Turbo oil feed pipe

[umpkin]

hi guys, i need to get things on the move with getting my T25 on the car, its looking like money isnt gonna allow me to get a mk2 engine (but im still hopefull) but i have a flaring kit for pipe, so i can make a pipe up to fit my mk1 that can separate easily, does anyone know what the thread is of the end that goes in the top of the turbo, so i dont have to ruin the pipe i have while i make a new one. cheers.
