Hey guys! Yet another 4g64 swap in a Lancer. I know, I could have bought an Evo.
I'm going a different route and shes going to stay with me, probably for a long time.
I just wanted to introduce myself and the plans for the Lancer. I'm located in Twin Cities and have long term plans for the build.

Well getting to the car, shes a 02 Lancer OZ with 139XXX on the clock currently. With this thread, I'm hoping it would provide me with guidance on the build and hopefully others who plan to embark on this adventure.

Thanks goes out to rpmruffryders, DarkMitsu, and others who have paved the way for us usdm Lancers who were given the short stick with the 4g94.

Here she is how she sits atm.


Here's the new 4g64 that's gonna go in after I build up the bottom end.



I got the motor off of car-parts.com at a local junkyard. Picked up the new heart for 600 bucks from a 2003 Chrysler Sebring. I don't have much atm because I'm still researching a ton. RESEARCH RESEARCH RESEARCH! That's all I'm doing right now and I'm probably going to tear down the motor Sunday so I can send her out to MAP to get the block sanded, honed, decked, and hot bathed. This is going to be a slow process so it'll take me a while to get her done.

Plans for next month are going to be forged rods and pistons, most likely eagle rods and Wiseco pistons at a compression of 9:0:1 or 8:5:1. Since I'm most likely going to drop in the Kia/Hyundai head because of the bigger chamber 56cc compared to the Evos 49cc(?) I'm going to stick with the 9:0:1 pistons and get her tuned at MAP or DB Performance.

Cheers!

 

i cant wait to see this finished! hopefully i cant start mine soon, but first i need to new tires. good luck!

 

Hmm, good to see another lancer stepping out of the normal of just boosting. Good luck with the build! I'm sure a lot of us will be following. Are you keeping it NA?

 

Thanks! I'm gonna keep her NA for now until I price together a turbo. Doing the dohc swap with the Kia head because it's so much cheaper then buying a evo head depending on where you get it. But yes, plans are for a 600hp build if possible. It's going to be expensive but well worth the time and effort doing something out of the normal. I'm shooting for 300 before I need a new transmission and drive shaft.

 

Wait wut?! Dohc Kia head? How did all this go over my head? So your effectively looking at a 2.4 dohc mitsubishi engine?

I had been eying the 4g93E dohc head swap. Down the line... Sometime... To get all that it's about $1200 but a relatively simple swap. You're buying an engine and new head and the price may come out the same maybe less especially if you don't have to make or get new mounts. OK, now you really have my attention. I know you're still researching but do you have more direction? What did the 63 come out of? What about the head? What is that coming out of? I'm about to go back and reread the sticky and see if I can pick up more than info.

You might want to hit demon up. He's about to do the same swap himself. I don't know about the dohc part though. Think he's keeping it sohc.

Edit: ok I looked, yeah custom mount, new tranny housing, maybe new harness. Came out of a Galant or Eclipse. Yeah you two have a small journey ahead. Good luck again. If I'm doing anything it's going to be a 93e.

 

Yup, you can use the Hyundai/Kia head. The 3g eclipse guys have been doing this because it's a cheaper alternative to the Evo head. The Kia head isn't as strong internally as the evo head but everything is interchangeable between the two heads except for a few parts that need to be kept on. It's an Evo head on a Kia motor the G4JS out of the Sonata, Optima, and Sante Fe. Just make sure it's the g4js. They are dirt cheap to get and are easy to get.

The 4g64 is avaliable out of the 3g Eclipse, 7th Gen Galant(correct me if I'm wrong), the Dodge Stratus/Sebring 2000+. Mine as I said came out of a 2003 Sebring from the junk yard.

Here are some links that I've been scouring through for information.

Club 3g has a ton of information. Thank you eclipse guys.

Hope the links help

 

This is how far I got, tomorrow or when I have time, the crank comes out. Looks great. no scarring on the connecting Rod journals.

 

The G4JS is simply an upgrade/update version of the 4G64 DOHC found in the 94 Galant GS. The G4JS and Evo head is different in three areas: The G4JS valve springs are about the same as the DSM ones as far as shape and design goes, and can handle stock Evo cams and mild 272 cams like Crower. The combustion chamber on the G4JS is larger, 56cc versus 43cc on the Evo. The turbo oil feed need to be drill & tap on the G4JS.

 

Thanks, new information.

Still searching for the pistons. I know they have then for the 4g63 head but I don't know about the g4js because of the combustion size. I'm thinking they should work but have a lower Ratio because of the larger chamber. Gonna look around for the math formula's.

 

Alrighty! Finally took the motor apart. Here are the pics of the crank and the journals! They are still in great condition from eye inspection and I don't see any signs of scarring.



















Everything should be set! I just need to get the rods and pistons then measure the oil clearance and oil rings.

Great deal on a Evo 8 head I couldn't pass up so it should be here in roughly two weeks. I'll update when I get the head in.

 

THE HEAD HAS ARRIVED! Great deal, brought the head over to a friend to inspect and he said it looked like it was ported/polished. For sure, it came with BC valves, Springs, and Retainers. Didn't come with a set of caps so I got some for 20 bucks. Gotta take it to a reputable machine shop to hone/bore them in with the head.

 

More pics of the head. I know I'm missing a cam cap bolt. AMS sells them for cheap so I'll pick some up from them.

 

Sub'd. Loving what I've been reading thus far. Great job, and good luck!

 

this is good...are you adding oil squirters to the block? a lot of evo guys that do this swap don't bother but it might be worth looking into while the block is being built...good stuff, i wanted to do this with my 4G69 and an Evo 9 head, but it was cheaper just to build my own turbo kit and reflash the stock ECU...and i don't have a money tree in my check list

 

Lol the money tree is there just for kicks XD. I am thinking about adding oil squirters to the block but it's still up in the air. If I'm gonna do a lot of high rpm circuit type racing then yep! Don't want those pistons to melt on me. But if it's drag racing, nah.

My whole summers busy, and I've had to wait on some parts so it's gonna take me awhile. But the slower it takes, the more time I can put into the details of the motor. Since I'm up in Minnesota, Map and Fullblown's just around the corner. But for sure, everything's coming together slowly. College this fall so I'll try to sneak some money if I can . But I'm just saving up right now. Still trying to find a good job since all the ones I had were seasonal. (broke out of high school student) But, most of my money's going towards the build and phone bills to help my parents out.

Next on my list is a reputable machine shop that has excellent service line boring cylinder heads if anyone can help me out. Then I'm gonna give Chris at MAP a hollar about what to do. High revving 156mm 2.4l turbo or a 7.5k rpm 150mm torque monster.

I can't wait to finish but I gotta take it slow. Don't want to mess up.
