engine swap

[protetype]

Hey guys,

I wanted some advise or info about swapping in a pt cruiser turbo engine or dodge neon srt 4 engine in my 95 eclipse. My engine is shot. I've found info on doing the swap but i was wondering what everyone thought or had any advise. Which one would be best the pt cruiser turbo or srt-4 motor. thanks

if your going to spend the money you should get a rebuilt 420a non turbo motor and get the aftermarket turbo which comes with everything you need fro the conversion from nonturbo to turbo for the same price your going to pay for one of those engines and someone to due the required mods for the conversion also i woujld go with hahnsracecraft their probably the best for the money

dont make laugh fo..l. Please do some reasearch vertiay. I dont know where to start correcting you, its like a baby in a candy store. YOu dont know sh......t. please realize that all turbo motors are built just for that. A turbo motor is made to take more psi. The oiling system is upgraded, and in this case squirters are added to the interior of the block, Cylinder walls are thiker, ...... Please i just couldnt help myself. IF anyone else reads this please, all i am asking for is for your opinion on pt cruiser engine versus the Neon SRT4 engine. These engines are baisicly the same just another version of the 420a that can "emphasis on CAN" take the PSI of a forced induction system.. Which one of these two is easier to swap, and which has the best valve train compotents.

SRT-4 and PT turbo engines are backwards compared to ours. No they wont fit. Unless you do some a ton of custom work that will cost $$$$ Engine swapping in a 2gnt never works out well. I would just build the engine you have. It will be cheaper and faster .

protetype, you should do some more research before you trash talk someone who gives you good advice.

As already stated, just because they share the same engine code doesn't mean they have very much in common. The neon/pt cruiser blocks are mounted backwards compared to eclipse/talon 420a. As in, exhaust mani is on the firewall side and intake mani is toward the front of the car.

Then let's go into the fact that the ecu, engine harness, tranny, motor mounts, and a whole ton of other stuff won't fit and will have to be swapped/modified/customized.

If you're gonna go all custom, then props to you, but for that same amount of time and effort, you could have just built up your engine and turbo'd it.

look guys i had a bad day when i wrote that repply. I hope i dint piss anyone off. I am just a little pissed with my car.
So far all i know about the swap is
the lotus head that comes in the eclipse is interchangable with most dodge engines like neon2.0dohc motor, the 2.4ldohc motor that comes in stratus and various mini vans.
When switchin the heads new cams and gears are needed.
the spark controll has to be modified
the injectors have to be switched
most 5sp trans are interchangeable
most modualar and nonmodular clutches are also interchangable
and that the auto throtle body from the auto neon is 5mm biger and also fits our cars.
What i am not sure on is wether i need new mounts if i have a 1995 re eclipse. the 2gnt aluminum engine mouts
or wether i need to upgrade me computer.

I know that it seems weird that i want to swap instead of build up but i just blew my engine to S.... Lets just say its in a much beter place or places..
I dont want to start again with the 2.0 because it dint give me the torque i wanted. Also a 2.4l engine swap is just a bit more $ then the 2.0 but with much petential, and a 2.4l turbo plant is avaiable from the new pt cruisers and the srt4 this i think would dominate any 4g built to the same specification. I'd apreciate any advice on this process.

Uhh..not sure if youre really listening to the advice given to you so far, but yeah, SRT-4 or PT turbo cruiser engine will be hella hard to fit into an eclipse. Im working on a talon with a 2.4 dodge stratus bottom end swap already in so in about a month or 2 i should be done. Since you seem to have some knowledge of the Lotus history, you would know that our heads flow fine if not better than 4G63 heads from stock, so no need in doing the enormous custom swap to put the pt/srt-4 head on; just keep the stocker. I would opt for getting a 2001 PT cruiser non turbo block and shipping it off to VT engines to get rebuilt for turbo. I have one lying around for my eclipse that ive been meaning to do as well..

Where to start...

Well, to get the main question out of the way..

They're the same engine. 2.4L DOHC Turbo 16V I4. Neither swap is "easier" to do, due to the fact (already been stated) that they are backwards and need MAJOR fabrication to be successful.

Now...

1) Lotus did not build the head, they "contributed" to the design. There is a link somewhere on this board or on 2GNT.com stating this.

2)They (SRT-4/PTturbo & 2GNT) do not share the same engine code, platform maybe.

Not trying to bash, I would like to see flow charts for this statement.

 

[Initial DSM]

I would like to see them too, but I know Lotus didnt make the head; actually I discussed this in several other threads to people who though otherwise. It was a failed project that Lotus dropped after they designed the Spirit R/T and Dyatona R/T. Back when i owned a 4G63, I would argue this with a friend of mine whos dad is a writer for several car magazines, and he recalls that Chrysler took over several of Lotus' ideas for the head when they made the neon and eclipse 420a etc in 95'. It was his opinion as well that the head would outflow the 4G63 head.

OK if i doo get a 2.4l engine from a stratus or...... will it be easier. I know that alot of people have been saying that if i can get my hands on a 2000+ pt cruiser then the swap is going to be simpler, is this true. Ohh, and how much wil it cost to get a N/T block prepted for turbo aplications. My ideas was to get a
1. 2.4l turbo block only, then put my stock head on that
2. add some extreme cams so that the 2.4l can breath
3. doo the needed electrical work
4. get the ecu reworked to acomedate for the biger fuel demand
5. Add a biger throtle body from a jeep
6. install some 600+ cc injectors along with a 100psi fuel pump and regulator.
7. up the spark on the coil
8. take the car down to L.A. to a company that can custum make some tubular turbo headers for the car.
9. to start of with a td04 turbo
10. a good intercooler and radiator
.
But my only problem is that i am not sure witch block to put
i read in a magazine that the 2.4l turbo neon engine has squirters and thicker silinder walls. The oil and wall diferences is what makes this engine so wausome. Is this true, can i just use a build 2.4l and get the same performance from it??
If anyone knows please let me knwo......

some issues with swapping to a 2.4 are the pass mount has to be custom fab'd, injectors have to be rewired, oil pan has to be molested for the exhaust to run underneath it, hood clearance is a problem due to the extra inch of deck height on the 2.4, and the crank timing has to be fixed also. just a couple things off the top of my head, hope it helps.....trust

the 420a motor is already higher compression than the 4g63, it's also stronger more reliable and can take twice the beating of a 4g63 so FYI ask someone who's worked on both motors that has a degree and you'll see your wrong. Also the hans racecraft eclipse is a RS that runs 8.8 at 161 go to the site if you think i'm lying. The 420a is capable of putting out more horse than the 4g63. come on man whats with you

I hope you're not reffering to a stock 420a block vs stock 4G63 block. I'm gonna assume you meant a rebuilt 420a, but even still, I would never go as far as saying its twice as strong as a 4G63, more like they'd both be evened up as a block is a block is a block once both are upgraded with internals. And its not capable of putting out more hp than the 4G63 ; again research before you make a fool out of yourself.

 

[vertiay]

4G63 compression stock is 8.4:1
420A compression stock is 9.5:1
I have a chilton right here with all the specs of both motors and hp for hp a 4g63 will detonate even properly tuned faster than the 420a. It's been proven in numerous articles. Thats why the lancer evo's use the reverse setup of the 4g63 for their cars because the setup by design is better than the eclipse 4g63 motor, the same design as the 420a.
A stock 4g63 is slower than a stock 420a with a stock spec turbo kit. If you think i'm wrong post a thread see what everyone thinks

 

[TRUSTEDONE2003]

i put in a request for a tech article about this swap. hopefully we can aquire some interest...trust

 

[Defiant]

Good.

Now, take the mutual shoe-pissing to PMs, or better, just knock it the hell off altogether.
