h22 open deck and closed deck
i have an h22a1 (usdm). is it open deck or closed deck? i heard of issues where the closed deck (the one that doesnt cool as good) blew even on low boost (7.5 psi or so)
i plan on doing low boost (6-8psi) on stock internals (no sleeves or anything) using a dsm 14b turbo. will i have a problem with cooling? will i run into any problems with such a low boost?

Re: h22 open deck and closed deck (95hprelude)
yours is a closed deck and it will have no cooling problems even at higher boost. The only reason that honda changed it over to a open deck is that it is a quieter motor.

They're also 600lbs heavier and the sleeves are made of mahogany wood. As long as you dont rev past 3500rpm you should be fine with the H22.

dont listen to this guy, he has no ******* idea what he's talking about, the sleeves are made from royal oak. as for the rev limit, i've peronally seen solid deck blocks run up to 3871 rpm's with two blockguards.
hope that helps

Re: h22 open deck and closed deck (95hprelude)
they're joking...
you wont have any problems running a closed deck block on 6-8lbs, just make sure you get it tuned by a reputable tuner...

See other postings. with lower boost that you listed, you can rev to same limits as stock. A good tune is important.
Maybe three block guards and the Balsa wood liners?

so there is no difference as far as boost is concerned between the opened deck and closed deck? i thought i read in sport compact tuner under the h22a CRX swap article that the h22a4 was the more preferred engine of the 2 for boost applications

Re: (h22a_junkie)
I "heard" the closed deck version is better for boost somehow. I think the liners are held in place more so by the structure of the block than on the open deck but dont hold me to that.
For turbo your best of with a T3/T4, Precision SC-61 or T70 but expect a bit of lag on the last 2, again only from what ive read. Im starting off with a T3 .AR 60&48 to get me started then im swapping out to a SC-61 or T70.
Good luck

The only time you really need to worry about the difference between H22As is when you're building a hardcore setup..
Honda went with larger mains and open deck on the newer H22s (but i think there is an oddball year?). This might appeal to people who are looking for crazy whp #'s or very high revs, not to the average joe who wants to burn some rubber.
Choosing a turbo is easier than most people make it out to be (I've been there too!). Just see what works for other people and go from there. With enough searching and googling you'll find someone with a similar budget.
Rudelude, there's no way an H22 can rev to 3871 without Year2000Motorsports.com African hardwood replacement sleeves, helium filled pistons and welded exhaust ports.

Ive actually had better results with the Neon filled pistons vs the helium filled. The higher atomic weigh of neon results in a more stable structure, which will ultimatley hold up better under boost.

Re: (Semnos)
ok, if you put a 14b on the H22 it will be BARELY faster than stock. a 16g is also o small for an H22. the smalles dsm turbo i would use (because im sure ur using a stock DSM manifold for this) is a 20g. but seriously, you have hondas 2nd biggest vtec motor. use your displacement. get a big turbo and make some real power

Re: (95hprelude)
lol, u guys crack me up...on a real note though, i have an h22a solid deck, i'm boosting with an sc44, 8psi, tuned on uberdata, i havent dyno'd as yet, just street tune, but i dont think i can squeeze much more that what i have now, i would say it putting out around 300whp. feel sick as hell, i'm getting a set of mahle and eagles and upping the boost, if i'm not happy i'll get the sc61 s cover...everything is stock in my motor right now, for like 6k miles now, always romped on, never had a prob.

the h22a1(92 - 96) is a close deck motor. The h22a4(97 - 01) is an open deck motor. Open decks do cool better than the closed decks due to the open deck's coolant jackets being exposed, but the closed decks are a bit stronger because of the extra mass around the cylinders. If your not going with a crazy setup, open deck or closed deck shouldn't matter. In the case of a high boost/horsepower setup, the closed deck will hold higher boost but the downfall could be cooling. If your serious about a build up, dont skip on anything, motor, turbo kit, suspension, cooling, tuning. You must do it all right. There shouldnt be a problem though if your just looking for "small" power. Eaither way, if your looking to build your h22, sleeve it, build it properly, and tune it. Your setup is as only good as the tune. Do it right the first time. Until then, learn as much as possible.

Re: (Slick00Lude)
my plan is to piece together a turbo kit. i think im gonna use the stock evo trubo (16g i think), stock evo manifold (needs to be redrilled, but the ports line up perfectly), and a stock evo intercooler.
my inspiration -

just w/o the anti-lag

I ran a stock h22a1 for a while on 20 psi with my sc61.... motor holds fine.. just have to be conservative on the timing.
