Bullet Proof H22 Block Build
As the title says; Im interested in building an h22 engine to handle high boost and run race gas when needed. I've done research and know that the ringlands and the cylinder walls on the h22a4(97-01) are weak and in order to have a suitable motor to boost safely and reliably, the engine block must be sleeved and fordged internals must be put in.
I further looked into the deck design on my motor, a 2000 h22a4. It has an open deck design which has the thin sleeves free standing in the cylinders. As I've heard, having an open deck is not a prime choice for high boost and would be better with a closed deck. The h22a1, found in the 92 - 96 2.2 Vtec Preludes are closed deck.
Now, to build a so called "bullet proof" block, would it be better for me to purchase a h22a1 open deck block, sleeve it and build it? I've heard that it doesn't matter if the block is open deck or closed deck, as long as it is sleeved, built, and tuned properly, it will be fine. But im lookin to build a very strong and reliable block for a turbo application.
Which would be a better choice?
Any information on open deck/closed deck blocks is needed.
Any information comparing the h22a1 and h22a4 in boost applications would be helpful.
Thanks.
