Is a Jdm H22a open deck or closed. I tried using the search fuction but it never works

 

i believe it is open deck like the usdm.

 

i've read different, just cant remeber where. anyone with a jdm motor want to verify whether its closed deck or open deck?

 

I could have sworn that someone said 97 2001 was open and before that was closed but I'm not sure. Thats why I'm asking you guys.

 

I have a 93 jdm and it is closed deck. I believe they were all closed deck up to 95

 

pretty sure its an open deck

 

Closed.

 

This is confusing. Everyone contridicts everyone.
I ask becuase I am buying some darton sleeves on groupbuy****** and when you go to check out it asks you a couple questions and one of them is open or closed deck. Also it gives the choice between long and short sleeves. Which one am I supposed to pick.

H22a1 = closed deck
H22a4 = open deck

I believe this is the same for USDM and JDM spec.

 

anything from 91-95 is closed deck Jap spec or USdm

anything from 96-00 is open deck jap or usdm.

also the japspec heads has dual springs on the intake side unlike the usdm. which is only single spring.

 

True dat!

 

JDM engines are typically just H22A, but i oudl think that they would be the same as the USDM, 92-96 are closed, and 97-01 is open

 

The jdm and usdm 92-95 h22a are closed deck and 96-up are open. I have a 95 h22a and it's closed deck. The only thing i think people are not too sure about is if the 96 is open or closed.

 

96 is closed. All H22A1 are closed.

 

what do u mean by deck?

 

Sweet. Thanks guys.

 

for reference, this is an open deck from my 97 H22A4 Prelude engine

and the deck is the top of the block

 

thanks for the visual Sam.

 

not a problem, i knew i had that pic somewhere

 

I think all JDM H22's are closed deck. But I may be wrong.

 

does anyone have a pic of a closed deck block just for visual comparison? i knew what the definition of both was from hearing people talk about it, but i had not seen a closed deck h22 before because i have a 98

 

now i have the 94 jdm h22a and it IS closed,( obd1 closed, obd 2 open), i was wondering can you still sleeve it, and is it different than sleeving an open deck?
