ok guys im lazy and tired im not searching this, and this is becoming a close knit family so i doubt any of you care if i just post a question with out looking,

the stock t25, does it have coolant lines in and out of it !? my car is too far away to go look, the fsm says it does but its vauge to say the least !

im putting in my HKS gt turbo this next week it has the oil lines, but no coolant lines they are open on the turbo ! will i need new lines, or will the stock ones, if it has them mount to it ? can i run the turbo dry, if so is it a bad idea !

thanks guys jon

Stock t25 is water and oil cooled! Fittings are there already.

As far as i know u have to change the oil feed line for every other turbo(t28,t3 etc.), don't know about water lines if they line up or not.

assume the oil line is coked up and get a new oil line. HKS sport GT turbos in their catalog don't come with any new water lines, this would lead me to assume they hook up to the stock water lines. Being as the factory and HKS turbos are both Garrett products it seems a safe assumption.
