Me and my friends were talking and a arguement came up between some of my friends one of them were saying that non turbo dsm's have the same motor as a regular neon. It had me thinking is this true or is it a dang lie. :dsm:
 
Not the 90-94 DSM's. They had the 4G63 motor but was not turbocharged, or the 1.8L, but that was not a neon motor. The 95-99 N/T's however did use the same 2.0L engine as the Neon RT's. The other non turbo engine was the 2G spyder, but that was a 2.4L and was not used in the neon's.
 
hey thanks for clearing that up for me
 
OMFG!!!!!!
The 2G non turbo motor IS NOT the same as the NEON motor!!!!!!
The 2G turbo motor is the same as the 1G turbo and non turbo 2.0L motor.
If you think that a 2G non turbo (420A) and a neon have the same motor... park them side by side and look closely at the intake and the exahust. OMG see anything wrong?!?!?!?
Like maybe the fact that they are switched?!?!?!?
 
That's because the head is different. I'm almost positive it's just the block that's the same. Either way, it doesn't matter, the 420a sucks.

Hmmm.....the 2G turbo motor is absolutely not the same as the 1G turbo motor in many, many ways. Take for example that one is a 6 bolt and heeeeey one's a 7 bolt motor. As far as the way the heads are positioned on a 2G non turbo and a neon, who gives a sh!t. It's still a 420A.
 
Actually, the onlt difference between a 1G 4G63T and a 2G 4G63T is the better rods in the 2g, The very restrictive head on the 2G, the tiny little throttle body on the 2g, and the tiny little turbo on the 2G.
Actually, speaking about 6 bolt and 7 bolt..... all of the late 1Gs are 7 bolt also.... not just the 2G's! :cool:
 
Moved so that the N/T guys can set it straight.
 
Appearance wise, the Neon 2.0 and the 420a aren't the same. I have never actually taken a look at a Neon's engine in detail to know how similar/same they even are. I believe the 4 cylinder Avenger used the 420a but like the Neon, I haven't actually checked it out.

The Motor in the 4 cyl avenger is the 420a, in fact its identical, nothing is even changed around a bit, hell, even the inside of the avenger is the same as the 2g eclipse
 
same engine bascially (95-99 n/t) except that the intake goes through the front and exhaust through the rear on the neon. i read once that the neon engine has less HP but more torque. the neon is a shiot car the 420a power plant is actually pretty good.

o kso your tellign me then stock puney 2g rods are better then the 1g big rods. if this is the case why do the stock 1g big rods hold 450hp?

They are all 420A's, specs are as follows

Eclipse 420A
HP - 140
Torque - 130

Sebring 420A
HP - 140
Torque - 130

Neon 420A
HP - 150
Torque - 133

Avenger 420A
HP - 140
Torque - 130

The Eclipse, Avenger and Sebring share the exact same engine while the neon has 10 more HP and 3 more ft/lbs of torque, I read somewhere what exactly they did to the Neon's 420A to give it the small extra power.

Are you sure because I beat a Neon with my Eclipse GS before I did any mods what so ever

yes it is, the engine code for a neon is the 420a, whether it be the dohc 420a or sohc 420a in the neon, its still got 420a for the engine code
 
These guys who say "the 420a sucks"- I'd like to know what you're comparing it to. True that the 4G63T is a monster, but most of that is out of necessity in making it live under a turbo. That it does at all, let alone so well is another chapter in automotive history.

Just a tidbit: when the Neon came out, it was the highest specific-output engine that Chrysler had ever made. Including the BFD Hemis of the fifties and sixties.

Go out and learn more. It may make you sound a bit less stupid.

If DSM hadn't made the jump to the GS-T, -X, RS and TSi/AWD, the N/A Eclipse and its stablemates would have taken a place in the record as Really Good Cars, overshadowed only by the likes of the twice-as-expensive Zs, RX-7s, Supras and beyond.

Now, nigh on half-a-decade into obsolescence, the rest of the affordable-automotive world is only just starting to supass the performance level set by the "deluxe" DSMs.

Besides that, some of us don't like it when someone tries to give our little brothers any shit.

the neon motor does to have the same engine code its a 420A like ours, but its backwards from ours, and that makes it where you cant interchange pars :thumbdown but I read that chryslers quotes for neons 150 hp and 3 lbs of torque are a little over raited, thats why you cant find any information on how they got more hp and torque out of the same engine :D

Yeah im 100% sure about those specs.

I read somewhere about how they got more hp out of the neon, forced, or variable indicuction, or something was a step up from the Eclipse 420A.
