Hi, I came across on my travels, someone who was willing to sell me a aluminum 4g63 block with only 30,000 miles on it. Kind of weird, I have never seen anything like it. Light as a feather to. Whats the history with this?
 
I personally have never seen a aluminum block. The block itself looked alot like a head more then anything.

I guess cast Iron it is, but t was really light like hardcore.
 
hey man don't get down , look at it like this you have two options you can A buy the block and if it turns out to be legit you give every doubter the one finger salute. Or you can B purchase the block and if turns out to be a cast iron block, well you've got a donor block when your ready to build a beast. But either way man i think you win so do what you like but before you pass on the deal take some GOOD pics and post here so we can be sure that it is what it is man. pero tu ya sabes quen es mas puto=)


TU!!!!LOL
 
well im obviously not going to buy it if it isn't a 1.5. that's assuming the other 2 guys in front of me don't buy it. but someone on here was saying that there is a aluminum 1.5 Mitsubishi motor. well if its the one im in the middle of rebuilding at the moment i would love to have it!
 
That's Cast Iron.

But, Let's pretending that is Aluminum.

It still not a 4G643 Block.

Here are the Pics, Compare both of them, and you tell me if it is a 4G63 Block.

that block looks like its for a 2g 7 bolt... that block is supposley a 6 bolt, apprently its a custom made engine... cause the holds for the trans look like they would line up.
 
There are 4g63 blocks out there that have been aftermarket made - however do you have any idea what those would run you? The ones that have been made were made for people with bottomless pockets for evo's.
There is no factory aluminum 4g63 block, end of story.

Idt anybody knows what it is.

People say Its Cast Iron
People say It's Aluminum or could be.

People say its not a 4g63, then why does it say 4g63???

Its very light.

SoOoOo, I guess until I get some high def pics up, discussion should be closed for a while.

One thing I did not post up. I have a picture of the OIL PUMP SIDE, it looks identical to a 4g63, so that engine has to be in fact a block for a 4g63, it does not have liners, so I really don't understand why it would be aluminum but hey, who knows.
 
Yea let me just reach my arm 20 miles away and do that.
But yeh alright will do the magnet test.

The low miles make sense, but the lightweight doesn't.

Again I do not have this engine, it is 20 miles away from me locked up in a garage.
 
I just deleted 76 posts that were either thread bumping or off topic, if theres a 77th this thread is going in the Trash. Keep it ON TOPIC or it gets closed.

:dsm:
Might as well go for it.

This thread should be over and done already.

It is a 100% for sure thing, NO DSM had an aluminum 4g63 block, because there has never been one, not in an Evo either. As stated the closest you can get for a factory aluminum 4g63 block is the new evo one - however it is not a 4g63. The only ones are any aftermarket ones.
 
To keep it fair to the OP, and to keep other threads from appearing about this topic, I'm going to leave it open until its resolved. That is of course assuming the thread stays on topic with the OP.

Even if the oil pump bolts up, how does that prove it's a 4g63?
The one side looks nothing like a 4g63, and from those pics it doesn't look aluminum either.
Bring with a magnet, and an old head gasket to match up. And get some decent pics so we can actually see what it looks like.
 
That Block Is just Sand Blasted cast iron. Lock this thread up! and OP just give it up, The block is cast iron for sure and its just a early 6 bolt block.
 
How is it, that you guys know its cast iron from them pics? I mean seriously.
Because it isn't sleeved. All aluminum blocks are sleeved.


Terrible pics, BTW. Are those camera pics of the screen of your phone? Couldn't you transfer them to your PC and then upload them here to preserve a shred of quality?
 
Listen I know it's not sleeved, I mentioned I thought that was weird to.
What you guys need to understand is, that this block, literally weighs almost nothing,
thats the whole point of this. Even if it is cast iron this block is way to light to be cast iron. I mean I bet I could pick it up with just the grasp of one hand. No way you could do that with a regular 6 or 7 bolt they are close to 80-100 pounds bare.

I know what a fresh cooked and blasted block looks like, this block had a similar color but still different.

I wish the owner was on tuners...

But it has to be aftermarket for sure, not a REAL mitsubishi engine, I just think it's weird it is Stamped 4g63 and has numbers.

Again if it is cast iron, its the lightest cast iron 4g63 I have ever picked up.

prove it
 
What you think I'm typing on here for fun...

I was thinking, of doing the magnet test, bringing a scale to weigh it.
 
It's not aftermarket. It's OE to something. And so far, there's more proof to it being cast iron than aluminum.

How much is the guy asking for it anyway?

That's a good start.
