SRT4 In a 2g eclipse... can it be done? and whats involved?

[MitsubishiRS2g]

Hey, i think the subject line says it all but I have a 420a in my current car, all bone stock with 197,545 miles on it. Just barely has a whisp of smoke and thats only after about 20 minutes of driving. I want to do something no one really does and i couldnt think of any more insane idea than doing an Eclipse SRT4. Im a huge mopar fan and would love for this to be a possibility. I know the turbo and exhaust exits on the back side of the engine closer to the firewall on the SRT4. And im sure i would have to have a custom exhaust built (which isnt a problem since i work in a machine shop on the weekends) but what would i have to get in order to do this right besides the engine and tranny... ecu? wiring harness? ive only had my eclipse since November 11, 03 and i am determined to make this car insane. If it can be done, im gonna keep it stock besides CAI and a custom catback dual exhaust, but this is gonna be a show car so i can deal with the power loss from a dual exhaust. Let me know asap.

well since an srt-4 motor is basically the exact same motor that's currently in your car, only with larger displacement, you'd think you'd be set, but the motors sit backwards from each other, and the tranny is on the other side, so it'd be a lot of custom fabbing, a lot of headaches and more money than it's worth.

 

[MitsubishiRS2g]

well, see with the 420a engine, my transmission is on the Drivers side as is the tranny on the SRT4, so i thought that would be the most logical choice and its a dodge motor so you know youll never have major problems especially seeing as this car will be a show car, not a race car.

 

[Seattle GST]

yea, lots of work. And why would you want a dodge engine in a 2g? for about the same cost, you could get a stroker 2.3 4G63 running a FPgreen and I do believe that would be some deal faster and easier than a SRT-4 in a heavy 2g shell.

If mopar supports NASCAR, then I would shy away from using them as a source for products. . . I hear that new thing that's capturing the hearts of Americans, its taking the nation by storm. . . Technology. like independant rear suspension, disc brakes, and fuel injection. Both good things to have

 

[Cirus_93TSI]

it can be done, but its far more work then its worth if all your looking for is a faster car. you can put that engine in a crx if you wanted to custon fabricate everything, but what would be the point?

for the price, you could sell your car, buy one thats turbo, and buy a built engine and an aftermarket turbo and set up. it would be alot faster, and save you alot of downtime on your car

 

[Thomas91169]

everything would have to be custom. not saying it cant be done, but if youre asking how youre prolly in over youre head.

that being said, it would be easier to get a 4g63 and build that up into a 2.4 stroker, forged internals, and some huge ass turbo, then a shep built tranny. im thinking that it would be alot easier to drop that in than some neon engine, and prolly cheaper.

you can take 7 grand for the motor/upgrades/turbo/tranny and have alot of fun doing a custom project, and in the end have a 12 second car for 7 grand, or you could do what everyone else says and get one thats already turbo for 7 grand and still be stock running 15's.

 

[truECLIPSE]

it probably be cheaper if you just sold your car and bought an srt4, ok maybe not... sure you could probably custom make something that works for your car but would be throwing out a lot of $ too

 

[ACKERSON]

it would definitely not be worth it. The srt4 and the newer neons have very unique wiring, even the previous gen neons are having issues with the swap. There is a lot involved with wiring and the crossmember, tranny, suspension, removal of the whole dash assembly, etc, etc. Go to the neon forums and check it out. If you want turbo, it will be cheaper in the long run to sell your car to buy a gst or gsx.

 

[Catbox_95]

It's like you guys read the post Title and didn't pay any attention to what the original post was. Why an SRT4 engine? Because he's a huge Mopar fan. He already said he wanted something different, something no one has done, and it will remain pretty much stock so he's not looking for the best way to make his 2g fast, and it will be a show car so he wants unique.

That all being said, sorry I don't have an answer to the ORIGINAL post, I was just trying to get people back on track.

 

[IHeartTurbo]

Why would you want do this if your just making a show car?

Don't ever ask "why" about show cars. Ever.

I'm really not quite sure what is wrong with you people, so I cleaned up the original message so you can focus on it better.

Hell, it's annoying me so much I think I'm going to do some research on the subject and answer his questions myself! :laugh:

 

[Catbox_95]

Well said.

you pretty much want to swap a 2.4 for your 2.0. The head sets on oposite from your 2gnt to the neon. The wiring would be different and you'd have to figure away to get the ECU to work with your existing car. You'd have to fabricate motor mounts and figure out clearance issues. Not worth the hassle or the cost.


The real only difference between the engine you have now and the one in the srt4 is .4 liters. Just rebuild your current engine (bore/strock to increase displacement) and throw a turbo on for a fraction of the cost and 1000000 times less headaches.

 

[mntalon_05]

basically, by boring your 2.0 chrysler motor that's in your car, you have a 2.4 chrysler motor. the two motors share the same block, basically the same head, only I think the 2.4 has a beefier valve train and the naturally aspirated 2.4 has balance shafts, not sure about the srt-4. so by boring and adding a turbo, you have an srt-4 motor with a lot less cost, less problems, easier upgrading of the turbo and if you're already tearing the motor apart for the bore, you're probably gonna upgrade the internals. If you wanna do the srt thing, do all the above, and get the valve cover, if I remember right from the stratusphere forums, it bolts right up, but I suppose it'd be upside down on your car.

 

[Catbox_95]

Boring a 2.0 out to a 2.4? I don't think so. You need to stroke it to achieve that kind of increase in displacement. If you bore a 2.0 liter 40-over, which is about all you could comfortably go, you would have about a 2.06 liter.

 

[mntalon_05]

my bad, I meant to throw in a stroke with that bore. actually now that I think about it, the 2.4 might just be a stroked 2.0. I'll have to get back on the stratusphere.us or neons.org boards and do my research. I used to frequent the two sites a lot when I had my breeze.

 

[Dudeman]

Just do a search for a 2.4 swap.

You can use the bottom end off of a SRT-4 engine but you need the same head you have now, and a turbo kit for our 420a since the heads are opposite i.e. The exhaust manny/ turbo should be in front of the engine instead of like on the SRT-4, where they are behind the engine... I think, thats how it is with the regular neon 2.4 swap.

I myself bought an 01 2.4 block that was originally in an Dodge Caravan. I got Eagle H Beam Rods, .020 over Wiseco 8.8 to 1 pistons, Race Balanced Crank, ect ect and I now have a stronger block then the SRT-4 and slightly more cubic inches.

The major crap in dealing with the swap are; rewiring the injectors, advancing the CAS 90 degrees, fabbing up a passenger engine mount, notching out the oil pan or dropping the cross member if you don't want to deal with tig welding, fabbin up all new accessory brackets, using a pt cruiser alternator bracket, and a few more things, all of which are found in the archives of this site, and 2gnt.

I'm almost ready to drop in my engine. My rods finally came in, so we are able to send the weight of the rods/piston assemblies to a machinist so the crank can be balanced.

 

[ACKERSON]

You should go to the neon forums and do a search. on a previous gen neon you need to swap pretty much everything from the steering wheel forward to make it work. The wiring and electronics are completely different. So on your car it's going to be a nightmare. If you can find somebody to do the swap for you for under 8k not counting parst you are a lucky guy. I don't think you are aware of the cost of this swap. If you have that kind of money lying around you should head my way and I'll do it for you. Just search the neon forums.

 

[Masakari]

with enough money and time, anything is possible

 

[MyEclipse5]

I'm not sure if this was said already but the SRT-4 motor, and the Eclispe 420A are not the same. The SRT-4 has like the A850 or something like that. The old basic neon had the 420A.

 

[Catbox_95]

I went to the Autorama and saw a '66 Chevy pickup with a built LS1 and a 6-speed in it. That means he had to install an ECU, build wiring harnesses, build mounts, fabricate transmission mounts.... Damn, that can't be done! He should have just built a '66 Chevy carburated motor with a 3-speed automatic, like it came!

Hopefully you see my sarcasm here.

 

[Masakari]

The LS1 is a very popular powerplant for swapping...there are a million and one diffrent wirring harnesses/engine brackets... this idea is a complete retro fit and would be infintately harder then swapping in an LS1 into an old chevy pickup

 

[4g64GST]

if you are going for the WOW effect when I say go for it, As you can see you woud wow about everone that had posted so far, but remember WOW = big money. Yes it will be a costly and time consumming swap so be sure you have other transportation lined up for a few months.

Just sit down and make a list of what you need where you can get it and how much it will cost. then deside what you want to run (parts wise) and design and figure out how to put them together and how to wire them together.

and last but not least, expect alot of problems ever after you figure everything out.

why a srt-4 swap on to a 2gnt?
love mopar? go grab the srt-4, upgrade the turbo.. and few bolts on.. and own.
