don't go to attarco!! the person i bought my ek from got an "OBD2" d15b from them, he didn't know, i bought the car, i didn't know, went to get my car inspected by my mechanic, and he popped the hood and saw it, and told me it was an obd1 and couldn't even be in my car. i called attarco, to see if they would be willing to buy the engine back, and i got hung up on... long story short, i'd avoid them
