ka24de block sleeves! anyone know?!?

[tlsdrift]

I have been looking all night and i cant find any website that has ka sleeves. I checked the forums but i couldnt find any related topics. Ive found plenty of sr sleeve but no ka wtf....wtf.....

we don't need sleeves because we have a cast iron block. SR's and honda motors need to be resleeved because they are mere aluminum.

What the **** dude do you think your driving a ****in honda or something with a ****in aluminum block or something are you ****in retarted.

that aside you could've come across a little more civilized

mucho if you're doing a motor rebuild on your own i suggest you do a lot more reading. and talk to the guy at the machineshop a lot they will teach you a thing or two.

[Swedish Mike]

It´s common to use sleeves in race engines, easy to swap when damaged and possible to use better steel. Also possible to bulid thicker cylinder walls and go down in diameter.

Contact LA Sleeves if you NEED sleeves, they sell universal ones, just give them the size.

There's no reason to use sleeves in the KA. If Ivan @ AMS makes nearly 900bhp on a sleveless block, I'm sure we can do the 300-400whp we're after just fine.

Yah true hehe, if you wish I could attempt one mroe time oh and don't worry I am a very friendly guy . So elt me say this. Don't Use sleeves .

True. But you never know the power goals, maybe 1500hp?

Given the context of the initial post, I highly doubt it's that high.

Haha, me too.

Sleeves will never be available for the KA because it is a closed deck design. The motor does not use sleeves at all.

It doesnt have anything to do with necessity, or power goals, or anything that. The design is simply different so that sleeves are not used. There is nowhere to put them.

Thought I'd clear that up.

Also S13FX, chill out. Jeez.

Oh take it easy guys I love everybody here hehe, that was more of a freakin joke then anything and I did appoligize hehe. IM SOWWY tlsdrift I hope you can find it in your heart to forgive me

Ok, listen...

I know what a closed deck is and I also know plenty of people using sleves in engines like that.Cast iron is the cheapest quality you can find and the really nasty engines blow holes in cast cylinder walls, often thin an inch down the cylinder for cooling.

You mean standing, open sleeves like Honda but there´s sleeves for closed deck engines as well. Often 2-3 mm thin walls and you can get them nicasil or teflon coated.

^^^ That is absolutely correct. V8 guys use them sometimes.

Thanks!

I saw the difference on Volvo four banger a couple of years ago, they couldn´t pass 1000 bhp, always blew the cylinder walls.They shaved off 1 mm and used 1 mm sleeves, still the same bore but took them up to 1250 hp and maxed out the turbo.

You´ll always make the cylinders stronger with sleeves, even thin ones.

We are talking hardcore engines here but just to make the discussion interesting!

[TrunkMonkey]

off the top of my head, sleeves are usually used for to reasons...

1. to strengthen/repair weak blocks (usually aluminum, thin walled, or open deck)

2. to increase ring sealing and reduce friction (serious race applications).

there's really no need to sleeve a KA block.

Almost the GAYEST thread ever...nuff said about that.

I know you're a Noob, the best way to find answers is to read a tad first, so you don't come off looking really ignorant.

That said, welcome to one the coolest forums on Nico. We have agreat comunity here where I like to keep things as easy going as possible. We screw around a bit here and there, but nothing should be taken seriously.

Try reading the FAQ in my Signature, it has tons of great info to get you started on the road to boost.

Best of luck and happy boosting!!!

The KA uses a sand cast block. As a result, wall thickness variance from block to block is relatively large. This is not an issue for it's itended applications or even some fairly high boost. But sleeving with stronger materials than the block can help increase strength to reduce failure and even perhaps increase power slightly if there is flexing occuring in a thinner part of the wall. Flexing can cause some of the combustion enegry to exit the chamber like blow-by gasses. It may also cause irregular wear on the piston rings and wall. Another things this can help with is if you are trying to maximize the bore. Stronger sleeves can allow one to run thinner walls, thereby allowing a larger bore.

Having said that, I don't know the availability of sleeves for a KA. Perhaps a good shop can fabricate or modify a set for another motor to to work on a KA.

Thanks, finally one with some knowledge!

You can find sleeves at LA Sleeves, they sell universal ones. Just tell them the size you want.I´ve sleeved a few engines, feel free to ask if someone are building a big hp monster.

I agree that most people will do just fine without it but you can never say "KA are bullit proof", there is no bullit proof engine and some day you´ll reach the limit.

Another good thing to know is that the wall thickness you see on the deck surface is not the important one.They always cast a bigger surface around the cylinder top to help the gasket seal. The wall are thinner down the cylinder and often around 3-5 mm.

I think you'll find that there are plenty of people on this board with both knowledge as well as experience. You should watch what you say, less you piss one of them off.

Perhaps I should rephrase. Sleeving a KA is a freaking stupid idea. Saying that it CAN be done and that it SHOULD be done are two very different things. The KA is not only closed deck, but has a fairly tight tolerance between cyls. Subtract from that whatever overbore is done for the necessary forged pistons, and you have a virtually unsleevable block unless you feel like sacrificing displacement.

I'm not impressed by the fact that some people have done this to other motors in the past under different circumstances for different setups. The fact of the matter is for this car, for this motor, for this turbo setup: the idea is not appropriate.

[WDRacing]

I agree totally, the KA is an anchor waiting to happen...sleeving a KA is retarded at best. The process alone is more expensive then buying any of the RB series. Lets not dwell on the minutia here, any motor can be sleeved, thats not the point. The point is...don't bother.

Calm down, I don´t want to make people angry...

The only thing I´m saying is this:

You can never tell people it´s not needed when you don´t know the blocks limit or weak point.Flexing cylinder walls can give you many strange problems and you need to have an open mind to solve it.

I´m not begging you to use sleeves but it can be done and it will help the big hp engines.

[Mangudai]

What is it tat makes this open? Is it the gap between the o and the block?

[KATwo40]

^^^ Yes.

[PapaSmurf2k3]

What the **** dude do you think your driving a ****in honda or something with a ****in aluminum block or something are you ****in retarted.

I LOL'ed... then I kept reading and came across

and I LOL'ed again.merry christmas everyone
