Due to photo bucket fucking project threads across the internet I don’t have the phot that speaks a thousand words.
But.
There is a big chunk of alloy that hangs down and locates the sump to the gearbox. These don’t line up with a t9. There is loads that needs grinding out to clear the starter.
My flat sump held just under 4.5L. I would have liked a little more. In fact I am making another and will aim for a round 5 L like the race line sump. With yours I would make it flat at the front with a rear bowl like anything commercially available.
Not my photo, and I guess this is a modified cvh sump but you wand this shape with the bowl at the back.
