Who makes 10.5:1 or 11.0:1 CR pistons for the H23A1?

I was looking on Crower's site and I only found 9.0:1 and 10.0:1. Stock is about 9.8:1 (right? correct me) so I'm not sure if a 0.02:1 CR gain would be significant.

I'm planning to get either Stage 1 or 2 N/A cams also or maybe custom. And I want to keep my car streetable.

Thanks.

 

You found pistons on crowers site?

 

Goto http://www.raceeng.com They sell every internal motor piece known to man (almost)

 

11.0:1 is very streetable with 91 oct gas.

yup heres a link: http://www.crower.com/cat/impo...shtml
just scroll all the way to the bottom. at the top of that page it says JE pistons but i was thinking its just a branch of crower or something. same with CP and SRP.

thanks for that link too. i'll check that place out.

wouldn't 11.0:1 CR pistons have clearance issues with the stage 2 cams? or is that just if you use 11.0:1 CR H22 pistons?

i just went there and they only had one piston for the h23a1 and it was a 9.0:1 CR piston.

anyone know if Crower makes custom pistons?

i'm looking for forged ones too just because it's stronger.

if i cant find any forged ones i might just have to use h22 pistons. what would the CR be with 10.0:1 CR H22 pistons or 11.0:1 CR H22 pistons?

thanks again guys.

 

I don't get it...

you're going to sleeve your block and buy forged pistons..to go NA in an H23a? I that's a lot of dough to spend..

I'd rather buy JDM H22a 10.6:1 and not sleeve the block, in H23a that will give somewhere higher than 11+, type-s is too high I've seen some melted type-s in H23a scenarios.

The compression height is slightly higher with the H22a though, I think Rick did measurements, but I beleive it doesn't cause clearance issues, someone else should confirm.

Just not sure why you are entertaining sleeving for NA when there are cheap options out there. Of course, I'm not sure why you;re going NA on the H23 to start with...but that's another discussion.

 

im goin with the jdm non type s pistons...like this i dont have to sleeve and i get great compression numbers...

 

I would go with jdm H22 pistons as well. Sleeving an H23 block to go NA doesnt seem worth it...

i'm just gathering info and finding parts right now. i don't have a set plan yet. but i know what you mean.

anyway, what will the usdm and the jdm pistons come out at in the h23? i read somewhere when i searched that one of them comes out at 11.7:1 and that the type-s pistons would be too high.

 

usdm h22 is like 11.2:1
jdm h22 is like 11.7:1
type s is like 12.5:1

something like that...im sure im a little off...some1 post the more accurate compression numbers if you know em please.

 

hhhmmmm so the jdm h22 pistons will fit in a h23a1 score im doing wat ralpheyizzle and many other seem to be doing in making a all motor h23 my goal is to just hit 200whp and ill be happy so my compression would be about 11.5 :1 with jdm pistons huh sounds good

 

i thought i was the only h23 shooting for 200whp...guess i was wrong.

 

haha yes i am also trying to get 200whp i will get eventually just trying to find some info to make my goal a reality

 

what do these pistons really do, im a noob and i kind of want to learn on all those compression ratios n ****.

 

and can u get ss valves for h23

there's a rise in the number of people trying to get 200whp in an all motor non-vtec. i think PirateMcFred is the closest to that. he has a hybrid with parts from many different engines in it. there's a thread in the FAQs with info about his hybrid.

the piston is the part that compresses the gas and air mixture.

ss as in stainless steel right? i'm not sure but i think you can. someone correct me.

 

Jesus you guys..

Your 60 whp short of 200whp.. YOUR NOT GOING TO GET THERE with the H23 without HUGE money..

With that money - you could boost it and make 300 or buy a JDM Type-S with bolt ons for WAYYY less.

 

no ill get there with a couple grand at most and a good tune and the right parts i can get there i got it all mapped out ill be sure to post everything i do with a dyno most likely

and be like every1 else....BORING!!!!! i love the h22....but my car came with a h23 and i dont have money for a swap...so little by little my car will make it to 200whp...

ps...i havent lost to 1 h22 yet

 

and i got my friends h22 in his 5th gen auto prelude

 

oooh wow you took your awesome h23 and beat the piggiest 4 cylinder car with an h22 you could find....to boot its auto

you guys really are wasting a lot of money, you are not gonna get 200whp

pirate has 180 whp/tq with 11.x compression and stage 2 cams....lets see you get 20 more whp without wasting a rediculous amount of money...

you go spend all your money on your quest for allmotor 200 whp out of an h23...

seriously.....to get 200 out of h23:
jdm pistons - $200
good header(not dc ****) - $650
catback - $400
custom IM - $650
bigger TB - $350
intake - $150
stage 3 cams - $700
valvetrain - $300
head porting - $800
hondata - $500 (do they even do non-vtec???)

and you might even fall short then, thats $4500 spent, and not even to mention that your gearing still sucks *** and you have no limited slip...and most of you idiots wouldnt have a clue on how to put the pistons and cams/vt in so you would have to pay for install on that too.....

h22 w/m2b4 lsd swap from hmotors - $2250
smsp header - $1200
catback - $400
intake - $150
hondata- $500

200whp for $4500

WITH AN LSD and WAY better gearing for all motor....

consider your options before you waste your money on random crap...not to mention lower compression, better gas mileage and driveability, and no hassle of tearing the block open.....

and then when you are done, you can save up for some cams and the jg IM and a TB instead of neons and make real good hp numbers....

 

yes^^

search!!!!!!!!!!!!!!!!!!!!!!!
