hi guys, newbie wants to ask here.. i've just done an engine swap to my a31 cefiro.. the stock motor is an rb20e and i swapped it into an rb20det.. but somehow the oil pump is broken.. and it is impossible for me to get an OEM rb20det pump here, since i'm in indonesia.. do any of u guys know whether rb20det and rb20e oil pump is the same..? thx mate
