I had a recent post about how this b*tch uses some other size oil feed fitting than the majority of Garrett turbos (still don't know what the hell it is but it isn't 1/8npt) and now I'm starting to see that it's leaking some oil through the seals.
Ok, some people are telling me this turbo from the single turbo 300zx's uses a t2 CHRA. Does anyone know for sure? If it happens to be a t3 can I find a CHRA from most any Garrett t3 and use my housings? I know the wheels would have to be the same size.
I already have a nice little downpipe fabbed up with a special flange Weir Racing made to work with this turbo since it's some funky 5-bolt. I don't want to have to fab another one.

 

take some pics.

 

any chance I can get a copy of that flange, I think I might have a similar turbo

 

What year 300zx? 84-87 were T3. 88-89 was T25.

The oil feed flange can probably be bought pretty easily.

I actually have some of the wastegate housings for those. They're the 5 bolt pattern and work with the internal wastegate. They're heavy cast bitches.

 

did you try what i told you last time? you will never find that thread at a hardware store. trust me ive tried. you have to take the stock fitting off and take it to them so they can make some sort of adapter for you.

 

---- all that ----.


I tapped mine with a 1.8NPT tap and blew the turbo out with compressed air from both directions to ensure there were no metal shavings left ion there. Then i ran a 1/8npt to -4an SS earls line (because im a gangsta) to the T on the back of the block.

Nate, contact Weir Racing for a flange.
It turns out I have a t-25. For those of you that have the same turbo the oil feed fitting is a number 4 IF (inverted flare)
A local hose shop had a male -4an to #4 IF. They hooked me up with a teflon encapsulated ss braided oil feed line for $18.

 

i have a 300z turbo as well.. but this is the t3..





I'm having some problems as well, with the pressure fittings on the compressor housings argh! as well as the water fittings.. can't find anything that fits...

its a t3 60 trim, .52/.63 ar
