I just got my VS 3582 JB twin turbos, they have the iron Vband exhaust housings standard T3 inlet. Your setup looks good! Those exhaust housings are nice as well!

Any reason you went with the 3an fitting and feed hoses? What are you running for drain -10an? I spoke with Viren about the 3582s GT35s .82AR and he recommended a -4an feed and a .060" restrictor for these Journal bearing turbos. I got some ICT billet T3 drain flanges with a 1/2NPT and I'm thinking of either a -8 or -10 drain.

Thanks for the kind words.
On the oil feed fittings, that's just what I'd been using on all my prior turbos(TC76, PT7675, ON3 78mm, ON3 84mm) I'm not running any restrictors on any of them. Just the normal diameter of the -3an fittings. So far, so good. I am running -10an drains. I ran -10 on all the other turbos too. I've been using a turbowerx scavenge pump in the past because my hotside positioned the turbos too low for a gravity feed. These GT35's are up nice and high where gravity can work.
Looking forward to the results of your build!.

Gotcha, thank for the response. I currently run a -4an with a .125" restrictor on my VS billet 78/75 single as viren says not to run any on the JB turbos. I also run a single -10AN drain on that. I figured these turbos are a good bit smaller so maybe I could step down the drain to a -8an but I already have a bunch of -10 fittings so its not really an issue. My build isn't happening for a long time (gona do a twin turbo 5.3 hot rod truck kit car) just gotta come up with 20k to get the kit. So I'm just collecting parts at the moment.

Def in for some results on your build!

I personally donít like using an fittings for drains.

my setup is as follows.

melling high volume dod pump
20/50 brad penn
4an feeds unrestricted
i return to the front cover bottom corner each side.

1/2 npt x5/8 thin Wall 45 barb on the cover and turbos
10an line, and my drains are basically flat.

i run around 50-60 psi oil pressure at idle 100# wot, with all my bypasses plugged. Plenty of oil pressure for sure. Donít really have a point to all this I guess, just joining in on the feed/drain conversation lol
