I'm waiting for one compatible with a 2003. I think the Banks is only good for 2004-2006. They are working on one for earlier TJs though. When it is out, I'm getting it. I haven't seen one on a jeep but on Ford and GM diesels they are awesome.

Fair enough- I've only seen stuff on YouTube but so far seems good. My only concern so far is my move to Arizona. Summers there are way HOT! I don't know how that turbo will do in that heat.

Banks did a lot of stuff with military trucks in the desert (Iraq, Kuwait). That is real heat. The trucks did will there and Banks has a lot of testing in serious heat. I would bet they would be fine. They do 6psi and that doesn't heat the air that much but an intercooler would probably be a good idea.

True but I don't think the banks kit has an intercooler, I wouldn't know where I could put one lol

Waiting patiently till I'm out of school. By then I'll likely need to freshen it up/rebuild so might as well tack it on. Really no downsides to it? Spools up quick, solid boost in power, still the 4.0. Just gotta see how it holds up in the long run

All builds I've seen with a turbo, diesel or gas, have on in front of the radiator.

Jp mag did a project write up on a tj turbo kit

You sure about the year break

03 and 04 are almost identical but 05 06 are very different from prior years so a 03 to 04 break does not make much sense to me

You are correct. It is 05-06.

You can do a STS remote mounted turbo.
Guy around our town has one on.
He mounted his on the right side of the Jeep where the Jeep logo is his is a 01 I think it's a 01 or 02 can't remember...anyway he mounted it out side the rig and the exhaust exited up along the front fender like a military WWII rig. He said it gave him about 70 more hp. He said he didn't need any inter cooler or turbo time due to the location that it didn't generate as much heat as a static manifold mount kit. He of course had the engine rebuilt as he was adding the turbo kit but he didn't go crazy with up grades on the internals he kept it as close to stock as possible besides the fuel injectors and fuel pump. which he said he didn't really need to do. He said no CPU re flashing needed. He said the turbo pipping was the hardest part of the project. He was a hunter so the rig was used on mostly hunting trails so it wasn't heavy rock climbing so the extra plumbing wasn't an issue. It was lifted about 6" with 35"s on it. He said the turbo helped keep the power up in top end and really added grunt to low end. So call the guys at STS Turbo systems I think you will find the info and answer to your project wants and needs.

Have you thought of a supercharger instead. They have real power, I've driven one. Heck, spun the tires. I'm going to put one in next year.

There's a thread circulating around on a guy who did one. Or look for any thread Giant Panda or Red Panda ( I forget his name ) makes. Dude goes a lot of conversions and add ons.

As opposed to what? Fake power? The turbo has a nice whine itself. The biggest benefit of this system is that aside from welding the oil pick up tube to the pan, it's totally bolt on.

I think his comment was pointed towards the actual mechanics of the turbocharger as opposed to the supercharger. Correct me if i'm wrong but superchargers are belt driven while turbo charges use exhaust gas or something to that effect?

I did it. Took me about 2.5 days to install due to various setbacks like stuck bolts and whatnot.

As for power: the trans no longer downshifts to maintain speed going on overpasses. Around town I don't see any boost at all. I think it needs tweaking as it arrived with a damaged wastegate actuator and I had to set and install a new one. The most I've seen is 5 psi of boost.

All the noise I'm hearing is suction from the intake, the turbo itself is very quiet.

Haven't happened to dyno it have ya? Seeing their test it looks like it doesn't spool up till 2k rpm, so not noticing it around town makes sense.

I don't even know if there is a dyno in my area.

I got it sorted out though, wastegate actuator arm was too long. Shortened it by 2 full turns and now I'm making about 2.5 at 65 and constant throttle and a full 7 at wot.

Also, I can get some boost in town if I get in on it a bit.

One more thing:

I just did a quick mpg check and I got 12.4, up from a pathetic 10.whatever.

I only did about 45 miles so far and a lot of it was testing the boost.

I'll report back after I go through a whole tank.

I'll update more in the coming days. Tomorrow I'll have a chance to put some miles on it.

Our family friend put a turbo on his tj about 7 years ago before any kits existed. He had to do tons of work to get it to fit but he still runs it to this day. I don't know how much power it added but he classifies it as one of the most useless mods he has done. I'm sure technology has changed and turbos are much more efficient now.

Personally I would do an engine swap long before I put a turbo in a vehicle that gets covered in mud, goes through deep water, and breathes in dust filled air.

The fact that I can maintain speed on the highway and not slow to a crawl on overpasses makes this mod far from "useless".

And that's just the beginning...

I'm not worried about mud, deep water, or dust-filled air. It's not like the banks turbo is the first turbo to hit the market. Many trucks and cars that see the same mud, deep water, and dust-filled air are equipped with turbos and don't have problems.

I'm sure your system works well and that's why I mentioned that I'm sure technology has changed since he had his installed years ago. I know it gave him more power and he enjoys that but he had to do a lot of other custom fab work to get his system working and it just wasn't worth it.
