R33 & Gtr Turbo Oil Drain Sizes

[nicr4wks]

Hi Guys,

I've recently bought a turbo for my gtst that came with an oil drain that looks like it's off a gtr.

The stock gtst drain will not fit as the flange is too big at the turbo end. The RB26 drain will not fit as the tubing is shorter and skinnier than the stock gtst one.

I won't be near the car again for a few days to measure and I'd like to get everything ready to go when I'm working on it next.

Does anyone know the diameter of the tubing on a stock 33 drain, and a stock gtr drain so I can find the fittings required to mate the two up.

Cheers.
