Tested it out... not getting voltage to the CPS connector, but the PCM is good. Ideas?

Here's a big hint to everyone: The coilpack connector and camshaft position connector will fit each other's sensors... so make sure you plug the right one in! lol

My swap is still running strong. I cannot get the fans to run to save their life, even with the fan mod the relay just clicks. Gonna have to see WTF is going on with it.

Will a R/T intake manifold work good with a SRT. I plan on doing a SRT swap but the SRT I am getting he sold the intake manifold already. I can get a intake manifold off an R/T but wanted to know if they would be ok?

For one, it will not be a direct bolt on, and I have read that it will not flow well enough, but I doubt it has been compared on a dyno vs an SRT IM under boost.

Ok. That is cool. I new a junk yard that had an R/T with an intake on it and since I am going to due a swap to an SRT and needed one figured I would take a chance. I am going to do a little bit more reading cause I have read a bit about swapping into a 2001 neon you have to do a couple of things different.

I purchased a Sxt with the swap already done...my question is how do I connect the Srt A/c Lines to the firewall of a sxt?

From your question, I'll assume the car is a pre '02/'03, and the A/C plumbing connection is different. You will need the HVAC module from a newer neon inside the car, for the newer lines to hook up, or have someone custom make an adapter. AFAIK, the inside HVAC should be the same for all 2002? 2003-2005 neons. I know they changed the underhood plumbing, but I can't recall if it was in '02, or with the whole NGC '03 change.

Sorry forgot to mention it was a an 02...original owner said the firewall adapter was different and I probably had to get a custom adapter made. I was just checking to see if there was an easier way.

You could use the '03-'05 underhood lines, and have a shop crimp on some short rubber A/C hose to the '02 plubing firewall flange. Might work, might not. I know the two systems are drastically different, as to the drier location, etc. There is no simple way, other than having custom lines,etc. made from the SRT compressor to the firewall. Maybe an aftermarket A/C shop that does street rods/customs might be another choice, other than taking out the dash, and swapping the HVAC module. Vintage Air is the only place that comes to mind, ATM.

I have gotten me a donor car but have a question. On the list of things to get it talks about:

Sentry Key Module + Key that matches the PCM VIN number.

Is this stating that I need to Key for starting the car? Or is it a dongle like piece? Where would it be located?

### Update ###
I found a link to a manual online and when I looked it up I found what I was needing to get.

The key module wraps around the ignition and is bolted down to the steering. I believe it has the makers name on it "Siemens". This, the key and the PCM all must has the same VIN in order for the car to stay on when she's turned over.

You need the key that matches the module and PCM. The key is chipped to the module. The key module has a 4 digit code, IIRC, and that code has to match the VIN and vise versa. It is not just 100% the VIN.

So when you do a swap you will have a different key to unlock the doors and to start the car?

If you have a key cut to you ign switch that is programmed to the SKIM receiver ring, then no.
OR:
Unless you have access to get the locks from the donor car.

Or as I have previously suggested, have a new set programmed, and cut one side for the ign., and one for the doors/trunk. Wally world won't be able to do this, but a hand guided key machine will.

lmao. I had a "friend" that was afraid he had an STD so I asked the Dr. if that could make someones dick fall off. He said no... then told me to just penicillin, I'd be fine. :rofl:


Moral of the story... I have no idea at all. Hope you get your friend an answer though because that's a good question.

ok thanks.. hes wants to keep it.. for what ever reason he likes the traction control.. hes thinking about srt rod/pistons, turbo, intercooler,ect but with a pre 02 2.4 block and his stock r/t vehicle wiring. but with a rising rate fpr, and bigger injectors for fuel mods. he should be good that way then right?

As far as traction control, probably. If he was using the pre NGC block, the SRT PCM wouldn't be an issue anyways.

ok cool ill let him know.. i think he'll be doing the srt rod/piston pre 02 2.4 block then with his stock r/t ecu, wiring, srt fuel pump, srt injectors, rising rate fpr, spoolboy mod for fuel along with a wideband and to tune it..

anything he's missing for tuning and fuel?

ok i got a question hopefully someone can answer..

im going to do the engine swap sometime this summer in my 03 RT will i need the srt4 axles or can i just reuse my RT axles..? if i get srt4 axles will they fit into my hub or do i have to change that out as well to srt ones..?

I plan to use my brake setup as its already a good setup compared to swapping to stock srt brake setup.

If you are using SRT t-850 trans you will need SRT axles as far as I know.

And I think you will need Srt hubs. Not sure.
