Oil Cooled Turbo

[OMY31T]

hi guys, im loking at a T67-25G which is oil cooled only. will this decrease the turbo life span? is it worth going oil only. it will be on a highmount setup, manifold is HPC coated, and i have a carbon fibre bonnet which basically vents direclty at the turbo for extra cooling. just wondering if there is any dis advantage to switching to oil cooled only.

cheers.

just make sure you cool it properly before you switch car off... otherwise they're fine, no less reliable that water cooled (some might even argue more reliable, but let's not go there)

ps. highmount + carbon bonnet in Melbourne... good luck:)

Plenty of turbos from the 1980's that are oil cooled only

There is no issue with it.

Bush bearing turbos run much larger oil flow/galleries etc. So heat is removed that way.

Good thing he will have lots of oil flow - but good to lube up ones bottom.

What about an oil and water cooled turbo but only running it as oil cooled. Only cause it would be on a project car and have no water lines. Would i have to bung up the water holes/threads on the turbo if not used or leave them open? or that would be a stupid question cause it would get dirt/dust etc inside the turbo.

If it has fittings for water cooling I'd be using them mate

[R31Nismoid]

if it is ball bearing.

MUST use water lines as well.
