Someone needs to make a spread sheet that lays all of this out, I would do it, but I am not experienced enough to get everything right. Having a link to a spreadsheet with all of the different motor layouts, what block, what pistons, what head, timing equipment, pistons, compression ratio, displacement, etc... I think trying to explain all of this in a thread is insane (no offense to the starter or those who have been helpful). A chart containing all of this TRUE information, created by people who know their stuff, is something everyone can benefit from.

Also, is there anywhere where you can get ahold of these motors near new...like 30-50k on them? I guess I have a feeling that if I am able to find a G4CS at a junkyard, that it will have a fairly worn motor. I was just curiouse if there is any kind of thing like what they do with the 1G 4g63's that ship over from ### w/ low miles on. Thanks in advance.

Ok...new approach. I am now looking for the 91 Galant 4G64 short block. I didnt realize until today that there was a 4G64 6 bolt application. So...the same question as above, but now im wondering if anyone knows where i can find a 4G64 block with relativly low mileage. Also...I see that SBR sells a lightened and balanced crank for the 4G64....would this be worth the extra money? Also do the lightened ones handle the stress as well as the OEM? Thank you

there were only 2 vehicles that had the 6 bolt 2.4, 85-87 galant and the 89-92 hyundai sonata. good luck finding one of the early galant motors. the g4cs from the hyundai are easily found for around $200 for the complete motor. hope that helped.

Didn't the g4cs come without a nitrided crank? I wonder how long it would last on high boost?

no, its coated for sure. my machinist was in awe of how good a shape my crank was in for over 100k miles when i took him my stuff. the g4cs DOES NOT have girdled main caps but the mains are physically beefier so thats a null point.

That is good, I was thinking about building one up for one of my cars, but I thoght that someone on th board said that the hyundai versions were not, so I lost some interest worrying about having crank troubles with it. I wonder if the 4g63 girdles would work on the 4gcs?

no reason to. youd have to spend the money to line hone the block and new mains and its a pain in the ass so your machinist will hate you.

yeah, and he'll piss on your block. i've got a g4cs block that i'd sell for the right price. it's been at the machine shop since the day after i got it. the machinist hates me because i'm asking him to do things he's never done before. pm me if seriously interested. don't bother low balling because i've all ready put a lot of time and money into this project, but i'll give it up for the right price. they are getting hard to find.

sorry for the dead thread revival bu i read the entire thread got some part numbers yadda yadda, however...there was a company selling fresh g4cs's on here (i got the last ) and he said something about using a 89-91 sonota water pump...now i know this falls under the "everything switches over" but i just want it to all be right the first time...another thing ...yes you use mitsu headgaskets.....but off of what year and what car? this also was not specifically debated thank you for your time

Question

There is a LOT of information in this thread. I have read pretty much every thread on this site as well as a few other sites about the G4CS build. I'll go point by point and someone who knows better than I can clarify if I got it wrong.

1. The G4CS is the same block as the 4G63, just 6mm taller. It is not uncommon for manufacturers to just share platforms. Mitsubishi has done this with Chrysler-Dodge-Eagle and Hyundai for years. If they are actually the same engine block, the castings would be the same, right? That would also explain why everything from the 6-bolt 4G63 transfers over.

2. The extra 6mm makes the deck height the same as the 4G64, so the 6-bolt 4G64 timing belt is needed. Here is where things get interesting. You could also use the DOHC 4G64 camshaft gears, or you can remark the (4G63?) gears, but someone in this thread mentions just using (4G63?) aftermarket, adjustable cam gears. I'm assuming that if you can remark the (again is this 4G63?) gears, then adjustables are a no brainer, as long as you can adjust them far enough.

3. The extra 6mm (in both directions) allows for the use of the 100mm stroke using the 2.4L crankshaft (100mm stroke) which can be found in either the G4CS, or the 6-bolt 4G64 found in the Galant. The best way to do this is order a factory fresh 6-bolt 4G64 crankshaft.

4. The only clearance issues I've seen brought to attention is the downpipe. Since the head sits 6mm higher, if your downpipe is too close to the oil pan (or is it oil filter) then you may have issues. What about the intake (turbo inlet) and turbo-to-intercooler pipe?

5. Oil squirters have been used, and have not been used. Use your descretion. I don't want to reopen this argument, although it has already been resolved.

6. Factory pistons from the 1G will yield a very high compression ratio. Use of aftermarket, super low compression pistons will correct that. If the block is the same, then couldn't you use any super low compression 4G63 pistons?

7. What is the rod ratio of the G4CS (basically what is the length of the 4G63 rod since they are the same and we know the stroke of the 4G63 and the 4G64/G4CS)?

Anyone have a good source for 6 bolt 4g64, g4cs cranks? And is it advisable to stay away from ground cranks because of the loss of surface harding (factory nitride coating)?

Can anyone clarify on the crank timing plate?

I'm going to buy a friends G4CS and wasn't clear on which timing plate to use? Or are they the same? It would suck to get my engine together only to foul the valves and everything else up on initial start-up. I think I read only ONE person said to use te G4CS crank timing plate, but I just want to verify with everyone else who has one running.

Thanks.

I used the crank timing plate from my 4G63 on my G4CS. It seemed to work fine.

I'm not real knowledgable on the G4CS but the 4g64 has a larger bore than the 4G63. Also the 100mm crank can be used in the 4g63 which makes the 2.3l stroker. So for the pistons you can not use the factory 1g pistons because they are the wrong bore.

Use everything off of a 4g63 except for the cam gears and timing belt. The stock SOHC pulleys, timing plate and all that will not work. I tried. The balance shaft crank gear has the wrong spacing on it and makes the timing belt ride out towards the edge of cam gears, I can't remember what was wrong with the crank timing belt gear, but I'm pretty sure it was wrong. The crank timing plate causes piston on valve contact.

Always turn the motor over by hand if you've been messing with the timing belt to make sure everything is right.

When you say 4g63 you mean a 6 bolt right? Will the mitsubishi balance shaft elimination kit for a 6 bolt 4g63 work on a 4gcs?

To the guys with 2.4's:

What are your track times? Any dyno results? Have you run into any problems? What clutch do you guys recommend to handle the extra torque?

Yes, the Mitsubishi parts for eliminating the balance shafts in a 6 bolt 4G63 will work in the G4CS. That is what I used. Whenever I said "4G63", I mean the 6 bolt turbocharged 4G63 engine, that came stock in my 91 Eagle Talon TSi.
