H22aAccord

I just swapped a jdm closed deck h22a in my accord, its gonna be boosted but it will be built before i go turbo. For you guys out there running boost since its closed deck should i change the sleeves to darton iron sleeves of just leave them alone. someone told me the forged internals will rub on the aluminum sleeves and scrape them up, so who better to ask then people running boost on their h22a. How much boost are you guys running and what if any internal work do u have. I appreciate the help.

stock bottom end is good till about 270 WHP. usually thats around 5-8 PSI. There are people that run more and get away with it but IMO its not worth it. There are lots of people running around that blow their engines in the 270 WHP area. BTW its the ringlands in the pistons that are the weak link. if u resleeve the block u HAVE to run aftermarket pistons. U cant do one without the other on the H22A its not like a B series. Do some research its been talked about alot.

u can use wiseco pistons in stock h22 block. they have 8.5:1 and 11.25:1 c/r's.

from my understanding aftermarket pistons will not work with factory H series sleeves. I believe its the material used in the sleeve casting. Do some research on it, but I read it somewhere.

i have heard of people getting coated STOCK BORE piston to work with the metal matrix material cylinder walls in the H22, but i've never actually seen it done.

we use thicker(.125wall vs. .093wall stock) replacement iron sleeves on 92-95 closed deck H22's and have run 500+HP on them without a hitch.

i personally have pushed the limits of a stock opendeck 1998 h22 with 404wHP at 15lbs of boost. motor is still good and i'm in the process of taking it appart right now to see how the internals look after the 3+years of beating i gave it.

i've heard the weisco pistons will work with the stock sleeves, buti have yet to see proof, i was told by dpr east that they could be ran, but they won't give me any type of like insurace or gaurentee if i did it, even if i let them assemble the block and everything, so when i see some one put about 30k on a stock h22 block with forged pistons, then i'll believe it, words don't mean **** on this topic this requires pictures and proof

what kind of sleeves are you using? i was looking at the darton sleeves

Honda_Tengoku

dartons are usuall the sleeve of choice. Although i just had a friend that built his H22A engine with Midway sleeves (cheaper alternative). Supposedly these sleeves are as strong as dartons but quite a bit cheaper. He hasnt gone above 8 pounds yet, but so far the engine runs very strong after 3,000 miles so i guess we will see.

Dumbass, try reading the post before posting it up!

If you read on throughout the entire post, the guy eventually discovers that the pistons DID eat the block! Not one person to date has actually ran a forged piston in a stock H-series block for a decent amount of miles without the block being eaten.

The stock H-series block can on average take up to 300 WHP before needing to be completely rebuilt.

Gonna run more than 10 psi? Gonna be resleeving.

so pretty much all i need is the darton sleeves themselve i dont need to red deck it right.. And which darton sleeves, the repair sleeves or replacement sleeves??? They are both made out of the same material

This One

The open Deck H22's came with FRM sleeves, cant remember if the closed decks are or not. I thought it was just the Open decks that allowed them to get away with thinner sleeves hence the use of them.

Wiseco apperently offers a Piston that will work With the sleeves as Does JUN i think. I dont think they are off the shelve pistons though or they're readily available typical h22 piston. Seems most people are still skeptical on even using them beacuse of a lack of info or positive feedback

I Remember a thread a few months aog, someone threw a stock h22 in their race car temporarily and it Made a good 500 whp or so If my memory serves me right.

The sleeves arent really the problem either way. The ring lands are very weak.

it's all h-series that have the frm. dont get the replacement sleeves. get the ones meant for boost.

if you'd actually read through that you'd see that i was in that conversation, try not being ignorant

TEZTnTUNE

you've been running 15 psi on your stock block h22 for 3 years?

H22aAccord

Darton offers two types of sleeves, repair sleeves and replacement sleeves, i will go and get the replacement sleeves, they seem to be a bit thicker.

flip1199

dont get the replacement sleeves. they are not meant for boost. when i called darton and asked them about the replacement sleeves they said they dont recommend boosting over 14-15lbs on them. you want the mid kit i believe

hey smartie pants, do a search for a member on here d98clturbo i think it is, he's been runnin this setup for more than a year now, with 15psi, something like close to 20k miles, and he's fine. and also, if u read my post u would see that i said there are a few members in that post that are runnin the set up. there are people in that post that are having good luck with it, so u ****** read it and find the ones that are running that setup successfully. d98clturbo is one of them, and hes still running it successfully.

H22aAccord

Why redeck it, if its already closed deck?? I cant just order the sleeves that is included in the MID kit?

flip1199

well when i spoke with darton about 1.5 years ago the mid kit for the closed deck h-series is just the sleeves.

here's a pic of darton sleeves in a h-series closed deck block. but this is 88mm bore..

Oh dumbass, I DO read! I have read about every worth-while post that has came through the Prelude forum! How about yourself?

In that post, there was JZ and D98clturbo that claimed to have ran forged pistons in a stock block. JZ ran his for a few thousand miles, then sold the car. Shortly after the kid got his old car, it started burning oil really bad. They pulled the head and the cylinder walls were scarred to hell.

D98clturbo simply made a claim and gave his mileage. That's it. He never gave any more information, he never posted any pics, nothing. He even admitted that although it was still running, he never pulled the head to check for scarring. He may be telling the truth, but I do not believe him, and the information he provided is not enough to believe him over the internet.

So who ELSE has ran these pistons?

H22aAccord

how much did they tell u were the sleeves?
