Can someone help me with this turbo fitting?
Ok, i'm almost done with my turbo setup on my 99 Si.
I bought a 1/8 NPT to 3AN 45degree fitting for the feed line that goes into the turbo. The fitting was going in kinda tight, but I made it work. Connected the line, started her up. My line was leaking. Doh! So I fixed my line, and reconnected it, and thats when I saw that the fitting became loose and came out. The threads on the 45degree fitting were kinda toast. The turbo is not 1/8 NPT like my speed shop guy thought.
So I had a 3AN piece fitting laying around that I tried threading in to determine the size, and it fits fine. It threads in all the way, and somewhat tight I think. Is the size on the turbo 3AN?! So I went back to the shop and he sold me 2 fittings that would work, and we would use an O ring around the AN fitting so it would seal on the turbo. The problem is I went to screw it in, and it was too tall and hitting the exhaust inlet flange. Crap.
Anyone know what size fitting this is on the oil feed on the Nissan turbo? 3AN??? I know it says .48 on the exhaust, and people said they think its .60 on the compressor (2.25 inlet), some say it came off a 280ZX or 300ZX, or possibly an SR20 motor if that helps. THe turbo is also watercooled. Here is a pic
