Could take the engine block and some other misc pieces, I'm sure. But the whole thing wouldn't bolt up and you'd still need to fab up some stuff.

Plus, again. He has the 2.5L, so I'm not sure if that would be the same thing.

I suppose...but you might as well build a TPI 350 Chevy, it would be cheaper and provide more power. To swap to a 2.4L from a 2.5L in a TJ, you'd need an entire 2.4L system: engine, accessories, mounts, transmission, computer, wiring harness, everything. Then you'd need the turbo equipment from the PT Cruiser, and you'd have to follow the thread posted here someplace outlining putting the PT Turbo on a Jeep 2.4L. The person doing that swap determined its was easier to swap the PT Turbo to the Jeep than to swap the entire PT engine to the Jeep.

it would be a LOT of money and work to get what you could have a lot easier and cheaper with a 4.0L or stroker 4.7L swap. you'd have more power with a V8 or stroker 4.7L than with a turbo 2.4L.

Dont normaly get involved in this stuff, but as I have experience with Dyna jet Dynos, I have to say that this is a really silly statement.

You don't need to be running a 1/4 mile race to get great benefit from using a dyno to tune your engine

Don't be a tool, use one!

Exactly.

MPG, power, etc. everything relies on your tune.

That'd be like going to the bathroom and not whiping your ***, then saying, "Hey, I got pants covering anyways!"

Isn't the SRT-4 turbo an EvoIII 16g? I'm looking at putting one of those on my Suby, it's a fantastic turbo. I don't know if the PT Cruiser uses that too, I imagine it should. Either way, hilarious thread, keep fighting.

I believe all the internals are interchanbgeable on the 2.4, as well as the head, BUT the blocks are different. I started a thread on this exact thing earlier, just bench racing, but it gets you thinking.

Nah, I believe it's smaller. Evo III 16G, is exactly that... a 16G from a Mitsubishi Lancer Evolution Generation 3.

The SRT-4 uses a TD04H I believe that is either a 14B or somewhere on par with it.

I know what an EvoIII 16G is, but I also know it's a very popular turbo. I swear someone told me that's what Dodge used, but a quick search says otherwise. Anyway, you're right, it's a TD04, a TD04LR-16Gk according to wikipedia.

Probably a variant then, lol. Both of us had some numbers that were correct.

Mitsubishi makes about a million TD04 variants, I have one on my Suby, I encounter multiple on diesel engines, it's a very popular OEM turbo that comes in many shapes and sizes.

The PT is a transverse engine. The exhaust manifold will bolt directly to a TJ, but the turbo will not fit, due to it hitting the firewall. Air Sierra had an adapter machined to flip the manifold upside down so the turbo mounts in the front. The turbo must be re pinned so it oils correctly. The stock ECU is good for about 12psi of boost. The stock injectors will handle 3-4psi quite nicely. Air Sierra has part #'s for bigger injectors to handle more boost. He has around 20k miles without any issues. My turbo build starts as soon as I finish installing my new plow on my Dodge. I have right around a grand invested in parts for this mod.

At that boost pressure, you might as well be pissing into the wind. I wouldn't waste my time for a gain of maybe 30-40hp and a can of worms.

I would disagree that a mod that nets around 225hp and 245lb/ft of torque and over 20 mpg in a Jeep is "pissing in the wind" and a waste of time. However, things are supposed to be bigger in TX, so I guess 4 bangers are frowned upon. Maybe some research on this mod would change your impression, but maybe not.

Air sierra did this exact mod to his 2.4l I think it was, and he had to do minor fabrications for this turbo to work. He sees an imporvement in overall power and an increase in mpg to 20. just some facts

That is correct. I have spoken with him on numerous occasions about this build. He is seeing about 22mpg on 37's with 5:13 gears. 20K miles, no problems and he seems pleased with the performance gains.
