Has any of you guys personally done it? And whats needed to make it work on a closed deck h22. It raises your comp to 12:1 right?

 

that woluld be way cool!

 

i was going to but the cost is too high on those pistons. they are like 140 bux each.

type S pistons and mill the head?

I wanna keep the sleeves OEM because of reliability issues, thats why i want to run s2k pistons. I just wanted to know if its been done before. And if i could hear your accounts on going this route.

 

no, from what ive read because of the wrist pin location the s2k, the piston will sit lower in the cylinder producing lower compression.

just go with the type s, small overbore, thin headgasket, and if you want more mill the head.

 

Yea true..

 

i had read that some peopel in japan had done it and were seeing high 12 to low 13 to 1 compression....but i cant find teh page agaian to show anyone

 

But no one on this board can say anything from personal experience?

 

nope.. like i said, they cost way too much, i can get coated strutted wiesco's in any compression i want that will work in the stock sleeve for less than that

the idea has been kicked around, but like stated above the wrist pins location makes it less feasible than using type s pistons and milling the head or using a thinner headgasket.

Yea, i know its been thrown around alot but i was wondering if any of YOU guys have done it personally so i can see the end results. And about running weiscos on the stock sleeves, i wouldnt try that either. Too damn risky.

 

I guess that guy on the other thread was the only one seriously considering it but it looks like it never fell through. Why don't you try it and let us know how it goes?

 

if wiseco made an off the shelf psiton in a bore i could use i would be running them in my next engine. but since they only make 87, 88 and 89 mm bores i am SOL with stock sleeves.

 

wiseco does make hi comp pistons that suit a standard h22a bore. My friend just bought a set and the compression is bumped up to 12.5 and even more with his metal head gasket

 

last i heard, S2k had forged pistons which doesnt do a body good when coupled w/ h22 FRM sleeves.

 

That would have to mean that the S2000 used a different kind of FRM then?

SO yeah, the reason none of us have any experience in doing it is because there is no point, there are cheaper/easier/more readily avaible alternatives do doing what the s2k pistons accomplish......... thats why no one is doing it... and who told you stock sleeves are reliable? and yes....... 87mm is stock bore

 

Well i just took it upon myself to think this since most of the b series boys tell me that going oem sleeved with civic R pistons is more reliable then resleeved block running after market pistons. Or so says Rocket.

 

comparing a stock B series sleeve to a stock H series sleeve is like comparing my interior to a caddy. 2 different worlds......

 

the s2000 uses the same frm that the h series does,. it has a 87 bore, and what honda did was find a way to make forged pistons work with frm. neway here some math

compression height (distance from pin to top of piston)
H22 piston is 1.220
H23 piston is 1.204
S2000 piston 1.178
using c-speedracing.com with a piston dome cc of 11.07cc


with the s2k piston it would sit .042 mm lower than the stock h22 piston in the bore. and would yeild a 10.52:1 compression ratio

with the s2k piston it would sit .026 mm lower than the stock h23 pistonin the hole. and would yeild a 12.23:1 compression ratio

if you guys have any question feel free to ask

B series don't have this problem.

 

i am actually more excited about the 2004 s2k pistons they are even lower compresion., and may be worth while looking at for boost option, stock forged pistons with frm,
