im at that point where i need to start addressing the details of pluming(oil and coolant) the turbo. its a 1991 miata with a new garrett t25 turbo.
1)where on gods earth can i find a M10 X1.5(oil feed from block) to 4AN adapter?
2)does anyone know the pattern on the oil return whole next to the oil filter on the 1.6?
3)how exactly do you run the coolant lines? (ie. do you T them off existing coolant lines, and are these lines gravity fed? pics would be great)
4)what O.D. should i be running on the various lines (oil in, oil out, cool. in/out)?
5)does anyone know the oil out pattern on a t25?

if you can help with any or all of these questions i would greatly appreciate it.

 

1) I get all my an fittings at anplumbing.com
2) Tap your pan on the driver side for your oil return. Use push on hose fittings 1/2" NPT or -10AN fittings, depending on how much you want to spend.
3) Pretty sure its covered in the FAQ
4) oil feed should be -3 or -4AN, oil return should be -10AN or 1/2" NPT, coolant can be any number of things.
5) not sure on that one. 1/8" NPT maybe.

 

oil out = no pattern. needs flange.

 

Coolant lines are most commonly 5/16"
