take the fitting to your local earls/aeroquip store and compare sizes. Or just measure it yourself.

 

It looks like a -4An. What kind of turbo do you have ?

That "kit" appears to have a return that is too small. I have never trusted these oil drain fittings that are machined for NPT. Most OEM drains use a hose barb which has a much larger ID.

The feed might be fine. It is -4AN but is that NPT-AN adapter a simple adapter or a restrictor?

 

do you need a restrictor when using a 3an line?

its a t3 60 trim. yeah others have said it looks like a -4AN. anyone have a restrictor? here are some pics of my turbo and then the oil drain line is a 3/4" hole so its not that small

 

holy **** that turbo is crazy small!

 

if you find a restrictor that's for sale somewhere, let me know too cuz i need one

btw: how are you guys able to tell -4an from -3an? is there that big of a difference?

man, everyone disses the small turbos. this is a t3 60 trim. its going on a 1.6L. these turbos were used on the 3L nissan 300zx so this is the perfect size for a 1.6L. maybe even a little big. well soon find out and ill let you know

 

if im actually going to get a restrictor im just going to weld the nipple shut and then drill a small hole

 

i might just do that too then... which nipple are you talking about?

 

well like on the fitting that you screw into the turbo. ill just weld that shut and then drill a small hole.
