Tapsa Finland 0 Posted August 22, 2007 hey guys, could you give me some advices.. i'm gonna add a watercooling on my turbocharger, and i'm thinking that where would be the best place to take the hose into charger from and then take it back? should i take it to turbo from between the engine and the thermostat and then take it back to between the cooler and the engine? am i totally on wrong tracks here? every advice is appreciated a lot!

Kevin Bacon 5 Posted August 22, 2007 Not sure what you mean by "adding watercooling"? You can't 'add' water cooling to a turbo, the centre section has to be cast with the water galleries in it at the factory. What engine is it going on? If a VR6, you can use the existing throttle body coolant lines. If not, drill and tap a core plug at the back of the block on what ever engine and fit a barbed NPT fitting for your water feed, and the water return feed back to the expansion tank.

Kevin Bacon 5 Posted August 22, 2007 Ah OK that makes sense, so you're making up a hybrid turbo? 8) The 1.8T already has water line feeds, can't you use those or did you not get all that with the engine? Yeah you can take the water any where from the main flow, perferably before the thermostat otherwise the turbo won't get any water until it opens. I suggested the core plug as it's very close to the turbo and there's always water flowing round the block with or without the thermostat... Quote Share this post Link to post Share on other sites

Kevin Bacon 5 Posted August 22, 2007 Yeah they are blue coloured if I remember correctly and one is up on the top left side of the engine near the water expansion tank. It's been a while since I looked at 1.8T properly! Quote Share this post Link to post Share on other sites
