I’m new to a compound setup, got a stage 1 turbo from Mark and it came with a remote oil feed -6 kit. I bought an old epr kit, it came with a -4 line. Is the -4 enough for the s475 or should I put a -6 on it. Last question will I have a lower oil pressure at idle then normal with the larger feed lines or am I overthinking? Emailed Mark but it’s after hours for him, I know I wil hear back from him Monday. Just picking others brains, thank you!
