    Don't really want to rain on your parade, but that's not a workable plan. Yes, you can probably figure out a way to put it on there. However, that turbo was mated to an engine over twice the size of your 2.5, meaning it won't blow enough exhaust to spool it up. And even if it could, the factory fuel injection cannot supply enough fuel to match that amount of air. If you really want to do something like this, you'll be money/time/effort ahead going with an Avenger supercharger. It would also perform much better than a cobbled-up turbo system. HTH

    2x on Avenger supercharger, or putting in time/effort/money into a QUALITY setup. FI is not something to half A$$, unless your YJ is just a project rig.

    Also, it's a matter of debate as to whether either a supercharger or turbocharger is gonna get you power in the low to medium power range...normally, those are intended to get you power up higher when they spool up...All in all, this is a BAD plan...

    look into the smaller mitsubishi eclipse/eagle talon turbo's. they'd be better suited

    I'd agree on the supercharger. Turbos require revvs to spool the compressor, a supercharger will build boost from idle, much better for offroading. And as mrclean mentioned, your lil 2.5 wont get that turbo to spool at low RPMs, youll be spinning your engine at 4k to make power.
    If a turbo is what you want, get something smaller that will spool quickly at around 2k RPM. IHI makes decent small turbos.

    your gonna spend more in $$ and headaches trying to make that work, even if the turbo is free, getting it mounted is only the first obsticle, then you have to figure out how to make your fi work, being your intake manifold will now have a + pressure rather than a - pressure it was designed for, all your vacuum powered things will either not work or not work correctly

    with enough determination time and $$$ im sure it could be done, but after all that would it really be much more work to just do an engine transplant?

    i tried to get it to spool by make a tube that ran from
    the end of the exhuast to the turbo
    and it work
    but with the engines rpm at 5000 the turbo was turning at 500 rpm at best
    so turbo is way to big
    i dont think the catback or muffler would have cut back the exhuast flow that much

    so want to trade or sell me your turbo

    Y'know, 2.5's are kinda known for blowing their rods through the side of the block without a turbo adding boost... not to mention spinning bearings...
