If so, I really need some information from you.

Model/Trim level
Market (JDM, CDM, USDM, UKDM, EuDM, AuDM, SADM, etc)
First 10 characters of VIN
Engine code
Transmission code (if MT)


This is for my EXTENSIVE research charts. Unfortunately, I have accurate data from 1973-1985, then 1987-2010. I just have a gap with 1986.

Um what is this about? Asking for vin numbers sounds a little funny.

E-AT_me

i have an 86.. but that's some personal info!!

Kronn 98SH

The first 10 characters of the VIN contain nothing specific to YOUR car. It just tells where it was made, what kind it is, what kind of transmission it has, how many doors, etc. The last 6 characters of the VIN contain the only data specific to your car, the serial number.

If you'd like more information about the purpose of this, just search for the threads I've created. If you still think it sounds fishy, that's just leftover odor from your rendevous last night.

Here, read this. It might help you:

eh. i'll get you mine tonight when i get home from work. no biggie.

baduy001

i got one, hb, called here SB3 (CIVIC WONDER)

I own a couple..

Both are 1986 Honda Civic Si Info is the same for both
Market: USDM
VIN: JHMAH5339G
Engine: EW4
Tranny: GW

E-AT_me's info should be the same. Unless he decides to use the engine/tranny codes for what is currently in his car.

Kronn 98SH

Thank you very much, Control.

Anyone else? Maybe someone with a different car?

Only difference is CRX is jhmAF5 AF5 = CRX chassis code, AH5 = hatchy chassis code, my trans says either GM1 or GW1

Kronn 98SH

No, AF = CRX 1.6 Chassis Code. The 5 merely represents the kind of transmission. You didn't read my link.

Your transmission is the GW.

1grex

Hmm I have the 1.5 EW engine & my VIN is AF no doubt

Kronn 98SH

Sorry, my manual had it listed backwards. AS = 1.6, AF = 1.5, AE = 1.3

You have the EW3, correct?

1grex

Yeah '85, '86 is EW3 & '87 is EW4 but are identical engines (talking USDM Si's)

Kronn 98SH

To give you an even better idea of what I'm doing, here's what I've been working on for about the last month or so.







I have another 75 pages that I'll be posting up. I'm almost done but I saved Civics for last. That damn car spans 3 ****ing letters in the alphabet, something like 150 different chassis codes, with 8 different trim levels per code.

Kronn 98SH

According to Helms, EW4 = cat, EW3 = no cat.

1grex

WOW that is extensive; catalytic converter? ^

Kronn 98SH

That list is nothing, you should see the other 75 pages. Anyway, Helm's simply says "catalyst", which typically means catalytic converter, but who knows.

ControlNode

Nope. EW3 is the 85 CRX Si, EW4 is is 86 CRX/Civic Si, in 87 both the Civic and CRX Si models got the D15A3 (same as the EW4, just re-badged for updated ID system).

Most of that info is already covered on "red pepper racing" (remove the spaces and add ".com")

But all of those AH, AF, AK, AG and so on chassis codes for the Civic/CRXs ended in 1986. In 1987 they got the EC1, EC2, EC6, EY1 and such. The cars didn't change between 1986-1987, just how they were identified.

Kronn 98SH

Thanks again, Control.

I just went out to the parking lot to look (I'm at work LOL)
JHMAF5331G, EW4, has a cat

1grex

Damn I knew that, its been a long day, I quit, sorry for the bs I'm takin' it to the house

Kronn 98SH

That must be US only.

ControlNode

May have been.

My USDM FSMs are:

1. 1983 Honda Civic
2. 1986 Honda CRX
3. 1986 Honda Civic
4. 1987 Honda Civic
5. 1987 Acura Integra
6. 97-00 Honda CR-V
7. 98-99 Honda Accord

My USDM ETMs are:

1. 86-87 Honda CRX
2. 97-99 Honda CR-V
3. 98-99 Honda Accord

I also have an 84 Civic/CR-X CDM/EDM FSM. It shows similar to data to the 1986 USDM FSM, but with 2 new engine codes (ZA1 and ZA2) for a 1200cc.

Kronn 98SH

FSM? F-something Service Manual. What's the F?

By the way, I want those.
