My engine has 109,000 miles on it. Im really looking at getting a new h23 head for it...P&P...Racing Valve grind...ported intake manifold...ported throttle body and camshafts. This head is a Bullfrog head..which can add up to 60 hp at the wheels. My questions are...what compression forged pistons should I get after the head install...as I will probably end up turboing my H23. And sleeves...I'm not familiar with what piston compressions mean and sleeving means...thank you for your help....

 

have you phathomed the thought about getting an H22 vtec head for your H23 block? it bolts up directly to the H23 block no problem.

 

I have thought of that..but you get problems with that conversion. Plus the h22 head already has miles on it and isn't P&P....and won't at up to 60 hp to my wheels. I'm for the power and speed not necessarily the VTEC. Or are you telling me instead of a new h23 head I should get an H22 head?...what is the difference besides the VTEC?..

 

ha! I can't believe what you just typed. Do you even know how and what VTEC is?

VTEC isn't some toy upgrade that makes a louder noise once crossover is reached, ya know. It blows away non-vtec engines by far. That's what VTEC is..Power & Speed..lol.

 

I know what VTEC is...Valve Timing and Electronic Control....Vary aware of what it is. But, I didn't know whether you were talking about a used h22 head or a new one. I was refering to the used one....

 

I was referring to any legit H22 head (used moreover) you can get your grubby lil' paws on. Did you know there's an H23 VTEC engine in Japan? it's found in the Accord SiR-T wagon. It's an H23 block w/ H22 head.

 

I did not know there was an h23 Vtec in Japan. Why would I prefer a used Vtec head rather than a new port and polished one?...because it's already broken in. A new one would be like having a new engine...a used one has miles on it already.

 

...because an H22 VTEC head in its unported/stock form will more than likely blow away a ported NON-vtec H23 head. And also, don't forget that the H22 engine makes 190hp; H23 makes 160hp.

I'm just trying to help you out buddy, not shoot you down..

 

You wouldnt. You already have your mind made. You've got a decent build plan. With a vtec head you'll need a new ecu too. You may consider an h22 tranny though.

 

So Katman your telling me to add an H22 head to my engine rather than an H23...and a used h22 head rather than a new P&P head. I know your not shooting me down Kat. And the other guy....your telling me to stick with my plan...or go with the H22 head and get a ECU and H22 Transmission to boot.....thanks for your 411 guys.

 

First off Katman what makes you think that an h22 head is better than a P&P H23 head..Because its Vtec..hahahahah...if you think about it if he keeps his H23 head and puts cams in it the its better than the H22 head..you know why because he doesnt have to wait for Vtec..his power will come in at around 3000rpm..Matters on what cams you go with..I work for a guy that does P&P on heads and he make LS heads flow just as good as a P&P b16a head..And if you think about it if he gets the h22a head he might be slower because the h23 pistons are not as good as the h22a are...and if you are think the h22a is better in a way your right but not because if he gets a h22a head he might gain hp but not that much and think about it he would have to get the h22a P&P and get cams and spend more money and a ECU..and the h22a and the h23 trans have the same gearing but it matters on what yr. i think..because my friend has a h22a motor with a H23 trans and his rpm are the same as mine and i have a gsr trans..his 4th and 5 th are..so i would just keep the h23 head and get some bad *** cams and double valve springs and if you want get over size valves on the intake side and cam gears and go kick some VTEC ***...

 

oh sorry get some 11.0 compression pistons or even go with 11.5..and get some new injectors after that get some h22a injector they are like 290cc and you have 240cc now..kinda because i have 12.5 compression on my motor and i am running 240cc injector.but just get them to be on the safe side..and you dont really need to resleeve unless you do turbo or the block is fucked or you just want it for safty on the motor...

 

Sooo...allmotorb18 your telling me to stick with my factory H23 with 109,000 miles on it and just get new cams, valve springs, and pistons? Or are you telling me to get the P&P head rather than the H22 P&P head that Katman was suggesting and do all of the above to the P&P H23 head? I'm a little confused as to what you are suggesting but I think you are agreeing with me. What are cams and valve springs? Cam Gears?...thanks for the 411

 

Im sorry to say if you dont know what cams,valve springs and gears are then you dont need to be building a motor..but cams are what makes the valves open up and the valve springs are what closes the valves.I can explain it better by saying it then writing it and the timing belt runs on the cam gears to turn the cams..

 

I got ya...thanks

 

another thing to keep in mind if you plan on keeping your h-23 head...the combustion chamber is smaller on the h-23 than on the h-22. if you already have the 23 head...get it ported, polished, cams springs...etc... if you want to turbo...i would suggest the 22 head. larger combustion chamber...lowers compression.
h-22=53.8cc's h-23= 50 cc's
i am building a 23 with a 22 head , turbo, nitrous for my hatch...mang its expensive....but if you have more ?'s im me and i can help you out more.

yes, i'm suggesting to get an H22 head, whether it be used or brand spanking new (its up to you), and then apply it to your H23 block. Of course you'll need the H22 P13 ECU also, and an H22 tranny since the gearing goes hand-in-hand with the VTEC powerband. You can also add an H22 tranny if you plan to stay 100% H23...i know it will help acceleration since the gearing is -better- than an H23's gear ratio.

 

First off Katman what makes you think that an h22 head is better than a P&P H23 head..Because its Vtec..hahahahah...

***
actually yes I do. It's no different than comparing a B-series VTEC head to an LS head. And a majority of built DOHC VTEC engines ****-down any built LS engine. It's a known fact, sir.
*****

if you think about it if he keeps his H23 head and puts cams in it the its better than the H22 head..you know why because he doesnt have to wait for Vtec..his power will come in at around 3000rpm..Matters on what cams you go with..

****
DUH..
So, tell me this. How's it any different if he went with a set of Euro-R or Type-S camshafts if he did indeed, wound up going with an H22 head? Where would that put him now? and then, just for shitz & giggles, lets say this H22 head was p&p too! Then what? Ya know, the powerband before VTEC isn't as shitty as you're perceiving it to be either. I get the impression you don't want VTEC in your life eh?
*****

I work for a guy that does P&P on heads and he make LS heads flow just as good as a P&P b16a head..And if you think about it if he gets the h22a head he might be slower because the h23 pistons are not as good as the h22a are...


****
ok, then he needs get better pistons .. woot.
****

and if you are think the h22a is better in a way your right but not because if he gets a h22a head he might gain hp but not that much and think about it he would have to get the h22a P&P and get cams and spend more money and a ECU..and the h22a and the h23 trans have the same gearing but it matters on what yr. i think..because my friend has a h22a motor with a H23 trans and his rpm are the same as mine and i have a gsr trans..his 4th and 5 th are..so i would just keep the h23 head and get some bad *** cams and double valve springs and if you want get over size valves on the intake side and cam gears and go kick some VTEC ***...

***
actually I'm gonna stop replying to you because I'm tired of reading the run-on sentences.
