H23A1 - USDM DOHC nonVTEC
H23A - JDM DOHC VTEC (rare)

 

thanks a bunch man
well you tell me more about the h series motors though. Like what year car had what motor in it and how much hp they had . i wunna know about the 92 all the way up to 01 preludes.thanks lucyh23

 

Not true because I have a JDM h23a non-vtec, but there is a h23a vtec model (blue top).

 

The H23A1 was available in the 92-96 USDM Prelude SI. 160hp and 156tq. The JDM H23A VTEC was available in the Accord SiR wagon. 200hp and some high amount of tq (180 or something)

I don't understand it either, but I bought it as a short block and couldn't figure out why it wasn't the vtec model.

 

Also I found others with the same, but could someone please explain where the h23a non-vtec comes from?

 

must be the h23a block with the h23a1 head on it.... why someone would do that i dont know...

 

was this motor oem? what contry is this? and where did you get the car? motor history tell us more.. has their been a swap done?

 

myself as well as others have bought these engines jdm from supliers such as hmotors and sunrise which they get in every once in a while. And yes these are swaps, but is there anyone who has info on these engines?

 

if you were able to do a compression test that might tell us soemthing about the pistons, if i could find some stock h23a1 compression numbers to compare them to..

i would also be very interested in the bottom end, if you pulled the oil pan off and were able to somehow measure the mains if you pulled a cap.

 

Alright check it out I found that there is a h23a non-vtec when talking with someone who really know his stuff and found a website:

Turns out it comes in the 96+ preludes in Japan, but the question is whether the block is a closed or open deck compared to the h23a1.

well it probably closed deck, they didn't go open deck until 97. it would be interesting to know all the specs on your motor..
