Would it be easy to modify a 13b to be orientated so the spark plugs are faced down to the ground and the intake/exhaust side face up to the sky? Has it been done before?

There would be a much lower center of gravity to the engine and i believe the oil distribution might be improved.

Is it a problem with the oil sump/pan being too close to the spark plugs an issue? we could probably run a dry sump though.

I fairly new to engines and how they all work.
I was also wondering this:
When my cars engine is running it reads a certain amount of oil pressure, when you rev it, the oil pressure gains appropriately. I am wondering how the oil pressure does not force the dipstick to eject?
I have no idea! please help, i am interested to find out. I am aware this may be a dumb question but let me know if it is actually a good question so i can feel normal.
If i did not post this question in a good section of this forum let me know so i can re-post it elsewhere.
Thanks.

 

essentially mounting the engine on it's side?

we'll have to agree to disagree with the "much lower COG-thing. i just don't see it. the length-width dimensions of the block are not TOO different and with the intake and exhaust, it should be as tall or taller - unless i'm misunderstanding your question. also, i'm curious as to how you figure it will improve oil distribution.

the dipstick goes directly to the oil pan. the OEM oil pans in rotaries are isolated. it only serves as a reservoir and common beginning and end point to the oil circuit. it doesn't see pressure - at least it's not meant to. likewise, it shouldn't see any crankcase pressure either.

i've seen an old Honda 3-valve engine shoot pop it's dipstick when revved though.

 

I bet he looks like this...

its not a closed system, the oil in the pan is not pressurized. its only under pressure from the exit of the oil pump to the bearing.

 

I wouldn't do this!

1. You wouldn't have proper oil drainage from the rotors.

2. You would easily flood and foul the spark plugs because they would be sitting is a pool of oil after each cold start. Any oil injected from the omp or premix would always migrate to the bottom of the rotor housing because of gravity. Your plug holes would always be full of oil/fuel.
