If my X51 is running backwards, I would be 100% interested in a tandem scavenge if economies of scale would help your project?
See the TTP item below, I also have pictures of it broken down if it helps. Autofarm used the TTP in the early oversized Caymans they produced.

I have the original Autofarm development Cayman RS fitted with their Silsleeve 3.7l engine. Looking back through the history that came with the car it ran very hot initially, so they fitted a front-mounted oil cooler, which seemed to improve things. They fitted the obligatory deep sump but there was no mention of the X51 oil pump / TTP Oil safer kit being fitted.
For reasons that are not clear, the front oil-cooler was removed just prior to sale, so little did I realise, but I was put right back to square one with a car that ran massively hot.
To cut a very long story short, a combination of input from RPM and Parr has now left me with a front GT3 radiator, 997-sized oil / water heat exchanger, a rear mounted external oil cooler and a TTP Oil Safer kit fitted to both banks. I had never experienced any obvious issues with oil pressure or surge on track, just high water and oil temps (the car is almost exclusively a track slag), but Parr convinced me that it was a prudent precautionary move. Either way the deep sump, bigger heat exchanger, external cooler and TTP kit will have added a meaningful extra amount of oil capacity to the system which hopefully is helpful for temperature management at the very least.
It has proven to be a hugely expensive, but interesting, journey to get to this point, and whilst a 911 has fewer cooling issues than the Cayman, I strongly suggest that any capacity increase is accompanied by significant extra cooling of both oil and water. Whether the TTP kit is needed on a road car is a fair question, but Parr insist on them for any M97 engine based track car. For preference they also fit an Accusump system, but that was far too intrusive in terms of using up boot space to make that a viable option for me.
