External oil loop with accessories question.
Hi everyone, I know that the external oil loop question has been asked a million times, but I did search and couldn’t find anything relevant to my use case. Everything I saw said tap the side of the iron or use the turbo oil feed port.
I ordered some solid dowels for my engine, so I’m going to have to do an external oil loop. I am keeping my AC/PS, so I can’t drill and tap the side of the front iron, and I have a turbo so I need the top banjo bolt in place or an alternative turbo oil feed. What are my options here?
I was thinking I could mill out part of the accessories bracket so I could drill and tap the side. Has anyone tried this?
Finally, what are my options for alternative oil feeds?
Thanks for reading

not something we have had to deal with yet but we are soon....
this fitting may very well be the way https://www.fittings.space/gsa39-m14x15m-51 it would thread right into the front iron in the normal spot on top and then you would stack 2 of these https://www.pegasusautoracing.com/pr...asp?RecID=6557
or
this exotic fitting would work without a doubt

Would a 4an line flow enough oil to replace the stock dowel? the passage in the dowel looks much larger than 4an, but I think it’d work for the turbo oil feed.

After a bit of googling I think a 6an banjo bolt adapter would work rather than a 4AN, as that seems to be what everyone else is using. I think we’d be able to keep the stock oil feed banjo bolt and then loop the 6an to the filter pedestal. I didn’t realize that double banjo bolts existed, thanks for the lead

IMO any application where an external line makes sense is going to be for something so far out there that you're not going to have air conditioning or power steering on the car.
But that's just my opinion.
If you were going to go that route, it makes about as much sense to eliminate the internal oil passages entirely and run a Y from the oil cooler setup to each oil gallery.

I"ll be honest, an external line isn't super necessary for my build, but I figured since I'm rebuilding it I may as well completely overbuild it to future proof it. I only plan on hitting about 350WHP, which a stock engine can easily handle, but I didn't want to have to tear the engine down if I decided to go bigger. I didn't realize that these one piece dowels weren't drilled, but I don't want to buy a new one so I'll just work around it.
I like the idea of teeing off the oil cooler, but I'd need a remote oil filter for this, wouldn't I? And from the FSM's oiling system diagram, it looks like I'd still need to drill the side of the front iron where the accessories bracket goes to feed the front stationary gear bearing.

I spin to RPM where my redline buzzer stays on after an upshift, have no oiling issues, no loop line needed. RPM like that requires accessory drive that kind of negates having accessories other than a water pump and alternator...

i did this:
6an to the front iron feed
6an to 1/8 npt sensor adapter used to add 4an turbo feed
you can drill/tap another area of the oil pedestal for 1/8 npt or use another pedestal that already has the extra ports but I decided to use the tee here because the FFE pedestal 6orb port is filtered.

That is a really interesting little device! I like that it is extra complicated so that the large oil port feeds from the center and not the unfiltered outside.

here’s a pedestal with a filtered -8 ORB outlet connection, also has an additional -8 ORB inlet/unfiltered connection and a 1/8” FNPT sensor connection

I ordered the pineapple racing pedestal and was concerned that I’d be feeding my front bearing unfiltered oil, but it won’t. It has two filtered 1/4”NPT outlets, presumably for external oil loop and turbo oil feed, and a 1/8” NPT unfiltered port presumably for a sensor. And its shiny
