I'm dropping a B18c in my EK. I have all the mounts that I need but do I need to replace the cast iron driver side mount (the part that has the two bolts that come out from under the cam gears) I have my stock one and I also have the one that came on the motor. Can anyone of these two be used or do I need a 99 Si one. TIA

 

I have a b18c1 in my 99 ex car. I just ordered the mount for a 99-00 si and installed it. You can also just drill the holes out a little bigger and use some kind of a thick washer for your nuts. i.e. two 1/2 inch drive sockets.
