Thought i would post this in the drift section as this is what the main point of my car is, as it doesnt see too much daily use, more weekend beat downs in the mountains and on track drifting.

Looking at a garret t04s series turbo for my half bridge and its oil cooled only. Now i have been reading a bit around on the internet and most people are saying its only for keeping the turbo cool enough to prevent coking of the oil on shut down. Well thats why i have a turbo timer

other than that is seems like it an easier/cleaner install, and less work on your cooling system but i am worried about longevity, running it on a rotary due to our higher exhaust temps. i dont really want to run into issues at the track or anything along those lines.

So should i bite the bullet and shell out more for a oil/water cooled joint or will oil cooled alone be perfectly fine for my application?

 

if it's Garret and they designed it to be oil cooled only, i'd say your alright. as far as i know they don't build garbage turbos so they must have figured out a way to alloy the oil to cool the turbo relatively well and still have some life left in it. that's only a guess though. have you contacted them and asked? that'd be my first phone call/email.

 

Oil cooled only is fine. Like you said, water and oiled cooled is an added aid to resist oil coking and the chra locking itself due to hot shutdown.

Also it's there for bb chra's that use lower oil volume and NEED extra cooling.

Plenty of guys on here running oil cooled only turbos.

 

All my single turbo setups to this point have been oil cooled. I just take it easy the last mile before I shut it down. No need to use a turbo timer.

 

thanks for the info guys, i have been pondering just swapping over the housing to a BB 60-1 but this info is still good to have in my head

 

oil cooled to4r w/hbp here. i have no problems with it
