ok here is the deal i got this h23 swap from a kid who just wanted it out of his garage the only problem was it had a spun rod bearing so i was going to rebuild it and put a new crank and rods in it and a gasket kit and call it a day. but them i came accross a f22a motor as well about a week later then after doing a little research i found out that the f22 crank and rods were the same as the h23's i was thinking sweet but then i was reading that you can just put the h23 head on the f22 bottom end(basicly a f22b-dohc) which seems easier since all i would have to buy is a head gasket. but once again the more i read into it they say the closed deck of the h23 is more stable for boost than the f22 is since its a open deck. so i'm kinda trying to figure out what should i do.

put the h23 head on the f22 block and just call it a day ?

or put the guts from the f22 in the h23 and elegidly have a bigger better motor to start out with ?

Just keep it h23. If you have everything just leave it. In the end it would still be about the same thing. If your not going build it for big boost you should not be worried.

your talking about bigdaddyvtec, he is nothig but a big forced boosting NOG. I'd say go with the H23A1 block and just swap in a set of the type s pistons 10.6:1 and put ARP rod, head,main bolts n and call it a day. I have a H23A1 with 90mm bore but needs one sleeve replaced, and one piston sitting on the side. I retigged the piston, and remachined the valve reliefs but the sleeve is ok for n/a but boost is not friendly. It's going to be a back up motor but going to run the rebuilt piston cylinder a lil rich cause I'm not 100% sure the tig rod was the highest grade. H23A1's are 10.0:1 at least on the one I had before it was sleeved. Stock still friendly for 8psi and yes I know. Did it for 2 years boostin all the way to work"5miles" everyday.

If you have a known good f bottom end... My vote is to toss the h23 head onto the f block... not only will you then have iron sleve liners (should you decide to want or NEED a rebore (now or later ) but the f blocks with headstuds do really respond well to moderate amounts of boost. All you would really need to do to make it pretty bulletproof would be some h23 headstuds (use them for the head swap) and a set of pistons... which as you chose the f , would only require a bore + hone (since you didnt choose the bfrm sleeved H series) , and bearings (oif you dont qwant to be black....)lol.

But the f blocks are pretty strong... I had at3/04e 47 trim 48/509 ar at 15 pounds, and in the accord it was fun fun fun ... 300 whp and 300 tq at 15 psi beaten and driven daily... 25k miles on it (boosted at 144k) b4 i fucked up a ringland.. would have lasted longer but got ia bit greedy with timing... Wanted to turn the boost up to 22ish psi, but the cklutch let go... so we tried to get just a bit more, and the timing pwned the motor...


The H23 head onto the f block is pretty simple trhough.... Just a few things, youll need a water tube from both to make a tube that wikll work and if i remember correctlyt, there is an oil return issue tyhat you need to adress... other than that, the h23 head flows reallly well, and theres always the cool factor of the frankenegro G series...


LMK if i can help you out.

i already stated in my post i'm not building or swaping anythig other then what i stated.


and the reason i would put the f22 rods and crank in the h23 is becouse like i said before there fucked becouse it spun a bearing.




yea i'm only going for about 300 hp can the h23 pistons handle boost as good as the f22 can. so the closed deck of the h23 isnt that big of a deal

bigdaddyvtec

nah the closed deck isnt a big deal at all. The only shitty thing is that the sleeves are FRM and you cant bore them. COnservatively tined, the h23 is a good motor for boost ( im assuming youre nboosting this ******....


Widebody:

Why in the ---- would you put type s pistons in a motor thats going to be tyurboed anyways The compression would be ------- retarded.

bitchasscracker

so would the h23 block be able to handle more power than the f22 ? i know the f22 can handle around 300 ish

bigdaddyvtec

in my opinion, its the pistons that are the weak point of either, the h block is pretty ------- strong due to the closed deck and the frm sleeeves, but as i mentioned above it has its issues to because of it..

id go G series
