Woud this work??
 

I'm looking to maybe buy some Mahle pistons for my H22. Now I know that the bore is 87mm, but would it work if I bought some 87.25mm pistons just to be safe in case my cylinder walls are bored out a litttle. Would the .25mm make a huge difference if the bore was still 87mm. I'm guessing yes it would make a difference and that maybe I should get them measured just to be sure, but if anyone has any other advice??

Re: Woud this work??
 

I've always heard that if you put forged pistons in an H22, you have to sleeve it. Somebody will confirm this or just say I'm a dumbshit.

Re: Woud this work??
 

you cany use .10 over pistons in a stock bore, it would need to be .10 over, but since you cant bore stock frm sleeves, you are fucked out of luck.

mahle pistons are ---- anyways

Re: Woud this work??
 

have fun sleeving that ----.

Re: Woud this work??
 

Why do you say there ----? Any evidence or just word of mouth?

Re: Woud this work??
 

Actually Mahle pistons can be put into the FRM sleeves, if you read up on them you will see that they won't mess up the sleeves, that's why I'm posting a thread about them, because I know that FRM sleeves and forged pistons are a bad combination, but Mahle has a good rep or this. Do you know of any other pistons with a 9.1 compression that would work without having to re-sleeve?

Re: Woud this work??
 

no ---- mahle pistons are for frm sleeves.

do you not read up on h-t? none of the mahle pistons ft correctly they are junk,

and no, you can not bore frm sleeves.

honestly, a stock block h22a is useless, boost it as is, and hope it holds together

Re: Woud this work??
 

I know that you can't bore frm sleeves, I never said that I could, and I don't know why that ever came up. Anyway yeah I did read up on h-t thread and if you read all the posts there was a common agreement that Mahle pistons would work, for how long?? I don't know, but others have used other pistons without any problems. So no I won't boost it as is, but thanks for the advice I guess, very non-productive, but the effort was there.

Re: Woud this work??
 

I dunno silly thought, but it may have come from this...

Re: Woud this work??
 

id like to just throw in from a machinest perspective the sleeves are borable but honostly youd be best off finding a small machine shop and just haveing them sleeve the block any compatent shop will be able to do it also good time to bore those sleeves and have the block resurfaced and acid bathed just a thought

boring frm sleeves .25mm is very doable wether you say no or not its do able at a compatent shop but be carful at such an incrament can be fucked up very easily

Re: Woud this work??
 

yeah im unsure as to why boring was mentioned ::)
the frm sleeves cant be bored dude. fyi.

Re: Woud this work??
 

what are the frm pistons made of cuz if its anything besides stone they can be bored

Re: Woud this work??
 

I had the impression that while reading the thread at h-t that going with 87.25mm might be alright, and well I guess they can be bored...or not. I've heard that they can't and I apologize for being a hypocirte earlier for saying that quote, but do you have any other useful information other than the frm sleeves can't be bored? Don't take it personally I'm just trying to learn a little.

Re: Woud this work??
 

if u dont want to sleeve
the cheapest and safest solution would be to get an f22 block
the u can run forged pistons no problem

Re: Woud this work??
 

would dual cam matter or is it just the single thats cast sleeved?

Re: Woud this work??
 

That's Mahle's third try at coated drop in forgings for an H22.. other companies have tried, too. So far people have clocked 5-10K on these pistons, but - are you feeling lucky over 5-10K miles?

Get the F22 block, you can fit the H22 head and such on it. Requires all the H22 hardware + small bits.

Re: Woud this work??
 

I had an F22 that's why I swapped. I didn't realize what I would be doing to the H22 in the future, instead of using the F22 block I will just get my H22 re-sleeved, much easier as far as I'm concerned

Re: Woud this work??
 

getting it resleeved is fairly cheap a good machine shop can do it for you and bore it to anything you want the will custome bore the sleeves for you the stupid idea that you cant bore sleeves is prolly something that was told to him by some other tool any steel is able to be bored just wether its worth it is the question you would prolly be better off with the f22 block those are a dime a dozen in junkyards i know around here they are

anyway little bits? wtf

Ingram's charges $450, it's $200-250 for Darton open deck blanks. I know people who have saved a buck or two off that price with other local machine shops, most of which it was their first Honduh block and they stated it would be their last, and when their sleeves sank there was no warranty. Dave Ingram stood behind his work, redid Rob Blossfield's D16Z6 (currently residing in my garage, awaiting parts, then 350 whp pls kthx) when the sleeves sank.

I dunno how much overbore you can throw on the open deck sleeves, but they are a good bit thicker than the topmost bit of the OEM units, which means they are waaaay thicker through the body. See the stickied Honduh sleeve info thread chris stuck in the Tech forum. Due to casting variances, it is not uncommon to have the thinnest part of the Honduh sleeve (regular B + D series liners, anyway) to be 0.060" thick, somewhat reinforced by the aluminum block cast around it.


Yeah, well, FRM sleeves stand for Fiber Reinforced Material. It's a punkass, junk ass composite material. We aren't boring steel anymore. Your point stands, but it doesn't mean anything.

Timing belt tensioners, gears, guide, and small bits.

BTW, you aren't the only trailertrash surfing the web.

Re: Woud this work??
 

simple question took 20 replies to get answered (what frm sleeves are) personally id trust a a2 steel sleeve over those just for pure force or a cast iron bored sleeve sure yes it weighs more but you can also boost a whole lot more pressure in them too

but down to the point thanks for answering the question

Re: Woud this work??
 

Sorry if it took a minute. People here ASSume varying levels of Honduh knowledge. Not everyone here is a Honduh owner, or if they are it's recent + they cut their teeth elsewhere.

Re: Woud this work??
 

ive been working on hondas seince i was in middle school this is nothing new to me i still have my first honda 92 accord wrecked it rebuilt it got flammed on by these fuckers and i still dont see y people buy fiber reinenforced sleeves because frankly they are just expensive and over rated

Re: Woud this work??
 

Yeah, but stock out of the box H22 is the holy grail. Best flowing (ignoring K-series stupidity) stock Honduh head, they are pretty cheap these days, and there are a number of people putting near-200 to the wheels with stock H22 intake/header/exhaust. Also the only balanced crank in the H/F lineup, not counting the S2000 which isn't a real F-series...

Oh, yeah. This is HMT. People flame the ---- out of other people for absolutely no reason whatsoever - it's a time honored tradition in these parts. Get used to it, fuckface :P

Re: Woud this work??
 

not my style im all bout makin people sound stupid

Re: Woud this work??
 

Make them sound stupid, then add a fuckface at the end of the sentence. You'll fit in just fine.

Re: Woud this work??
 

lol i fit in just fine anyway i dont say a after every sentance and my closest neighbor isnt a cow
fuckface
