H23a1 VS. H23a3

Hello all, quick question...

What is the difference between a h23a1 and a h23a3? My first guess would be that the h23a1 was in the 92-94 ludes and the h23a3 was in the 95-96 ludes or something similar to that. Is there any other minor differences or anything like that? I ask this becuase my engine came last friday and of course the first thing i looked at was the engine code and noticed that my original engine is a h23a1 and the one i got is a h23a3.

thanks

btw: i have a 94

Honestly, I've never heard of an H23a3...maybe it's the obdII version.

If thats true, that u found it was in the euro Accord...then that might be that mythical H23 that had vtec....


spec something like 220hp and 160 something torque...

if Its true, I would love to have that engine!! In Sport Compact CAr last month this store ardperformance advertised it had an H23 vtec I just wonder if its all true

nope, the H23A DOHC VTEC came in one of the Accord Wagons in Japan. HP was about 200, not 220.

It came in 2000+ Accord Sir-T Waggons. Actually, it has slightly LESS HP than the JDM H22. Crazy, huh? (its rated at 220 or PS, which is a different unit of measure).

Well, I can't figure out what you call euro Accord sometimes...

H23A3 was put in the European version of normal Accord from 1993 to 1994. The car was described as 2.3iSR and was made in England. Later this engine was replaced by F22Z1 (2.2 SOHC VTEC).
This is the same engine as H23A1 (US Prelude) and H23A2 (European Prelude).

Accord Euro R is the name for a car on JDM only! It has H22A8 engine.
True Accord Type R is being made in Swindon UK with H22A8 engine 212HP, 209Nm.

Rover 623 borrowed the engine from Honda...
That's all. Hope it will clear things out.

Wrong, the H23a is the blue top, japanese honda motors dont end in numbers, the h23a3 is from the edm market and is exactly the same as the h23a1. The 5th gen had a 220 ps motor for the type s model in japan which still stamped as h22a but had a red valve cover.

Correct and I have the H23a3 in my car. No bluetop! Why does this always come up again after a few years?

I cant remember exactly what 23 i have i do know its the accord 23 block from japan or euro. if i can remember correctly its the h23a3 and its non vtec i would go look to clearify but my car is in storage cause the engine gave out on me. the 23 vtec is hard to track down but i have seen a few for sell at a price range of like 3500 or 4000

No more discussion is needed.


H23A1 = 4G USDM Prelude Si, 4G CDM Prelude SR, 4G AUDM Prelude Si, 91-93 AUDM Prelude SRS = 160hp/156tq, DOHC, non-VTEC, black top

H23A2 = 4G EuDM Prelude 2.3i = same stats as H23A1

H23A3 = 93-94 EuDM Accord 2.3iSR, Rover 623i = same stats as H23A1

H23A4 = 97-98 & 01-07 EuDM Accord 2300i = 195hp/160tq, DOHC, VTEC (these stats might be wrong, not much data on it)

H23A = 4G JDM Prelude S = same stats as H23A1

H23A = JDM Accord SiR Wagon (CH9) = 197hp@6800/163tq@5300, DOHC, VTEC, auto tranny, blue top

H23VTEC = Homemade frankenstein engine = H23 block + H22 head
