Turbo eating coolant ? HIGH HEAT COOLANT ?
ok well my temperatures are fine, my enigne is re-built with new head gasket, i have a t25 turbo oil/water cooled,
im running normal 50/50 coolant ,
once warmedup and ran once at idel or vacuum it burns some coolant out of exhaust,
there no coolant in oil and temps are fine just burns a bit of colant ?
should i use high heat coolant ? does anyone ? can a turbo burn coolant ?
do i have my lines hooked up wrong ?
and again its only at downshifting or idal

well i uswed some racing coolant high heat 80/20 mix and it barely smokes now,
i think its my hg that i just replaced so , but i will block of the turbo coolant line and if its still doing it then i will towards winter replace hg and shave head, but if not ill save for the gt28rs.

Post pics of the lines going into the turbo, some of them have optional water holes. Mines got three, and I just saw a Solstice Borg Warner unit with four! I'm wondering if you got crossed up.

Even if the coolant passages were cracked, the coolant would simply mix with the oil and just ---- your bearings fast. You'd have to have bad CHRA AND turbine seal to get water in the exhaust from the turbo.
Furthermore, you will not cook your t25 without water. water does little to nothing while the car is running and boosting, it's simply to prevent oil coking after shutdown, as the water absorbs the heat out of the oil within the CHRA so it doesn't burn up.
The water flow through the turbo does not matter, and it would be hard to mistake the oil inlet from outlet.
I'd be more concerned about something like your new head gasket at this point, you sure it got torqued correctly? Downshifting and idle both = high vacuum, there's a clue.
As far as "high heat" coolant, the best coolant is distilled water, adding antifreeze lowers the cooling system's efficiency. Water has one hell of a latent heat value, antifreeze is not there to anti heat.
