I skimmed through some of the old forums but i still had some of my own questions concerning my H. I have a set up of an H22a1 with Aem fuel rail and regulator, skunk 2 intake manifold, blox 70mm throttle body, high performance valves and retainers, stage 2 camshafts, skunk 2 cams, walbro 255 fuel pump. I was wondering if i run a turbo at 7 psi would it affect my stock walls? Plz give me ur opinions. Thanx
Yes, what would happen is your rings will fail. The boost would cause the rings to press harder on the cylinder wall, and possibly scar it.
However, not long after, your rings will fail and your engine would be effectively ruined.
If you want to boost a prelude, you need stronger/different rings, and forged pistons would also be a good thing. But in order to have either of those, you need to resleeve the cylinders.

can u give me good websites to which i can buy pistons, rings, and sleeves at a good price? If I was installing turbo would i have to lower the compression also???
actually an h22a1 is in the 4th gen VTEC lude so that would mean running Mahles is a BAD idea because the block doesnt necessitate for FRM. Its not your walls you need to worry about, your motor is strong and closed deck. You need to worry about your rings.
If I were in your shoes I would do a compression test to determine if you have poor or bad compression, a sign of bad rings. If not, boost at 7 PSI on an all stock motor. No need to spend all the extra money on internals if thats all you are looking at doing.
The company "Golden Eagle" out of California can do everything you need to your block. Just tell them the specs and they supply and install all the parts. They have their own sleeves, pistons, rods and machining equipment. They install it professionally and give a warranty with it too. It will cost a little bit more, but a warranty is more than you can say for most companies out there.
Also, just because the H22A1 is a closed deck, doesn't mean you still can't sleeve the block. Golden Eagle also would know how to do this.
Open Deck: The area between the block and the sleeves is "open" meaning coolant can circulate around the whole area.
Disadvantages: high pressures might cause an increased likelihood of destroying the thin cylinder walls, because those 7 or 8mm is all you have between the internal combustion and the rest of the block
Advantages: increased cooling due to more coolant allowed to circulate thru block as well as increased capacity of coolant
Closed Deck The cylinder walls are simply bored out of the block. Then coolant passages are drilled or cast in around them in symetrical fashion to allow for coolant to circulate thru the block
Disadvantages: Heavier block overall, decreased cooling efficiency, harder and more expensive to "sleeve"
Advantages: Stronger because all internal combustion pressures are dispersed throughout the whole structure of the block. Usually can bore out the cylinder walls more than an open deck.
I would recommend against using Golden Eagle. They are expensive and you can get the same thing, or better, elsewhere. Also the warranty is on the block and not the tuning so it doesnt mean your motor is covered. You will be covered against sinking sleeves and thats about it.
I am confused why this thread turned into an engine build thread and not answering your original question. If you are looking at an engine build you just increased your overall cost by 3K-4K.
Do a compression test and if it all looks good boost it stock.
I would also recommend reading my sticky thread where I posted pictures of my engine build and go through on how to build a motor. It will answer your questions.
Driverz, you need to tell us what your budget is and what your goals with the build are. Be very specific when you do it too. Your vague questions will only get vague answers in return.
Then we can all decide how best to approach the recommendations on your build.
I think somebody like pEIRCE or Kronn said this to a newb before when he was asking about a turbo, but don't give us the PSI rating you're looking at, because not all PSI's are created equal. It would be better to give us a HP number to achieve and from that we can tell you which turbochargers to look into and what PSI they can run and what you should be running.
