a possible project

rebuilding my old GS block. probably at the end of this year or the beginning of next year. I have to go pick it up and tear it down to see if the block is still useable as well as parts to sell such as the 60mm TB. I know a piston & valves are broken but I don't know if it affected the block or not. the cylinder head...I highly doubt it. so here is the possible upgrades I have in mind:

custom 87mm wiseco piston (10.4 to 10.8 CR)
a 4G67 cylinder head
either COMP or HKS cams
crower springs and retainers
stainless steel valves
balance craftshaft
B/S removal
Eagle rods
62mm throttle body
390cc injectors
coil on plug coils (MSD)
*knifeedge craftshaft
*jdm cyclone intake manifold
*rpw street header

(*debating)

any suggestions and comments are welcome

damn, got compression ratio? why so high?

lol, i know 10.8CR is a 'little' high but I'm really considering around 10.5 cr.

4g67 Head? Did your timing belt fail? Your pistons should be ok unless they cracked, which I doubt they did.

please educate me, 4g67 is a _____ .

Either he means this JDM, or a typo at worst.

I believe 4G67's were equipped in old school Mitsubishi Colt turbos. Basically it looks like a 4G63...but its 1.8L.

Nah the turbo Colt/Mirage motor is a 4g61t, at least the 89-91 turbo motor. Have no clue on the older older style mid-80s colts. I think the 4g67 came in some of the early to mid/late 90s Mirages.

[Edit]
Google tells me the 4g67 came in some 93-95 Elantras, the 6g Galant non-turbos(I think), and the Eterna(sp?). Not sure how big of a motor is but it looks to be DOHC

[Edit x2]
Ahhh I remember this motor. Its basically a 1.8L version of the 4g63(not the same turbo Colt 4g61t which is 1.6 or 1.8L). But I remember a lot of people getting scammed on ebay thinking it was a 4g63t. People would relabel the auctions and put the red JDM valve covers on them and sell them as 4g63t. I remember John got one a few years back. Not sure on the differences in the head vs a 4g63t head though.

Yup, you are right Seth...4G61 was in my head but wasn't sure :oops: I am sure the cylinder head is compatible with a 4g63t...the basic design is most likely the same.

Yes 92-95 Elantras and the I think the 4g67 I read about in the non turbo 6g was a swap. I stole my valve cover off a 4g67 Elantra:

yeha i sold the head off of it and the block has been sitting in the corner of my garage for 3 years now.

i think its time...

i'm going to toss it over a bridge tonight.
would make a nice breeding ground for the aquatic wildlife in my area.

i want pictures of the splash lol..

yes, the 4G67 and the 1G 4G63 heads are the same...except the combustion chamber is around 43cc for the 4G67 and the 4G63 is 47cc.

they are mostly find in the 93-95 Elantra GLS.

Before the 4g61 (the grandpa of the 4g63) there was the G32b Which was a Throttle body injected 1.6L turbo found in the '83-'88 Colt Turbo. It shared the same turbo as the VR4 3KGT I believe it was a TD04. I had one, it was a colossial turd.

im gonna go with a 4g63 head swap and redo my internals.

i'm currectly changing the cylinder so i'm going with the elantra one. planning to keep the GS exhaust cam but I don't know what intake cam should I use.

Look what the UPS man drop off to me Friday. Don't know how to post pics! :roll:

cool.
since you are going to have the machine shop mill that head flat, might as well have them install some new valveseals(or install them yourself)
most turbo heads have fried exhaust valve sealls after being abused for 80,000 miles and more.

you cna get a set of viton seals for around 20 bucks. i think seth actually has a complete set lying around, you might as him about them.

are you missing some valves?

lol EEEWWWWWw the guy before you ran bosch platinum plugs.
yuck




btw,
you are going to have to get yoru head drilled and tapped fo rthe 94 gs fixed cam position sensor. the pickup has to bolt to the head and the 1g head does not have the holes for the pickup to mount.

your other option
(probably the better especially if you are going all motor)
is to use the 1g cam angle sensor.
just like a distibutor this one can be clocked to adjust base ignition timing.
a big bonus for you, mr all motor.
i would still use the factory crank position sensor. its better to ahve an actual crank trigger signal than a simulated one.

Yes, four of them.

this cylinder head is unique: it's like the 1G just with a smaller combustion chamber. i just have to hard wire the 1G cas to the 2G plug and leave the yellow wire disconnected. i'm plan on using my GS exhaust cam and most keep the intake cam. i read somewhere that majority of 1G intake cams are about the same except for the m/t turbos.

i notice on my GS cams, both cams are stamped with the letter 'G' while on the hyundai one, the intake is stamp with a 'D' and the exhaust cam with a 'B'.

btw, i paid $130 shipped for this thing. there were others as low as $50!

why are the valves out?
were they bent?

if thats the case you'll need new guides cause they almost always crack when you bend a valve.

while we're on the topic, other than the cams, what valvetrain are you planning to run?
stock springs, guides, retainers, valves?
or are you bringing something big to the table?

cant wait to see the finished product man.

bent? they look if they were broke off. the head suppose to be off a 'good' motor but nevertheless, it's still needs to clean, pressure test, and have those guides and valves replace.

valvetrain just stock for now...i don't mind getting my hands on an intake cam from the JDM '89 Galant AMG. that cam have something like a 260 duration and 10mm lift. or probably the intake cam from the GVR4.

maybe a custom Coil-on-plug ignition with a MSD DIS-4, 390cc injectors, and probably chipped the stock ecu with either the rare-and-hard-to-get 4G63 AMG, 2G auto turbo, or custom fuel and timing maps.

bringing anything bigger to the table? well, not now...suppose to move to NC in the august, and my old block is in some junkyard right now. i was planning to sell the TB, IM, coilpack, and any other usable items to fund this project and as well prep the shortblock if it was repairable. i guess i'll use my refund check next year to purchase a GS shortblock.

what part of NC are you moving to?

just get a 2g eprom and run dsmlink. you'll be able to adjust fuel, have complete control over timing, and tune for knock. doesn't really get any better than that. don't forget launch control, adjstable rev limiters, hacked mas compenstation, adjustable deadtime and pulsewidth to make even massive injectors run like stock.
if you don't want to or can't shell out for that, don't waste your time looking for some overpriced fabled ecu... just get jeff olberhertzer to burn you a customized chip for your eprom. he's the owner of dsmchips.com. he burned my eprom, and i love it

i was thinking about the 2G eprom but for the bigger project i have plan for next year. the fabled ecu, the one from the rare jdm galant amg, is more for bragging rights. https://www.thegalantcenter.org/styl...ault/laugh.gif

btw, the 4G67 cam gears are like the one from the GS with the half tooth notch for aligning timing.

The car should be up and running within the next two to three weeks, and after some number play it would seem like the compression ratio is going to be around 10.6! But I won't know for sure until I get a compression test. See ya.

what pistons did u use? i want i high compresion ratio as well.. esp since im not going turbo..

just so you know, if you use a 1g ecu, yoru speedo won't work. i know this from experience, and so did Sabzi.

great to see yoru motor is almost there.

one more point to getting a 2g eprom, is that if you decided to run a cyclone manifold, you can have jeff. O. burn the chip so that it uses one of yoru solenoid drivers to properly operate the cyclone actuator, by using your existing wiring.
since the cyclone manifold blocks off the egr... you would use yoru egr solenoid to control the pressure going to the butterfly actuator on the manifold.
thats how mine is setup. opens the secondaries at 4100 rpms.

And with a 2g ECU, your tach will not work. Sabzi will tell you that as well lol.

Only way I could figure is the tach signal is different on a 2g ECU. Even with a tach adaptor I dont think its possible. Might be able to work with a 94 GS cluster. But I think I am just going to build a custom cluster with aftermarket gauges.

when you drive throough for the gap.... you can try my cluster.
maybe it will work for you.

i think the signals are inverted. between our ecu's.

my speedo is inverted, and your tach.

<div class='quotetop'>QUOTE(SuperGALANT)</div><div class='quotemain'>what pistons did u use? Â*i want i high compresion ratio as well.. esp since im not going turbo..</div>

the stock GS pistons. it's the cylinder head, it is 4cc smaller than the 2G head. I was expecting an increase of .4CR instead of .6CR.

So with the 1G ecu, my speedo won't work and with the 2G my tach won't work! Weird!

Well, it look like I have to wait another two to three weeks for the GS to be finish. Apparently, my mechanic was in the hospital for awhile. So until then, continue the distributor/dohc searching
