- In this video, I'm covering the install of my junkyard Dual Cam head onto my Galant's 4g64.
Head can be found in
1999-2001 Hyundai Sonata
2001-2003 Sante Fe
2000-2003 Kia Optima
This isn't a full how to, it's more of a guide for anyone interested in doing this headswap on the 4g64 equipped 8g Galant or 3g Eclipse.
You must use Evo cam gears, 1 of which must be an adjustable cam gear.

Thanks for sharing this detailed look at the swap. I've been knocking around the idea of doing this to my 3G Eclipse for a while. I've read up on all the forums, but this was useful to see some of the process on video.
I’m glad I could help. The swap is pretty easy and pays in dividends when going turbo.
SAME
So much information on all your G4JS swap. Thanks for all of it! I’m going to do it on my outlander this summer, just sourced a head at the junk yard.
I’m doing the same exact swap dope video hella useful info thanks so much no one else has made a proper video for this yet
WOW! this is very helpful for me!! I'm building a 2001 mitsubishi eclipse with the 4G64 SOHC. Swapping cylinder heads to a DOHC is a very good idea!
Good job doing it yourself and saving some money.
Just a couple of tips though , The balance shaft belt should have been replaced seeing as you had the crank pulley off and you shouldn't use worm drive hose clamps on plastic radiator's they don't allow for expansion and can crack your hose connection point.
Awesome video thank you my father was a Mitsubishi mechanic. Just picked an EVO 8 up and an Outlander
You just saved me so much time just looking up little stuff
Glad I could help
Thank you for this I was trying to do all the research for this on my own and it was a pain and I didn’t know if it would even work
Excellent info! Thank you for the video!
Good project, that KIA head will fit to a 4g69 engine
block, since I heard that you can swap the head of the 4g63 on to a 4g69 engine
block, the 4g69 has more high-end torque.
after 2 years did you ever found out?
@@GamingWithRobert yes I’m pretty sure you can swap any head from the 4G6 series between each other
@@mikehawk1673 what are the benefits of this, i have a 3g eclipse with the same 4g64 in the video and i want to know what would be the pros and cons to doing something like this to it
@@goldkiller2593 you can rev it higher with the dohc, it flows better, more power
@mikehawk1673 thank you, but like what are the drawbacks like anything in terms of reliability or is it even better because your replacing? But how much power does it really add, like is it enough to make it worth it?
Now to build an all engine eagle summit to drive my kids around in.
I do that crank bolt trick too. It’s always a pain any other way.
This was my first time trying it, I was nervous but it worked like a charm.
I'm not sure what the benefit of this swap to a kia cylinder head aside from being dohc vs sohc, if this is being turbocharged then completely understand, but if N/a then wasn't aware of kia making some serious air flowing cylinder heads, I'm in to all types of engines personally I'm a Honda guy and very into N/a power, and guessing this head swap gives significant gains in hp, being displacement of bottom end delivers torque? Very interesting what kia is cylinder head from
Dohc head flows more then the Sohc so it makes more power. Both Na and turbo builds will benefit from a higher flowing head. Plus the Dohc has off the shelf cam options available
Podrías subir un vídeo donde muestres a detalle como poner el tiempo, porfavor??
Perfect man thank you
Great job bro
A great video. 👍🏽
Nice job,I got a question plz,am swapping my 4g69 block to 4g64 ,will there be anny issues with the crank sensor, I notice a little deffrents with the cps plate,, the 4g69 has alot of spikes will the 4g64 only carry 2 cuts.do you think it would work with the 4g69 computer
Can stock Galant ecu run the engine after the swap?
Who year head ? For 2.4 soch eclipse
Hey dude great video how much would u charge me to swap my spyder gs like that 1998
I know this can be done on the 3g eclipse but can it be done on the 2g eclipse ? I'd assume the the 4g64 block is the same but I'm still learning. Awesome video man
It’s a similar process, but the 2g 4g64 block is oriented 180 degress different . You’ll need a different year Kia head
I might have to do this swap on my AWD Outlander 2003
Go for it. Then add a turbo. It should make a fun car. Also google Evolander, it’s where guys have swapped the evo motor into the outlander.
Hey bro good stuff. Did you need to swap out the ECU for the camshaft position sensors or was there a way to solder it to the OEM wire harness?
Thanks bro
Phoebus Castle
The sohc head has a cam sensor as well. All you need to do extend the wires for the dohc
This swap can fit in a 2005 lancer 2.0? And what model.of kia head you got im from mexico and i want to make that swap nice info 👏
Engine g4js
Will a 3g eclipse tensioner work with that galant belt?
Yes
Thank you for this great video. I have a question how did you know which engine head suites your 4g64? I have a Galant with 4g63 SOHC and I want to find a cheaper DOHC engine head than the Evo and I am researching for that.
The cheaper head is a g4js Kia head made from 99-05
My 4G64 does have a DOHC Head
@@Dgeigerd almost all have a single cam head, the Galant vr4 had dohc or the 4g63 had dohc
@@austin-lr3dx there are 4g63 sohc in other regiins the galant in North America are different from the EU Middle East and Adia
@@Dgeigerd thats not the Galant the Galant in America is different from middle east and EU it has 4g63 sohc
I have seen ur video I have a 2000 eclipse gs striker motor built Manley rods weisico pistons 1400 hd oem crank polished rods are from the 2g eclipse they are 150mms if u need that info pistons 86.5 from Stm tuned for evo 8 new valves head redone and aem true time timing gears stock evo 8 cams evo 8 cam reluctur and 2.4 galant dohc belt from 90s galant I'm using Kia optima intake manifold with the out lander throttle body gt35r turbo that's my build info
Sounds like a good setup, I’ll be running something similar. Do you have videos?
I have multiple videos on my channel if u need parts or advice let me know
I talk directly with map before doing mods
did u check my channel
still trying to find a galant DOHC belt after all these years
Use the 94 Galant GS belt or the Evo 8-9 Belt
Great video man and how about the same kindof swap for my 1996galant what parts should i search for to do the same job u did with that car
You’ll need dsm 4g63 parts. Either the turbo or non turbo 4g head from the 1g or the turbo 2g. You’ll also need a freeze plug to block off a water port. Other than that it’s similar
Hey, I did this swap and am planning on putting in some Kelford 272 cams. What are my options for tuning this thing? Did you do the tuning yourself when you turbo'd it?
Ecu? Did you use stock galant? And what parts did you changes from stock engine?
@@Badb816 Got a stock 3g eclipse ecu. new pistons and rods. Top end is identical to the vid except for the 272 cams
@@Booleany can't use galant stock ecu?
Bro. I’ve been looking for weeks now and I can’t seem to find a direct answer. What intake manifold will work on the sohc? The 03 outlander or the evo 8? I just want a direct bolt on and the forums go back and fourth about it. I’ve been watching your channel and you seem like you would know! If so which is better for a na application I’m not looking for anything special I just know the stock one is garbage and one of the other two is a direct fit.
The outlander will fit. Evo only fits the dohc.
How did you rewire the throttle position sensor?
Nvm got it 😁
What fuel rail did you use?
I lost it when you called the thread locker bacon lol😆😆
I used an Evo 8 fuel rail. I was in the garage for so long I was getting hungry lol.
I'm curious. You used the stock galant timing belt?
I want to do this swap to my 03 outlander.
You have to use the 95 Galant GS belt or the Evo belt
@@RvaJay thanks man. Loving your build.
Can you show us ecu work please
Once I’m finished with it I’ll go over the steps. I haven’t had time recently.
Awesome job bud! Question, Why did you grind down the fuel rail seats if you used the evo fuel rail? Mine fit with out grinding? Also, what tb is that from?
Really? Did you use different bolts? I couldn’t seem to tighten it down until I ground down the intake.
The throttle body is from an outlander
Hey what model kia did you get the head off of? I'm about to do this to mine but idk what to get the head off of
Head can be found in
1999-2001 Hyundai Sonata
2001-2003 Sante Fe
2000-2003 Kia Optima
@@RvaJay Thank you man. You're videos have been helping out more then the forums. I just got this galant for free and the head trashed
I have a Mitsubishi colt pick up with 4g64 engine, now I want to swap it with Diesel engine, which engine will be better
“Better” is really personal opinion. However If you’re looking to do a turbocharged street build, then the 64 is better.
Do head mivec fits in that block?
The evo 9 and 4g69 mivec heads should bolt on.
Hey guys
I in the middle of putting on my DOHC head from a 2002 Santa Fe and I’m try to time it but no belt I get works because the cams don’t have the same teeth pattern as the crank
What do I do
Which belt are you trying to use? Do you have an adjustable cam gear?
No on ajustable cam gears because I don’t know what types to get and same with the belt because I got two different belts from trying the 1994 Mitsubishi Galant. one was not the right grove pattern and the other was way to short. Honestly I’ve done American v8s and v6s only and this is my fist Japanese engine and car so it got me depressed I can’t figure this stuff out.
Lmao but I’ll keep trying tell I get.
The adjustable cam gear is a must. You need at least one on the intake side to make up for the taller 4g64 block. Otherwise the belt won’t line up. The galant belt or the evo belt will work.
Okay thanks for the info
Question man, does it really matter what head gasket you use? Like stock 4g64 or evo 8?
Stock evo has a smaller bore, you would need an aftermarket gasket that matches your bore size.
@@RvaJaygalant gasket will fit? 4g63 galant
Have a question bro, whats a good intake manifold to replace the old cracked grandpa?
For the single cam? The Outlander manifold is a good choice. It's cast aluminum and shouldn't crack
Hi I'm just wondering what Kia did that come out of
Hi,
I listed the years and models in the video description. Thanks for watching!
Did you have any issues with clearance on the lower timing cover when going to dohc? Ive noticed that the belt rides against the cover on the right side on my setup.
I did some trimming to get it to fit. It still isn’t perfect but it fits pretty good.
Cool video! Did you end up using stock Internals?
Yeah, I kept the stock internals. The plan is to build the bottom end after I’ve gone turbo and awd.
@@RvaJay thanks, I meant head internals. Did you use Evo 8? Or stock G4JS stuff?
What cams did you use? Are you using the stock Hyundai cams?
I used the stock evo 8 cams
More fusion videos please
Plz respond when you have time Will the 4g63 headers or front exhaust system fit on the 2.4L spyder ? Since nobody makes em no more
Which 4g63?
The headers will bolt up because the 64/63 heads have the same bolt pattern. They may not line up with the rest of the exhaust though
RvaJay aww man yea I believ my front headers are starting to to leak
RvaJay the 2.0 2G gst/gsx headers is what I was thinking it would it be best to just swap the head to 4g63 and keep the 2.4 block from the 97 gs spyder??
How can I get in touch with you, I also want to do that swap for my lancer since it is the same engine
Ok so what I've read up on is that you can use evo 8 cams, but i was wondering if you could use the stock hyundai cams or is that out of the question?
You can use the hyundai cams, I think the older model cams are more aggressive and good for NA builds.
@@RvaJay ah ok, i also saw that the hyundai valve springs are weaker but if it worked out for you and I'm not planning on revving out
I used the evo 8 valve springs. They can be found for under $100 and are a lot stronger
To do the head swap you need to tunne the car ?
You don’t need to tune the car, but it will help you get the most out of it.
What ecu do you recommend for now and when I put turbo
Evo 8 ecu is the best bang for your buck. The 01-05 manual Eclipse ecu is similar to the Evo’s but missing a few features. (Like boost by gear).
If I put the bigger thortel body without enlarging the multiple entrances, would it gain power? and which header do you recommend?
and thanks for your help
If the throttle body is too big your car will run worse without a tune but either way you won’t notice a big difference with just a throttle body.
Thats definitely locktite
Would this work on the 4g69? 04-06 Ralliart.
I think so, but I’m not 100% sure. I think it uses a different timing belt.
How did you do the cam sensor any modifications
I just used the stock evo stuff and extended the wires.
Could I do this to a 03 eclipse gs
Yes, it’d be the same process. Galants and eclipses are interchangeable provided the engines are the same
Would this set up work with 2g eclipse?
Depending on the engine, something similar could be done. But, this head won’t bolt directly to anything in a 2g
how much hp this give non turbo?
Not 100% sure but I’d guess 15-20hp
Hey bro you still got this galant?
Of course
@@RvaJay can you help me find a cheap place for good parts
I want to do something like that with my 95 Migthy Max.
I got a 92 and im trying to figure it out
I've got a 2003 Mitsubishi Lancer ES, would doing a trans swap on it be similar to the galant?
Im not familiar with lancers, but the process will be pretty much the same for any 4 cylinder.
@@RvaJay For 03 lancers they're v4 2.0L engines so they're basically just a little smaller. Ty man.
Hey man did you swap out the cam reluctor? I've been having issues with it
I’m running the evo reluctor. What problems are you having?
@@RvaJay I can't get my evo reluctor or bolt in. I think the Santa fe's might have a different cam
Did you get the evo bolt too?
The cams may be different though.
@@RvaJay Yeah I did
Did you compare the old bolt vs the new to see if there’s a difference.
Best bet is to get evo cams
Where can I find the valve gears?
eBay, Amazon and Facebook groups. Look for adjustable cam gears for the Evo
What's the benefit of going DOHC?
A slight bump in power because the head flows better. The benefits really come in when you go turbo.
@@RvaJay ok I hear ya I plan on going turbo on my 3g eclipse eventually. I'm in the middle of a RA turbo set up wit my 08 base Lancer.
Can this be done to a 4g69 ?
Yes
@@RvaJay is it the same process or any changes need to be made?
It’s pretty much the same. I believe you can’t use the evo/ galant timing belt
@@RvaJay thanks for the info
Pretty informational. question , what intake manifold are you using and TB? Also will the stock ECU run the dual overhead setup.
Evo or Kia/ Hyundai intake will fit the dohc head. I’m running a s90 evo throttle body currently. Yes stock ecu can handle
What head gasket did you use?
I used a Felpro mls gasket for the Hyundai.
What about 4g63 sohc in 8g galant? Is this headswap possible for sohc 4g63 engine in galant 8g too? Please reply me. Intake manifold from where?
The headswap for any 4g motor is basically the same. If you're using the Evo or Hyundai head, you'd need either of those manifolds
@@RvaJay i have got a outlander manifold my friend
@@RvaJay will hyundai cam angle sensor works with galabt ecu?
@@Badb816 you'll need the evo unit
