what size fitting is the oil feed on my turbo? td04 from '02 wrx. i have the fittings/lines for oil drain and coolant feed/drain, but i didn't get oil inlet. help me with this.

 

Well what do you want to use? -an fittings? more than likly its metric and its designed to work with a banjo bolt, so you would have to tap it out. otherwise, you can use the banjo bolt w/ pipe, cut it off, flare it, and just double hose clamp it with some high pressure hose.
