h22 block code

Post by **Drax** » Wed Nov 13, 2013 4:28 pm

below where is says H22A or H22A7 etc.. there's a number like 1xxxxx or 4xxxxx, does 1xxxxxx mean a h22a 200bhp BB1/4 block and 4xxxxxx mean a h22a 217/220BHP BB6/8 block?

That's just the actual engine serial number isn't it, with no further meaning?

The numbers show the combination of engine, gearbox, and serial number:

^ what Gladys said.

Mine matches up with what's on the vin thing, mine starts with 1 and is H22A8 so...

Interesting...

Just looked at the 4th gen service manual and all the supplements. That's what the first manual says, but the supplements show something different. The link between engine number and transmission was dropped and it seems that the first number on the engine serial number then relates to the service manual supplement that covers it . The manual doesn't say that as such but...

First supplement (11/92) shows: "H22A2: 10000001~"
Second supplement (11/93) shows: "H22A2: 20000001~"
Third supplement (1/95) shows: "H22A2: 30000001~"
Fourth supplement (10/95) shows: "H22A2: 40000001~"

Rather obvious link, no?

right so does that mean if its a h22a with a 10000001 number its going to be a bb1/4 fourth gen and not a bb6/8 fifth gen as surely that would be something like 6000001?

although that doesn't match up with Donalds a8 starting in 10000xx

does it just distinguish between H and F series blocks only?

this is for an engine on its own, not in a shell otherwise id look at the VIN instead.

Don't know for sure about 5th gens as only have one manual (no supplements) and it's USDM manual for H22A4 engine type only.
There it shows one number at the start is for standard lude, a different number at the front is for Type-SH.

Donald's H22A8 starting at 1 seems fine to me, because it doesn't start H22A2, so it makes sense they would start each different type from the start again and clock up each one in line with supplement issue?

@Thebusofwoe do you have any inside info that would help for 5th gen engines?

This.

If you want to be 100% positive on this numbering business then my serial is 10000018 preceded by H22A8 (can't remember how many zeros tbh) and is Jan 99 on the V5, so one of the first A8s, so it makes sense when you look at the low no. serial. I'm sure if we can find someone with a 99+ 5G with the original A8 then a comparison can be made providing V5 is correct etc. Only ones I know off the top of my head that fit the bill @Doggo and Merlin.

But yeah, it makes sense that it goes back to 1 with each engine type.

Couldn't tell you what's what with the H22A and 5Gs, ask some of the JDM boys.

Interesting one. I could find out tomorrow at work but i have always understood that there is an engine code, dictates engine type then a serial number. I mean wed have to compare the 4th gen manual with the 5th gen one and see what it means. What i do know is Honda did change the meaning of engine/serial numbers from time to time.

I think the 5th gen manual is on MARIS so will have a look when i get back from Tesco lol. (dam 4th gen isn't tho)

OK. Thanks for tagging me in, Donald.

I'm a bit hazy on this thread as I started early on the grog tonight, but from examination barely incontemporaneous with this post, mine says:

Block: H22A8 1000085
Plate on car also shows 1000085 and BB8
Date of First Registration on V5 (UK) was 30.03.1999

Also got everything else in paperwork if anything needed - VIN, Warranty Start date (as above), Model Code (KF8), Final inspector's name (Komatsu) (He was left handed), Final inspector's Daughters name (Kimiko) (Bit of a goer apparently), Capital of Outer Mongolia (Ulan Bator), Who's winning in car numbers out of JJ or Wurly (JJ. Currently) etc...
