RE: motor question
If your looking to buy a new SOHC then you should check to see if Mopar Performance still has the IT (Improved Touring) Crate Engine available. It was built specifically for SCCA IT specs and puts out 160 HP and 152 TQ. It's part number is P5007275.

RE: motor question
They changed the crank signal and lowered the compression ratio for the 2003-up model year Neons. Don't bother with those unless you want a serious project and great lessons in frustration...
I'm assuming by "engine" you mean "long block"? Then yes, it's essentially the same engine. It's the same block, same pistons, same cam (from 1996-up, except the magnums), same head (EGR port blocked off or never drilled starting on 2000 models), same oilpan from 1996-up, same oil pump, same timing belt setup... yeah, same engine essentially.
Don't forget that the Magnum (2001/2002 ACR's and R/T's) are also an option. You get the same short block, but a head that has a much better cam (2001 better than 2002-up), much larger exhaust ports, and better valvesprings that can handle any cam you put in there (not that there are many). Those engines were rated at 150 HP, but that's with the magnum exhaust manifold (almost a header... better than the regular log manifold), and the dual runner intake manifold (operated by the PCM normally, but that's easy enough to fix).
Your 1st gen motor mounts will bolt right up to the 2nd gen motors. No worry there.
Your 1st gen wiring harness will work fantastically with the 2nd gen motors, including the Magnums. You may have to swap over a couple of sensors on the engine because the connections are different. And you'll need to move the EGR system to the 2nd gen engine to avoid a CEL, or just get a Mopar PCM.
And speaking of PCM's, your 1st gen stock PCM will run a 2000-2002 engine, including Magnum, just fine... with your 1st gen wiring harness, of course. A Mopar PCM would be a better match for the Magnum engine though, more airflow and a higher revving cam and all.
Your stock 1st gen intake manifold will bolt right up to a regular 2nd gen head, since they are the same. Oddly, it will bolt right up to the Magnum head as well since the bolt pattern, intake port spacing, and intake port size is identical. Only the exhaust ports are changed on that head - raised and enlarged.
The IT engine is nice, but it really is a chunk of money to spend for what you get. Unless you are planning on racing in a class that limits you to that engine, you can do a lot more for a lot less. Those numbers are valid when used in conjunction with the class approved "trunk kit", which means an Iceman CAI, Mopar PCM, SOHC Mopar header, Mopar underdrive pulley, etc. A junkyard block, cleaned and bored .020 over, and balanced with its new forged 10.5:1 pistons and long rods, along with a Magnum head with a Crane 0014 (or Comp 400), mild port/polish, Magnum intake manifold operated off an RPM window switch, is going to cost about 3.4 as much and is going to make more power with the same bolt-on's, even more with better bolt-on's...
Best of luck!

RE: motor question
The Mopar Performance catalog doesn't have the prices listed, so I have no idea how much the IT motor is. I know the prices of all their V8 crate engines through ads, but I haven't seen anything but the V8's advertised.

RE: motor question
When I was pricing the IT engine about 4 years ago it was $2900, plus shipping, and that was from Fenton Dodge (serious discount pricing). Just did a google, and found a few places that have them at $3150. Needless to say, I never got into the roadracing circuit...

RE: motor question
That doesn't seem too bad for a brand new high output engine, but they use a remanufactured short block with a new head assembly. If they gave a warranty with it it would be a good deal, but their warranty on the crate engines sucks (90 day). It would be more cost effective to just rebuild the one you've got or buy and build another.
I always wanted to take mine out on a road course, but never got the chance.
