Titanium Sleeved Block still good?

[Rated-x]

Ok I know the 4g63 block dosen't need to be sleeved cause its solid but i just recently received a block that was due to some damage. now should i toss this one out or is it better then a factory non sleeved block

WTF are you talking about..titanium sleeves?

 

[14.5 drift]

I understand titanium is torsionally very strong but how would it hold up to the heat?

 

[NoMatchTsi]

As far as i understand Ti has a melting point that is 225 F higher than iron. The 4G63 bolt is iron. By adding the Ti sleeves you could run the block 225 F hotter than you could on a normal iron block

Iron Melting Point 2795.0 °F
Titanium Melting Point 3020.0 °F

Thats all i would guess. But i am no expert

goodness... what is going on

i hope you never build any motors with that logic

They make titanium sleeves for our engines?
Whats the melting point of carbon fiber?

Sleeving the 4G63 is just stupid... That is all... :thumbdown

Complete twaddle. Cylinder walls care much more about lubrication characteristics than they do about heat. Cast-iron rings running in titanium sleeves won't live long. I doubt seriously they'd ever seal.
How do you fantasize running coolant in that 225°F hotter block? Switching to liquid sodium, are we?

It's good that you're thinking. You just have to move your depth-of-field up a bit.

Of course, we were supposed to be running ceramic pistons, cylinders and turbines ten years ago, too.

And where the hell's my rocket belt?

. That guys up pretty high. I wonder if his rocket pack uses titanium sleeves with ceramic turbine blades.

so i guess i should just get rid of that block then i really wont know intill i take the head off

Speaking of that. My father is a mechanical engineer (go figure ) Anyhow, in the 70's he worked for Williams International in Walled lake, Michigan. Anyone remember the first rocket belt that was shown in one of the James Bond movies? That rocket belt was designed and built by Williams international. They have it in their showroom along with a jet powered lawn tractor and a jet powered snowmobile.

Here's a link to their site, but no pics of anything above I mentioned. http://www.williams-int.com/index.htm

since when do people sleeve dsm blocks?

Is it fun to talk something you don't know anything about?

Guys take it easy. "Solid" cast iron blocks are getting sleeved on a "daily basis". Sometime it is the only way to bring certain blocks "back to life". While most sleeves out there are cast iron some exotic materials are also being used most of them ceramic based even though the promised ceramics never delivered.

But back to the regular cast iron sleeves they are sometimes better than the stock castings and are checked for imperfections in ways that a block cannot be.

Bottom line a sleeved cast iron block is not necessarily a bad one if the sleeves were installed right and sometime it needs to be sleeved.

Very true, a lot of cast iron Honda blocks are sleeved, but for the cost, I wouldn't bother. One could easily find ANY DSM block a lot cheaper than it would cost to bore out the cylinders and the cost of the parts.

It CAN be done, but unless there is some crazy sentimental value in the block, why bother?

 

[14.5 drift]

Only because I havn't ever heard of a Honda iron block, mind telling me which ones your talking about?

 

[sonicnofadz]

I'm not too familar with Honda engines, but from what I have heard and seen from experience, most Honda engines are all aluminum. What Honda engines have a cast iron block?! Perhaps some of the older cars?

So I'm a knucklehead, I'm going by a friend's experience/knowledge of Honda's, which is apparently not so great, but he recently told me some of the REALLY older Honda's (late 70's) had cast iron blocks, but that wouldn't be an every day occasion, and pretty irrelevant.

so i guess i should just get rid of that block then i really wont know intill i take the head off

So then, what _are_ you talking about? Are you asking about using titanium to sleeve a block, or are you just getting a block that was damaged enough to require being sleeved?

If you do have a sleeved block, bets are that it has iron sleeves. But no, it's not usually done on a DSM. Blocks like Honda's that are wet-sleeves to start with are a completely different scheme than an iron block.

yes i already have a sleeved titanium block the motor has already been built and running theres just littile problems with the car i plan on taking the motor out and putting it in my awd i wanna know should i keep the block or toss it

this is what i know thats been done to the engine
-sleeved titanium block
-knife edge crank
-je pistions
-forged rods
-port and polished head

 

[slowAWDTSi]

I must ask where did you find this jewl of a titanium block? I must know
Its too late for me I just got my forged motor done but I have a few friends that have money

To answer your question, keep the block on hand you never know when it will come in handy. Usually a .020" over to .040" over bore will take care of any scratches and it can still be used with no real problems

rated x,
I noticed your join date of 05-02-2004. How long have you been modifying DSMs? Like other people have said there's no logical reason to sleeve our blocks. If over-boring it doesn't take care of the problems you usually find another block. When did you buy this engine? How much did it cost you? Where did you buy this block from? From what it sounds like someone has taken advantage of you. I've been there too when I was younger but I didn't buy a titanium sleeved block however.

 

[burldude]

You cannot run iron rings against titanium . I have worked with titanium making exotic parts and it gulls far to easy to use in cylinder walls . I just dont see this happening.

i paid nothing for the engine soon as i take the engine out of the car i will let you guys know something
