Like the type-r of the h series
500whp of spinnin fury!!!
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
i just noticed this is your first post, welcome
I will buy you're fuked up motor!

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
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.
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
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!

if you want to rev to 8K, trade it with me. i got a JDM H22A for ya!
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
LMK if you need sensors or plugs...i have a whole h23vtec engine harness in my garage..
did you switch everything out to OBD1?

nope they used everything off my old h22a motor to put on the old one so it will still be obd2
and say if a prelude with a h22a4 motor an mine with the blue top raced which one would win?
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

there is a h22a7 that came in the accord type-R in europe that puts out more power than the h23a vtecLike the type-r of the h series
About to approach beast mode
how do u think it would do against a stock mustang gt cuz they blew my h22 away no prob
ok wat about a mustang gt an the blue top cuz they smoked my h22a all day long
i dunno...thats just b/c the lude is heavy
