H23A Vtec Straight Swap?
Minus the mounts, does the H23A vtec fit into the integra? I've trying to figure out why the H22 is so much more expensive than the H23A when the HP is the same.

Re: H23A Vtec Straight Swap?
h22 is easier to get parts for, more well known/well documented
there are small differences..I think the h23 oil pan is deeper, which would suck for swapping into a teg, and the pistons and rods are different than h22 from what I have read.
Power wise they are similar, but you could run into trouble trying to get some replacement parts I suppose

Re: H23A Vtec Straight Swap?
The H23 is a great motor to swap. It's a beast for the $$. The differences are subtle, which is why people go with these once their H22 bites the dust. I/H/E/Tune and these will make pretty good power. The advice above you doesn't make any sense.

Re: H23A Vtec Straight Swap?
Also remember it's not just like swapping in a b-motor, it's a little more involved. I would also suggest getting an H2B kit so you can keep your b-series transmission. An H23 with an a b16 trans or ITR trans would be a lot of fun in an Integra.

Re: H23A Vtec Straight Swap?
Either way, I'm not slamming, and I'll put a skid plate if need be. The H23A vtec blue top seems WAY worth the price. I'll also be doing the H2B swap.
I saw your second post after posting this one...but yea I don't have anything except for a shell, so my options are wide open. Probably going with an LS trans, don't need those shorter ratios.

Re: H23A Vtec Straight Swap?
Yuck, LS trans? At least get a GSR trans. B16 would be the cheapest with the best gearing.
There's things you need to do to the H23 to work with a USDM car, like swap the oil pump or something like that. Just look up H23 swaps (for preludes) and there's a whole writeup.
Here's a build, I didn't go through it. Should help a lot with any of your questions. Google is the ****.

I'm not building this for race, it will be street driven from time to time, but not a daily.
I'll check out that build, I'm very familiar with swaps, just not with the H or with the DC chassis.
EDIT: I've seen that post, dude got a little crazy with the grinder, I'll be going for an H2B kit.

Re: H23A Vtec Straight Swap?
If price is the determining factor then the h23 is prob the way to go.
Reason I bought up the oil pan is bc these h22 swaps already sit low, and im sure his car is lowered also..so with a deeper oil pan it will be closer to the pavement, more chance of hitting/ scraping it.

Re: H23A Vtec Straight Swap?
my advice doesn't make sense? the oil pan/oil pump/bottom end its much different than h22 and most ppl seem to be very unfamiliar with them, making the h22 an easier swap.

H23A DOHC VTEC
In 1998, Honda of Japan produced a rare DOHC VTEC version of the H23A engine for use in Japan only. It has been factory modified with an internal oil passage in the H23A block to operate the VTEC solenoid in the H22A head. Having the same horsepower rating as the H22A engine but it has a lower redline because it has a longer stroke than H22A. H23A DOHC VTEC has 87mm x 95mm (bore and stroke)and the H22A DOHC VTEC has 87mm x 90.7mm (bore and stroke). The H23A DOHC VTEC Engine is largest displacement in the H Series engines with a compression ratio of 10.6:1.
Found in the Japanese 1998-2002 Accord Wagon SiR (CH9). It produces 200 PS (147 kW; 197 hp) @ 6,800 rpm & 163 lb·ft (221 N·m) @ 5,300 rpm and comes with a "blue top".
Found in the Japanese 1998-2002 Accord Wagon AWD (CL2). It produces 190 PS (140 kW; 187 hp) @ 6,800 rpm & 163 lb·ft (221 N·m) @ 5,300 rpm and comes with a "blue top".

Right from the sticky on HT
Rod Length
H22A4 = 5.633
H22A = 5.633
H23A = 5.572
H23A1 = 5.572
There is a lot of info floating around, how is anyone supposed to know what is true anymore with out actually doing it first hand?

Re: H23A Vtec Straight Swap?
Welp, putting in a B20 or straight LS motor. Not going to screw around with H2B or anything fancy...I'm going for a good running, reliable and excellent looking build.
