i was told theres a certain coating or what not on a piston that would allow me not to have to sleeve my block. is this true?


also are the h22a4 and the h22a pistons the same?

 

why would you have to sleeve your block?

 

putting in aftermarket pistons

 

If you want to use forged piston, the only ones that will work with FRM are the Mahle Goldseries.

H22a uses press-in pins. H22a4 uses floating pins.

 

you may want to search mahle on here though. there are lots of reviews. some are information. others comment from word of mouth without experience themselves. use your judgment. type s pistons work as well. if your boosting more that 8lbs or so or plan a NA build on running forged pistons with higher or lower compression, doesn't matter, then you'll need to go ahead and spend that 1k. better to spend the grand than to spend 2-3k trying to fix what you screwed up.

 

Don't post anything if you don't know what you're talking about. The Mahle Goldseries pistons come in 9.0:1 , 10.0:1 and close-to 12:1 . There are plenty of people using them in forced induction applications, and there have been people who've used them in NA builds as well.

And 8lbs boost is an arbitrary number that has no significance outside the context of turbo size.

 

im useing mahles but there for sleeves, but i have ran the goldseries there great in my opion

 

Did you sleeve the block?

 

wtf are you talking about dude. i never said they didn't come in different compressions. nor did i say they can't be used in NA or Turbo. I know they have different ratios for different apps. READ my post again. i simply said he my want to do research. and i have researched mahle for the past two years because i too wanted to skimp out on resleeving if i didn't have to. but its better to have insurance and resleeve. end of story. so don't tell me i don't know what i'm talking about. you want to read a person's post 2-3 times before you try to call them out.

as far as the 8lbs. i also said 8lb or so. i didn't just say 8lbs. you need to account for tuner error on a stock block. not all tuners can give you a lasting motor. the more boost, the more stress your motor is taking. i may not know 100% everything without having done this stuff but I have researched sites over and over for as long as I have been a member on this site alone. i don't just post for the hell of it. i post what i have read else where and what i have gone thru and try to spread the knowledge.

 

Are you so stupid that you can't even comprehend your own post after the fact. Read it below, it's all of what you wrote, broken into paragraphs. Pay attention to the bold text.

8lbs? Where is there is anything about tuning. Even if there was, what would that have to do with anything. Tuning is important regardless of sleeve material. And it's the stock cast pistons' ringlands that are the problem. In the end regarding your post, 8lbs is still figure that has no meaning whatsoever within the context of your post.

There's no question of insurance if people have no problems with the pistons. Spending an extra $1,000 if you're not looking for the .1L+ extra displacement is foolish. And beyond that you'd give up the advantages of FRM.

As you said, you don't 100% know what you're talking about. So don't give out advice on false premises. It's people like you that ruin good forums.

 

So my CR is going to be about 11:5.1, I'm not sleeving and using oem type s pistons, am I in trouble?

 

Why is it over 11.0:1? Thinner headgasket, milled surfaces or flat valves?

 

type s pistons, H23 bottom, H22 head. (H23vtec) oem head gasket.

 

look here you lil 15 SOB. apparently hooked on phonics is to advance for you. not only is the word stupid offensive to me but the whole post you even started. lucky for you this is the internet because its people like you i've love to kick their a$$ just by saying offensive crap. i don't know you, you don't know me. calling me out isn't tolerated in my book. obviously you could not break down my run on sentence. so I will break it down just for you. what I was saying is:
if your boosting more that 8lbs or more on a stock block. or plan on a NA build running forged pistons no matter the compression, then you'll need to go ahead and spend that 1k and resleeve. better to spend the 1k than to spend 2-3k trying to fix what you screwed up.
now if you can't under stand this break down them let me have some of that what your smoking. I always wanting to know what it was like on the moon. and with this I am done. your pointless agruement is taking away from the OP. just because you have 5k+ in post don't make you any better than myself. it just means you don't have nothing else to do but be on here. post ***** or what not.

to the OP. check this thread out. https://honda-tech.com/forums/showth...resleeving+h22. this was one of the main threads i spoke of to come to your own decision. install error may have a part in some failure stories which is why i said research.

 

if you use the 10cc NA pistons make damn sure to check the piston-valve clearance. The set i tested way back in the day was wrong and the replacements they gave me were wrong.

as far as working in the stock sleeves, they work awesome and have a good ring pack.

 

what does PSI have to do with pistons and sleeving when you dont know what turbo is being discussed?


PSI is irrelevant when you dont know the turbo being used.

 

you don't know the turbo in mind either. the turbo wasn't listing so I am speaking in general. no i don't have experience with a boosted motor. no i do not know 100% when it comes to the subject. the bottom line i am getting at that I am telling the OP is to research. from my research on here no turbo was listed and the advice that was given was to resleeve a stock block once the psi increases in order to give margin for error in tuning. what if one upgrades or just changes turbos altogether. why not just sleeve from the beginning and call it a day. if the sleeves are turbo depended then my bad. i learned something new. all that had to be done was I be corrected. no need to call me out. that would make the name caller the person to ruin good forums. and based on my responses to defend myself I would be included for this topic.

 

here are a few threads for the reading. i have read alot of PrecisionH23's post in particular when it comes to boosting and i believe in what he says.

i will stop it here. go tell this people they are stupid for their post years ago. if you wanna flame me for what I read. and yes i am aware that products get better over time. some of the post above refer to the stock piston but if they are not forged then why risk your investment.

 

I'm not the one who said 8psi is the bottom line for block sleeving.....so no, in general, what you said still does not hold water.

 

Have some humility and be man enough to admit when you're wrong. You come off as more foolish each time you post.

The engine that Anthony tore down had no documentation of piston-wall clearance, and he didn't know either. Jdogg has done many builds using these pistons without problems, as have many others. Here's a 33 page thread dedicated to these pistons in the FI forum. Many people in there with high output engines using these pistons and no problems.

Hey 92 civic lx. Why do you want aftermarket pistons? Are you going turbo or do want a higher compression ratio?

 

i already stated that i didn't know everything when it comes to the subject, so there is no point of admiting to being wrong. I am here to learn just as others. and to be corrected just as others. you just don't know how to politely correct someone or for that matter elborate/clarify information without jumping down their throat. and the mahle thread you posted is the same one i posted in a previous post. i followed that thread religious daily until it got to 20 something pages years ago. i never said they didn't work. i just want the OP to look into what he could be dealing with. JDogg can't account for all failures for the pistons or the install. Not everyone will have him or a person that knows how to make a boosted h22 last on stock parts.

 

I'm pretty sure he's wanting to turbo it
