I used -6 for the coolant and -4 for oil lines.
I could price it again this is what i used from memory
from coolant block on motor
2 x -6 to m14x1.5 @14
2 x -6 14mm banjos (use std banjo bolts) @20
3 x -6 90 deg braided @ 35
3 x -6 straight braided @ 16
1 x -6 90 deg male male @20
Then the oil side
i think out the block on motor
2 x -4 m12x1.25 @ 15
1 x -4 straight braided @ 20
3 x -4 90 deg braided @ 60 (billet)
2 x -4 M12 banjo @ 20
prices are approximates, but would be close. Be approx 500-600, i was able to get wholesale through speed flow as i buy heaps of this stuff so was alot cheaper, the 60 retail billet -4 goes to 35 wholesale.
Only think you need to check is the metric threads as i cant remember if they are 12 10 14mm etc.
This is only the lines under the turbos, the other coolant lines that go over the turbos i left metal.
