My thread got locked and i really would like some info...

https://honda-tech.com/zerothread?id=1603407

Has anyone done it yet? or did they put there pistons in after they got it bared?
i'm building my block and i was curious if i would pass with lower compression turbo pistons on the h22a? 87mm bore.. unsure what ratio but could i pass the sniffer test? and if i wanted to go n/a what kind of pistons could i use that would still pass the sniffer test?


the block has been resleeved by golden eagle at 87mm. i just want to kno how much will it effect emissions testing.. i kno i will lose alot of power with lower compression pistons and not being turboed yet.. i just want to build the engine and get it bared with it already having the turbo pistons then turbo it after getting it bared...

and i'm doing this because the engine is in pieces and i want to get new pistons and rebuild it etc.. with.. either turbo or stock pistons.. but i would prefer turbo.

 

search my friend there are hundreds of threads on here about things like this

key:
stock sleeves:
Mahle pistons

Sleeved:
cp
j/e
etc

 

SO lets make another thread about the same SUBJECT

 

my question is will i still pass the ref if i had turbo pistons in the h22a? when i try to get it bared.. or will i have to stick with stock pistons..

how much would lower compression pistons and higher compression pistons effect my emissions test?

if it does effect the emissions test what compression would be best to be at where i wouldn't have to worry too much about the emissions.

Are you trying to say Bored . BARED ???????

He's talking about emissions.

Answer: Do it right, get it tuned, and you probably won't have problems.

/thread

 

im glad someone could read that jiberish

 

thx.. but i can't chip the ecu when i get to the ref.. i already have a p72 ecu with uberdata but i can't use that ecu at the ref.

so will i be fine with emissions even though i'm using the p13 usdm ecu and aftermarket lower compression pistons?

there has to be someone that has tried this.

 

go with Mahle pistons be they are the best

 

u must have editted the original post cuz its pretty clear what you are asking now, otherwise people in this thread so far are complete dumbasses since it clearly says IT IS ALREADY RESLEEVED....but i dont know what the original post said

anyways...

usdm is 10:1, people easily pass with type s at 11:1, im guessing youre going somewhere around 9:1 for the turbo setup, with the lower compression you will only have a problem with HC, no one can really say for sure if you will pass, as things like leaks in the valves or rings arent known, u will most likely pass the sniffer at 9:1 with all sensors functioning properly, the cheapest way for you to get close to 10:1 with the 9:1 pistons is to run just 1 or 2 layers of the headgasket, this should get you close to stock compression, hopefully taking care of the possible unburnt fuel that could result from the lower compression, then once you pass, pull the head and replace the headgasket with the stock 3 layer to bring the compression back to 9:1, this will only cost you an extra $60 for the HG you will be modifying, assuming you can pull the head yourself, honestly though, i would just assemble it normally and try with the 9:1, i dont see you failiing at that compression, from 1-3k rpms, i believe the h22 and f22 ecu would give the same amount of fuel at partial throttle even though one is at 10:1 and the other 9-9.6?:1

good to see someone answer this question and actually know wtf they're talking about

 

YAY!!! I bored my block out to 87.25 mm and I'm now running 9.1:1 Mahles. Compression test results ran 160-165-160-165.

Are you on drugs

Okay...I talked to the tech from MAHLE and this is what he told me. You cannot bore the H22A block out any more than 87.25 mm. Once you do, you break into the reinforcing fibers in the cylinder walls. The reason MAHLE makes an 87.50 mm piston, is for sleeved applications. I've ran these pistons for well over 8,000 miles and my compression numbers have been consistent. However, I'm not boosting until early-mid July, so keep in touch.

As far as "pass", WTF do you mean. Pass emissions, pass inspection?

he means passing the california state ref, aka the bar, aka the bureau of automotive repair, aka the cali agency who determines whether your swap is in your car legally or not, the question was whether he will pass this with 9:1 pistons, why there are so many random posts from dumbasses talking about mahle pistons and going "wtf is the bar, u mean bored" is beyond me

 

THANK YOU SOOO MUCH.. that clearified alot.. and yeah my original post stated didn't state i had it sleeved.. but they didn't understand that i wasn't asking what pistons to put in.. but if i would pass with lower compression pistons..

thanks for the help.. i guess i will go with 9:1 pistons.. now i have to decide what to go with.. and the 1 or 2 layer gasket would increase my compression closer to 10:1 right..what should the ratio end up being with the 1 layer gasket? do u have any gaskets that u could recommend? and the whole engine is in pieces at the momment since it just came from golden eagle.

and if i went the other route and go n/a whats the highest compression u think i may be able to pass with it? since 11:1 seems to have done it..

remember im saying you will PROBABLY pass with 9:1 or 11:1...every engine is different, you could just go with a honda headgasket and remove 1 or 2 layers, thats what most do, as far as highest compression, i would say 11-11.4:1 would be the highest, otherwise you will need tuning or you would have to adjust the timing way beyond +/- 2 degrees, both of which would fail you, if youre going N/A you will change you cams at some point, so i say 11:1 pistons right now with stock headgasket, pass the ref, then yank the head for springs/retainers, 1 layer headgasket, put back together with your choice of cams, and you should have 11.7ish:1 compression ratio, but CLAY THE MOTOR when using &lt;3 layer headgasket and aftermarket cams...
