Is the b18a open or closed deck? - Honda Forum / Acura Forum

Hey guys, I plan on eventually going turbo with my car and I was going to over bore slightly and get some new low comp pistons. So what I wanted to know is the 90-91 b18a open deck? If so I plan on using a block gaurd or whatever it is called to support the cylinder walls.

every b series is open deck. pretty much every honda engine is open deck with the exception of a few.

Yeah, I think every Honda engine is open deck, as Snoopy said.

Don't forget about the H series engine which has a closed deck block.

EDIT: My mistake F series is Open Block

No and here is proof of an H22A

Hmmmm....I will do some research to find out which ones were open and closed

From what I have found out (other sites "Says" but no pics) the H22A1 is closed and the H22A4 is open. I will try to find pics but this just proves to "Mr GSR" that not all Honda engines are Open Deck.

No flaming intended...

I know for a fact that there are open and closed deck blocks. I wouldnt have asked if there was only one. but thanks for the replys.

One of the H22 models was open deck and one of them is closed deck.
