Ok i see all these ef/eg/ek and i own a 90 CRX 1.5, 89 CRX 1.5, and a 89 Civic Hatch 1.5. i do a lot of honda work and studying on it but i kept on seeing all these diff options and engine and im just confused. is there some were i can go to figure all these things out or someone please fill me in.

please help!!

 

88-91 ef
92-95 eg
96-00 ek
01- ep

These are just general codes...most of them dont hold true for usdm cars. Theyre just overused

 

Correct me if I'm wrong but...

EF = Pre 92
EG = 92-95
EK = 96-00

So your rex is an EF. Hope this helps.

 

your crx's chassis code is EF, 88-91 is EF, 92-95 is EG, 96-00 is EK

 

is there any exact way to tell if it is usdm or jdm and then what the diff cassis's are

 

jdm chassis are right hand drive
usdm are left

look at your vin
mine starts out - 1hgej8xxxxxxxx
1 is USA made
H is Honda
next is vehicle type
etc
EJ8 is my chassis code, meaning its a 96-00 civic ex. That section is your real chassis code. But all 88-91 civics are generally classified as EF (as said)
