You need to ask this in the RWD forum, no B18's or B20's in FWD/AWD.<p>But, it's my recollection that the two pans bolt up, but there are minor clearance issues around the oil pump. I dimly recall there's an extra cutout in the B20's oil deflector tray due to the size of the later pumps. Should be easily tweaked, if so.<p>Tom.
Thanks, needed to know, as I found out B20 pans are desirable to guys using them on 16V engines so they can "stand upright" to make room for Turbo. And I was pretty sure B-18 pan was pretty much the same.
