would be amazing, and would have a beautifully linear power band. All these guys slapping on random turbos will get the result your discussing, that sudden boost hit.
But, again, if you really know what your doing and you take the time to do it right, it can be done on a 4.0 Jeep motor with great results.
