this might b a noob question :lol: can a stratus 2.4 block fit in a 2g using the same 2.0 motor mounts? and will a sohc head fit on it?

MMs, possibly, not sure about the head. But the question is why you would do that when you can just do a 2.4T swap which is nearly the same thing, possibly easier?

idk it was just an idea i thought it would cool to do a 2.4 sohc na and im sure someone has tried it but ive never seen it done

have fun possible but not worth it. you cant buy a cam large enough to run well with that 2.4

The Stratus 2.4 will fit, but not just using the 2.0 mounts.

I have a custom subframe/engine brace, custom secondary transmission mount, and a modified SRT mount for the upper torque strut. The only mount that worked fine was the stock transmission mount because I used the 3.55, so everything was the same there.

The main reason I went with this swap was for the uniqueness. I like to do things outside of the box. I only know of one other guy who did this swap and the car was totaled shortly after he got it done. As far as I know, I'm the only person running a non-SRT 2.4 turboed in a 2nd gen.

It certainly provided (and still continues to) a unique set of problems and challenges compared to just going with an SRT swap.

damn i would like to do it anyway but i dont have too much money to work with things r a little rough rite now. how about a 1gen dohc head on a 2gen sohc block?

You may have to change CPS for it to work, but people have put the DOHC head on second gen neons

I am about to do this swap.......and I dont see what would be so hard about it!?!

How would it be any different than putting the srt-4 swap in??? And how on earth would it be harder? Im not talking about making a sohc 2.4 but why does everyone think there is no way to go other than putting an srt engine in??? You have to swap everything..ie. entire wireing harness, interior harness..everything..at least if you have a pre-ngc car that is.

You know the 00+ stratus 4 doors and pts have the same mouting system as the neon. I know atleast the pt's do.

At the very most, all you would need is a set of either srt front and side mounts or pt mounts which should bolt right up to the 2.4 given the year is appropriate for your car. That gets the motor to mounted into place. You would also want to use the pt brackets for ps, ac, and the alternator and you have to perform a few minimal wireing alterations. But thats it. No screwing with the entire wireing harness, no spending 4 grand on a donor car, and no screwing with ngc if you have a 02 or older.

Some people like n/a and puting a n/a 2.4 into a second gen would be relatively easy and not that expensive.

This was not aimed towards anyone here.....just the general consensus on these boards that its srt or no.

easy there...

People are telling you that it can be done.

What you're not getting is that some say it's not worth it. The stratus 2.4 engine produces 147 hp. The magnum 2.0 engine will produce 150. Dodge measured both at the flywheel.

The 2.4 blocks are the same so they will fit with the same dimentions (motor mouts, torque struts, etc). People put srt-4 internals into non srt blocks I believe because they are more "reliable." If you have the same dimentions with just a turbo manifold at the back where there would be wasted space and you've gone through the trouble of wiring and swapping engines, why not get the extra power?

I knew that seemed like I was ranting....sorry.

I see where you are comming from there. It would be rather easy once you've installed a 2.4 to go ahead and turbo the thing.

I see a whole new headache when trying to turbo a car though. If I did want to turbo it I would deffinitly use srt parts n such but the point I was trying to make was that people here seem to imply....no matter what the person asking really wants...that they would be wasteing their time unless going turbo.

I think a stock 2.4 swap would deffinitly be worth it because you are getting a real 150hp and more torque at lower more streetable rpm's. And for those who are n/a fanatics, the 2.4 is more responsive to upgrades and it allows you to keep the factory fuel system (except the injectors), ecu, and wireing harness. No headaches, no reliability issues...(unless you do the whole srt swap and keep it "STOCK").

Install the 2.4 and you have a very sound and capable n/a power plant that will move the neon quite nicely and you wont have to rev the thing over 5 grand to get the extra kick.

Just me .02. It just seems like a no brainer to me but to each his own.

Just so everyone knows.....I understand this was a little out of place. The op was asking if he could use 2.0 mounts and put the sohc head on it......you cant use the 2.0 mounts and you cant easily put the sohc head on the 2.4........that would deffinilty be harder then doing an srt swap.

If you want to go na then find an 01 pt cruiser and yank the engine with all the mounts and accessory brackets....this would be the simplest way. The dohc head changes a little in 01 so if you plan on useing pre 2nd gen dohc intake and exhaust the you would want to find a 2000 or older unit and just add all the pt mounts and brackets on. That is what i am doing.

Then all you need to do is search a little......change the coil wires accordingly, swap the injector plugs, and set up the cam position sensor and you would be golden.

Once you do this you will have the option of adding srt internals later on and bolting on the srt turbofold if you want to go turbo.

What it boils down to for most people is that it simply isn't worth the gains (yes, more torque...but still not a HUGE change when going stock for stock) to go through with this swap.

A number of members are going to steer people away from an NA build because time and time again we are shown that it takes far more money to get that type of a build even close to the potential of a turbo build. Member after member ends up abandoning their NA platform to go turbo. The holy grail of 200hp+ on a Neon NA build is fairly easily surpassed with a turbo setup. That said, I am not putting down NA builds by any means. I have seen some truly amazing and impressive NA builds on other platforms. I'd love to see an NA build on the Neon platform that really blows me away, but as of now, that hasn't happened.

The SRT swap is, and will continue to be, the most popular swap for the Neon platform. For the price, you simply can't beat the potential. Add into that the number of people that have tackled this swap and you have a pretty good base of enthusiasts that can offer technical assistance, advice, and know-how.

The non-SRT 2.4 swap is, for the most part, uncharted territory in the 2nd gen world. So, naturally, that is the route I went. I am a glutton for punishment, but that comes along with dwelling outside the norm. In order to actually give myself a good amount of potential I decided to boost it and run Megasquirt. Any swap is going to have its fair share of headaches but with this one you are more or less on your own to figure them out. Although, I did find the 1st gen 2.4 guys to be a good source for information and a handful of members on here for some more specific 2nd gen info.

Basically, what I am trying to get at is...most of the members here are going to cry 'SRT swap' because that is the tried and true swap. We have seen it time and time again. The potential is there, the technical knowledge base is there, and let's face it...it is a really solid engine to work with.

From seeing your posts around the forum, it looks like you have more knowledge than the average person who asks about swaps and the like, so I am sure you will do fine. I can see where you are coming from on your build and I look forward to seeing you bring it to fruition. Let me know if I can be of any assistance. :thumbup:

Oh, and yea...this thread kind of went two different directions, but I think everyone had their questions/thoughts addressed. :runaway:

I have to say, that was well said!

I understand the bases of your "arguement", as it explains very well why everyone on here is biased towards the srt swap. I...like you...tend to favor the road less traveled hence the reason for my decision to go 2.4 n/a.

I am from the .org and it is quite common for someone to go n/a 2.4. So it is hard for me to understand why on one neon website n/a can stand its ground among the masses but on another neon site......the idea itself is shunned.

Of course a turbocharged neon is almost always going to be faster and will most definitly have more potential so there is no argument there. On the other hand, people who want to try something different should be able to come on here and ask a question or make a statement without having biased oppinions thrown at them from all sides.

I used to be into 1st gen awd talons. I had three of them, each set up with a diff. turbo (stock/16g/50trim) so i know what a turbo can do. Let me tell you, those things would roast some of the hottest srt-4s around yet you guys stick with the neon. Maybe its because you like mopar or maybe you want to be different, but it sure as hell is "not" because they have more potential than some of the other cars around. Thats the point im trying to make. People need to be open to other ideas...those guys over at dsmtalk make it their jobs to make fun of neons because they are always at a dissadvantage to anything that has awd.

If everyone was so concerned about "potential" then they would need to move on!!! But thats not the case, the whole idea of being a neon junkie is to be different. Thats where the frustration comes from as here you are either stock or tubo'd....theres no accepted gray area. Thats not even touching the idea of swaping a 2.4. Concerning the n/a crowd...swaping a 2.4 would be a sound upgrade. The potential is there...wether you want to stay n/a or if you deside you want to throw some srt internals in and go turbo...there is no real downside.

I am going to do this swap...and I will do a write up or seek some assistance in doing a write up so that everyone could see thats its a far cry in complexity compared to a full srt swap. Maybe it will spark some intrest from those who want a fun dd....rather than something that could run 12's.

To the op.....sorry for highjacking your thread. I hope your questions were answered here.

why not just put a dohc head on your motor, or a complete 2.4 dohc in the car. you can run it off the stock sohc pcm aslong as the 2.4 is pre ngc. ultimately once you started modding the 2.4 a RRFPR would be helpful along with bigger injectors.

Back to the top.

For the OP...you are not alone. I have been playing with the idea of doing just what you mentioned, 2.4 SOHC. My reasons for this are...

I want N/A for my ACR.
I want to keep a stock appearance.
I like the idea of a punched out 2.4 (2.6 anyone?)
And, like Chris said, I like to be different.

I'm doing some research now on the candidates for the donor. It seems that the 2001 PT is the best bet. No NGC, it already has the correct engine mount system, and the oil filter mounts to the back of the oil pan (instead of hanging down like the JA cars). Until I get my hands on a block I won't know what changes (if any) are need to mate the head to the block...mainly the oil passages. Then there is the matter of what timing belt to use :roll: A window switch may be needed to open the butterflies in the intake earlier :-k

Since I have the Magnum head, I know flow will be better than the DOHC. And since the engine won't need to rev as high to make power, maybe I can eliminate the stupid CEL I get from the "multiple cylinder misfire" using my UDP :cussing:

So don't give up on the idea. It just takes some research, brainstorming, fact finding, etc. Oh, and some good old elbow grease :thumbup:

Im also going to be doing a 2.4L NA in my ES.. We have a 1st Gen with a 2.4,stock bottomend,ported head,SRT oil pan and pump, Crane 24s, Rhoades Lifters, crane valve springs, AFX, MSD, etc... This car screems,, its very fast. The owner wants a build bottomend so that he can add his fogger setup to it. Im going to get the motor minus the cams and put in some Crane 18s for a daily driver. Im going to keep my 3.55 trans and use this to drive to work. I dont plan on going turbo,, not for a while anyway. Good luck with your swap. I will make a post of mine once I begin in a couple months.
