Why not build a 4.7L stroker? Mine runs awsome. I bored out my 4.0l HO block .40 over. Installed a crank and rods from a 258. Added some Ford 19# injectors and a cam and it get s better fuel milage then my old 4.0L more power and torque. You can buy prebuilt ones for $3000 or so.

what I find amusing about the add for the "new" tornado, is it claims to create a vortex thus making the air denser! Lol
a vortex swirls the air! thus creating better atomization of fuel!
it dont make it denser!

Sounds about right. I know when I supercharged my F150, the kit was around $3500. You could definitely feel the "seat of your pants" difference when it was in though!

Just the block, head and internals. No valve cover, oil pan, no fly wheel/clutch or any add ons like water pump, alt, ect.

I'm trying to avoid an engine swap because my pockets aren't that deep haha. So I think I will just do the little things that increase the performance.

But the fuel injected engine needs to know it's operating under boost and be able to deliver the added fuel to match the increased air (so their claim of improved fuel economy is bogus as well), or it would just run lean and burn up.

Personally, I wouldn't want huge Hp in the Jeep because it would make it much easier to break driveline parts. The 2.5 still has plenty of power in 4WL, and in 2WH it goes 65mph. These things are terrifying about 65mph anyway Save your money.

I don't care about the high speeds. Jeep + high speeds = roll over waiting to happen. I just want more horse power and torque. So when I get a lift and bigger tires I can still make them spin in the mud and stuff. But thanks for all the information.

If you are happy with the power you have now, you can have the same perceived power by re-gearing the axles to match your chosen tires size. This isn't cheap either, but you have a better shot of matching power with a 20% gear reduction than finding 20% more power in a normally aspirated engine.

Just my 0.02

That's what my buddy was saying. Just change the gears to get more low end torque.

The only power reduction I have noticed is uphill in 5th gear I can't hold 60 mph. Other than that plenty of torque off road and stoplight to stoplight. Unless you need V-8 power go for some new gears and it will be great.

What rpm are you running at 75 mph? Would think it is quite high with 4.88 and 33's.
