2.0 to 2.4

[talonator1488]

I have a 2.0 420a but i am goin to build a 2.4(found in 4 door neons) up for a turbo and nitrous. What are the differences between the two motors. Is it a direct swap for the two? What mods might I have to make? Is the wiring harness the same? Also can someone tell me if the 1g turbo injectors wil fit into the 420a? Thank You

First at all everithing is possible, but is goig to cost you a lot of work , time & money.
the 2.4 in the neon( neon has 2,4L ?? anyway) is different that our engines, they share the block of the engine but that's it. the swap is going to be horrible. The upper head is opposite to ours.

Just do a research in the SEARCH FUNCTION , that is available in this web site. Just hit 2.4L swap or SWAP. ( Also search at www.2gnt.com)

What it is possible to do is use the block of the dodge stratus (2,4L), use our upper head and them is when the PITA start. belive me, i want to do that.
Mount, wiring, oil panel, brackets, etc. But i have to be patient until somebody do the SWAP KIT. Soon is going to be maded by someone. be patient.

By the way too many questions at one.
I hope this help

Why not the 2.4 out of the spiders? Would they work 4 a motor swap? I would think that would be easier to do then to build up another motor...hmmm....sounds like fun though, i wanna try! Weeeeeeeee

 

[talonator1488]

I could swear that I saw an engine in a 4 dr. neon that was almost identical to the 420a except it had 2.4 on the valve cover instead of 2.0. I will go back to the j-yard and check it out I could be dreamin. . Could I get the bottom end out of a stratus 2.4 and get the same results or is there a different bore. Still can anyone tell me if the 1g turbo injectors will work on a 420a.

 

[talonator1488]

By the way Thanks tito. That does help. Isnt the 2.4 in the spyder a single cam. J/W?

Hey tito your right down the interstate from me

Hey BTW do not confuse the 4g64 2.4L of the spider they are a Mitsubishi engine (way different that the Chrysler engine) It won't work at all.

About the injectors , I guess that those are way to much for our stock 420A unless u do the 2.4 L swap and then u need a little extra fuel but other than that u will be running really rich if those are high pressions one. (Actually i am not too sure about this, so don't believe me too much and correct me if I am wrong)

About the neon 2.4L I guess, that the neon already had a swap ( for the neon is easy) they just buy the swap kit and connect the harness and some other goodies (lucky Bast$%#) and FLY!!!

the 2.4L stratus is one of the clouds car. U can have from there.

talonator1488 Hey tito your right down the interstate from me

what do u mean with these?


Personal note:
Dude, I am not a technician ( I want to be a mechanical engineer) but i have been reading and researching for a couple of months about the 2.4L swap. Believe me it is a PITA but if somebody sell the SWAP KIT a half of the job will be vanished. That is what i am waiting for. As soon it goes out i am all N/A engine. If u want more info hit me a PM and let's see how can i help u related to the swap or something else.
These is why we are in these club we share info to make everything else simple.

( DAM# , i have to find my notes about the 2.4L swap )

Later, TITO

[SIZE=3]which vehicle is the 2.4L in. I am new to all of this so this may seem like a stupid question. But i want to stay N/T!!!!!!!!! [/SIZE]

 

[talonator1488]

Im goin back to the yard tommorow ill check up on those four door neons there was two of them one was burned. but the other had the complete 2.4 and it had the same forward facing exaust manifold as our 420a's. Tito, I meant that you are only an hour away from me your in daytona im in jacksonville. Im gonna go try to figure out these pm things.
As for the injectors my aspiration (no pun intended...LoL). Is to build a turboed,low boost, 200-260 horse streetracer/daily driver out of a 420a. Im welcome to suggestions-Im on a limited budget keep that in mind ive already located a stock 1g turbo, intercooler and injectors, for 100.00. Me and my friend are gonna build a kit from this.

 

[titogs95]

to 99rs:
dodge stratus 97-99
dodge caravan 96-99
chrysler seabring 96-98
Chrysler Cirrus 96-97
Plymouth Breeze 97-99
and maybe other cars.

About the pt-crusier i am not 100% sure

I am 100% sure that any neon came from factory with a 2.4L engine.

Dude, my recomendation is u r going to be turbo just rebuild the engine (maybe stroke it) and install a kit. be sure that the piston are low compression number 8.5:1. That will be easy and will match your low budget. But, if u want to go deep ( in troubles) so go ahead and do the swap. And u will be a twin brother of the dodge srt-4 2.4L car. Remeber our 420A has a lot of potential. and the eclipses looks really good already.

BTW whenever u get to the junkyard let me know if u see another cloud car. because here in daytona i didn't see any of those cars. Only one and was roasted as hell!!!!!!!

Anyway take it easy
I hope we can meet some day.

Later
Tito

Hey tito do you think I could get away with running 8-10 pounds of boost on 420A stock rods with reinforced 8.5:1 compression pistons? and do you think I could get my 230-240 horse out of that set up, possibly with nitrous?How durable are my stock rods anyway?... Who agrees that that blue talon on the tuners main page is sooooo sexy! , wish mine was looking that good!

are you looking at both nitrous and turbo at the same time? i wouldnt recomend it. our rods are very weak. 8-10psi would be pushing it, but then to add juice, thats just insane.

8-10 pounds of boost on a turbo (depending on which kit or turbo you go with) will put you at around 225hp. But you're going to need to upgrade fuel with that (injectors) and get something to manage with it (comes with the kit).

Nitrous + Boost on stock rods = :thumbdown

If you're going to upgrade the pistons, pay the extra money and do the rods too.

yes, save time and money(if you dont do it yourself) with the install.

i think our stock injectors can handle up to 10psi but a new fuel pump and injectors would be recomended

Dude i Do not have too much info about turbo!
so whatever they say!!!! ( rebuild the block very well!!!!! and u can do almost anithing)
It is all about the money

I am goin all N/A

There are no 2.4L Neons except SRT-4. The Neon owners that race their cars on the track, mainly did 2.4L Stratus bottom end swaps and used the DOHC cam heads off the Neon ACR's and R/T's. Then turboed them or stayed NA.

Dodge picked up on this trend and this is why they created the SRT-4 the way they did (2.4L).

ok a PT crusier block will work as well as above mentioned blocks; any years fine for PT.

To build an N/A:
either Crane 0016 cams & 10:5:1 compression and cai/header/exhaust or

2.4 block stroked to 2.7 liter at 11:1 or 12:5:1 compression (lower redline than a built 2.0L but who cares..youre NA you need the extra torque)
run 93 or 94 octane depending on where you live, and use Methanol/Water injection.
This will alow you to run pump gas and increase your octane so you dont have to buy race gas. (12:5:1 cr needs 110 octane)
A good site for this info is www.snowperformance.net (methanol/Water)
Crane 0018 cams or Crower Stage 3 cams (should not run 0018 cams with stock compression)
Race ported and polished head with all usual bells n whistles
long tube header
upgrade fuel pump and injectors
underdrive pulley
Extrude hone or sheet metal intake manifold
egt water temp, volt temp, oil pressure/temp, and air/fuel guage
Wideband unit (LM-1 FJO or Digitune etc)
cai/ 2.5" exhaust/ test pipe
Howell Automotive AF/X race ecu if your'e 97' . Do a search on ebay for 'reflashed 420a ecu' if youre other than 97'. same thing but 7800 redline limit instead of 8100. (+10 above stock timing from advanced timing fuel map and fuel curves-- total timing: 26 to 28, no speed limit cutoff, no need for downward 02 sensor)
metal headgasket
solid front motor mount, motor mount inserts
Retro-fit lsd or AMI or Phantom grip lsd ..in that order, you decide based on $.

Havent heard any 2gnts go this far expect for a guy who is still 2.0L on a 420a Eclipse, but is at 12:5: compression and plans on using custom Crane cams higher than 0018. He runs race gas. Otherwise, for a Neon , Ive heard of a guy who put down 320 to the wheels with custom Crane 0022 cams and a 2.4 Block NA. Drives it on the street too.

the good thing about running 10:5:1 cr , is you can still prolly try to run a turbo kit on it later on, provided you use a ignition box to retard timing , and a good stand alon unit like Accel , TEC 3, or Haltech or Megasquirt (which is the cheapest around $350 - do an ebay search)

Hey ""Initial DSM""
I have a question: If i have the 10.5:1 or 11:1 what fuel octane do i have to use?
I can not be using Methanol
I could be using 93 octane is not too much problem

And how many ponies do u think that setup will built? Even thought i think it is too much for me i want to go arround 200Hp N/A maybe 180WHP. I dunno if that is possible, YET!
I might be running some Nitrous to help the engine but that's it

Well thanks!
Tito

Yeah 93 octane should be fine. 11:1 is prolly really pushing it but its the limit i think on pump gas. I seen someone run a 15.9 with crower 2's & 10:5:1; but I know he can do 15.0 / 14.9 with practice. Stick with 0016 cams if you go 11:1 & if you dont have any fuel management system. Also get slighty bigger injectors and a walbro fuel pump. Methanol is cheap though so dont rule it out, it increases octane level and should be safer than propane injection.
Look up the Megasquirt unit as a cheap stand alone. Works really well for the price. AFC you can get away with, but this does so much more and theyre both around the same price.
Remember , high compression NA is harder to tune than standard turbo setup so do it right the 1st time.

Thanks for the info. It has been usefull!!

BTW doesn't sound crazy the part about my goals with these car?

no
Ive seen crazier.

imo, a 2.7L 11:1 cr , 0018 cams ported head NA with long tube header, sheet metal intake and 2.5" exhaust w/ test pipe & upgraded ecu & methanol injection would be the best scenario. The extra amount of torque the displacement would bring would benefit from the lack of boost in low & midrange.

n20 is just another for of boost imo.
