8G 5 speed hyundai sonata swap.

[Exhaust power]

Ok so i basically got the whole swap done and its not so difficult.

heres the parts list.

99-05 hyundai sonata/01-06 kia optima 2.4 manual
"M/T starter"
flywheel bolts M/T only
Transmission & mount
slave/master cylinder
flywheel/clutch
clutch pedal
floor shifter & cables
rear mount adapter plate (which can be taken off the automatic)
reverse solenoid plug
3g brake pedal

heres the modifications
1)transmission mount.


In this picture i had to to cut the sides off where the bolt slides through. make sure to cut right next to the rubber .reason to cut because they were to long and wouldnt fit inside the mount holder on the galant.

2) remove the transmission mount adapter plate. this will correct the alignment of the transmission sitting in the engine bay.

3) The holes on the transmission wont line up with the mount. so i had to cut slots on the 2 top holes of the mount.

4) Take the rear mount adapter plate and arm off of the automatic tranny.And install it on the sonata.

5)The rear holes on the floor shifter wont line up. easy fix is to drill 2 holes . install a bolt up top and a nut at the bottom.

01-04 SANTA FE m/t 2.4 options.

since the santa fe shares alot of the same parts with research i was able to find these.

1)single plain flywheel :
The good: very cheap compared to dual plain.
lighter.
The bad: alittle harsher when engaging compared to a dual plain.
I bought mine off of ebay for 110$.http://stores.ebay.com/Car-Parts-Discount__W0QQ_sidZ57831298?_nkw=santa+fe+flywheel&submit=Search

2)starter: santa fe and sonata shares the same starter.( make sure its a manual starter!)

3g eclipse/galant options
1) you can use a eclipse brake pedal.

2)I recommend changing the axle seal to a eclipse or galant

The things you should know
1)The part of the cables that gets bolted to the fire wall isn't as big as the galants so it just goes through kind of easy. easy fix is to take the plate of the galant cables and put it on the sonatas.

*2)getting the top bolt in to the clutch pedal is pretty hard. I basically got the 2 nuts(for the master cylinder and clutch pedal stud) on the pedal like half way so i can turn the pedal for that top bolt could line up with the hole. take your time you'll need that top bolt for clearance since the pedal will sit too close to the floor.

*3)make sure you adjust your clutch pedal and rod out as much as possible. the pedal should come out a little further then your brake pedal. I used the eclipse fork to push the pedal out further.
http://i71.photobucket.com/albums/i135/t-sire/tranny%20swap/Photo643.jpg I also cut out the clutch saftey switch nut to give it more clearance which isnt required.

*4)you have to remove your pilot bearing. I used the tissue method to get it out. the first time ever i simply yanked it out but this time it was tough to get out.http://i71.photobucket.com/albums/i135/t-sire/tranny%20swap/Photo629.jpg

*5) when you install your sonata transmission turn the throw out bearing rod counter clock wise . you'll know when the throw out bearing is properly seated cause you wont be able to turn clock wise easy. only do this when the transmission is bolted to the engine. In this picture its the rod that the slave arm is on.http://i71.photobucket.com/albums/i135/t-sire/tranny%20swap/Photo645.jpg

6) make sure if your using a sonata mount use the rubber spacer. You need to squeeze them in there bending the mount arm might help out. This will stop the vibration noise. The rubber spacer that came off the auto will fit well.

This tranny ratio is good for s 6.5-7k redline n/a set up wich is good for me.

[Galantman03]

hmmmm, i wouldn't trust the cut mount man.... i wouldn't want to be driving and then have it break all the way while driving it hard or canyon carving lol, idk IMO i would get the right mount... other than that looks good, keep it up! i'm curious to see if it works

[Exhaust power]

you really think that would snap? what is the right mount since you asked?

I forgot to say the swap is done and im driving it all ready . That mount should of broke on my first 4k drop lol . I just need to fix a small leak from the axle hopefully its just the seals and then ill be basically100% done.

[Exhaust power]

Thats all im done .

If you think something is missing you can ask.

[OMEGA PHX]

Total Cost of the swap??

[Exhaust power]

would of cost me under 300 but i had to make all the mistakes of buying other parts so lets say around 500$ for me.

hmm maybe the mount is ok then lol... maybe jb welds around it.. idk lol nice work. so everything fits? how does it shift? like difficult?

[Exhaust power]

Im going to put washers on the 2 top bolts.

and shifting is all right.Its kind of a notchy shift feeling .one of my shifter cable has a slight bend in it(my fault) so it doesnt auto center when i drag the knob to the left making 3rd gear kind of weird.shifting will get better after i bleed the clutch some more though .

[Exhaust power]

price list. If i would of got every thing straight from the junk yard "harrys u-pull it".
http://wegotused.com/prices.htm
M/T starter" -16.40 $
Transmission & mount & clutch- 87$ (they dont charge mount and clutch with tranny)
slave/master cylinder -24.70$
flywheel- 20.40$
clutch pedal/brake-10.70
floor shifter & cables-17.40
reverse solenoid plug-(with the tranny)

159.2 plus tax so around 180$ thats what they charge me when i had every thing except flywheel.

since i didnt buy a used flywheel i bought a new one for
single plain flywheel- 115$ ish
starter-90$
flywheel bolts-24$ ish including 2 clutch bolts i lost.
gear oil about-12$

so i spent about 400$ bucks plus on this swap. then the mistakes
3g flywheel and clutch 90$ used
a/t sonata starter (doesnt work with swap)- 34$

so about 524$+ with mistakes.

[Exhaust power]

Up date

[Exhaust power]

updated swap is not advised.

[dGALANTc]

just curious why so ill advised? still leaking or???

[Stewi]

What you should do at this point is take your stock galant axle and the sonata axle to an axle rebuilding shop. Have them measure the INNER CV joint on both axles, if they are the same size (diameter and length) or very very very very very close to the same size, swap the inner CV from the sonata into the galant axle. This way the hub side CV (outer) will still be compatible. This should be fairly cheap to do as well, probably less than $100 for both. Dont give up yet, you made it 95% of the way, keep your head up and keep going. If it works the reward will be worth it, if it doesnt work, you can really step back and say you tried "everything" Let us know how it goes.

It has a small leak but a 100% complete swap shouldnt have any leak. i just dont find that reliable or good looking.

This is where i stopped at. the galants bearing is on the left and the sonatas is on the right(in the pic VVV). The galants ID where the splines go are just a little to small compared to the sonatas. And also the roller bearings have a smaller OD. Im not sure about the ID of the roller bearing, i tried swapping them over but the galant has a different looking retaining clip(sonata has a snap ring) which i have no clue how to remove.


http://img191.imageshack.us/img191/4272/photo699w.jpg (http://img191.imageshack.us/i/photo699w.jpg/)

other options
I wanted to swap the "hub ends of the axle" around but im going to have to research how to remove that end.

so my other options were to swap the sonatas "front hub/studs/splines/" over to the galants. if thats possible seeing that the sonata is 4 lug i might have to experimant with there xg300 which is 5 lug. but that would mean using a sonata full left cv which is about a half inch bigger i dont know if that'll introduce anymore problems.

heres some pictures for reference.
The galants on the left sonata on the right.(outer/hub)
The spline in the sonata are bigger.
http://img842.imageshack.us/img842/9219/photo690.jpg (http://img842.imageshack.us/i/photo690.jpg/)

Inner/transmission)
galant(bottom) sonata(top)

going from left to right.
The OD of the axle housing is bigger on the sonata.
The OD of the axle which sits on the transmission bearing i believe is a tad bigger but im not a 100% because it fits in the galants auto tranny.
This is where the leak might be coming from. If you look closely to the splines in the sonata it is a bit longer i dont know if that would help seal the transmission though.

http://img88.imageshack.us/img88/3550/photo688.jpg (http://img88.imageshack.us/i/photo688.jpg/)

also I changed my axle seal but the out side of the seal has a slight bend from hitting it with a hammer(dumb mistake) would this have a influence on the leak?

[Stewi]

Do me a favor and measure the HUB side splines of the axle, I need to know the # of splines and an accurate diameter measurement. Im wondering if the sonata spline size/count is the same as the EVO because the EVO stuff is a little bigger than the 8g stuff too. If thats the case, assuming axle length is correct, if would be as easy as swapping in some EVO knuckles and hubs which can be had used over on Evom for about $200 sometimes less.

yes it can cause problems if the seal is damaged one bit.

[Exhaust power]

I changed the axle seal again and i dont see any leakage anymore. I end up using my left side axle seal; but when i first got both sides and compared them they looked identical.
but its funny that the driver side axle never leaked but the passenger did. but any problem seems fixed so far.

now i have a whine in 1,2 gear . could it be because my gears grinded down some? I know i grinded the hell out going into 2 gear one time. Or differential(hopefully not)?

[Exhaust power]

Put on almost 4k no problems. I will need a new master cylinder, IS seal (I think) and a clutch though. But no real/big problems at all.

[DTP]

Any updates?

[Exhaust power]

like what? trannys been in the car for almost 2 years running fine. About to swap in my second tranny in the spring since i experimented/learned on this one. Everything there is to know is stated in the first post. The rest can be ignored.

Okay cool. I'm just exploring options for the future. You never know with the auto

[Laidback8g]

can i get away with using a eclipse shifter or a evo shifter ? and what about the cables? can i also use 3g cables?

[Laidback8g]

Im also interested in this swap, because looking at the prices out here i can buy that transmission for 475 on car-part.com

[Exhaust power]

The floor shifter wont hold the sonatas cables. Im not 100% if the eclipse cable is long enough or too long etc to mount to the tranny and back. I would experiment but im done with experimenting lol

True

One tool you need to use a lot is a disc grinder of some sort

[xgingerbreadmanx]

Question. I recall reading on another forum about this same swap and it stated that the shifting is different. It is push style intsead of pull or vice versa. So as i understand it 2nd is in 1st and 1st is in 2nd and so fourth.

[Black8GV6]

What? push or pull is how the Throw Out Bearing and Pressure Plate interact.

[QnzMostWanted]

thats why he turned the TOB rod counter clockwise to address this issue

[xgingerbreadmanx]

aaahhhhhh. Thats what i thought but then i read this....http://www.club3g.com/forum/3g-eclipse-rs-gs-specific/124199-hyundai-sonata-manual-swap-cheap-alternative.html

VTECH Killer is talking about a kit to convert. I just wanted to make sure i was understanding all of this.

[Exhaust power]

Every thing on that 3g forum is speculation. Yes it is a pull style clutch thats it. If your taking all of the required manual parts off a sonata and onto a galant why would the gears be in a different arrangement? virtually nothing changes it shifts and drives like a convectional standard. I made this thread cause i actually installed it any other threads might throw you off.

[M-Rod]

The things I wonder about with using the Sonata transmission are the availability of poly motor mount inserts and a decent clutch. If somebody were to do this swap and later on decide to turbo their car, without access to those 2 items would be banging their head against a brick wall.

[Exhaust power]

Tiburon 2.7, the sonata 2.7 and G4JS share the same clutch as i see in my searches. So finding a good/strong clutch shouldnt be hard. The transmission mount is a great deal bigger then mitsu's but if needed im sure a urethane one could be custom @ low cost.
And for a lsd im sure a 3g one would work (dont have any hard facts but i read that info some where).

[M-Rod]

nice find on the clutch! I checked some things here at work and does in fact show that we sell the same clutch for the sonata 2.0 and the tiburon 2.7.

[Silvertune]

I highly doubt a Mitsubishi diff would fit in a Hyundai trans.

[Exhaust power]

nice find on the clutch! I checked some things here at work and does in fact show that we sell the same clutch for the sonata 2.0 and the tiburon 2.7.Yeah certain years the 2.4 and 2.7 engine share the same clutch for my na build i might run a stage one exedy which is good enough for my expected numbers.


I highly doubt a Mitsubishi diff would fit in a Hyundai trans.

Actually there the same transmission internally if memory serves correct ill have to triple check but ive done research but i never documented anything so i cant remember 100%

the 2.4L I4 and 2.7L V6 use the same tranny just different bellhousing, so use a LSD for the Tiburon 2.7.

[Exhaust power]

Thanks for the info! ill defiantly do more research to be 100%

[unclepaulie]

possibly wrong thread as this question is 6g7X related;


would any of the hyundai v6 gearboxes bolt upto a 6g7x?? say the manua box from a tiburon 2.7L v6? it uses the delta v6, and from pictures it looks to share the same bell housing bolt pattern as a 6g7x

[deeznutz]

^^^pics of said bell housing?

[unclepaulie]

^^^pics of said bell housing?

similar, but might be slightly different cause the delta v6 is only 'derived' from the 6g7x. only reason i ask cause a magna/diamante gearbox wont fit the chassis im wanting to put a 6g75 into so im looking for a box with a smaller housing

[Exhaust power]

I all ways wondered the same thing.

[mysticj]

the delta v6 is somewhat closer to the 6A1x than the 6G7x

[unclepaulie]

What about the bellhousing? Cause delta v6 bellhousing is more akin to a 6g7X then a 6A1X

[Exhaust power]

A good way to find out is to get like the starter plates to match them.
