im gonna run a t25/hf mani, set up on my z6, my question is can i block the coolant lines, or do i need to use them?

 

No need to block them, only leave it unhooked, but if you use them that helps to increase the life of your turbo

 

Why run them it takes a hole 5min

 

If a turbo has coolant passages, run coolant.

The jacket sorrounding the bearings is designed diferently than one that just runs oil. Turbos with just oil have a lot more meat around them to dissipate the heat. You'll cook oil.

It all depends on how ghetto you are. It will work fine without, but not for years like it should.

 

Heat in cheap *** turbo= oh well ---- happens. Adding even more heat to my engine coolant=eh not so much

 

Personally, I'm running a T-25 turbo also, and it would be in the best interest to run coolant lines. It should be very easy to find a place to tap into the cooling system. You can use probably some 3/8' line to run to it, like trans cooler line, plus like others have said, extend the life of the turbo. ----, it only took me 30 minutes to run my coolant lines.

 

Oil is made to get hot. Just remember to cool the turbo down when you shut it off...and you won't have to worry about coking.
