a few question

Post by SPARKZ » Sun Sep 16, 2007 10:14 pm

like i said before im going to swap out mt sohc ( auto ) to a srt-4 2.4 engine i just wanted to know if i could use my coil pack from my 99 sohc into the new 2.4 engine i need one for my 99 and hate to have to buy another one for the 2.4 in modern performance they have a msd coil pack i like and they also sell a DIS2 harness what does DIS2 mean do it your self 2.4 swap ? and my next question is the auto to standard ? what do i need for the change over ? im a noob i know plz dont rub it in, oh and for those who already done the swap is it better to go with a srt motor ar any 2.4 dodge motor what is the diff ?? and what up with blocking of the egr valve ??

If you are gonna do the swap, you'll need to get an older (pre-2003) engine otherwise you'll have a wiring nightmare on your hands and I doubt you'd be able to pull it off. Crank sensor pick up is different and you either need megasquirt or an SRT-4 computer.

All the SRT-4 stuff will bolt right to the older blocks except for the head but older ones have bigger valves anyways.

so your saying to use an older model srt an 03 or lower for wiring purposes is there a big diff between diff year models of srt 4 like is the 02 srt better than a 03 for example and what about the crank sensor, camm sensor and tps, does the original wire harness in my 99 comply with a 2.4 srt model engine or do i have to splice and sauter the conections from the donor model srt ? and i also noticed that a motor mount adapter is sold for the left mount what about the other two is there a diffrence in them aswell and the bobble strut for standards mine is an auto can i still put a booble srut is there a pre existing spot that all neons have to mount?

SRT's were only made 03-05. They are generally the same. The reason you want to use an older block is due to the fact that the crankshaft trigger wheel changed in 2003 and the 1st gen Neon PCM's aren't programmed to read that tooth pattern so they cannot run the 2003-up engine. Megasquirt can now, other standalones will work, and the SRT-4 computers will run it but those are way more involved as far as wiring goes. All the SRT-4 stuff will bolt to older blocks anyways so you can go that route. If you use an older block, the swap will be 20x easier to get to run. You really only need to swap 2 wires if you go from a DOHC to a 2.4. People say you gotta do injector wires too but I didn't swap mine when I went from 2.4 DOHC to 2.0 SOHC and it runs just fine.

like chip said pre 2001 2.4 are the way to go it was pretty easy i just failed to make sure the 2.0 intake cam was the right way so after i fixed that it started right up you should just look at the how to here its got a list of all the stuff you need and it straight to the point in case you have A.D.D. like me

Thanx so much guys all the info is good im glad someone threw this link to me i never knew the 2.4 could be swaped into my 99 neon i admit i thought about it when i first bought it but after looking at the 2000 model neons and there wishbone mounts and my mounts were diff i forgot about the whol idea im so glad most of yaw did it so i can refer back to yaw on questions but what do yaw mean on an older 2.4 do you mean like a 2.4 block from a diff model car other than a neon ? and what about that mine is an automatic and i want to be standard i know that my shifter cable from my auto goes straight to the tranny and when i do a 2.4 swap all i have to do for the manuel tranny swap i just buy the gear selector set up and run the cable to the trans but what about the foot clutch assembly do i need to cut a hole to acces the foot peddel to the tranny to ingage the clutch and what about the boble strut ???

And for earlier year engines, ANY Chrysler 2.4 from 95-2002 will work. Check out Stratus, Cirrus, Breeze, Caravan, PT Cruiser, Sebring and other cars made by Chrysler with a 2.4L DOHC. The 2.4L SOHC in some Sebrings/Stratuses is a Mitsu engine and will not work. It's basically the same block as the SRT-4 except one oil drain is different (will work with stock Neon DOHC head, same as 2.4L head) and the main thing is the crank trigger is also the same (except off 180 degrees, which is the reason you flop the coil pack wires). All the SRT-4 stuff (oil system, timing stuff, internals, etc) will bolt right up to the block and you can use a 1st gen Neon computer to run the engine.

the tranny swap you gotta get the manual trans, shifter cables, pedals, clutch, ecu, the bracket for the bobble so you can weld it or a manual k member, axle think its driver side and i think thats it but it will bolt right up to the 2.4

You can also use the auto trans, Jeff B's wife has a 2.4L auto N/A. Rode in it once Saturday night I was told but I don't remember. Guess I was hanging out the window puking :lol:

do yaw guys think it would be better to order a new block from dodge so there wont be any probs, i think thtas what i want and i think my neon pcm is broke any way so ill have to get another, and the floping of the coil pack mine is old my neon only goes a few blocks chokes and dies and takes about a half an hour before i can go another six blocks till it happends again i think its original and i have way over a hundred and fifty thousand miles so it needs changing i was thinking msd, that one of the lil things i want to buy friday, so i will be perpared. and instead of stock srt internals what about something more advanced like power forged pistons and titanium rods and valves , do yaw have any good sugestions on what is better to use for more hp. i can get those cheap...and as far as my current engine its a sohc :cry:

Don't waste your money buying a new block from Chrysler, get a junk yard motor and have the machine shop che3ck it out.

You can always buy forged internals if you want to run LOTS of power, from what I understand SRT-4 internals are good to at least 350whp though I'm not sure to what limits they have been successfully pushed to.
