what would the maximum that i would be able to bore it to? im going for a big all motor displacment motor, with the addition of a vtec head possibly....and higher compression....what would be a size that i can bore to w/o worrying about reliabilty issues....also what pistons, and such would i use for this application? thanx

 

on stock sleeves you can go oversized .25mm afaik.

 

thats it? damn...so on aftermarket sleeves? this is going to be fully built...

 

just looking at dartons website...and they said they can make custom sleeves...i was thinking maybe with a bore of 90mm...that would be sick! can it be done?!

 

found out some more info and found out that i can also bore a f series block and i could use stock sleeves...what would be a good bore size? 89mm? i read that 90mm the walls are too thin and its really pushing it...im looking for reliability...also with the f series would i be able to throw on a h22 hed or is that too much work? i wanna do something crazy yet reliable...please help...sooo many options lol

 

well there is along *** thread about the h22 head on an f22 block. and i doubt you could do mroe than about .25 to .5 mm overbore on an f22 (they astart at 85mm bore). your best bet is do 90mm with some golden eagle or aebs or bensons sleeves if htey support it, im pretty sure darton wont.

 

does the h23 block have that FRM **** that the newer h22's have? i think im going to go with 89mm bore on a h23 block, with high compression pistons, and h22 head...

The f-series blocks are 85mm so there is no way you're gonna be able
to bore them to 89mm. I don't even think you can bore them to 87mm,
someone correct me if I'm wrong on that one.

I wouldn't go any bigger than 89mm if you decide to resleeve it.

ALL H series have FRM sleeves. Just get some good sleeves though at 89mm most anyone can get you sleeve that will support it.

 

true...sounds like a plan....i'll be contacting golden eagle...

 

What I don't understand is why you want to bore your block and put in forged internals that will cost in excess of $1700, but you did not want to swap in some USDM H22 pistons in your H23 for over 11:1 compression. Add some Crower stage 2 H23 cams/springs/retainers and you will get awesome torque and good power and be well under $1700.

Is all of this speculation? Or are you actually going to do something? What are your goals? what do you want to do with your car?

you are correct...that's what FRM was developed for, so that the F-blocks could be bored out further than 85.5mm..and BAM the h-series was born

well that was my 1st plan....but aftermarket support for the h23 is soo poor...the headers suck! only really one type of cams to choose from, intake mani, etc....i don't know what to do anymore....i thought i'd build a 2.4L H23/vtec.....that would be a monster, but like you said, very costly....i might stick to my orgional plan....but i was gonna keep my h23 as my back up motor anyways....my goal is 250 whp....all motor....is dat possible on a h23?!

 

Yes 250hp is possible but most likey you won't want to pony up the dough. Getting a regular DOHC H23 to 250 hp is not going to be streetable unless you think that running nitromethane is an acceptable fuel for the street.

$15000 will get you a 2.3 liter H22 with 290 HP 190 TQ if you go to Endyn. So I would bet that for $10000 you could get 250.

Of course with Nitrous you can get 250 pretty easily. It's kinda NA power.

well yeah im sure i will have a little suntin suntin of bottle time....but i wanna make my h23 something that isnt really seen everyday....andi wanna spank h22's all day :-D i already did once, and the feeling is great...

 

It's not gonna be easy making that kind of power on a n/a h23.

There is a guy on here by the name of 93ludesi I believe.

He invested a lot of money in his all motor h23 and wasn't
very happy about it.

Take a look at this thread

well from what i can see he was running 12.5:1 compression on the street....thats insane...i believe i can make more power on 11:1 compression....with good tuning and deff a shot of NOS
