Has anyone done this?

I am really thinking about doing a 2.0 DOHC motor. I read somewhere that Gary Howell did a swap, but I don't remember. I don't want to run it on a standalone because I have emissions in my area. I'm thinking if I use a 1st gen engine, I could use a 1st gen aftermarket PCM (Mopar, or AFX) and keep my OBDII compliance. I don't want to do a 2.4 because of the added weight, it's still a toss up of N/A or turbo. Turbo makes tons o powah....N/A sounds cooler

.

Any ideas?

Id have to say that 'added weight' is a bit of a bad excuse for not doin an srt swap. the only added weight id be interested in is the LBS of BOOOOOST! go for the srt swap, its straight forward and will run on a OEM PCM, plus youll be able to actually find aftermarket parts for it. A custom setup requires custom upgrades! I think a DOHC 2.0 would be cool, but cost more than its worth.

ps and i also have to disagree about the na sounding better than turbo. you cant beat the swoosh of a BOV! mmmm..

2.4 wont be added weight, just ask them SRT-4 Owners and Swapped guys!

well it was done and in the 03-05 neon all tha iis needed is the dohc head pcm and switch. its pretty easy and he won the four cyclindar challange with his converted 03. and after that all you have to do is find the turbo goodies if you are so inclined and make a poor mans srt-4

i wouldn't mine just goin 2.4dohc n/a all motor....be different and nice imo....

I'm not afraid of doing the wiring, but will I have to run an external crank trigger? Or is the crank sensor in the head itself? I'd really like to look into this more. And I don't want turbo lol.

I would love to drive something with a 2.4 N/A with a manual trans. I've driven a ton of regular 2.4 cars, but they were all automatic. My 2.0 5-speed feels much more punchy than my mom's 2.4 automatic Stratus. I really want to see how that low end torque feels behind a manual.

Anybody done that?

Friend of mine put an N/A 2.4 into his 1st gen R/T. I've never driven it, actually haven't even seen it yet, but he says he has serious traction problems now, and he runs fat Falken Azenzi tires....His car is kind of gutted though, and it's a 1st gen two door, so it's pretty light. ANyway, it's faster now than it was when it was a stock R/T engine with every bolt on, including FF long tube header, and an MSD DIS-2 ignition and AFx pcm.

id say go for the 2.7 stroker but howell doesnt offer it anymore.... and as good as turbo spool or BOV "pop" sound, a cammed-up NA engine will ALWAYS sound better in my book

i had the 2 door stratus with the 2.4 in it (same as the eclipses) and i can tell you that i feel my neon is quicker... a little bit less torque.. but seems to be just enough to notice the difference.

stock 2.4 motors in neons run slower than the 1gns but if you get mods in it it becomes a beast....

double sausage: that 2.4 is different than the one they are talking about. that 2.4 is a mitsubishi sohc engine. they are talking about the 2.4 dohc that comes in 4 door stratus's.

dinetuner: do you mean a stock 2.4 in a first gen or a sec gen?

so is it better to run a 2.4 stratus then a 2.0 dohc i have a turbo and all that and im deciding and need to make my decision quick i might even bore and stroke teh 2.0 to a 2.4 but what do you guys think

INVUJerry · Post by **INVUJerry** » Sun Apr 23, 2006 1:51 am

A 2.2 stroker kit is gonna be huge cost. Swap to DOHC, and run a standalone engine management, if you aren't afraid of alot of headaches.

both.. you need headwork to get it moving.. if not by the time you get traction the powerband is about spent...

2.4 high compression n/a cars where quite common in the early neon years, before everyone started going turbo. i remember when swapping in a 2.4 was all the rage, and lots of people had good results, so you should expect nothing less; you dont need an srt block, you can use any pt, stratus block which'll be a lot cheaper; the low compression slugs in hte srt arent good for n/a buildups, and stock srt pistons and rods are cheap and can be swapped on either of the 2.4 blocks/cranks

see i was wondering i have a dohc 2.0 ready to be machined and put all kinds of good stuff into it...but the more that i read i hear it is better to go with the 2.4 stratus motor(no placement for disp[lacement) but i was wondering forst if i should go with the 2.0 dohc or i should go buy a 2.4 stratus motor and also i wanted to know will the computer from my 2.0 dohc (1997) go into my sohc (1995) car......so basically will it be more headaches to with the 2.4 dohc or the 2.0 dohc i hear 2.4 have the traction problem.

dinetuner · Post by **dinetuner** » Sun Apr 23, 2006 12:16 pm

2.4 has more pontential yes they have traction problems thats what they make slicks/DR for

personally id stay with the 2.0 unless you really want the 2.4 mainly becuase \
1. you have it its gonna cost money to get you a 2.4 and that money can be spent on go fast mods
2.wieghs alot more
3.has alot of torque down low(ie traction problems)
4. doesnt like revving too high

Is a 2.0 DOHC possible in the 00-02 HO engine? and would it make any more power than the presents HO's 150? Aren't stock DOHC 2.0 in the Neon at the 150 crank hp???

yes the diffrence in a "normal" 2.0 and a HO is top part of the engine.... they made less than 150hp at the crank for the fact that dodge overrepped them but they did are more "tuner" friendly and can run higher compression(sure you can run massive compression on a SOHC but your gonna need some real custom cams). if you are going to convert over to DOHC head use 01+ becuase they have larger ports and all and would be a better base to do a P&P

what PCM would u need to run. i am interested in this.

dinetuner · Post by **dinetuner** » Sat May 20, 2006 12:13 am

i have no idea never gave it thought...lol you could go standalone and use a basemap then tune it from there
