Increasing power from my TJ

Yes, I have already reduced the size, but I thought that an additional control unit could improve the delivery, just a few more hp
Take the top and doors off, remove back seat. Get minimum weight would help some. (4.0L sticker on side ??)
Homologation is the process of official approval or certification that a product, system, or vehicle meets a specific set of standards. This is a formal process, often by a government body, court, or sports authority, that confirms something is acceptable for a particular purpose, whether that's to be sold in a market or to compete in a race.

In Italy, if the engine numbers do not match the registration document, no insurance company will issue you a policy and without it, the fine you risk is the seizure of the car (you lose it permanently). For the rest, I think I will opt for a turbo kit at this point.
Your options on a 2.4 are about nothing. Regearing is the closest thing you can do, although the 2.4 (using the PT Cruiser/Neon setups) has been turbocharged in the past by people with VERY good fabrication skills. A turbo is probably a bit over your head.
Yes, they are stickers put there by the previous owner, in fact they are not in the profile photo because I removed them
The good news is that it appears to be pre-wired for cruise control.
Lots of room for a turbo and intercooler. I actually knew nothing about this engine but in reading about it, it’s a pretty modern, double overhead cam, four valve, crossflow head. Although only 150 hp in its TJ naturally aspirated form, the 2005 Neon SRT made 234 horsepower and 250 foot pounds. A quick look at the Internet shows a bunch of people have done turbos for it. And I’m sure the neon numbers can be improved upon with little work. All that and you keep your same engine block number.
I hope to find a kit here in Italy, but above all that they are able to assemble it
Off and on I've been looking for a nice cheap 2.4l tj and turbo neon or pt cruiser to combine. Should be possible for around 7500$ or less and make a fun stockish cruiser!
Unfortunately I don't think there is a ton of knowledge about the 2.4L here. It wasn't the most popular at the time and not as many were in enthusiasts hands.
The 2.4L is used in a bunch of Chrysler vehicles from the late 90s through early 2010s I think. I believe the block in the TJ is cast unique to the TJ, so you probably can't just swap a Neon SRT motor into it. However the pistons, rods, heads, intakes - I think these are all the same dimensions at least throughout. You could probably poke around looking for Neon SRT or PT Cruiser GT info to figure out if they came from the factory with different rods/pistons from the regular 2.4L. This motor doesn't have much of a following. You'll need HP Tuners to setup the PCM for the turbo. You might be able to find a stock Neon SRT of PT Cruiser GT tune on HPTuners Dodge-Gas forum of you ask around to help as a guide. You'll also need to procure a MAP sensor for one of those - not difficult to find.
I think one way to think about this motor - it's 60% of the displacement of the I-6 4.0L but puts out 78% of the peak horsepower - stock. And the fuel economy was 16% better. That's not bad things and 4.0L was well past it's prime era. Unforunately the poor aero of the TJ consumes alot of ponies. There was also Mopar support to take the Neon SRT-4 to 310hp. In 2006 people didn't think you could do that and get any reliability but they were fine and have made much more.

Interesting discussion. The 2.0T JLs perform OK given their weight. I’d love to see someone here show us what a turbo 2.4 can do in a TJ.
Cold air intake is never recommended for a 4.0, and presumably never for any TJ. The caveat is when necessary due to highline fenders.
Again, CAI is never a bad thing. What is bad is calling a HAI a CAI when it isn't. That's where the disdain comes from.
Excuse my ignorance, which intake kit are you talking about?
