What are some common places to get and return water for a turbo on a b-series (b17a)? I've got a new oil cooler installed - could the lines going to the built in oil cooler be bypassed to this instead? I believe both inlet and outlet on the turbo are 3/8" pipe thread.

 

hydraulic and pneumatic industrial supply house, they can make hose in any size with any fitting you need.

 

i think hes asking where on the car...

 

then I still dont understand what he wants....does he want to run oil to the water cooled CHRA ??? or does he want to run an external water pump for the water cooled section?? then still go to a hydraulic supply house for an electric water pump and hoses. I do not suggest using engine coolant for the turbo.

I am asking where to get water to send to the water-cooled portion of the bearing housing. Would I be better off taking it from the stock oil cooler or the TB?

 

actually, i'd like to know about this too as my IHI RHF5 ballbearing turbo also has two holes on it for water cooling, yet i'm using the turbo without the water lines connected at the moment (people telling me its not really that necessary.. (?!?!)) Some pictures would be nice too

 

I would highly recommend using the hooking the water lines up, especially if they are already there. Having a water cooled bearing section will keep the oil from reaching the temperatures that it can coke up at.

 

I am hooking up some water lines for my turbo right now actually. I will put up some pics in an hour or two.

 

Ok, I just used cheap lines from auto zone - we'll see if they hold up around the turbo. I just ran a line from the thermostat housing to the turbo, and then a line from the turbo to the throttle body. I didn't feel like bypassing the throttle body, so coolant just flows like this thermostat --> turbo --> throttle body. This is in a prelude but I don't think it matters that much. If anyone sees a problem with this set-up, please let me know.

Lines for the turbo are the newest looking ones.
