Engine Diff (3.5 vs 3.5 H.O.)

Subject says it all? What's the difference between the 3.5 and the 3.5 H.O. engine? Bore x Stroke and Compression are the same. So where do all those extra horses come from?

How simple would it be to make the proper modifications to bring our '04 up to the H.O. version?

Addition of a manifold tuning valve, retuning of the PCM, and you're set.

Maybe it's the rating . . . not the hardware?

It's funny how often this comes up....

I really need to get back to work on this mod..... The really hard part of this mod is getting a dealership to do the programing for you. Some say it can't be done.... (these are the idots) others say they are not sure how to do it but will try but at $75/hour.

And of course this keeps getting put off since I keep buying other toys..... EVIC+ and 300m special mirros!

What programming needs to be done (basically, what needs to be changed?). A friend of mine has the dealership computer that hooks up to the car. He'll even let me play with the damn thing (that way, if something gets screwed up, it's my fault, not his. Therefor, I'm liable, not him)

Wow you could become my new best friend.... how far are you from Detroit.....


Anyhow.... This is what you need.
1. High output upper intake manifold.
2. you need to add 2 wires (I think) to your wire harness
3. You will need a 300m/300m special computer.

You need to be able to reprogram the 300m computer so that your anti-theft system will work and your milage is correct.

From my research you will need another computer.... if you had a 2002 you wouldn't. DC used the same computer in all LH cars the first year. After that they started making different computers for each model.

Malcrow, you're from Detroit? I guess you're probably familiar with my hometown of Windsor. I guess now I'm really your best friend.

Why would I need a 300M computer? I know the 3.5 HO V6 is available in the SXT model line, it uses the 300M computer?

Is there anyway I can do this without the 300M computer (using what I've got in there right now)

The other thing is, I don't have the factory alarm, only the sentry key system, I want to put a factory alarm, but I just found out today that there is no hood-pin switch (which is used in the factory alarm).

A 300M engine controller would have slightly more hp than the SXT.

The 2004's have two diffrent NGC's (engine controllers) one for the 2.7/3.5 and one for the 3.5 H.O. The 2.7/3.5 NGC physically lacks hardware removed for cost cutting. So you need a 3.5 H.O. NGC.

With a sentry key the minimum you need to enable the alarm is the right trunk lid wire harness and the trunk latch key sense. with these parts all you have to do is connect the DRB III and enable the alarm. But the only way to disable it would be with the keyless remote. To be able to disable it at the doors you to run wiring into the front doors and cylinder lock sense. We never used hood pin switches for the factory alarms.

There's no pin switch on your hood becaues the OEM alarm doesn't monitor the hood. You could pop the hood and probably remove the engine and the OEM alarm wouldn't even notice. This of course is assuming you can pop the hood without getting to the inside release lever (yes it can be done)...

WOW are you serious??

Also if you disconnect the Battery I assume the alarm will not work???

If so wouldn't it be easy to break in if a person parked with their wheels turned and you open the access panel and disconnected the wires?

Not to change the subject but would it be possible to add switchs for the hood and the batter access panel?

This is exactly why it's a good reason to go aftermarket. Actually, someone could simply break the window as well to reach in and never trigger the alarm. The OEM alarm won't wound unless a door or the trunk is opened. It truly provides little protection...

The factory alarm will still arm (or continue to arm I believe) if the battery is disconnected.

When I had my neon (with factory alarm), I had the EVS II alarm installed. If anyone so much as bumped my car when parking, or hit the A-Pillar lightly, the alarm went off.

There is no backup battery that I know of for the system, so it will not work with the battery dissabled. The EVS II alarm is a dealer added "aftermarket" alarm system with the Chrysler name on it. Basically, all it adds is a siren and a cheap impact sensor that's rarely ever adjusted properly. IMO, you're much better off with a higher end aftermarket system. Even if it's one that interfaces to the OEM keyless system...

Even easier is to just take a steel rod and stick it through the access panel and battery...no more battery...no more alarm.

or simply cut the negative lead on the battery...no more alarm.
