What about the h23?

[lil_dcb7]

What do you guys think of the H23a1? Yes, its the USDM one. Would it be worth the swap?

There's a wrecked 4th gen prelude at work, and the only thing that was ruined in the engine bay, was the air intake box. Its really no big deal. It was an impound and when the lein goes through in ten more days, it becomes the bosses. When that happens, I was thinking of getting it from the boss
But im not if the swap aint worth it. stay with the f22 or go h23 (both auto...)?

[IBCNYA]

yeah man...depends on price too though...i would scoop it up...

[Kanibus]

the h23 (f22b dohc) is pretty nice, an improvement over the f22 for sure. If you can do it for a decient price, do it.

[d112crzy]

i would do it, for a decent price tho. h23 is a strong motor, it pulls pretty hard. i would build it for boost, get sleeves, rods, pistons, the works mang. then boost the motha out.

[lil_dcb7]

are there any drawbacks of -STILL- not having vtec? I really want to boost. Which is a better boost build? h22 or h23?

[FDAccord]

who said there were drawbacks for not having VTEC? If anything you can search here, the H22 head can go onto the H23 if you really want VTEC. Me personally I would rather spend the money on building the motor for boost than getting VTEC. But look for the accord on here with the headswap and ask him how it is.

[Travolous]

better to boost the h23.......i wouldnt boost the h22

[lil_dcb7]

Yeah, im not too sure im going to do a headswap. Like i said, I REALLY want to boost. But i have NO experience what so ever. I read up on homemadeboost.com and i was lost. Something about sleeves and h22 pistons and new connecting arms? Meh? Do they sell turbo kits for the h23?

The H23A1 is a very good engine. If you get it for a good price it will be a worthwhile swap. Will give you more torque and power, deffinately a noticable upgrade.

H23A1's take more to boost in stock form then an H22A would because of it's lower compression. The lower compression makes it work more effciently and safely under boost. A more forgiving setup.

[H23Accord]

The biggest difference between the H23 and H22 would be power. Basically imagine the power being on opposite ends of the spectrum and you basically have what each engine accels in. Initial torque is lower in the power band in the H23 thus giving you power in the low end of the spectrum while the H22 will give you power in the high end of the spectrum mainly in VTEC land. You will definately notice a difference in power going from the F22 to the H23 especially in the low end.
BustedLX basically said what i would have said about boosting. It is why so many go N/A on the H22 and boost the H23.

if not just get the head..... and sell me the timing gear....

[lil_dcb7]

if not just get the head..... and sell me the timing gear....

lol, eh no


so, i noticed you guys said about lower compression. I want to be able to get, a very nice amount of boost. I know the most common is 8 or 10 psi. What can I do to get more. Like i said, I am a NEWB at boosting and ish like that. But i have been told, boosting is the way to go... how do i lower compression? How much work am I looking at? I'm aiming for around 260+ hp...

Ok I hve the H23 in my car from the f22a4 with the A6 manifold. The H23 pulls lot harder then the f22a. I remember i could spin/chirp 2nd gear with my F22 but now with the H23 it just wants to go. same tranny i had with both motors. my friend drove my car since i did the motor swap and he notice a differnece in power instantly. it pulls harder adn torque its right their not like it was with the F22a. The motor was turbo already and it pulled hard as hel for only 4psi of boost. If i could recall it pull a est 175hp on the dyno un-tuned, than was auto then (MOTOR WAS IN A PRELUDE) just slapped on a drag turbo kit and than was all. I do have a f22b at my house. selling the block if anybody is interested if you want non-vtec and torque and turbo go with the H23

[h22sparkle]

I say build both before you boost. Either one can fail and be unforgiving in reality spec. And not to mention boost is unforgiving if its gonna go bro its gonna go.

[clarksterdotcom]

so danny did you take in what i told on AIM.. its more than just vtec and CR sleeves etc. just buy the motor already...sell the Z and go all out on the accord. and get down to the DMV boy...

hmm.. well you should also talk to ssdaccord hes from daygo and im sure hed like to help out a fellow cb7tuner with a swap
