Hello everyone! I’ve been in the Honda camp for some time now, performing swaps and doing engine builds, and have become interested in the Hyundai as a new platform for a project.

From the reading that I’ve done, it seems the Accent/Excel/Elantra are the preferred chassis’ for swapping….true/false?

What I’d first like to learn about, are the different chassis and engine codes used for various model years of the above platforms. I’ve seen codes such as X3, Alpha, Beta and Delta thrown around, and though the last 3 are engine codes, or rather, engines that Hyundai designed, I do not know to what models they belong. I’ve also seen that X3 is used for some Excel’s and Accent’s, so what does X3 really refer to?

I know a little bit about Mitsu motors, but how do you decode their lettering/number scheme? I’ve seen that the 4G15 is a 1.5l SOHC 8 valve used in the 89-92 Excel’s, but obviously the 4G63 is not a 6.3l, but I do know that was the predominate motor in the DSM’s.

What is the general consensus on swapping, if the motor was originally a Mistu, any Mitsu will swap in (same goes for Hyundai’s engines) or can you swap in an earlier model Mistu into the later generation Hyundai’s, or vice-versa?

Thanks in advance for your help.

Hi there...

I'm not exactly a motor swap expert, but I can fill in a few of the blanks for you.

First off, x3 is the platform code for the 1995-99 Accent. (In Australia, this car was still called the Excel, just so you know... they didn't adopt the Accent name until the 2000 model year). x1 refers to 86-89 Excels and x2 is the chassis code for 90-94 Excels.

The platform code for the 2000- current Accents is LC.

Alpha is the code name for the Accent's motor. It was actually first used in the 1993-95 Scoupe, and starting in 1995, was used inthe Accent.

The Beta is the 1.8 and 2.0 litre used in the 96-present Elantras and 4-cyl Tiburons.

The Delta is the 2.7 V6 used in the Sonata and the 3rd gen V6 Tiburon.

As far as motor swaps go, several people have swapped Betas into Accents.

The Excel, and earlier Elantras (92-95) are Mitsubishi based cars. The Excel came stock with the 4g15, and I can't recall the motor code for the Elantra... I know they came with a 1.6 or a 1.8, depending on trim.

The 4g63 is the motor code for the 2.0 litre that was used in the Talon/Eclipse/Laser/Galant/2000GTX. It came either as a N/A motor with 140 hp, or as a turbo motor with 190-200 hp. The N/A motor is referred to as the 4g63, and turbos are known as 4g63t.

The 4g63 can be swapped into the Excel and early Elantras as well as into earlier Sonatas.

Generally, swapping a Mitsu motor into a newer Hyundai or vice versa isn't really worth it, for a number of reasons.

The Mistu motors were oriented differently in the engine bay, with the motor on the driver's side, and the tranny on the passenger side. Hyundai's newer, homegrown, engines were reversed from that, with the motor on the passenger side and the tranny on the driver's side. That makes it more worthwhile to keep the Mitsu motor swaps limited to older Hyundais, as they don't require as much custom work for the motor to fit properly.

As well, as far as Accent swaps go, the Beta is a perfect candidate... it gives a significant power increase, even if you leave it N/A; it requires little custom work to make it fit; and even though the Beta has never been sold as a turbo motor (unlike the 4g63), the Beta is a tough motor, with a strong block, and can be turboed reliably.

If I were you, I would buy an x3 Accent, (so far, I think there have been many more x3 Beta swaps than there have been with the newer LC) and find a good quality Beta motor (they can be found on e-bay fairly regularly) and do that swap. The Beta can be swapped in with the Beta transmission OR it can be used with the Accent transmission too, if you prefer.

Many other Tiburon/Elantra piece fit the x3 Accent too... the front brakes are one example I can think of right now.

That's pretty much the extent of my knowledge as far as this goes... I now open the floor to other members... particularly Rudy and 99mini, two members who have done the swap successfully. Due to an accident, Rudy's car was sadly written off shortly after his swap was done (it was a sad day here when we found out), but as far as I know, 99mini's car is still going strong. I'm sure they, and others (TurboHyundai, who has a GORGEOUS older Sonata with a 4g63t) will be able to offer some advice.


:D

wow, chris you pretty much covered it all i can't really think of anything other than:

2000-20002 accents are LC's and 2003+ are LC2.

GK is the chassis code for 2003+ Tiburons

RD is for 1997-2001 Tiburons.

Early elantras are known as J1 and J2 respectively. the 2001+ Elantra's are XD

The newer Tiburon's and elantra's have beta2 engines which have a different cam profile.

any other questions feel free to ask. i'll make this post sticky.

Excellent information - Thanks a lot.

So it would seem the Beta1 engine from the 97-01 Tiburons into a 95-99 X3 Accent is the hot ticket, and now after re-reading the Grocery List thread ( http://www.hyundaiperformance.com/forums/topic.php?t=21181 ) it makes a lot more sense.

So now, where can I find engine information on the Beta1, such as cam profiles, bore, stroke, rod length, compression ratio, open/closed deck....that sort of thing?

EDIT: Found it at ( http://www.hmaservice.com ). What a gem that site is!

Can these engines be procured through the dealership at a 'relatively' low cost, under 5k or so? I'm not really a big e-bay fan.

And a Q about the axle and tranny mount situation: I've never shortened axles before (but am technically/mechanically inclined), is there a how-to somewhere detailing this, or this there a totally stock alternative? As far as the mounts go, you say one will have to be professionally done, what do you mean by that? And as far as the tranny mount goes when using a Tiburon tranny, is this a stock piece, or another professional piece?

EDIT 2nd: According to this thread ( http://www.hyundaiperformance.com/forums/topic.php?t=20565 ) it would seem that using the Accent tranny allows use of the Accent axles as well, however, one thing they make mention of are the mounts, and that it seems the 97-99 are better candidates than the 95-96.

What other little odd-n-ends are there between the 95-99 Accents that would make one model year (or range) better suited to this Beta1 swap?

just to clear things up:

n/a eclipses are powered by a chrysler based 420A motor with a mitsu designed head(this is the motor found in the 95-99 neon but with a chrysler head)

the na 4cyl mitsu in hyundais is the 2.4l 4g64 this is the same motor in the eclipse spyder/chrysler sebring

as far as i know if they never brought a non turbo 4g63 over here and i may be wrong but i dont think tha exsists?

ps: what can be swapped into an x1 excel?

thanks

Hello Guys:

This is my first time here and I woul pretty much be doing the engine swap for the Accent. I am thinking about buying a new accent tree door and preparing the car as strictly racing car in my country. What do you think about the three door model?

Thanks,

uh alpha came in two version: sohc is alpha I and dohc is a Alpha II

edit: having tibby 2,0L engine in the hood is fun :eek: i spanked a tibby 2,0L on my accent ;) well spank is maybe strong word.. i won him through 1 and 2 gear and 3 he was no more :evil: but get yourself a tibby gearbox.. the accent before new model have gearbox that are build on colt ´86 blueprint and their gearbox are trouble... mine broke then i was cruizing on 80 km/h and just driving up a hill = no speeding or shifting , the car just slow down and nothing happen in gear thing :hmmm: , every part was broken (2 months after i add tibby motor to my accent)

to clear up about the mitsubishi enginges, the 1G eclipse/talon/laser were available with a turbo 4G63 or n/a 4G63 and the 2G eclipse/talon were available with a turbo 4G63 or a n/a chrysler 2.0l

Brand new Engine from teh dealer will cost you 3k but i am not sure if that is with tranny or not and if not price will not go over 4k so it is in price range you wanted(not to exceed 5k)

from wath i was told by ppl that have done the swap 2 our of three do not need to be modified(front engine mount and drivers side. but passenger side mount needs to me modified or costum made.


another thing. i dont think anyone has mentioned that 1.5L alphas come with both Dohc/SOHc if iam not mistanken 97 GT accent has 1.5 Dual overhead cam.

also Beta 2(01 elantra+ and 03tib+) engines are not only different cam profile but they are also MAP based, so as current 1.6 DOHC Alpha2 which comes in 01+LCs and LC2s
(all other accents are MAF based including 1.5 DOHC alpha2 from first gen accents)

EEEEEEEEEEEEEEE! Wrong! 2nd gen N/A DSM's share a 100% Chrylser designed a420 DOHC engine with the Neon. If anything the head is more like the Lotus designed cylinder head Dodge offered on the 224hp Turbo 3 Spirit R/T

All on www.allpar.com

Don't guess at it, you would be all over me if I got somebody about Hyundais wrong...

Ok, I have been wondering....

How hard would it be to swap a 3.5L Delta into the 2003 Tiburon?

eh... wrong for both of you.. I used to own a 2nd gen RS eclipse..

here you go, for the 2nd gen (95-99) eclipses

RS & GS had a 2.0L chrystler 420a
GS Spyder had a non-turbo 4g64 2.4l motor
GS-T, GS-X and GS-T Spyder had a 4G63-t

I know for a fact that the GS Spyder is the oddball.. it does NOT have the 420a in it. There were several aftermarket turbo's (hahn racecraft, star performance) for the RS and GS but they would NOT fit on the GS Spyder.
