Question: 180HP turbo vs GT

[quicksilverdon]

Didn't mean to kick a hornet's nest!
From what I knew, GT & the "lite" engines were the same, didn't know about injector difference '03- '04.
I also believe the autos are the same - except for the autostick feature available on GT only.
If I read everything right, a GT on regular gas = turbo lite, no need to change engine controller since knock sensor will step in? ? [:I]

knock sensor to a point, it is for light spark knock only. id be cautious about running regular, might have to drive with tail between legs. IMO use premium and enjoy the power, its worth the extra $ at least to me

As long as you drive extremely conservatively, you could probably get by with running regular in the HO all the time, but as has been mentioned, there is a limit to how much the PCM can cut back performance to avoid engine damage. Even the manual provides warnings in that regard.

For non-aggressive driving you can probably get by with mid-grade gasoline. For aggressive driving, always use Premium.

No hornet's nest kicked at all, just trying to clarify some things as lots of people get misinformation fed to them, or else they mix up the information in their heads....happens to everybody sometimes!

But the "GT on regular gas = turbo lite" isn't quite right either. While we all agree that running a GT on regular gas will negatively impact performance, I just can't imagine that it will rob you of 40HP! No, the Lite PCM is indeed programmed differently from the GT, but it's more than just allowing you to run on regular. The price you pay for cheaper gas is lower HP, and that logically means lower boost levels.

That is bunk...the two engine are the same....the 220HP is not a SPECIAL this and that. It shares the same stuff as the 180 lite...Alos premium a few cents more....Where do you live? Here in Louisville premium is about 20 to 30 cents more per gallon than regular.

If you think the 180 Hp shares the same bottom end parts go to your Chrysler dealer and find out if the part # are the same for both engines. I was told by a dealer that they had 2 different bottom ends.

I did a parts search online from moparparts and the part numbers are the same...IE crank/cam/rods/pistons....

Typical. Your dealer doesn't know squat. [:I]

Just to chime in...I really think it sucks that you can not buy a turbo lite (ie. Touring Edition) with a 5 speed. Only with the GT can you get a turbo and a stick...from the factory! What is Hahn's number again?

You know, I seem to recall an article regarding the 180 hp turbo that made some mention of it not including the piston cooling jets found on the high output version ...

I'm not saying you're wrong (because I don't know with 100% certainty either), but this just doesn't make sense to me. Understandably the 2.4L is beefed up for the turbo version compared to the N/A version, but why do something different that would cost money when the PCM is the only difference between the Lite and HO? You'd need another assembly variation, and I just don't see DCX doing it.
