Just wondering if anyone out there has done this and where you got the oil drain flanges for the turbo and the engine block.

I just received my flanges from Vibrant Performance and even though it says that they are tapped for 1/2" NPT, the -10AN to 1/2" NPT adapter that I have won't fit. I'm starting to get frustrated as I need to get this together to diagnose my cars smoking problem before the dyno day on June 4th.

Anyone have experience with these parts?

I'm pretty sure that the block is a metric line.

I have custom lines for my oil feed/drain for my turbo but I have NO idea who made them or how.

You should gather all your fittings and take them and your measurements for the lengths of the lines to a shop that's reputable and have them make the lines. It's a lot easier. I make my own but without the stuff in front of me it's a little difficult. Sorry if this is no help.

I've done this. I purchased my drain flanges from ATP Turbo. The ATP flange is designed for a T4 and has a 1/2" NPT female thread. The feed I made out of a T3 drain flange from Russel. It is actually the perfect size to bolt to the stock turbo's feed flange and with a -10 to -6 adapter easily connected...On an FD I'm not sure what your feed looks like so you'll probably just tap it for an NPT thread and then use an adapter.

NPT threads are tapered so don't be surprised if it only goes in a few threads. Ideally it will go in 3/4 or so but machining differences between the parts can change that a lot.

I just used 2x T4 drain flanges with 1/2" NPT female threads. Then I used 2x straight 1/2"NPT to -12 adapter. Unfortunately with the HKS manifold and the -12 fittings, the soft line is maybe a couple inches long, making it very difficult to install. I am using -12 SS line with teflon inner liner, it's much cheaper than rubber multilayer stuff, but harder to work with.

Kenji, this may help you.

Thanks for the responses guys.

Aaron, the -10 AN to 1/2" NPT will thread in about a quarter turn, maybe a little less and then it stops. The guy at the shop told me to just put the flange in a vice and walk the adaptor in, but when I tried I could only get another quarter turn out of it. When I took it apart again, the thread on the adaptor was almost flattened out. I'm starting to wonder if the thread in the flange is even 1/2" NPT as stated by Vibrant.

Silverrotor, I took a look at the link and I've got almost the exact same parts, but for some reason mine just won't fit. I'm gonig to try a pipe fitting shop tomorrow and see if they have anything that can help.

I may just end up ordering from ATP Turbo just to save the headache. What is their shipping time?

Maybe PM Digi7ech? Him and I spoke via PM's a few times. He'll be able to assist If need be.

i dunno if it applies but i thought i'd mention that i cuz and flared the steel coolant line and fit it with a rubber hose, it seals better, its makes the turbo easier to work on/with. and i'd suggest it to anyone. could the same thing be true for oil lines, probablly.

however, i thought the oil return line has to have a streight downward slope otherwise oil would backup and cause the whole turbo oil system to stop flowing?

with a rotary build.. I make all turbo systems stand alone oiling.. safer and easier to control, it also allows the user to choose specific oils for the engine and turbo. as a stand alone system you can aslo build the hoses to suit your needs not to suit the jury rigged locations on the enigne.

That does not sound right. Even the tightest NPT fittings I have come across still go in a few threads at least. I recently had a 3/8" fitting on my fuel filter that was almost as tight as you describe. The adapter ended up being tight on the AN side as well so something was up at the machine shop that day. Do you have any NPT taps available? You could run the tap through the Vibrant piece to clean things up.

ATP has always been good to me. Generally arrives within a week if there are no border delays.

Well, seems that my problem has been solved. The info for the flanges in the catalog are wrong (typo I guess). It is actually tapped for a -8 AN fitting. I got a -8 to -10 AN adaptor and everything seems to be falling into place.

Thanks for all the help guys.

Do you have any more information about this system, or is it something you have fabbed yourself? I assume there's a high pressure pump, a tank, filter, cooler and the appropriate hosing. A little Google searching didn't turn up much. Pictures? It would be interesting to see how something like this is implemented, where stuff gets mounted, etc.

it's all in house stuff. you'll have to contact me on msn to get pics.
