What year did the h23/h22 come in closed deck form? Looking to buy a new engine, and don't want open deck.

92-96 = Closed Deck
97-01 = Open Deck

 

what do those mean?

Open Deck is a hollow block with the piston walls pressed in leaving a gap between the piston walls and the block

Closed Deck is a solid block with holes for the pistons

One thing that I have been curious about is the weight difference between open/closed deck engines. Does the closed deck make the engine weigh more??

i dont think it's a significant difference, although i'm sure there are a few lb's difference...

 

but just because its open deck doesnt mean that its weak. honda did a few things to make it stronger.

 

So 96 VTECs were still H22a1 with OBD II?
I was under the impression that they had the H22a4 with OBDII.
The 96 VTEC in Japan was a 5th gen whereas here it was a 4th gen.

 

the 96 preludes have obd II but still the same vtec engines as 93-95. 97-01 are the h22a4 and all have obd II.

and r u sure 96 preludes in japan are 5th gens??

 

I am almost positive.....
And 91's were 4th gens
Anyone else???
91-95 4th gen JDM
96-01 5th gen JDM
