What exactly is the difference between an srt and pt gt engine. I know the intake manifolds are different, but is that all. Also, did dodge make a stage one for the gt's? I found an affordable engine complete with harness and PCM. I also was wondering if anyone has tried to buy a new skim and ignition with the same vin instead of a new PCM to get around the anti theft. Otherwise it looks like I need a harness, computer, and manifold to make it run.

They did make a Stage 1 PCM for the GTs for sure...sorry I can't answer more questions...

It never occured to me that Modern would probably carry it if it exists. So why does everyone do a harness swap and such. Couldn't you just buy a new stage 1 PCM for the pt engine and splice the dash harness?

The GT and SRT block's are the same!!! intake is diff. wiring harness is diff.. if you were gonna swap the hole thing into your car you should check out 2gn.org for more info on the ECU setup... lot of guy's have swapped in the auto and used the GT ecu.... Good luck

The harnesses CAN be spliced, just not easily. The underhood harness AND engine harness are different for the PT than for the Neons. I've never seen the dash harness in the PT, so won't wven venture a guess.

I started with a GT cruiser motor for my swap. After looking at the time needed to splice, I clicked the "buy now" button for a new harness.

So if I decide to go the new harness route, where can I get one cheap. I called my dodge dealer and they wanted $250 for it. Also, are the sensors on the two engines the same? I really don't want to buy a harness and have to either splice all the pigtails or buy different sensors to match the harness.

Srt Forums is a good place to start for used ones. I recently helped someone find a new one for 150 shipped (engine harness). In fact, I found several new ones for under 175 (shipped).

The sensors are the same as on the SRT-4 Neon. The ONLY connector that MIGHT be different is the alternator connector. There was at least one change to these. I had to swap connectors for my PT Turbo alternator. A three and a half minute change (including the beer slurping).

All turbo blocks have the squirters, SRT and GT Cruiser. NA blocks don't have them. All '03-up blocks have the passage and casting for the squirters. They can be machined for them if desired.

Thanks for all the reply's everyone. I started searching for an engine harness and opened a whole new can of worms. It looks like there are several different harnesses. I came across an engine harness which looked pretty small, another harness with the fuse box in it, a dash harness, and a body harness. Are any of these just different names for the same thing or are all these different?

There's 3 basic harness', the front harness (with the PDC, headlights, etc), the engine harness, and the body harness (which the dash is the major part of). Then there's the door harness', and minor add on stuff.

I'm pretty sure that's right.

im in the process of "converting" my gt motor to a srt...so far ive found that the oil dipstick is a bit longer, and the waterneck is taller and tilted differently. and i think the gt uses all 4 plugs on the pcm with the auto tranny because i have and extra plug

It definitely uses the 4th plug for the ATX. The TCM is integrated into the PCM on NGC vehicles.

After looking into this option, I think I am going to try and find a parts car so I can swap everything instead of trying to piece everything together. Thanks for all the answers everyone.

I ended up cutting off some at the top of the tube, and cut the top of the dipstick the same amount. Prettty ghetto, but it worked.

you know if a older 2.4 one out of a stratus will work?

As far as I looked into it, the TCM from a Stratus may work to control the trans, but you'll have to wire the PCM inputs (signals that the PCM relays to the TCM in the Stratus) straight to the TCM, and it still won't have a com buss to the PCM, so it may go into a limp mode even after all of that work. Hence me not pursuing the Stratus TCM route any further. I can't afford to take my car down, swap the trans in, adapt all of the wiring, and then have it flip me the bird and limp mode on me...
