4G64 head possibilities

[manorchurch]

What, if any, 16-valve head will fit the 2.4L (1995) block (without having to cut into the firewall or reposition mounts)?

Yes, I mean fit -- like I carry the head into the garage and the old head unbolts, levitates, lands on shelf, while 16V head floats over, mounts all gaskets, and settles into place. My job: check the torque on the ARP set.

This is where I've been getting alot of 4g info. The site is pretty much for RWD 4g's so they'll tell you what will work on a 64 but I have yet to verify it but I'm curious about the starion 4g intake and head since the car is already RWD and that site mentions a hybrid 4g64 block with 4g63 head so there's some hope.

[manorchurch]

Yes, I've seen the material on projectzerog. Use of the 4g63 DOHC head requires cutting into the firewall to allow room for (if I recall correctly) piping to the water-jacket at the rear of the head. Or, you can cut, weld, and move the mounts forward to gain clearance, and use electric thermal fans instead of belt-driven (which is a good idea anyway, but that's neither here nor there).

Now, I'm not necessarily adverse to cutting out the firewall, but it lacks elegance. Anyway, there's a local guy who trying to sell his 1995 Mighty Max -- at a wildly optimistic price -- so I'm debating whether it's worth it to reset my plans to the 2.4L FI, and move away from carbs forever.

I have an Eagle Summit wagon, which is a 5-passenger variation on the Mitsubishi Expo. Love that car -- it's almost as good as a pickup. The engine is the 1.8L (1834cc) MPI SOHC 16V, and those extra 8 valves make a world of difference, fer shur. The DOHC version has 20 additional HP, putting it right where I want a pickup engine to be, pre-mods.

Trouble is, it's transverse-mount, FWD only, but Wikipedia says Mitsubishi sold that engine in an Outlander-like vehicle in the Asian market, called an L200?? Not sure about that, which would presumably be RWD.

So, maybe there's a DOHC head that fits the 4G64 and doesn't have firewall problems? Shucks, I'm willing to bet that the little 1.8L could do the job in a turboed variation. Hell, it gets 34 mpg around town, and the only time I need a turbo is when I'm pissed off.

Just wondering. Thanks for your input.

[recian]

But my point was the starion. Its a rwd car that came with a 4g63 so i assume its routed around the firewall.

[recian]

Its also a usdm car. Ive seen one in the junkyard that was a turbo. At the time i wasnt into mitsus so i dont recall if it was 2.0 or 2.6

[manorchurch]

Or the original mount design for the Starion cleared the firewall. Still won't go on the pickup mounts without cutting.

[manorchurch]

What's going on here? People were GIVING away Mitsubishis a couple years ago. That local guy with the Mighty Max sold it on the first call after the CraigsList ad posted. No questions asked -- or so he says.

Sheesh.

[manorchurch]

Hmm. From the picture, not so bad. I wonder if you could just beat it in a half-inch or so -- caaaaaarefully -- with a 2-pound hammer.

[manorchurch]

I'm sure that's it.

I was, like, in the mall last week. And this guy was talking up this chick about his Mighty Max project, and she litt-uh-ra-lee SCREAMED, "OMG, do you like, know Camoit, d00d?"

An eye-opener. Of course, she said "CUH-MOYT". Still, I was impressed.

Two weeks ago, while I was making plans to scuttle the entire collection and switch over to a Tacoma 2rz, this guy drives up my driveway, survives the dog attacks, walks up to the garage where I was fixing my cheapass Harbor Freight hoist, and says "Ya wanna sell that?" -- and points to the 88 Ram 50.

I said "No."

The solution to all my problems, right there. And I caved.

I'm sure that's it.

Cracking me up...

Sorry. Should be using the quote function for referencing.

Projectzerog has redone their stuff quite a bit. I looked it over this morning, learned a few things. One of my nephews has a couple totaled Eclipses, 90's era, in a shed on his backlot. Might be a head there that's interesting, although they got pretty rough treatment before giving up the ghost. It's amazing that kid can still walk.

[pennyman1]

to clear up some confusion in this thread, the starion/conquest(starquest) are all 2.6 astron motors. all 2.0 g63b, 4g63, and 4g64 are sirius motors and the parts are not interchangeable. any 16 valve head swap will require more than the head to make it run, including the computer, injectors, coil pack, and intake with throttle body, and a custom exhaust manifold. You will also need to change the fuel pump to match the needs of the new motor.

[recian]

Ah yeah the USDM only got the 2.6L

For the swap tho wouldnt you need to change the harness too? or just modify the existing harness. Info on that is limited and scattered and everyone does it different.

[pennyman1]

yes the harness would be needed to run the motor - it would need to be spliced into the existing truck harness.

[recian]

Are there any other possibilities for a head on the 4g64? Before I start looking for a stock head and cam

[DroppedMitsu]

Nope, only thing is 4g63 DOHC head but it doesn't just bolt on, lots more work needed.

So was this chick 3 foot tall,l no teeth and a flat head to set your beer on. If so she is the perfect woman.

She needs to have an ashtray in each hand to be a "perfect" woman. :-)

[sleeps]

I have never found this motor or head on a USDM mitsubishi, but its the perfect one for our trucks!

Can you add yours into the link section as well. Engine Parts: Engines and transmissions. (http://www.mightyram50.net/vbulletin/showthread.php/1581-Engines-and-transmissions)

We also have this place that sells the engine and trans as 1 unit. They have many of our engines in stock. There is a link in the link section. I have been there and it's a nice place. Lots of engines including diesels.

Beg to differ -- "perfect woman" has no FRONT teeth. Of course, I'm more "old-school", where the "perfect" woman is a deaf-and-dumb nymphomaniac who owns a liquor store.

I busted my tractor last week, jumping a stump and crushing the hydraulic filter, housing and all. Nothing to plow with, and on cue, it starts snowing.

You California guys don't know what real life is like.

I emailed them and said if they had one, at $495, I might buy it outright, sight unseen. However, if asking is $495, you gotta figure these have seen some hard use -- and it's kinda funky looking, like it comes out of a Mitsu box-truck before they went all diesel.

But, shucks, I can get a local reman for $1500, including the head. Local machine shop is a little hard-up for business -- doing my part for the local economy.

[sleeps]

The only thing i want from that would be the RWD mounted 4G64 16V SOHC head that would be perfect for bolting up the 4G63 Turbo manifolds and such.... Should also bolt up to our trannys and into our trucks just as the factory 4G64 motors do.

[recian]

Wouldnt that head bolt onto the stock 4g64 bottom end with no issues? I know that most lancers and galants come with that engine in the 2000s. That is just a RWD version of that engine without the spread port manifolds. And of corse some re-wiring for the newer sensors.

[recian]

So could the galant/lancer head be used with maybe the 2.6 exhaust manifold and modified intake manifold. I know the t-body comes out the back side of the motor so it'd have to be modified. But Both models came with different manifolds.

[Rahtid]

That engine was sold in the us in the montero sport for a couple of years, hard to find a 2.4 montero sport

[sleeps]

Thats what I originally thought but was never able to find out for sure, since this seems to be a pre OBDi or ii system, and the monetero sport's did not get them till 97 or 98, and rare at that. Ive tried to find one in a yard but never had any luck.

I also was thinking of fitting a galant or 3g eclipse 64 into the max if I ever was in that posistion to swap motors, but I sold mine before mine ever went bad. I love the 64 more than the 63 for a truck purpose. And to find something cheap, easy to find, and bolt on nearly all 63 parts was what I was after.

[recian]

The stroker 64 was made for the truck. It needs the longer stroke torque motor since its heavier than the car. However now that i think about it the eclipse 64 motor is backwards from the truck 64. That would put the truck exhaust on the driver side like every other mini truck. The jdm 64 u showed was on the passenger side. Now what about the newer mitsu black top dohc engine? Pretty much the only usdm engine they still make. I wonder if it would be possible since it has a lower profile intake and exhaust on the opposite side.

[Rahtid]

You can try the head from a 91- 96 galant,expo,eclipse spyder 2.4 97-99, colt vista, they flipped the motor in 97-98 on the galant

[pennyman1]

The difference has to do with the world motor starting in 97 - if you look at hyundais and kias, they are the same motors. Even the 4 cyls in chrysler cars till last year are the same world motor varient. That should open up some more possibilities.

[sleeps]

Ive looked into the expo's and older galants, harder to find, and the new ones seem to be cheaper in junk yards, but yes the intake and exhaust would be opposite sides. There were some hyundia's that had a 2.4 DOHC mitsu motor in the mid 90's. If you can find one of those... mint!

[recian]

I can find early 90s galants all day. Im sure any hyundai pre 2000 is in the junkyard. Thats where it belongs anyway. Finding them shouldnt be hard but the swapped sides is my curiosity. How youd make that work

[Rahtid]

If you can find the early 90's galant use that cylinder head,The flipped engines are easy to tell apart they have the engine mounted on the passenger side http://img11.imageshack.us/img11/9622/passengeri.jpg (http://imageshack.us/photo/my-images/11/passengeri.jpg/)
versus the drivers side http://img204.imageshack.us/img204/3752/driverside.jpg (http://imageshack.us/photo/my-images/204/driverside.jpg/)

[Rahtid]

here is a better example drivers sidehttp://img442.imageshack.us/img442/2057/driverside1.jpg (http://imageshack.us/photo/my-images/442/driverside1.jpg/)
passenger side http://img441.imageshack.us/img441/556/passengerside1.jpg (http://imageshack.us/photo/my-images/441/passengerside1.jpg/)

[recian]

If i was to yank that driver side head what else would be needed? The intake would need mods and the injectors im sure would be different.

[sleeps]

You need to find one with a coil style ignition, not a dist that sticking out the end, it wont fit!

[recian]

i noticed that lol but that narrows it down alot since the coil type was used when they changed the 4g64 from driver to passenger side mount. Maybe you can take the cam angle sensor and coils from the later style head and put em on the DIST style head?

[sleeps]

From what I have heard, yes you can. You would need a differnt ECU controller to understnad the signal, I think. The topic was a complete ecu turbo swap and using the turboecu from a dsm you can change the signal from the dist. to a sensor style so the dsm ecu knows what to do.

[recian]

If thats the case it would be easier to just drop a built 318 into it with a 727 or torqueflite. Ive got a spare 5.7 hemi at the shop that needs a new piston, rod and pushrods. :p

Now thats going to get you where you want to go.

[recian]

Yeah I'm not sure yet what I'm going to do. I'm going to buy another truck before I commit to it but The hemi has 100 more HP but it takes different mounts, has a harder to find tranny and isnt as bulletproof as the 318 and the 318 parts are cheap even tho there's more parts to convert the hemi since ppl put it in muscle cars. Lots of pros and cons for each. The hemi in a MM hasnt been done. Maybe try to find an Arrow. Nobody ever mentions it on the site since the MM took it's place. I found one in the junkyard last weekend with a 2.6L auto

[pennyman1]

the 5.7 hemi should use a small block mopar tranny, although there are belhousings out there for t-5, tko, and t56 trannies if you want to spend the cash for them

[recian]

If thats the case ill pair it to a earlier model 727 and call it a day. The mm already has the shift mechanism and kickdown linkages set up. if you ran a carbed setup with a 750 then itll be even easier. Just have to put a regulator from the fuel pump. I know mopar makes a kit to convert the engine to carbed. Idk how they do ignition system
