It will still have to pass emissions which it won't do without all of the Tier IV horse shit, and computers to control it.Solution find a wrecked 2.8l duramax chevy colorado take engine rebagde engine with vk stamps and cummins logos since the duramax 2.8 is almost identical to jeeps 2.8

Why wouldnt it pass emissions if the egr and def system are kept intact? I dont think you can get these newer engines to run without the ecu, bcm etc. I admit i know absolutely nothing about what hoops you have to jump through in california.It will still have to pass emissions which it won't do without all of the Tier IV horse shit, and computers to control it.

EGR, Def, particulate filters, and all the assorted sensory receptors and computers associated with them are all part of the Tier IV emissions standards and absolutely,accross the board unilaterally suck nuts.Why wouldnt it pass emissions if the egr and def system are kept intact?

Is it possible to just swap whatever engine out for the original everytime you need inspection sure it would be a pain but they wouldnt know would they?
Yes. That is how it is. And yes, I know some of those guys swap their engines back and forth every two years. That is just one more cost to the price of their toys. Others simply are "green tag" vehicles, which means they never see pavement.Is it like that if you want to build a rock crawler or sand rail? What if your building a kit car like a caterham 7? Also all the guys running around socal in pre runner trophy trucks what do they do because i know there are swaps happening ford rangers dont just come with 600hp from factory and if you can get that much out of a stock 3.0 vulcan engine your a bad mofo.

This is how its done. Doner vehicle. You have to show what it came out of, it must be same year or newer and will meet emissions for whatever it came out of. My last swap was an 04 4.3 and 4l60E out of an Astro van into a 1984 Toyota Pu. We did a stand alone harness for the engine and trans. The vehicle is now smogged as an 04 Astro. We had to graft the Astro vent hoses and fuel pump module into the factory tank. He needed the same number of cats, close to the same distance from the engine as stock.It will still have to pass emissions which it won't do without all of the Tier IV horse shit, and computers to control it.
Now you can understand the growing popularity of adult coloring books and safe spaces.I cant even imagine living there. That would be hell to me.

I am looking at gasser options for sure at this point. Another offered the idea of the Chevy E-rod series CARB legal engine. My only issue with that one is the size...I really don't want a 6.0L engine in my Jeep...I'd have to pull a trailer with a fuel cell just to get anywhere! LOL. A friend suggested I call Turn-key in Oceanside to see that they can do. I'd rather buy a "package" and do the install myself. I am a novice mechanic but I am surrounded by buddies who know a lot about that stuff...it would be fun and rewarding to do this.You might ask these guys

They do California carb legal hemi swaps and such and may know about how to deal with all of this.
You also may ask how it would be if you swap to one of the European diesels that were available from stock in the jk wrangler.

definitely going to check them out. My Jeep will be back on the road come hell or high water! I've owned it since new...almost 30 years...no F-ing way is Kali taking this off the street (offroad)I fully understand your point, I wouldn't want such a heavy thing in a YJ.
I only thought that guys like them no how to work with the officials and may help you out.

if it wasn't made for america, you cant put it in unless its a pre OBD2 (Diesel only). I would love to put the Australian diesel in my cruiser but im OBD2.You also may ask how it would be if you swap to one of the European diesels that were available from stock in the jk wrangler.

I don't know some of specific regulations, sorry.if it wasn't made for america, you cant put it in unless its a pre OBD2 (Diesel only). I would love to put the Australian diesel in my cruiser but im OBD2.

^^^This is how I've helped get LS1-swapped RX-7s legal. You need every emissions or emissions-related system from the donor vehicle to be swapped into your vehicle and fully functioning. Then it goes to the BAR and eventually gets an official sticker that shows it smogs as whatever the donor vehicle was (for example, the '93 RX-7 I helped BAR smogs as a '02 Camaro).This is how its done. Doner vehicle. You have to show what it came out of, it must be same year or newer and will meet emissions for whatever it came out of. My last swap was an 04 4.3 and 4l60E out of an Astro van into a 1984 Toyota Pu. We did a stand alone harness for the engine and trans. The vehicle is now smogged as an 04 Astro. We had to graft the Astro vent hoses and fuel pump module into the factory tank. He needed the same number of cats, close to the same distance from the engine as stock.
One of my buddies swapped a newer LS motor into his 05 TJ. I don't remember what the doner was but, the referee made him duplicate the dual fuel tanks. I don't think it was out of a Vett but the set up was similar. After he got his new emissions label he swapped back to a single tank. Some of the regulations are vague and left up to the interpretation of the referee. There was no real reason to demand dual tanks.
Bottom line is, CA doesn't care if you do a swap as long as it meets their criteria. You only have to have the proper emissions. You don't on the other hand have to have ABS, body control.. For the simplicity thats why I like GM. The computers are easy to program without having to add in a computer to lie to the PCM. You just turn on or off what is needed.
When Cummins posted a 50 state motor, I got excited. The problem is though, people think you would just drop the motor and go. You still have to have the proper exhaust and intake. I'm not sure what you would do there. CA changed the regulations on intake and exhaust modifications not long ago and that may be what halted its certification. If they offer a 2.8 in the Colorado, that would be easier but, your smogging as a Colorado.
Now, for me, I'm done doing swaps. If I want more power or a different fuel, I just go buy what I need. My buddies 4.3 Toyota had a weird issue. It was randomly popping up a crank sensor code. Because its a swap, no shop will touch it. They don't have specs or diagnostics for a "Chevota". The issue was so random I couldn't pin it down. Everything on the crank sensor circuit was perfect. When we did the swap, I demanded only GM sensor's. I sent the pcm out and had the crank sensor circuit taken out completely. Computer doesn't care about it any more. Code came back a month later. Turned out, he decided he wanted a new distributor. He bought an Auto Zone unit and the module in it was flipping out the PCM.
As a tech when your looking at a swapped vehicle you have to decide how much time you want to spend on something your pretty much guessing on. There are so many ways just an improper routed harness can pick up interference from other items or wires confusing the computer. Next add in an improper software package and cheap Chinese parts. How many techs out there know how to properly use a lab scope and also know what the sensor patterns are suppose to look like. That leaves software and you cant look at that easily.
8-10 thousand dollars later (or more) you have a Frankenstein that very few people will touch if it has an issue.

The vast amounts of public access land to explore, wheel, and camp on almost made me and the wifey decide to stay there, even with the ridiculous firearms and other laws. It has it's perks but the cost of living pretty much ruled that out for us.I cant even imagine living there. That would be hell to me.
