Cars mostly planned out except for something but one im still considering is H22 stock head or fully built H23 head. I have a full h23 motor and i am converting to 5 speed with a h22 tranny. in that im still looking into getting a h23 or a f22 5 spd tranny since they have longer gearing. Since i took out the f23 on the f22 tranny i gotta make these decisions since it was an auto car. Also can someone explain water to meth injection?

So you want to put the H23 or H22 head on an H22 or F22a?

H23. He's debating the H22 head or H23 head.
What are your plans... turbo or NA?
Water/Meth injection is used to combat detonation, primarily in turbo motors. It's one way to tune for more power without running extremely high octane fuel.

Well, with that said, if you wanna go turbo, then go with h23 head and block, since you already have a fully build head turbo would be the way to go, and you can do N/A to but its up to you, difference is that you wont have vtec. (if you have the non-vtec version)
And H22, you can turbo it to, since h23 block has like about 9.8:1 compression and 160Hp stock (if healthy) then go turbo to, only difference is that you will have Vtec with the h22 head (with proper wiring and ecu) or you can go N/A, its up to you bro your choice, I gave you my input

search on the water meth (there was a thread recently opened)Originally posted by Youngill726 View Post
now let me get this straight:
you have
a full h23 motor ?
youre undecided if to swap heads, or to build yours right?
also you have a h22 trans and want longer gears right?
h22 head you'll have vtec, but to swap heads, you'll need to weld water pipe, swap water pump gear and your compression will go down from 9.81 to 9.31
h23 head you wont have to modify nothing, you'll have a built head ready for abuse
both combos are good for turbo, not that efficient as an allmotor setup
keep h22 trans, 80@4k rpm deal with it

Its for boost. the block is fully built(h23A3 block). got rid of ebay turbo and going with a bigger sized one.Comment

Fully build block? What compression are you at?Originally posted by Youngill726 View Post

it just i had the decision to have vtec from h22 or fully built head. At the same time if i did the h22 head and did turbo cams wouldnt vtec be eliminated? i have bought everything else i think i would need except lsd and water to meth injectionComment

i got mahle h22 9:0:1 -7cc dish pistons on bisimoto f22 rods. the piston tops come out i think 18 hundreths but i got a thicker hg for thatComment

I'd stick with the H23 head for reliability, then.
And no, you wouldn't lose VTEC with turbo cams unless you specifically got them that way.
The H22 head isn't all that spectacular in terms of flow. The VTEC valvetrain is bulky, and that results in less-than-optimal port design.
If you're going turbo, the H23 head will be just fine. Since you seem to have put a good deal of money into the build, you should be good. The H23 head will also decrease the chance of something failing due to something minor you overlooked in the head swap.

stock vs stock, h22 head will outperform it

its tempting to be honest. even when i had my f23 in i didnt have vtec but now that its a option i wanna take it but then i dont. U see what im saying. if i knew i was gonna build the h23 i would i have gotten a h22 and built it . but the 1st time the car ran turbo it blew up due to no boost gauge. so i went in and ordered everything new. I was told that later on down the line i could go h22 head and make more power.Comment

The H22 head isn't really going to make significantly more power with turbo than the H23 head, and you'll run into potential problems with the custom headswap.
If you want to satisfy your own curiosity, do some research on the flow properties of both heads. Then you'll know what's best for your plans. Most people on here (including myself) don't have that hard evidence to present to you, and going on "what you've heard" is a very bad way to build a motor!

ur right thats how i got myself into buying new motor and complete kit. i listened to someone that told me they knew what they were doing and the car blew up at my expense at the hands of him. now i have spare part from three motor lying around. but im in better hands now pro handsComment

Yeah, ALWAYS know what you're doing.
Honestly, you should always know what the pros are doing to your car as well. If you don't know what they should be doing, you won't know if they're doing it wrong! I had my H22 installed for me by a shop back in 2003... and they halfassed EVERY step. I'm still fixing crap they did wrong...
When it comes to modifying your car, take the time to learn everything before you do it... or you're going to have to learn it all when you have to re-do it!
At least you picked back up and gave it another shot. So many blow up and never rebuild. Even done right, things can go wrong. It's just part of the game we play!
