Hey for the feed, it says either 1/4 or 1/2Npt but I heard the stock turbo isn't tapped for these, can i just use an oil inlet flage adapter that is tapped or machined to 1/4 or 1/2Npt?? What should I do to fit the adapter, measure from center of bolt hole to center of bolt hole and the bolt size? I've never replaced stock lines with braided steel so any help would be appreciated.

This is for an '87 TII (S4), I'm sending the turbo out to BNR to get the watstegate ported and the turbo upgraded to Stage 1. Thanks soo much.

 

The stock oil feed pipe is two-bolt flange.
I can't confirm if the hole is tapped.
You realize how BIG 1/4"NPT or 1/2"NPT is???
If it happened to be tapped, it can't be bigger than 1/8"NPT...

this is what i'm going by. thanks for the heads up. let me know what you think. BNR said it wasn't tapped for NPT thread, so it might be like a Metric Pipe Thread , like 12 x 1.25 or something, I don't really know, I'm gonna end up doing a pretty big project ont his car ; turb/wastegate/lines/fuel system(still need to know how to hook up Walbro 255 to -6AN lines),etc... it just keeps sucking the money right out of my bsnk sccount but i don't care, she'll be tough one day.......

seriouslt though any rotor guys that could help would be greatly appreciated. Thanks again.

 

my bad it says 1/8 or 1/4 sorry

edit: though i think that quote applies to T3 or T4housings, I think Stage 1 uses stock housings??

what is the stock inlet threaded for???

 

The stock oil inlet is not tapped.

 

ok, so then an oil inlet flange with machined -4AN fitting ??

 

That will work. You can also probably tap it for 1/4" NPT.
