TO4 TURBO oil lines and coolant???
 

i am installing my to4b turbo on my engine,now i have a question for those of you who has a turbo other than stock on your rex.

OIL DRAIN. do i need to get a flange made for the drain adapter on the engine or do i tap the aluminum cover.

COOLANT.
do i get a flange made or tap the LIM for the turbo coolant feed.

i want to try not using gear clamps and rubber hoses,i rather have compression fittings or hard pipe connections.

what have you guys done.

For the oil drain i'm using a -10an SS braided line and fittings from http://www.2751engineering.com/ . The front cover was drilled and tapped in order to attach a -10an fitting.
