Default TWINS feed/return tips please...

Long time no see Car is nearing completion! Not exactly sure how to feed/drain the twin set-up. Here is the scoop:

FEED
--Already have a 1/8" NPT drilled into that fitting above the oil filter. The orifice on the fitting is pretty small and adequately oiled my T76gts, and ST80 on my previous set-ups. Can I just drill the fitting out a tad, and run a -4, with a -4 T-fitting at some point, with a -4 then going to each turbo? Will that be enough oil?
--Other ideas?

DRAIN
Can I run a -8 off each turbo into a Y-fitting (-8/-8--->-10) that drains into the -10 fitting I already have on my oil pan? Or is that set-up too small???

Thanks for your help!

1/8 sounds pretty pinner to me, I bet it could possibly work but I would definately drill and retap, I used a 3/8 in mine and its perfect, its as big as you can go with the peice pretty much and it seems like what it was made for. With a 3/8 I don't think you would have a problem linking them up. What type of scavenge pump ar eyou using or planning to use?

Are the turbos journal or BB?

-4 lines will be sufficient IMO, but you may need restrictors if they are BB turbos.

On the drain, I would use a -10 minimum from each turbo and I don't really see a problem with Y'ing them together. I've done it without issue for years.

-4 for the feed and -10 for the drain. You can t the -4 and -10. I have a t for my feed but I have two separate drains welded up on my pan.

Turbos are journal bearing. Looking to run a -4, with a T for the feed, and Y two -10s together into a single -10.

Anyone tried a similar setup and have it not work?
