There are 2 styles of the Moroso Oil Pan?

I'm sure I never will find the thread but a year ago or more someone posted on ET. He stated that he designed the pan while working at Moroso. He said the pan was originally designed for the Lotus but later changed to fit the Celica. I always wondered why the sump was so shallow under the last 2 cylinders. I assume the celica had some interference there. Funny, I don't recall the stock oil pan being that shallow in that area. As far as the tray difference, mine was the one that's tilted toward the rear of the car (bottom photo). It didn't look like a great idea to have no oil running to the front kickout of the sump. Remember, the flange of the pan tilts toward the rear of the car. I just cut the front part of the tray off and tig welded a new piece on aimed downward.
I might add that as the pan sits on your floor, that's pretty close to how it sits on the engine. Quite an angle. In fact the oil is pretty much up to the flange at the back of the car. I would prefer the deeper pan with the tray sitting level, not the one I got. It's expensive and frustrating not having the proper pan when you're buying a new pan because you're concerned about oiling issues. I considered adding material to deepen the shallow sump. It should help with crankcase pressure and windage since the pistons travel up and down so close to the pan and the crankcase is narrowed way down also.
Also, that shallow sump won't do as much good in a long high G left hand turn as a deeper one. Nice photos.

I'll have to double check but I am pretty certain that mine is the "deep" one, like the top one here:

I know my system including the Accusump hold nearly 8 quarts and with that shallow one I don't see that being the case. I will have to double check next time I am under the car.
