Magnum swap questions (plenty) please help

[azzkikr37]

I currently own an 03 NGC SXT and would like to swap it or make it into magnum....
Currently my mods are :
-Iceman CAI
-60mm TB
-Long tube headers w/ full custom exhaust
-Nology wires w/ NGK iridium
I recently bought the R/T intake manifold, an MPX udp, stock R/T headers, 02 R/T PCM (which now I realize I cannot use) an r/t head and valve springs

1st question – Will my original aftermarket kirk long tube headers meant for a standard neon be sufficient or should I put the stock R/T headers OR buy new aftermarket headers meant for an R/T?

2nd – Are the R/T trannys the same as ACR? If not which one is better? Do I need the 03-04 tranny to fit my car or could I also use 00-02 ACR/RT?

3rd – What exactly comes in a head , I bought a SOHC R/T head with valve springs but is not 100% complete, I want to know what goes in it so i know what im missing plus Are all SOHC heads interchangeable, 1st and 2nd gen (including R/T) or since my car is an 03 I have to stick to 03+ heads?

4th – Is there a difference in block other than the pistons in the R/T? Are the rods that different that I would have to get one?

I will have more questions as the project progresses, any information will be helpful. I’ve been in the neon game for a while but I’m getting into the motor now so I became a member to research.
thnks

Heyyo,

Just wanted to welcome you here and give you a friendly heads up that this will probably be moved to the Motor swap section.

Why can't you use the PCM?

1st question – Will my original aftermarket kirk long tube headers meant for a standard neon be sufficient or should I put the stock R/T headers OR buy new aftermarket headers meant for an R/T?

The Kirk should be fine. I think the holes are big enough for both applications.

2nd – Are the R/T trannys the same as ACR? If not which one is better? Do I need the 03-04 tranny to fit my car or could I also use 00-02 ACR/RT?

Yes. No.

3rd – What exactly comes in a head , I bought a SOHC R/T head with valve springs but is not 100% complete, I want to know what goes in it so i know what im missing plus Are all SOHC heads interchangeable, 1st and 2nd gen (including R/T) or since my car is an 03 I have to stick to 03+ heads?

I have no idea. Yes, they're all interchangeable.

4th – Is there a difference in block other than the pistons in the R/T? Are the rods that different that I would have to get one?

The rods are different, I think, yes. But only in the durability. Someone correct me if I'm wrong.

I will have more questions as the project progresses, any information will be helpful. I’ve been in the neon game for a while but I’m getting into the motor now so I became a member to research.

Good. There have been a few topics lately about people swapping to magnum, and I'm sure there have been lots in the past. Make good use of the search function.

Also, I think you're going to need a different CAI. Pretty sure regular CAIs won't fit with the aluminum manifold. At least, I think that's why I keep seeing CAIs for magnum engines only...

Can't use the PCM because of NGC engine. Crank sensor is incompatible.

[azzkikr37]

yea thats what they told me thats why i would really appreciate it if someone could tell me everything in detail so i wont buy the wrong things like the pcm

[unleashedcc]

apparently 00-02 RT PCM won't work with 03-05 years since they are NGC

Oh, right. Didn't see that.
