A guy over on honda-prelude.com (free site) is getting a group buy together for sleeves. They are LA sleeves. I never heard of them, but someone is using them and running like 16 psi and they are fine. The price is 100 plus shipping. Check out his thread http://forums.hpoa.org/index.php?act=ST&f=2&t=4364 If you're in the market for sleeves it's worth a look. Mike
OK correction he's runnin 18psi and no prob's. More than 25000 mi on them. They're at a cheap price, not a cheap prodoct. Ludeconduct/preludex2 is getting a pair if that makes you feel warm and fuzzy and makes you wanna but.
Yes you have to take the block out and apart. And then to a machine shop. It's not a do it yourself job. Don't let anyone tell you it is. The money you'd send on stock h22 pistons you could buy my forged JE pistons and total seal rings for about the same price! All I want is 335 shipped.
PS- Honda pistons for H22 & H23 would not work with iron or iron alloy sleeves. The stock sleeves are called FRM (Fiber Reinforced Metal) , if you want to use forged pistons (which the H22/23 are not), you have to put iron sleeves in your block. Also, H22 pistons are several millimeters taller than the H23 pistons, so I believe the H22 pistons in a H23 block/head would probably smash into the valves...
Pistons are generally cast (as in pouring molten metal into a cast) or forged (shaping a piece of metal to a certain spec). I believe the stock pistons are cast. Both types of pistons would be the same size (bore), but the forged pistons are stronger. The reason you have to resleave the block has to do with metallurgical properties. If you have a hard metal rubbing a soft metal, the soft metal will wear away and lead to problems....Correctr me if I'm wrong 19924ws....

Have you measured? I know if many people that run h22 pistons in an H23 block. Considering they are the EXACT SAME block, I don't get why they would be taller. Not to mention I ran forged H22a pistons with my H23 crank and rods...
It's not that block that is the issue, it's the head...The quench area in the H22 head is larger than the H23 therefore giving you more "room" for the taller H22 pistons. The H22 pistons can be used with the H23 crank and rods as long as you use the H22 head...I believe the H22 pistons are .010 taller from wristpin to the top edge than the H23 pistons, plus the H22 pistons are slightly domed.
I dont get it .. i thought re-sleeving the block was to make the cylinders stronger so they wouldn't warp .. like in the B21 engine, the fiber enforced metal in a lot of those engines in 90/91 i heard wore into an oval shape and burnt hella oil .. so people would re-sleeve the blocks with iron and use stock or better pistson and be all good. .. and depending on the pistson, add some.

Correct me if I'm wrong...
Dana-
I was just talking to sik96prelude on msn about this he said they are the same height to the piston edge...he can probably come on and confirm.
Anyways the quench area difference is 53.8cc vs 50.0cc it's not that big of a differnce. But yes I know people with H22 pistons on H23 rods/crank, gives them about 11:1 CR. So it clears.

B21 engines do not have fibre reinforced material. They are just regular iron sleeves.... only the Prelude VTEC, Acura NSX and now S2000 use the FRM technology.
So those engines can't run forged pistons without sleeveing.
It's just a crappy consequence of the FRM technology.
But yeah in general people have iron blocks and can run whatever pistons they want, sleeving just makes the the block tough as hell
The pistons are not taller they are the same, listen to what satan tells you, he isn't going to give bad info. i have already doubled checked because he asked me to so there is your answer, as far as cheap sleeves, those words shouldn't be put together, I don't care who bought them.

So you're saying the H22 pistons with H23 rods/crank with the H23 head have 11:1 CR? Just trying to clarify...

Oh give me a break, nobody is trying to tell anybody they are giving bad info. I was just participating in a discussion and relaying info given to me by a rep quoting JE's specs....
Where does the H22 get the higher compression if the pistons are the same height as the H23 pistons while having a larger combustion chamber? 53.8cc vs. 50.0cc may not be a big deal in some things but in piston to valve clearance and CR, it's a hell of a lot...
And I don't think the subject was meant as "cheap sleeves". More like sleeves for a good price. Maybe that's why it doesn't read "cheap sleeves"...
Yeah sleeves for a good price. Not let's all go out and but some sh!tty sleeves. That would be a really dumb post. Oh and 3cc's is a real big deal, that's like 3 sugar cubes in size. It's how you distribute it on the piston or in the chamber that counts. So if they fit for you....great.....I'll never try it.
