Antimatter Posted June 26, 2008 Share Posted June 26, 2008 I know there will be plenty of "why would you" comments - but I would be interested to know if anyone hase used air cooled low mounts on a RB26... and with what results ( performance, longevity.... ) Again - please dont ask me why.... I am really intested in others experience with such an arrangement. Cheers...

GTR1993 Posted June 26, 2008 Share Posted June 26, 2008 Its not referred to as air cooled, its oil cooled, and generally speaking its not the end of the world is you dont hook coolant lines up to you garrett turbo. Lots of TRUST turbos are not water cooled. Link to comment https://www.sau.com.au/forums/topic/225696-air-cooled-turbos-on-a-gtr/#findComment-3974860 Share on other sites More sharing options...
R31Nismoid Posted June 26, 2008 Share Posted June 26, 2008 Anymore details on these air cooled turbos? Links etc? Link to comment https://www.sau.com.au/forums/topic/225696-air-cooled-turbos-on-a-gtr/#findComment-3974900 Share on other sites More sharing options...
paulR32gtr Posted June 26, 2008 Share Posted June 26, 2008 I hate those stupid bloody water lines on the GTR... would be a pleasure to only have to worry about hooking up oil lines (hate them as well though)... can't wait until foil bearings are used for turbochargers. I have run water cooled turbos without water before without any problems - I do remember hearing somewhere that timing your car down is more important with oil only turbos for heat transfer reasons.

stricnynel0s Posted June 26, 2008 Share Posted June 26, 2008 the issues with that is that in water / oil turbos, the oil cooling jackets are a LOT smaller, and mainly for lubrication compared to straight oil cooling, and yes with just oil u need to time the car or else the hot oil accumulated in the turbo seals sits there and cakes Link to comment https://www.sau.com.au/forums/topic/225696-air-cooled-turbos-on-a-gtr/#findComment-3975020 Share on other sites More sharing options...
r33_racer Posted June 26, 2008 Share Posted June 26, 2008 ohh yeh foil bearing turbos...exactly what i was thinking! I thought perhaps that was what this thread was going to be about haha. Just maybe someone got the title wrong guess not!

Antimatter Posted June 27, 2008 Author Share Posted June 27, 2008 yep - what he said sorry - oil cooled... Nismoid - I have a pair.... look pretty much like GTR turbos (the housings are GTR) but with a oil cooled CHRA. It has fins cast in where you would normally see a fitting for a water line.... Anyway - will try to get a pic. My reason for asking is I have a GTR that has just poped one of its ceramics... and I have these lying around and thought I might give them a go? My hesistation lies in "all that heat down there" and "nissan use water cooled turbos for a reason..." Its not referred to as air cooled, its oil cooled, and generally speaking its not the end of the world is you dont hook coolant lines up to you garrett turbo. Lots of TRUST turbos are not water cooled. Link to comment https://www.sau.com.au/forums/topic/225696-air-cooled-turbos-on-a-gtr/#findComment-3977038 Share on other sites More sharing options...
