[jbdover08]

ok heres my story i have a 98 prelude sh with the h22a4 motor well i recently the pulley broke and warped and f'ed up my key way so i figured should i fix the crank with a crank kit or buy a new motor and i did my research on these motors and the seem to be pretty good and more hp an torque so i bought it a h23 vtec "Blue Top motor" any one kno anything about this particular motor

:lmfao::lmfao::lmfao::lmfao:

but for real, i thought that it was just a 2.3 version of the h22, but there is a book at autozone that you can go in and read, it's called "Honda Swaps" and according to them it's a totally different motor, and that some of the parts from the h22 do not fit it, how much truth there is to that, i dont know, believe it cause they seem pretty credible, last time i checked they were going for a bit less than the h22, jhotimports when they were in Augusta had a couple of them, i love that blue valve cover though.

if i were you i would just go with the jdm h22 and the lsd tranny

google ftw!

What you need to know? I had one in my hatch and its a beast.

Same head and block castings as the h22 were used....it has a longer stroke and flat top pistons(as opposed to the "dome" of the h22a) thats where it gets that extra .1 of a liter. Its a great motor, just don't rev the piss outta it b/c its powerband and bottom end were designed for the auto AWD tranny. If you decide you want 8k rpms all day, then stick with the h22a:goodjob:

Pretty much all the specs have been stated and yes, google is your bestest friend!!!

They are a little more expensive due to the fact that there aren't near as many of these as there is the h22a.

I picked mine up for 1400 cash(normally 15-1600) with a business tax ID from Matt Harrel at Japanese Engine Importers in Doraville. Great place to get a motor from!

[NoWAyItZTOMmY]

if you want to rev to 8K, trade it with me. i got a JDM H22A for ya!

[jbdover08]

na the swap is almost complete im waiting on a pulley from honda they had to order then everything is goin in... everything is new new seals all around clutch kit. im selling the old motor for 500 it will crank and run no knocking or anything just the end of the crank is sheered bad.. all they had to swap was the oil pump the housing around that sumthin about the oil pan they had to swap im not sure wat it was intake plenum headers an thats it it dont have an egr valve and the oil pump housing an pump was swapped to add the crank angle sensor but i should have it monday night so i will let everyone kno how it runs? if it has any more than the h22a it will be a beast in the prelude

[D3UC3S]

LMK if you need sensors or plugs...i have a whole h23vtec engine harness in my garage..

did you switch everything out to OBD1?

[jbdover08]

nope they used everything off my old h22a motor to put on the old one so it will still be obd2

[jbdover08]

and say if a prelude with a h22a4 motor an mine with the blue top raced which one would win?

[D3UC3S]

blue top...torque is the winner.

if you need any sensors or plugs LMK...there is a pic of the harness in the link in my sig:D

[K24cb7coupe]

Like the type-r of the h series :ninja:

there is a h22a7 that came in the accord type-R in europe that puts out more power than the h23a vtec

[jbdover08]

how do u think it would do against a stock mustang gt cuz they blew my h22 away no prob

[jbdover08]

ok wat about a mustang gt an the blue top cuz they smoked my h22a all day long

[D3UC3S]

i dunno...thats just b/c the lude is heavy

in the hatch i ate up GT's all day long...

[jbdover08]

o well i will be happy if i tell any diff at all lol i might put some cams an i got a port an polished head im building on to

[D3UC3S]

It is a whole diff powerband...you will def. notice

[jbdover08]

what gear is gonna be my strongest an wats the safe rpm range ?

[D3UC3S]

get it tuned before you do anything...

second gear is a beast and 4th on the hwy dessimates:D

dont rev past 7500....

[jbdover08]

well itll have to be summer before i get it tuned cuz money an work is slow but im not gonna be racing or reving it high anyways because i need a reliable car and dont have the money to pay if something breaks because of racing

[D3UC3S]

yeah be easy with it till the tune...shift a 3k all day till then

[jbdover08]

lol cant i just see what shes got once or twice lol

[marcos713]

hmm interesting, ive heard of the h23 vtec but never actualy seen 1 in person. or maybe i have just never noticed lol.
GL with the motor man

[D3UC3S]

I posted pics of mine in the hatch...someone on the boards has it now

[BB6Luder]
