Hello everyone, first off..PLZ STICKY THISS PLZZ!!!
Second.
Unfortunately, there are more than 30 images so i can post no more pics. Please click the links anyway if you still wish to see it.
I have done much research and to make life easier for everyone i thought I'd start a thread on the differences of the '88-'91 EDM and JDM CRX's, and I'll even add some USDM stuff. I will say none of this stuff is my own, obviously, i am just putting it all in 1 thread.
So here we go, from the top!!... PLZ feel free to add and comment.
MODELS (Variations)
All CRXs were made in Japan.Even though our CRXs (USDM) were made in Japan, each country/ market
had it's own variations. So the ones for the US were labeled as USDM, the ones for Europe were EDM, Japan was JDM, etc etc etc.

JDM Motors (1.5, Si or ZC, Si-R)
ZC is the badge of the JDM ZC. Serial # below stamp: starts with 2 means its from a Civic/CRX
3rd gen DOHC ZC - black valve cover - came in 88-91 JDM CRX Si and Civic Si
D16A9 1.6 16V DOHC PGM-FI 1595 137hp@6800rpm 108tq@5700rpm '88-'91 Civic/CRX Si (JDM)
B16A- JDM 1.6L DOHC VTEC- 89-91 CRX Si-R (157hp)
D15B - SOHC twin carb- 90hp
EDM ( JDM DOHC ZCs, are the same as EDM D16Z5,A9)
(EE8)B16A(1)-DOHC VTEC (1-6i-VT) Honda CRX 1.6i/VT 1989-1992
(ED9)D16A9 -(No Cat) (1-6i-16) - DOHC - 130 hp (88-89 Civic/CRX)
(ED9) ^^SAME^^ w/ cat -D16Z5 DOHC (1-6i-16) - 124hp (89-92) CRX
ECU's
1989 D15B JDM CRX 1.5X SOHC ECU - PM4
1989 D15B JDM CRX 1.5X SOHC ECU - PM4
1990 and onwards had a revised ECU, a 1991 model has an ECU model (37700-PM4-914). The 1990 onwards ecu's seem to run a lot smoother, the Rev Limiter seems less severe as well. However they do seen to have less torque low down the rev range.
1990 D16A6 US CRX 1.6L SOHC ECU - PM6
1989 D16A9 EURO CRX 1.6i-16 DOHC- PM7
1988 ZC JDM CRX SiR DOHC - PM7
1990 ZC JDM PM7
1990 and onwards also had a revised ECU, The revisions mainly effect fueling at low revs. There is a slight lack of torque but the whole rev band is a lot smoother. The rev limiter was also revised, early 88 ECU's had a very servere rev limiter.
