I'm not too familiar to prelude family motors. This friend I know is in process of turbocharging his 2.3L nonvtec motor. His motor is eating oil badly like one quart a week. I recommended him build his internal but looks like if the rings are bad and cylinders are warped or deformed he need to sleeve it. I'm pretty sure his motor is a close deck so what sleeve you guys recommend?
Second senerio:
His oil eating has nothing to do with the sleeves but he is changing to JE pistons anyways, I have heard someone told me that prelude motor will need resleeve regardless if adding aftermarket pistons even it's stock bore size, so is this true?
Could he just hone the cylinders instead?
Help the man out, kinda lost.

 

There was a big interesting thread about this about a month ago. From what I understand you can't use forged pistons with the prelude fiber reinforced sleeves. So you will need to get the block resleeved.

Golden Eagle does the best sleeving work right now for Honda's. http://www.goldeneaglemfg.com

They're excellent, and I wish I got my block sleeved by them. After that, getting a Darton sleeve kit would be acceptable, but I'm not sure if they have a kit for the H23a. Actually I doubt the kit would be different than the H22a kit since the bore is identical.

doesn't JE recommend you Hone your cylinder when installing their pistons? and wont Honing the pistons "eat" through the FRM?

can anyone confirm this?

EDIT: and I think if you're running high boost 12-15+++ PSI you'll have to re-sleeve it anyways. even If you think about it, if you upgraded your pistons and rods it'll only be a matter of time until your cylinders crack due to high cylinder pressure.

I believe the Honda manual has specs for honing the cylinder walls. You have to use a micrometer to measure the specs, I'm sure, but I believe you can hone the walls if you use Honda Pistons. I went with JE pistons and Eagle sleeves. I am very happy with both, but Damn, it cost some green.

 

The factory manual also says overbore is okay.
I think this whole "must resleeve" stuff is nonsense, but I dont have any
H22A to prove my point.

 

Honing is just resurfacing the sleeve. You're thinking of boring. The stock sleeve can be bored some before it goes through the FRM, which is an insert and not a coating, but there's been lots of discussion about this before.

JE does recommend honing, but everyone does. They also state very clearly in their catalog that you cannot use JE pistons on stock H22a sleeves.

 

On the H22A4s I have seen I cant differentiate the cylinder liner from
the rest of the water jacket. Can you?

 

There's definetely a darker inner circle on the sleeve it's easier to see if you've had the deck honed.

Like I said, this has been talked about alot. http://www.preludeonline.com/showthr...threadid=48758

There's a load of messages on here as well.

 

OMG, never ending question.
So, no one ever ran a prelude motor with stock sleeves and forged piston? I guess I'll try to get an answer sometime. He don't want to resleeves is because:

1. He don't have another car to support the downtime.
2. He ran out of funds.
3. He don't trust anyone locally to do the sleeving.
4. still money problem. LOL.

I will tell him to resleeve and pull some money out of his ***.

I've seen him on this board. He had an H22A he put forged pistons in and it did lock up. He is the only one I actually know of that toasted a motor because he didn't sleeve the block, but that was good enough for me.

 

the bottom line is, you MUST resleeve an h22 if you want to use forged pistons. if people want to say, "it's not a fact" blah blah blah let them say that. the h22 master himself (Charles Madrid) said you have to. i think he would know.

 

all of you are talking H22A's... this guy has an H23A.

I think someone told me the sleeving was different.... Scott (2point6) wasn't it you who said that? Dunno... I'd do some research before calling it a day though.

 

Yes indeed it's a H23A 1995.
Hoping Honda start the crazy sleeve after 97' but I need to research some more.

 

H23A is the same. I already did my own research before I rebuilt. Check out the sig.
