H23 Stroker Kits!

I'm rebuilding my H23 and I was thinking about stroking it out.
First im wondering where i could find a good quality kit that comes with everything a master rebuild kit would come with (pistons, pumps, etc.)
Second, im wondering how much HP i might get with boring .030 and some misc. items. CAI. DC header.

I'm also thinking super charger, not a fan of anything that sounds like its farting its way down the street.


If anyone has any info that could be useful during this project, please let me know, I am new to the Honda's, always been in a Z28, Mustang, or Trans Am, so i need all the help i can get.

Re: H23 Stroker Kits!

Thanks Rebel, you are too kind.
Now, can someone please explain sleeving?

I dont understand, why would you bore if you are just going to basically put the original size.

Im so so so confused. :(

oh yeah, It's an H23, not 22 if that makes a difference?

Re: H23 Stroker Kits!

you can't bore the stock H-series block, since they have different FRM (Fiber Reinfornced Material) sleeves, instead of the conventional iron/steel. boring FRM will absolutely destroy the block. instead, the entire cylinder sleeve is replaced with ductile iron sleeves (or other material) which is called "sleeving".
with a sleeved block, you can basically run any forged piston you want (as well as bore it out), as opposed to only one aftermarket piston that you can run in a stock H-series, which is the Mahle Gold's.

Alright, so NO BORING, just resleeving?

I want to avoid VTEC as well, as I hear it gets in the way when you want to change things.

So I want to keep the focus on H23 Non-VTEC.

What would be the best combo to get decent HP and TRQ out of my little block.

And where can I get sleeves and how do you know how to do the right size. my biggest thing is a good combo because these "kits" seem like you have to put your own together. (not good for someone who is just learning)

so any recommendations?

Re: H23 Stroker Kits!

yup no boring with resleeving it first.

it all depends. how much are you looking to spend? cuz i mean like those brian crower stroker kits are like 3K.

the h22 and h23 block are almost identical, the differences are mostly all in the head(and supporting parts as well of course). so those kits would work just fine for your h23. as far as where to get sleeves, just have a shop do it. its not something you can really do your self, with out having all the machine work tooling.

Re: H23 Stroker Kits!

ya i'm not sure on the size either... i think 50mm is the stock size, and the 55mm is the larger/stronger sizing. in which case you'd need to have your block line bored for that crank to work. but it would be stronger all around.
although i could be completely wrong with that..

edit nvm, The official H/F piston/rod/crank/block specs and CR thread - Honda-Tech you have a H23a1 right? ok so then you'll want the 50mm verison.

and as far as a supercharger, go look on jackson racing's website. heres the link: www.jacksonracing.com

after that, i'd get maybe the brian crower stage 2 forced induction cams, new valves/springs/retainers. and then a port and polish.

add a light weight flywheel, like a fiadenza 8lb and a stage 2 clutch and you should be set.

oh and HAVE IT DYNO TUNED, By a experienced tuner!!

ya no problem man. another i would do, actually i end up doin it alot. is find a local shop you like, and get talkin to the guys there as well. they should be able to help you find parts the exact parts your gonna need depending on what your budget is and such.
i always like goin to the smaller shops(not like out of a guys garage small, just the ones that arent like nationally known, makes sense) because normaly they charge less and tend to be more personal towards the work on your car.

i know for up in washington(where i am) i goto fluid motorsports for pretty much any work i need done. plus i know the tuner up there pretty well. so works out.


*rep is always nice* :)

so any recommendations?

Why do you want to avoid VTEC now? VTEC is an excellent option to make more power in every part of the power band. In all my years of working with Hondas, Ive heard this misconception that VTEC gets in the way or becomes useless when modifying a stock motor and never once has this ever been true.

Even VTEC Killer cams are designed to 'eliminate' VTEC and their sales are down because people have realized how dumb of an idea this is. The only benefit of those cams was easier tuning, even with gobs of power loss in the low to mid range... Honestly, who wants to give up a good idle, low end torque, and the high end power VTEC will make?




Also.. Welcome to the H/F series world. Our world is much different than that of domestics and even the civic B series guys. Our motors dont have the aftermarket support or options that many of the more popular platforms do. Buying a stroker kit isnt going to be cheap or easy. Actually, I wouldnt call it a cost effective or even time effective investment. If we want to stroke our motors, we look to using a F23a1 crankshaft and rods. Those come from 98-01 or so accords and are a dime a dozen.

F23
Cost: Under $500 anywhere
Stoke:99mm


Crower stroker:
Cost: $3k
Stroke: 100mm


Ill say the crower kit does include rods, pistons, and a steel crankshaft... But, Ill say you could spend the extra money you save and buy the supercharger, ECU, injectors, and a good header on that budget...



I guess I'll also add a disclaimer here. I do know what Im talking about much more than many of the other members. Ive built more than 35 successful H series motors. Ive been playing with these motors for over 9 years now and would guess Im one of the most knowledgeable members on this site or any. Ive built budget builds NA for less than $2k that put down more power than the supercharged guys are FI and I'm one of the few guys to have taken a Honda Prelude down a drag strip in less than 11 seconds (and a even smaller group to see less than 10 seconds 1/4 mile.)

Re: H23 Stroker Kits!

talk to a local shop who has experience with this engine and you will get answers such as:

"why buy a stroker kit when the h23 already has a good stroke?"

There are no superchargers for the h23. You are **** out of luck on that thought.
