I've got a slightly modafied GL-10 4wd turbo (stock turbo stock EA82) I've noticed when I get into boost, pretty much when I'm going full throttle, my tempature goes up 1 or 2 bars in a matter of seconds. I do have the digital cluster so thats what I mean by 1 or 2 bars. I've never had a water cooled turbo so I don't know if this is normal. I changed my coolant, but could this be a sign that my water pump or radiator is going to need replacing sometime soon ?
