MAHLE gold series pistons...

[h22accordaz]

Ok, so I was just wondering if anyone has the MAHLE gold series pistons in their H22 or has heard anything about them... They claim that you don't need to sleeve the block with these pistons. I just wanted to know... Thank you in advance. Later...

Here is a link if you need it, or just want to take a look.

Does this mean that nobody knows anything about these pistons? Thank you anyways...

I have heard of pistons with a special coating to allow them to be used in H22/H23 blocks, but I have not heard of MAHLE specifically.

I know Dave @ www.dh-racing.com has pistons with a special coating that will work on H22s. Contact him if you want something with some background on them.

I'm in kansas and have an h22 in a '90 LX w/type S cams and coldair. I plan on boosting it and i talked to the head guy at mahle. he claimed theres guys running 15-20 psi no problem without sleeving the block. I plan on using them, great for a budget build $500 retail.

Mahle is actually a pretty well known name, I'm suprised you don't know of them and their products.

They are more of a domestic manufacturer though, not to into imports.
I do plan on using them in my h23 with some econo rods and go for 300 hp.

Probably because they don't make anything pertinent to me. I'm "zoned" in on my projects

Well I just took a quick look at that site and didn't see anything about a coating on the pistons... WHich number do I call to talk to him? Thank you..

mahle pistons are realy good. they come out of the box with a ceramic coating, and they are the only company that gives you performance piston rings withe the pistons.

i am also suprised that you havent of mahle. porsche uses mahle pistons in the engines. cart, fia world rally, dakar rally, formula one, and so on. mahle is a known and proven piston. i will be using mahle in my engine build.

I'm just hesitent to use a piston in an h22 without sleeving it... I know you have to sleeve the block with any other forged pistons so im hesitent.. I take it nobody actualy has these pistons though? I think I am going to get the 11.5:1 pistons... I will let you know how it go's..

^^ if you are using 87mm bore pistons (stock sized) then there is no need to sleeve the block what-so-ever.. why would you have to sleeve the block.. just because they are forged pistons??

that doesnt make any sense??? although yes a boost application is entirely different since heat and pressure are critical..

only pistons that are over-sized.. say 20thou.th's need boring of the block.. which when it comes to h22a's would be a good idea to change to full iron sleeves.. since we all know the stories about the older h22a sleeves.. and their fibre-reinforced layer approx 0.5mm from the sleeve face.. etc etc..

i currently have SRP 87mm 11.5:1 pistons ordered... no machine work required here...


and for whoever said MAHLE is the only company that sends (performance) rings with their pistons.. is wrong.. any major company, like, JE...WISECO... ARIAS.. can be ordered with or without rings.. it is the customers choice..

our shop orders in pistons frequently.. direct from whichever company.. and always recieve rings with the pistons

Whoa there cocky member, cool your jets... There is nothing here that required you to go into defense mode... I have heard from MULTIPLE people that because the h22 has fiber reinforced "sleeves" that you have to re-sleeve the block before you put any piston in besides stock... Apparently I'm not the only one that has heard this because if you take a look at the link I posted a DIRECT quote from the site is;

"It's another MAHLE technological breakthrough! This is the ONLY all forged, aluminum piston for the Honda H22 engine that does not first require sleeving the block."

So don't come in here acting like you are a mister know it all and we're stupid... You could have posted your helpful info in a good way, but instead you got all defenseful...

???.. how was i being defensive.. because im correcting you?... just that you stated in one of your original post.. that you CANNOT install forged pistons without sleeving the block which is a false statement...

im not acting like a know-it-all.. wtf.. does everyone have to get all (HEY COCKY MEMBER BLAH BLAH BLAH) when someone actually has an educated idea to add to the thread.. wtf.. ?
