I know that there's been a lot of talk about modifying sump, building big-wing ones, allready...and I love the idea...but...

In my spare time I'm preparing one 1.3turbo engine(used to be turbo, now it's gonna be N/A), and idea was to fully modify sump,making it big-wing, cause I dont like to do things if there's no really point of doing them I decide to test my sump
I put 1l of water in it and I leaned sump in every direction, and place where oil pick-up is placed, is allways well fed with liquid.

So...I'm pretty sure that there's no need for too much modifying sump itself,just making it big-wing to increase oil capacity.
What do you think?

You don't want 'wings' (ie: transfer boxes) on transverse sumps. Do something like this if you want to modify it, bulkhead with trapdoor and some static baffling here and there. There isn't much room and you need to allow for breather return pipe, dipstick and pump itself. Too much baffling and you won't be able to fit it.

The difference is this:
On a transverse unit the oil flows forward under braking but the engine is off-load and so can tolerate a lower oil level. Under acceleration it flows backwards but we want it to 'roll back' form the sump rear wall toward the pickup.

On an in-line motor there is a grave risk of the pickup being starved on turns so we place transfer boxes with gates to cause the oil to flow over the pickup on alternate turns. Looking towards the front of the car on a left turn the the left transfer boxes empties over the pickup and the right box collects the oil running to that side.

I always recommend use of a Moroso accumulator with a wet sump engine, no wet sump will protect the bearings from dry-run failure indefinitely. These systems are featured in GC V/W.
