I bought a 99 SI and the check engine light came on. When I took it to Honda they said I needed a oil pump because my motor was a JDM. The engine has b16a with no number after the a so they said its not american made. Had anyone had the problem with the oil pump on a JDM??

 

jdm motors usually lack an oil pressure switch (located by the distributor, by the vtec solenoid.) do u live in canada? if u dont, u got jacked. someone replaced ur stock motor with a jdm one. weird.

 

I always thought that was how you tell the JDM motors from the USDM ones.

My friend got a JDM GSR engine and it just says B18C

 

If it was usdm it would say b16a2. The motor you have is probably an early 90's jdm crx or integra motor. I think you can tell by the number below the b16a.

 

you can tell what year it is from by the date stamps on the head.

 

yr of the motor usually is 1yr before the yr of the car
so a 96 comes out of a 97...
(9 times outta 10)

 

its not a matter of JDM or USDM that makes the difference. i suppose they used the same factory pump manufacture...

its probably from wear and tear due to aging since it could be an older motor

 

Isnt JDM motors better than USDMs? They are more powerful? A EDM B16a2 motor has 160hp, and the JDM has 170hp. Difference

 

Yeah, but this motor probably has triple the miles of the original.
