Turbo from another car?
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
And I answered his question very simply.
No. You cannot grab any turbo, slap it on, and make it work.
Putting all the under hood BS aside, not one persons has addressed the need for more fuel.
You buying everyone new motors if they turbo the thing and it grenades? If so, I will Turbo mine TONIGHT. Have a brand new turbo sitting in my basement.

However, my comment wasn't directed at the OP as much as it was in response to your other comment.
You stated the key, multi stage or hybrid turbos. Again, with the right setup a turbo XJ would be quite possible and very trail capable.

Which is why I gave my simplest answer, 'no.' You cannot just use any turbo.

Address fuel needs. Address incoming air needs. Fab up the piping. Get colder range spark plugs. Buy gauges.
And probably a dozen or more little things I neglect to mention.
My memory isn't the best. That why everything is written down or emailed.

You can't just slap a turbo on anything and call it a day.
I work for Subaru, and have owned a few turbo'd Subarus.
A Turbo is now adding compressed air at a higher rate then your engines vacuum was. You need to be able to match the air with the CORRECT fuel. 5 PSI is a lot if you think that your low end has never really seen positive pressure. Stock pistons in most cases are not built with stand that much pressure and detonation. You will destroy them. Your head gaskets may/may not be able with stand that pressure.
Like someone said, "what have you got to lose? Your motor" That is correct.
Good Luck though

The stock bottom end of the 4.0 is pretty stout. Given its in good condition and not abused it should be able to easily handle 5psi, with supporting mods.
I used to own a 93 GSX running 30+ psi. Ran about 500whp on 93the octane.

I've never owned a turbo but worked on/tuned enough to know what's going on there.
A buddy of mine back in the day had a Buick Grand National with a single T72 that was making about 800HP at 26PSI. Second fastest car I have ever driven . . .

well aside from what everyone else is saying, i don't see it being free. just because even if you get everything for free, and installed for free you will still need to have it tuned.
getting it tuned will not exactly be cheap.

Anyone who thinks turbo are only for too end power are just wrong. Wheeling with a turbo is great, it just has to be sized properly. The turbo that I used on my brothers Toyota, will make 5 lbs of boost at as low as 2200, and will start to make boost around 1800 rpm.
And as long as your not wide open its not just gonna shoot up and start
To make a ton of power. It doesn't work that way.
Turboing is easy, well a manifold might not be, but its the fuel system that gets tricky. You need a proper way to monitor it. I.e. wideband. Unless you plan to do that or dyno tune it don't bother, you will just end up blowing it up.
Don't forget you have to plumb oil to it also and will have to remove your oil pan.
Low boost and no intercooler is ok but you need low timing and good fuel.
Oh and what does a cowl hood have to do with an intercooler?
