2nd gen DOHC swap

das2123, i have a good feeling your gonna make this easy for me..i've been trying to find info on this swap for 2nd gens, but i dont know if it's identicle to sohc to dohc swaps on 1gens.., obviously 2nd gen is sohc.., is this worth swapping in the 2.0dohc?..is it hard, like making new engine mounts, or is the motor a direct bolt on?..i know i'd need the dohc computer., but thats all i know pretty much..any info would be great..haha...thanx

If you are wanting a little more power you can do a SOHC Magnum Head, intake manifold and computer upgrade and come out with the same 150hp as the Dohc with a lot less effort.

i already know someone who did the magnum swap around here.., in his 2001 lx.., i like the extra 500or so rpm..so i was wondering if it would be worth tryin

neondawo, you can put the 1st gen DOHC engine into a 2nd gen, but it's not real popular. Most people opt for the Magnum engine or better yet the 2.4 engine swap. I'd go with the 2.4 swap because you can obviously make more power with the 2.4DOHC than you would the 2.0SOHC magnum. One of the problems with the DOHC swap is the ECU.

but it's not real popular==>...thats another reason why i'd like to do it.., i dont really care about the power, if i wanted power, i'd buy a srt-4 and mod that.., but i'd like something different than others around here..so what do you mean there's ECU problems?..how would i have to fix them?..thanx

darylThe biggest thing would be the pcm. Remember the 2g clusters are a bus data rather then the 1st gen magnet style. Wiring harness from the DOHC would be needed, as it is different from the 2nd gen ones. Also there is no passenger side mounting brackets that exist for you to bolt the DOHC engine into your car...you will have customize this.

These are a few things I can come up with off the top of my head. If I were doing this swap, which I wouldn't, I'd get the DOHC engine and wiring harness and a first gen cluster to swap in. I don't know if this would work because some sensors may be different. So I don't think it would be plug and play. This would be a swap you may have to do on your own without much help from others because like I said, it's not a popular swap. Most people want to go with more power like the 2.4.

If it's power you are looking for, I would suggest a Turbo on the engine you have.
The SRT 2.4l swap works b/c it is designed to work in a 2nd gen. If you are looking to put in a 2.4l (non SRT) or 2.0L Dohc you may have some really large obsticles in your way. Mounting the DOHCs (2.4 or 2.0) would be the easy part compared with the Engine Management mess you are going to have.
Buy a 1st Gen project car and then put in whatever engine you want, it would be much easier that way.

oh..alrite.., maybe i'll just stick with the magnum head., i figured this would be neat to have dohc 2.0L in a 2gen, but by the sounds of it, i dont think i'll do that anymore.., thanx das2123

darylDon't mean to discourage you, but it's one of the harder swaps for the neon. A magnum engine would be good, but I vote for the 2.4 swap :grinyes:

the 2.4?...isn't there a lot of work involved in the 2.4 swap?.., much more than the magnum.., and if i did the 2.4, would it be reliable?.., and would i also do the turbo set-up.., or?.., let me know wut u would do if u were me..haha..thanx

daryl

The 2.4 SRT and the 2.4 Non-SRT use different controllers and sensors. You can put the 2.4 SRT setup in a 2nd Gen and then use the Stage1 MP controller ( b/c it doesn't do a VIN# security check), it is much easier than swapping in a non-SRT 2.4l non-turbo setup.
If you do a SRT transplant, it is helpful to buy the whole car and take what you need from the donor car to make things work.

ahh...just buying an srt-4 sounds easier..haha

ahh...just buying an srt-4 sounds easier..hahaThe insurance will be higher on an SRT :grinyes:

The insurance will be higher on an SRT :grinyes:

haha.., put it this way, if i were to spend this much money on a neon.., trust me i'd be able to afford the insurance..haha:grinyes: .., but i also am an all out neon person.., no matter what:sunglasse..just wished i knew more about them.., never liked them until i bought my neon about a year ago.., then started joining car clubs, and started to really like my neon

just wished i knew more about them..This is a good book that will help you and teach alot about modding your neon. I know one of the guys who helped write it and he is very knowledgable about neons...

nice...i shall buy that!!

Anyone out there try putting a Magnum SOHC Head on a 2.4L engine? It seems like if you put in the 2.4 and attached the Magnum Sohc head, intake, exhaust and put in bigger injecters, you would have a good running combo, if you could find a timing belt of the proper size.
If you only used the non-magnum head and intake, I would think that there wouldn't be enough air flow to give it the same torque curve of the original 2.0 non-magnum engine. A Magnum head (w/cam) and the Magnum intake (with the runners set on secondary) may approximate the air flow of the original Sohc engine closely enough to make the computer think everything was OK. You would need 23 or 24lb injectors to make up the 20% more displacement of the 2.4L. Just a thought, I was hoping someone may have tried it before. If it ran OK, it would solve the 2.4l ECU problem. It would also look completely "stock" so the emission dudes wouldn't suspect a thing.
