4g63 head on g63 truck block?

[Dizplacement]

I've asked a question similar to this a while ago about the 4g64 wideblock with a 4g63 head and came up with the oil ports being different... I own a starion and bought a 3000gt MAS air sensor for it only to find out that its not going to work, the fuel system sucks. I'm done with the g54... so on that note...

I located a g63 rwd block at a pick-n-pull in a mightymax or d50 or something i can't remember. Will the 4g63 head go right on without modifications? Or is it the same situation as the 4g64 wideblock where the oil ports aren't going to match up, since the g63 is a sohc head?

I am interested to know this too!?!?!?!?!!

as my next project is going to be a mighty max or d50 with a 2.0! I am sick and tired of a 300+ hp fwd eating up tires. so I am going to build something fun..

the mighty max from what I have found weighed in something like 2100 lbs bone stock! that could be lightened sub 2000 easily and be RWD.

I have all the engine components to make it work I just need the truck, ECU, wire harness, tranny internals

No, it won't fit. The G63 and G54B are physically larger motors. The bore spacing is different. The cam drive is different. If this was possible in any way, the guys over at the quest/starion sites would have long ago done it. You can imagine their hunger for a DOHC head.

Sorry, not possible.

There is so much mis-information in this thread, it is hurting my head…

Dizplacement,

Not all RWD blocks are “wide”. As a matter of fact, the “wide” blocks only came with very rare automatic trannys. So you really have to look around to find them. ALL 5sp RWD blocks came with the same bell housing pattern as Turbo 4G63 so they will not help your cause (unless you are looking for a RWD tranny to fit a Turbo 4g63). But I am not even sure that “wide” block will bolt up to a Starion tranny. I have heard several people claiming this, but never someone who have done it.

To answer your original question, I do not believe that you will have any problems matching up a wide G63 block to a turbo head.

Myblack98gst,

A base model, RWD Mighty Max/D50 is around 2550-2600lbs, which is light, but not as light as you thought.

Morphius, no one was talking about G54B motors...

Yes. You are right. I've got G54B on the brain. Looking at a techincal manual, it would appear that the DOHC head will fit the G63 block.

I knew it was 2.0L but for some reason threw it in the same family as the G54....... oh well. My mistake. I retract my previous post.

that answers your question

 

[na90dsm]

it works but if its going into a starion you have to flip the turbo around 180 degrees, there are 2 coolant passages that have to be shut just like the reg 64 hybrid. the starion trans bolts right up and so does the mighty max trans.

there is a mighty max that had 4g64 wide block motor in it.

 

[GRNDSM]

>the starion trans bolts right up and so does the mighty max trans.

You see, it is statemets like this that make me suspect this idea... Mighty Max manual tranny has different bell housing from Starion tranny. So how could the same block bolt-up to both of them?

Have YOU actually done this, or you just heard that it "should" work?

[na90dsm]

i have the wide block 4g64 in my garage. came out of a manual mighty max but will bolt up to a starion trans. starion trans has a wode block type bell housing on it. im gonan snap a few pics of that backign plate from the 4g64 and the 4g63 side by side., the bells are bigger.

ill also see about getitn pics of the trans with that backing plate on it.

 

[na90dsm]

63 plate on top of the 64 plate. obvious size difference.

this is the 2 side by side. same at the block just different out towards the trans

OK, this is beginning to make sense, it looks like the 4G64 (2.4L) motor which replaced G63 (2.0L motor) in early 90s, was "wide". But the older G63 motors were "narrow", unless you got an automatic. This is pretty confusing .

I would still be very intersted in seeing your "wide" block plate up against the Starion tranny.

[na90dsm]

yea im gonan get pics of that if i can. i need to get the trans and size it all up and make 100% sure they line up. i read in a bnch of places they do and they share the same bell housing size. but i have to see it to beleive it.

ill see if i can get em asap

I have a RWD 2.0 turbo motor (from a 90 GST) with a 87-89 D50 narrow MT... been done lots and its great. Havent broke it yet.

I am doing a 2.4L wideblock this winter. My 2.4 will be from a 6/88-6/92 truck as I believe this is a 1G design (so I can use 1G rods and timing components).

The 2.4 wideblocks come in 2 varieties... 1G and 2G. There is evidence of this when you look at flywheel (6/7) bolt configurations as well as wrist pin sizes (21/22mm). I'm pretty sure the Spyders are 2G designs and the early truck 2.4s and Hyundai G4CS are both 1G designs.

Remember.. I'm a Starion guy not a DSM guy so alot of the details of the 4G6x family get lost sometimes for me. I get alot of my info from: http://www.bestrebuiltengines.com/MITSUBISHI4.htm I would assume the castings are different enough that it would not work to use 1G timing components on a 2G block and vice versa. Also, oil pumps, BSs, etc. Can someone clarify and point out the differences?

If what I've seen in manuals is correct this means there are different timing belt configurations. So I'm wondering if the timing belt from the 94 DOHC 2.4 Galant (6 or 7 bolt?) will still work on either a 1G design or 2G 2.4 blocks.

Also... is there any info on piston CR for the 2.4 and 2.0 truck motors? I'm wondering if I can get by with the stock compression on the truck... and I'm curious if the valves will interfere with the higher compression pistons (SOHC vs DOHC).

Oh yes... this isnt wideblock specific... but what is the redline for a 2.4.. and what can it be? (example: 7500 on stock DSM ---> 8000 possible ----> 9000 racebuilt)

 

[na90dsm]

the 1g wide block form the mighty max is the same setup as a 4g63 but the deck hieght is taller. the water pump, front case and a bunch of stuff froma 4g63 bolts right up. you have to use the pistons made for the 4g64 but the timign stuff is from a 4g63.

i havent gotten the trans yet and prolly wont till the car gets built so im lookin for info on the starion auto trans pattern to compare it with the wide block bolt pattern


whats the cast code for the starion auto trans. thanx

Is this from first hand experience or from online sources?

 

[na90dsm]

first hand experience. i have a water pump from my 1g n/t that has same bolt pattern as the 4g64 water pump and lines up perfect. the frotn case is the same as well as the oil filter housing.

 

[poorboyj]

I second that. Those pic's I posted above are of my incomplete truck project. I used the stock 1990 Mighty Max 2.4L 6-bolt block and a 4G63 head. I had to use the ~1994 Galant 2.4L DOHC timing belt and head gasket, along with the DSM timing gears, front case, and alternator. Hopfully I will get motivated soon to get this thing done and write a little FAQ or something.

http://www.cardomain.com/memberpage/321988. Been thru all that with the 4G63, Now i have a 4G64 that i am building a short for this. The pic's on this site are fairly old and will be up dated shortly, there is no picture of my FMIC had trouble with the site but they were suppose to fix that.
The starion turbo trans is what i have in a modified gearbox case at the moment, but the original trans bolts straight on the 4G64(wide block).
You guys have it so easy with the LHD there is no steering box for you guys to try and get a decent exhaust passed.

Yea, and you don't have the brake mooster t modify to clear the intake manifold Anyways, do you have a picture of your water pipe off the car. The one between the head and the thrmostat housing?

Thanks,
Jay

Always cool to get info from down there... wonder if there are any differences in hardware, especially transmissions between the US and Australia. What's the deal with modifying a gearbox when the starion one bolts up? And have you looked into Pajero internals. I know there was a starion tranny with Pajero straight cut gears in it floating around down there.

And if you dont like the RHD stuff.. why not put an Evo4+ motor in it?

 

[blue1]

I have been chasing for an Evo 4+ head every where no luck down under!. The starion box is wide mount in australia there is a narrow housing 5 speed in a smaller car (sigma 2ltr) but when you see the size of the gears in them they would melt at 10psi. so i just got a 4 speed box out of a 2ltr commecial van line bored the layshaft bearings to 50 mm to suit the turbo starion set up,machined out the inner case by 2.5 mm to accept the bigger gears, had some weld built up around the starter bolts and reposition them. The 4G63 flywheel is smaller than anything we have over here that is six bolt! if i blow this box its a lot of work so the 4G64 hybrid is a better option then gearboxes are no problem! And dont forget to machine the flywheel to put a spigot bearing in!! Pajero X starion box have never heard of but will ask around.

 

[Majite]

For Those That Want To Know. The Early Mighty Max 5 Speed Tranny Will Bolt Right Up To The 4g63 Block. (if It Has A 110mm Measurement Between The Top Mount Holes On The Block. I Am Building A Turbo Charged Mighty Max As We Speek And Already Have Motor And Tranny Bolted Together. Waiting On Intake And Turbo Now. Will Post Picks When I Am Done. (this Is Darkwolf Not Majite)

there is a mighty max that had 4g64 wide block motor in it.

Which two coolent passages's are these?

 

[tumuchNOS]

I have a 77 colt with a 4g63 RWD set up. A mitsu 2.0 is a mitsu 2.0 as far as the block is concerned. All of the 2.0 blocks have side motor mount bolt holes, and the turbo motor will bolt up to a mighty max, D50 2.0 trans (at least all of the ones I have tried). Just use the mighty max 6 bolt (if you have a six bolt motor) flywheel and clutch. You will have to pull out/grind off the locating pin on the back of the crankshaft. The hard part is when you start making any power with slicks and the clutch that center force makes for the mighty max stops holding. I got into the 11 s' at 4500 ft elevation before it started to slip going from 3rd to fourth with a stock 14b on a stock motor. I havent spit a tranny yet (it pulled the left front tire I am told), but I work at junk yard so that wont be a real big issue. I am currently sending my 3 rd ACT clutch back. Next I will try a non-turbo 1G cover (pressure plate) with 23 spline by 1" clutch disc. If you all are interested I will post my results with that combination. BTW, the car gets like 35+ MPG and I built it for less than 3,000 dollars.

Oh and I cool through the front of the motor (timing belt side) and use a mighty max 2.0 water pump with some slight modifications. I made a block off plate for the thermo housing hole on the head and tapped it for the temp sensors. It took quite a while to find a pulley combo that would not spit belts, but there is a certain 1.5 mitsu motor that has the magic spacing to compensate for the additional impeller shaft length. I am currently trying to come up with an inline thermo housing so I can build some temp, its pretty cold here.

Hope this helps.
