zep Posted July 26, 2007 Share Posted July 26, 2007 Hey boes! I have been reading, and it seems that I can not run water lines. And by not run them, I mean that it's really not that neccessary as they do about as much as a dead hooker. Is this true? Can I just not run them, cause that'd be pretty cool, or should I run them for the sake of it? Turbo is T3bb from RB25DET (r33). Cheers boes Quote Link to comment Share on other sites More sharing options...
Raizer Posted July 26, 2007 Share Posted July 26, 2007 Yeah its fine not to run them, id plug the water holes in the core though Quote Link to comment Share on other sites More sharing options...
Hemi Posted July 27, 2007 Share Posted July 27, 2007 nah dont have to run them they just help for more milage outta turbo i think , just take off the lines and like hellraizer siad plug everything Quote Link to comment Share on other sites More sharing options...
Rusted Posted July 27, 2007 Share Posted July 27, 2007 Water cooled was most likely for the sake of ceramic lifespan. Quote Link to comment Share on other sites More sharing options...
zep Posted July 27, 2007 Author Share Posted July 27, 2007 Yeah, I got soe advice from a Garrett dealer in Aussie. He said if it has the lines, then run them. Quote Link to comment Share on other sites More sharing options...
Hemi Posted July 27, 2007 Share Posted July 27, 2007 rofl , fair nuff i say , i say that so much at work lol such a hypocrite i relly think itd be for a longetivity of the thing rather then anything else to be honest, garret will say run it but its xcould be becuase #1 they dont want shit coming back saying turbo failure due to lack of cooling (after 50,000km or whatever warrenty is) or be like me and go ' i work on these things all fuckin day dont tell me how to treat/fix/service them ' stz Quote Link to comment Share on other sites More sharing options...

Ke36 Posted July 28, 2007 Share Posted July 28, 2007 yea im not running water lines on my vr4 conversion, with evo turbo alot of mitsi guys dont bother is a common thing not to run them general consenses is that they are there to help cool it the turbo down on shutoff etc, so aslong as you dont run your car hard as hell then shut it down quickly youl be fine, some say get a turbo timer others say just dont boost it hard for a few minutes before you stop driving while the car is running the oil does most of the cooling some garret ballbearings dont even come with water lines depending on the model Quote Link to comment Share on other sites More sharing options...
FIAT Posted July 28, 2007 Share Posted July 28, 2007 Put it this way, it can only be better, not worse to run coolant through the turbo. The plain bearing old T3 off my Lancia is water cooled so its got nothing to do with ball bearing, or ceramic etc. It takes a little effort but I always hook up the water cooling. People leave the water cooling off as they are lazy or its just too difficult. Quote Link to comment Share on other sites More sharing options...
84_S12 Posted July 28, 2007 Share Posted July 28, 2007 Expect to change the oil more often if you leave them off as it will be doing all of the cooling. Or get an oil cooler... Personally I would think it unwise to not want to cool your turbo, considering the hotter it gets, the more heat it transfers to the air charge. Not to mention all of the problems associated with core failure... Quote Link to comment Share on other sites More sharing options...
Ke36 Posted July 29, 2007 Share Posted July 29, 2007 all water cooled turbos i have seen run there cooling water after it has left the block, its going to be a 80 degrees plus anyway aslong as you have a oil cooler your turbo will be fine but as said you may need to make sure you do regular oil changes but if your not doing that anyway id be suprised factory cars water cool there turbos because joe average is lazy with oil changes, warming down etc theres no harm in watercooling it but it is definately not essential Quote Link to comment Share on other sites More sharing options...
peteretep Posted July 29, 2007 Share Posted July 29, 2007 if you are going to have problems cooling then it would be a bad idea to add in the heat of the turbo to the mix? Quote Link to comment Share on other sites More sharing options...
FIAT Posted July 29, 2007 Share Posted July 29, 2007 The water cooling hose for the turbo on my Lancia comes straight off the bottom of the radiator and then up to the main pipe to the water pump. Its the only car ive seen like that though. Using coolant off the block is fine. 80 degrees C is much cooler than 100-120 degrees the oil can get to, not to mention the heat transfered from the turbine. I agree its not essential on any turbo but its a good thing. Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted July 29, 2007 Share Posted July 29, 2007 yuh the 80 or so degrees is bugger all. oil tmeperature fluctuates massively under carying load conditions etc while water temp stays roughly constant, in cars. I'd run them. Quote Link to comment Share on other sites More sharing options...

Also, oil blow-by should be reduced significantly if the core has additional cooling Quote Link to comment Share on other sites More sharing options...
zep Posted July 29, 2007 Author Share Posted July 29, 2007 Sweet thanks guys. Definitely going to run them now, and oil cooler too. Just have to find place to mount/fit it. Quote Link to comment Share on other sites More sharing options...
lowlancer Posted July 30, 2007 Share Posted July 30, 2007 I was told that the Group B Lancers never ran them because it caused the coolant system to overload due to the heat they were generating Most likely bollocks Quote Link to comment Share on other sites More sharing options...
Mike-e Posted July 30, 2007 Share Posted July 30, 2007 I was told that the Group B Lancers never ran them because it caused the coolant system to overload due to the heat they were generatingMost likely bollocks so isnt edit - btw where were you on sat cunt all water cooled turbos i have seen run there cooling water after it has left the block, its going to be a 80 degrees plus anyway having had stropped a few turbo cars at night and owned a couple and seen how redmotherfuckinghot they can get 80 degree water would be like chucking one in a freezer. not saying you need lines etc because clearly you dont, but fuck, if i had them id sure as hell run them, something with mega fine tolerances spinning 60k+rpm @ 200 degrees plus needs all the help it can get Quote Link to comment Share on other sites More sharing options...

peteretep Posted July 30, 2007 Share Posted July 30, 2007 glowing red means something like 800 degrees(and that something is either wrong or that motor runs fucking hot and should have heat wrap)? was told that buy some hoe in the airforce, not sure if its true though Quote Link to comment Share on other sites More sharing options...
