I was looking at using a 7A-FE sump, but found out that it isn't a easy fit to a 16v 4A-GE block.
So I'm looking into modifying a standard pan. Just wondering if anyone else has done anything similar and the pros / cons to different methods.

Seems the most common design is adding "wings" to either side to increase the capacity and baffling to help keep the oil down by the pickup during corning.
Heard bad things about trap doors getting stuck and starving the engine of oil, so kinda want to steer clear of those.
