ok i found out that s2000 pistons and h22 pistons are the same bore size, but the s2000 pistons are forged, now JE pistons says that you have to resleeve the block in order to accept forged pistons because of the fmr coating on the cylinder walls , but the s2000 pistons have the same fmr coating, so what i'm thinking is using je pistons with s2000 rings ?? any thoughts on this


please i need some other opinions


btw i have a jdm h22

why not sleeve it anyway so u can have more boost?

 

money

i'm trying to innovate a way to get around sleeving it

 

do a search there is a thread about 3 pages long about this

 

my respone to u would be don't try and innovate just sleeve it...your asking for problems... I f u don't have money to sleeve it then you shouldn't be doing whatever your doing...jst wait till you can do it properly.

ok let me explain something i know about sleeveing i know its important but i don't want to boost 15psi i just wanna boost like 6-8 safely and the only problem with the h22 is the ringlands on the pistons ,now i have heard stories of ringlands busting on h22's w/o using n20 or boost ,they are just weak bottom line,and if no one innovated new ideas then half the things around you people would not be here, i'm sure if everyone had that mindset then there would be no ls/vtec motors everyone would just say "just go by a gsr"

 

Good point, i totally agree with you trying to be innovative, but i really can't help you on your question. I read in the other thread that they were comparing the rod lengths and some other things. Some said it isn't possible, while others weren't sure. Check this thread https://honda-tech.com/zerothread?id=341230 Hope this helps some.

 

thanks for the link i did a search and came out empty handed thanks alot again

 

Go to swain tech and have some forged pistons coated with the thermal barrier (to use stock clearances) and the dry film lubricant for the side (skirts). The rings are not the issue, it is the skirts and the extra clearance galling/gouging the cyl walls.

 

So does the thermal coating definitely solve our problem with forged pistons? If it does that would be a great alternative to resleeving our blocks. Thanks for info. Also do you know how much it costs?

 

It is more the friction coating on the skirts than the thermal barrier, but both will be best. The cost is @ $130 for all four, but that was a few months ago. Give them a call, they guarantee their work and have much experience....

I am beging to think a work around has been found to the whole sleeving issue.

Sorry to bring the post back from the dead...

 

Honing is key in addition to the coating on the pistons them selves. (at least every thing I have read has said this.) Check this post here https://honda-tech.com/zerothread?id=416069 and then this one here http://www.theoldone.com/forum...11980

 

i read somewhere that h22 blocks cannot be honed conventionally, that you gotta take it to a shop and have it done specially? I'm usually wrong though. Anyone know?

 

I have heard that Wiseco or someone else makes a piston that utilizes a small skirt area on the piston. I think that is one of the remedies for the forged piston problem. Maybe someone else more familiar with it can give us some more insight.

 

blah blah blah blah blah...... this damn topic again, jezzus people, use the search button

 

it's a valid topic though. and i find it very interesting. some pretty good material is displayed here too.

Isn't the archive search down. Don't like the topic, don't post.

 

Here is a message I wrote to Wiseco in regards to frm lined cylinder walls and forged pistons.

"I have heard a rumor that your company is now producing forged
pistons that are compatable with the frm lining found in some honda motors. I am wondering if there is any truth in this, and if there is what changes are made to the piston that make it compatable? coating?
Also what applications would these pistons be available for?
Thanks,
Jeff Schluter"

and here is their reply--

"Jeff, yes we've been selling quite a few of our h22 pistons with no reports of problems w/ the stock 87mm bore. The skirt shape was hard to derive, but we think we've got a winner. I don't mind recommending Polymer Dynamics skirt coatings as well. Just an added measure of protection. Their number is 713 694 3296. They sell pistons at Jobber price w/ their coatings included."

I remember reading some where that they had changed the skirt shape based off of the pistons in the s2k, but I didnt wanna base my info on what I read in someones post. So I sent them a message myself (this is a repost I made off of Preludeonline from a month or so ago)

Thank you for taking the time to find out the answer and putting an end to some of these people bitching about this topic. Glad to hear you guys have a cheaper alternative to resleeving.

if the questions is asked weekly, don't ******* ask it again

go ahead and don't sleeve, see how much boost your **** holds

 

whats your problem ? People come to honda-tech to ask questions. Grant it they due get a bit redundant but people always come up with new solutions and the search button won't bring that up. Calm down.

fine, he can try not sleeveing, but regardless of whether this uses forged psitons or whatever, the stock sleeves will not hold boost..... he will be pissed once his stock sleeves **** up and **** up his forged pistons, then he wil have to rebuild again, this time sleeving, and having to buy new pistons

thank you, i know nothing

 

How much boost are we talking about? 1 bar daily, then yes I agree he will definitely **** his sleeves up. But if he keeps it under or at 10psi with the ocassional spike to 12 I doubt that would happen. Also motors get fucked up because of driver error, ragging the **** out of it. That is a major contribution. Don't boost if your gonna careless and cheap. If you spare no expense then boost the hell out of the motor. I guess I dont know anything either . Thanks.
