How do the classifications EFX work, where X is a number? I understand an SiR is an EF8, but there are other EF ones, and there are some for DC, EP, EG, EK, EM, etc. Can someone give me a Honda classification system or family tree or something?

OK I have read the whole list some place,but I'll be danged if I cant find it.
OK I will try to answer this one "off the cuff".

EF9=(JDM) civic hatch SiR
EF8=(JDM)CR-X SiR
EF7=(JDM)CR-X Si
EF6=(JDM)CR-X with a dual carbed 1.5L
EF5=I do believe this was the civic shuttle(not positive)
I'm a bit sketchy on the EF1 -5 sorry..

ED9=(USDM)CRX Si
ED8=(USDM)CRX Dx
ED7=(USDM)civic hatch Si
ED6=(USDM)civic hatch Dx

The EG chassis code refers to the 92-96 body style civics(once again I cant find that super duper handy dandy list I once had) :(

The DC refers to the integra chassis code
DC5=The bad boy teg type-r

ahh I will finish this when I can..I'm searching for that list so I dont go misquoting myself.

DA5 is the 90-93 integras
DC2 is the 94-01 integras minus type r
DC5 97-01 integra type r

now the civics from 92-95 i dont know all of them but i know

92 civic 4 door lx is an EG8
93 civic hatch si is an EH3
94 civic coupe dx is an EJ2
96 civic coupe ex is an EJ6

those are the ones i have layin around my house i found paperwork with the vin for.

what that code is is part of the vin number. its the 4th 5th and 6th digits of the vin number.

4 dr tegs are DB's, my GSR is a DB8.

DC5 is an RSX, not an integra, as jfrolang mentioned.

Keep in mind the RSX IS the Integra on the other side of the pond.

Guys:A RSX IS an integra.

Oh and a DC5 is a teg type R as I stated.Although retagged RSX its still an integra.I just didnt say what year.
As far as a USDM crx HF that one befuddled me.I will look on that one.

I know it's an Integra. That's what I said.

DC5 is the 4th gen Integra chassis, aka RSX.

not a 3rd gen Type R.
I was responding to this:

And USDM HF is ED8, as already stated. Dx is also ED8.
