Single turbo oil feed line help

[leon]

Hey guys,

I\'m trying to make an oil cooler line for my car, I\'ve bought one of those Feed kits of fleabay with the 4an fittings but i then find out that the Rx7 does not have 4an on the standard Hardline.

I\'m wanting to use the existing hard line as much as i can to keep things neat.

Q1 what size is the standard oil feed hardline end?

Q2 what have people used to bridge the gap from there to the turbo?

Cheers
Leon :cheers
