I have been seeing an increasing amount of posts pertaining to the possibilities of swapping the Mitsu 4g63 into various Hyundai cars. Let's clear up the confusion and lay out some falicies about the relationship between Hyundai and DSM.

First off the older Hyundais (1990-1995) were very loosely based off a Mitsu block design. After that year the only similarities between the two engines is the fact that they run off pump gas and have 4 pistons. Nothing more. Agreed, the engines <i>look</i> similar in shape, size and placement. The most notable difference is the fact that the engines cams are on opposite sides.

As for the Mitsu turbo manifold, it will not fit, at all, period. I had 2 of them from each the 1g and 2g Eclipse and they almost line up with the exauhst manifold gasket from the Tib/Elantra. Almost. It would take a miracle from Zeus himself to make it fit.

If you <i>really</i> want to make this swap happen get ready to take a second loan out for your car. It takes bucks. Since nothing matches as far as motor mounts, tranny mounts, axles, hubs, internediate shafts, ECU, wiring harnesses, shift linkages and a sleu of other things it would take a master fabricator/installer a solid month just to get things to a point to where the car is drivable.

Granted, the 4g63's tunability and bulletproof components are unsurpassed by few but the fact remains that this swap would be not only very difficult but could turn into a financial hardship.

My advice: If you have a Scoupe, Accent or older Elantra do a swap with the 2g Beta Tib/Elantra engine and tranny. Not sure how many of you follow the other boards (namely FXtreme) but there are engine internals available to make the Beta engine strong enough, with the proper tuning, to handle a good deal of boost and satisfy our ever growing need for more horsepower.

So please, I ask you kindly to keep the Mitsu vs. Hyundai comparos to a minimum. If you do decide to venture into the 4g63 swap please find a reputable shop that is familiar with BOTH Mitsu and Hyundai and I wish you luck.

Ok I'm sure you know alot more than I do about Hyundai's, but here is the thing...
Hyundai's 93 GL-S head fits on to a 1g dsm 2.0L turbo engine. Only difference in it is that the ports are smaller. The turbo manifold DOES bolt up. Trust me because I ran a Hyundai head on my 91 Talon for quite awhile due to jumping the timing on my own head. So basically what I'm saying is that even if the entire motor woln't drop in and mount up then I can still put a mitsu turbo on the bitch and raise the boost untill the block bursts. With or without help I'll put this elantra into the 12's. I've done it with a car that weighs 600lbs more I can do it with this elantra. I'm seen and heard of the 4g63 install into the elantra, so it has been done before. I'll be doing it without a shop doing the work for me. I've been working on 4g63's for years, but now that I have an elantra and actually care about making it fast I've been trying to find out more about them. Without any help so far. And I'll be taking pictures of the install and I WILL put up a site to show the step by step instructions on how to do it yourself. So others like me will have a reference to go on. No offense, but it will happen. Soon. Wish me luck...

Nusense, you're correct because you have an older Hyundai which used Mitsubishi motors.

Tom was tossing this out more of a general reference to everybody that believes the Beta 2.0L is the same as a 4G63.

my newly rebuilt 4g63 is almost ready to be droped into my 93 elantra... Just so everyone knows I plan on taking pictures of the entire swap including instructions on how I connected the ecu and all wiring harnesses. Here is a list of the parts I already have off my talon that will be going on the elantra: 4g63 block & head, 16g turbo, turbo housing exaust man and o2 housing ported, 2.5in innercooler piping with frontmount innercooler (griffin core with spearco tanks), 550cc injectors (RC), Apexi AFC, Extreme manual boost control, modified 1G blowoff valve, 2G intake neck, 2G intake and MAF sensor, foam filter (forget the brand), no emissions, no a/c, no power steering. I'm sure I'm forgetting alot but you get the idea. This is a mid 12 second setup in a talon (which weighs 600lbs more than the elantra) so lets see if I can get traction and put this car in the low 12's... <img src=icon_smile_cool.gif border=0 align=middle>

Someone must of forgot, the older gen sonatas have the 4g63 motor also, they stopped the mitsu motors in 96 which is when my 97 sonata was made. I have a 2.0 turbo 4g63 motor coming soon that pushes 220hp, without any of my other mods. I know my car is heavy but it will have some go when i am done with it. For all of you who want 4g63 motor, go for it, anything is possible, it can be done. There will be one in my sonata soon, and if i can do it then i am pretty damn sure you can. Hey, 4g63, it must be nice having a daily driven 14psi hyundai, i hope i can do the same soon.

Thanks, autobot, everyone is doing alright besides the fact that the car club from sav is racing and getting caught at hutchinsin island. I found a jdm 2.0 motor in import tuner i think, but it is $2000, but i will need another 2000 for the tranny swap, but it will all pay off when i get the finished product in march. i can't wait. Rich is saving up to to do what you said, the tib motor swap into his accent. So we will be set in just a few months. We will put some pics up when we finish the cars. Have you done any mods to your accent.

No not yet cause I have been trying to get things paid off and also moving into my new apartment<img src=icon_smile_sad.gif border=0 align=middle> But it looks like I will mak my Xmas bonus and if that is the case I will have enough money to do the swap and a few other goodies in January. The nice thing is that I live right across the street to the mall of America so I can walk to work when I am getting the work done<img src=icon_smile_big.gif border=0 align=middle>
