Regarding ignition, I believe it depends on what type of engine, effectively your distributor, and what fuel grade you run.
Do some more research in this, but I think (from memory) somewhere between 26-29 degrees is safe.

Once you got your idle and ign sorted, it is time to tune the WUR. This involves either getting it modified or buy an adj. unit.

Fourth edit :
While this is not Porsche specific, it gives a good understanding of the importance of tuning your engine properly:

Thank you Sir!

No problem

On my engine, 78 930, I measure and adjust the ignition advance at 4k rpm with vacuum advance disconnected.

You should have 12/1 full throttle or thereabouts.
There is more response and power higher 10/1. Your problem is the lesser of two evils I commonly see lately with modded cis cars though. Better yours than the ones that get too lean.

Got it now set at idle on 13.9 (had it set first at 13.5 but changed after test drive. Cruising at 12.1 and full acceleration 11.1 ... need to adjust the wur?

That's not perfect but it's pretty good. You could get an adjustable regulator and get better but it's not bad if you ask me.

No third and fourth if you use 930 box. Just cruising light load.

75PSI of oil pressure by 1800 RPM? That seems excessive.

It looks like you got more than 1bar/1000rpm. This seems excellent. I don't understand the 5bar above 1800rpm. This does not seem normal from my experience.
I would say your oil pressure looks good.

Hope it is for you because to much pressure could be made by another problem in your engine.
At least thats what they say in other threads.

Hi Guys

Question for you guys that have installed the Borg Turbo, is there a mounting plate off the hot side of the turbo similar to the K27? Thinking of order one, want to make sure there are no surprises.

Thanks

J
