New to Hyundai... engine ID code?

[NOFX]

So, I foudn this forum tryign to help out a guy that's on my regular forum for Hondas. Anyway, he has a 2005 Elantra in the US. He's contimplating selling it and buying a Civic, granted that his father allows him to, but I have some questions regarding his current platform, the Elantra, before I give ihm any advice. (Yes, I don't like to be bias on the issue even though I have a Honda myself.)

So, first question... Can anyone tell me the engine identification code that the Elantra has? I'm not sure if it might be stamped on his block in a certain place like my Honda has. I can look up specs and such for it after getting the code, but I can't find out what code it is besides that it's a 2.0L I4.

It seems that this other member has done some research on what might be possible for modifying his Elantra, but he claims that the prices of said parts are roughtly twice as much as for a comparible Civic. On top of that I'm not sure how easy modifications might be for his car.

Someone else in the thread on the other site also asked if he has the 4G63. Now, no offense meant to any Elantra owners here, but I'm finding it difficult to believe that his '05 does have that motor.

Could anyone please spread some light on this for me? Thanks. :)

I do know that the beta2 engine is designated as G4GCX, but i could be wrong

Well, that's a help so far. A quick search sent me here:

:) Thanks!

October 2003 to present
Type: 2.0 DOHC HVT
Capacity: 1,975 cc
Power: 105kw (141hp)
Designation: G4GCX (Beta II)

what more do you want to know? Yes, modifying these cars is more expensive than a honda, there are less of us and more of you who do modding. Anything else, just ask.

Well, I'm going to see if he mentions anything else he might be interested in, but I do think that there is a good chance he'd be interested in some of the common things that people do to Civics (since the site he posts on that I do too, ClubCivic.com focuses on the Civic chassis).

So how about:
Suspension (we usually lower them for looks and performance)
"JDM" Parts (I'm not sure how much they might be different for Hyundais)
Rear disc conversions (how easy, price, donar vehicles?)
Engine swap (viable donars, ease, again expense)
Exhuats systems
Header/Exhaust manifold
Intake manifolds
Forced Induction

Basically... the basics lol. I'm not sure what the best route might be with these type of motors (for example, some Honda I4s respond better to supercharging, though the majority respond best to turbocharging).

Thanks for any help you might give me. I don't know a lot about Hyundais at all... so I'm sorry if I'm asking way noobish questions.

you can get kits to lower xd's, springtech ect. also tiburon 19.2 rear sway bars are nice upgrade

"JDM" Parts (I'm not sure how much they might be different for Hyundais)

KDM parts are not so plentiful as JDM, check related links above for elantra/avante xd

Rear disc conversions (how easy, price, donar vehicles?)
All xd hatchbacks have rear disk brakes as so do gt sedans, there is a DIY on somewhere on here i think

Engine swap (viable donars, ease, again expense)
not worth the expense, they do swap 2.7l tiburon engines in over in korea, i have seen pics, but no one has here, that I know of

Exhuats systems

you can get headers, cat-back, whole exhausts ect. for xd's

Header/Exhaust manifold

see above

Intake manifolds

check related links above

Forced Induction

you can turbocharge,which will probably provides more power, or supercharge, both by alpine developments

Thanks for any help you might give me. I don't know a lot about Hyundais at all... so I'm sorry if I'm asking way noobish questions.

wait... NOFX? is this amy by any chance?

now to be helpful

check out this sticky a very intelligent guy made ;)http://www.elantraxd.com/forums/showthread.php?t=13022

"JDM" Parts (I'm not sure how much they might be different for Hyundais)

theres certain "KDM" parts that can be found on sites like kspec and dreamak4u (i think thats how the second one is spelled)

Rear disc conversions (how easy, price, donar vehicles?)
donar car would be any 01-06 elantra with rear discs. best bet would be to find in a junkyard if at all possible

Engine swap (viable donars, ease, again expense)
no. nothing is going to drop right in so really not worth the effort IMO

Exhuats systems
you can buy bolts on but they are way overpriced. find an exhaust shop to make you a custom 2.25" mandrel bent exhaust and buy a muffler that you want on it. comes out to prob about 200 when done.

Header/Exhaust manifold
hotshot, evofusion, sharkracing, OBX. either one you'll have to relocate a bung for at least one o2 sensor.

Intake manifolds
i only know of one offered. thats the airram on www.kspec.com. but i don't think it'll work on the xd2s because those are set up for map sensors. i guess you could just plug it but ehhhhhh kinda sketch to me.

Forced Induction
www.alpine-developments.us

only company that makes a bolton turbocharger system. this engine respsonses very well to turbos. some good headwork yeilds VERY good results since the exhaust side on the head is shoddy at best.

Oh noes! I've been found out! :P

lol i thought so. when you mentioned CC i knew it had to be you.

As for the 4g63... it was swappable into older (pre-96) Elantras because back then they shared a lot of technology with the Mistus. Same goes for older Sonatas and Excels.

Beat me to it.

The 4G63 is a Mitsubishi motor (Eclipse) and Hyundai used the Mitsubishi drivetrain from 86-94. The 92- pre 96 Elantra I think had the 4G15 engine and the 4G63 could easily be used in the car. From 96-00 the Beta 1 was used, either the 1.8 or the 2.0 liter. 2001 had the beta 2 (an upgrade to the beta 1) and the same engine, although updated with a revised head that has the CVVT unit and a MAF sensor (instead of a MAP sensor as with the 01-03 cars).

The only issue (difference) is Honda detunes their engines and Hyundai does not. It is harder to gain significant hp and torque with the typical mods done to the car (Hyundai). You won't see 10-15 hp gains, maybe 2-3 at the most. The ECU is the bottle-neck and will revert the engine as close to stock as possible. People have tried aftermarket tuners, but the ECU has the habit of overriding those settings after a couple drive cycles and reverts the custom settings back to stock.

"Someone else in the thread on the other site also asked if he has the 4G63. Now, no offense meant to any Elantra owners here, but I'm finding it difficult to believe that his '05 does have that motor."

I not sure for the relationship with the 4g63 engine with the beta II engines. People that work a lot in race track with those engines said that the block is almost the same (based on). The head is the big difference but still the exhaust manifolds will fit with some mods (I think this is on BETA I head).

I was surprised when I went to the dealership to buy the rear cranckshaft seal (the one that goes in the flywheel) they gave me an Mitsubishi OEM 4g63 engine seal.......... :confused: Oh Yeah! And it was exactly the same.

DSM forrums will help a lot on this since they use Hyundais 2.4 sonata blocks to build badass strocker engines (sort of what honda guys do switching heads and blocks).

Maybe this has something to do with the universal engine Dodge, Mitsus, Hyundais carry or are planning to carry (I'm not that well informed). Whoever have more reliable info on this can share it with us.
