I'd like to put a dry sump on my A14, mostly so I could lower it several centimeters. (It's not in a Datsun.) I can do it by moving the engine back (which I'm going to do at some point, because that also helps the car's handling) but I already have a modified mid-sump B210 pan on it, and the bottom of the pan is at the same height as a frame cross-member, so dropping it more means the pan takes the damage if there's a debris encounter. Hence, I'd like to put a flat pan on it.
What I'm thinking about is not using a traditional multi-stage mechanical oil pump, but instead using several electric fuel pumps as scavenge pumps, because I can mount them anywhere, and then using a single pump (either external mechanical, or possibly by plumbing the sump the scavenge pumps feed into through a hole in the side of the oil pan into the pickup for the stock oil pump) to do the job the stock oil pump does now.
Thoughts on whether this is dumb or smart or interesting or viable?

I guess you could use something like this:

But you would need to check and make sure that the pump is able to support the required flow or the org. pump so you dont starve it? But that's the obvious part...

Sounds like it could work

I have a couple of sumps... proper dry sump ones
I'm going to try set one of my engines up for this and see how it goes
Same reason... to drop the motor into a better position

How far the motor can be dropped for a lower CoG will will be determined more by the flywheel (and box) than the sump.

Tilting the engine would help also then could have a serious spaghetti style exhaust header and carbs would have longer inlet options (manifold length, filter shape and velocity stacks etc)

Don't ever cheap out on a dry sump pump.

This is the type of mod that you don't cut corners.

Proper setup as shown.

Why not just build a heavy duty sump guard; look at some rally cars, they tend to have guards that you can use to jack up the car.

Pretty setup
I'm only running 2 scavenge lines

Heavy duty sump guard might work. There's another frame rail that I'm hoping I can set the motor on, that'd act to guard the flywheel.
That scavenge pump is a _nice_ setup.

Love to see a CNC 2 piece dry sump pan, 2 pieces would cost less on materials and be easy to service clean and add strength (could even do as model T owners do to their 3 bearing engines and add 2 extra mains using the pan for A10 engines needing boost and 12000rpm)
