I was talking to a darton sales person, and i was asking them about the sleeves... I wanted to know if the sleeves are different between h22a and h22aX (jdm vs usdm) since they have open and closed deck blocks.

They said nothing was different, but i am assuming there is. I was asking for the specific part number, but they wouldn't give it to me. Then they just stopped responding...


So my question is...

Is there a difference in replacement sleeves between jdm and usdm blocks?

What is the part # for my specific block? (h22a - Closed Deck - jdm)

 

There shouldnt be a difference in the sleeves themselves. And even if there was it would get fixed up when they fit them.

 

--- flanged and unflanged is what I was concerned with.

 

well went on their website, they have flanged and unflanged replacement sleeves. whoops on my ignorance.

 

IIRC, the flanged is the heavy duty MID sleeve. The non flanged is a dry sleeve. I run the dry sleeves in my h.

 

When you sleeve a H22 block whether it is closed or open the sleeves are the same. Depending on how much power you plan on making and how big a bore size you are going to run will determine which sleeve you will use.

If you have the H22a/a1 closed deck block and this is going to be a strip/street motor you can use the 300-018 sleeves for stock bore size. If you plan on building a straight drag motor and going with a large bore then you would use the MID sleeves.

There are acutally 3 different sleeves for the H22 blocks:

1. Repair sleeve 200-018. This is a straight sleeve primairly used for stock applications or to repair the block.

2. Flanged sleeve 300-018. This is a flanged sleeve with a lip at the top so the sleeves registers at the top for added support. This sleeve is good for mild horsepower builds street/strip.

3. MID 400-160-P. This is our phosphate coated MID wet sleeve. This is the top of the line sleeve that will handle anything you throw at it. Since it is a wet sleeve the sleeves are completely replaceable one at a time or all four at a time using the same block. This allows you to use the same block over and over again. The sleeve is also phosphate coated to help with anit-rust and anti-corrosion in the water jacket area.
