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

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.

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

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

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.

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

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 *** 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.

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
