I stand by what I said. If I had the money (and only in a Jeep originally equipped with a 4.0) I'd do the stroker long block. Period.
BurlySoldier is right. Truer words were never spoken. There is no substitute for cubic inches.

Tell that to this 3 rotor turbo Rotary..

You could pick that up and throw it in the back of your truck. Cubic inches are for cavemen

Which costs less to manufacture?

Which costs less to repair?

Which has a longer expected service life?

Which requires less regular maintenance?

And, since this is obviously being wasted on a hater, I would mention that IJM would not even be here if it were not for cavemen.

All in fun lol, just showing the point that little tiny rotarys can make nasty amounts of power. I appreciate the caveman, but weve all gotten better from that time! Lol.

Good god. Seriously. You are here in a Jeep forum Internet argument of turbo vs displacement and it's application in a Jeep and you show up with a piece of crap rotary engine? Was that serious or did I miss the joke?

There is no replacement for displacement accept valves, compression, dual cams, and power adders.

Let's not forget that back in the 60's big blocks with massive displacement were turning out tiny amounts of power on a hp/cubic inch basis.

The Japanese just about did the big three under in the late 70s and 80s with small engines, lots if valves, twin balanced shafts, and compression.

BMW is even putting a 4 banger in their coveted 3 series.

Will we see Jeep launch a 4 banger turbo wrangler? Maybe not, but at 7 bucks a gallon, that arrangement has a lot of appeal and who knows what might be in the future.

The wankel engine is a engineering masterpiece.

Such a new way for the combustion engine to work, its a shame no one put more time and R&D into the motors. Id rotor my TJ.

Figured I would throw in my opinion on this one since I have been playing around with this the past year. The owner of a local performance company came by while I was visiting a friend and we had the hood up, he said looks good, but it would look a lot better with a supercharger on it. I jokingly said " lets do it ". To make a long story short after months of design work and trial and error, supercharger was in and ready for tuning : This is where the hard part comes in. We tried serveral different fuel managment systems and several different tuners. I found out it is very easy to make Good HP numbers on the dyno, but it is another to have good driveability and not have a check engine light on. Another problem is that I mostly wheel in the sand and do rock crawling trails, I wanted my power to be right off idle. Well we finaly found the right blower and crank pulley combo to spin up the blower fast, and the right fuel managment and tuner to make it drive like factory, untill you get on it. All i'm saying is that before you go trying to do this, do your research. Here is a link to my Jeep making a dyno pull when I was finally happy with the tune. On The Dyno: Supercharged Jeep Wrangler - Portland Speed Industries The company that helped me is Mangnum powers, He is currently having all the cnc parts cast and will probably be selling parts/kits soon.

Small block chevy. I could probably build one for cheaper than those turbos or the stroker kits. If I'm pulling that 4.0 out, its not going back in.

Small block chevy is a good option, I have a friend that did that swap, thing runs great! Unfortunatly now he only gets to drive it on wheelin trips and has to be trailered wherever he goes because he can't get tags for it. He failed to check his local DEQ requirements before doing the swap. If you live outside Emissions it is a great choice.

Diesel engines like those in Deuces require Turbochargers just for it to combust the damn fuel correctly.
When the turbo goes... It stalls... All... The time.

AGREED! When installed correctly, a turbo on a Jeep can absolutely work. Takes patience, time, MONEY, and lots of research!

A diesel without a turbo is really close to worthless. Does the OP have a 4.0? They run pretty well stock. Horsepower is relative to how deep your wallet is and there is always a tradeoff somewhere.

not true. They do great in workhorse platforms...tractors, generators, welders, etc.

I think the 4.0 needs some more power. It makes me nervous to pull out into busy traffic, because it so slow! If the turbo was set up right it would be perfect. With a turbo the 4.0 wouldn't fall on its face after 2500rpms. I drove a Turbo Subaru Forester before the jeep, so I am use to having a good amount of power.
I have a 05 LJ Rubicon with a 6spd. I seriously thinking about doing a 5.3 LS swap!
