I have a 92 civic hatch with a D16Z6 and a garrett T25 turbo. Where should I pull water from and where should I feed it back into so the motor doesn't run any hotter.
Thanxs Chris

 

Your turbo has to have the fittings for it. You can't just hook water up to any turbo. It needs to be designed for it.

The Garrett T-25 does have water fittings.

His question was where to get the coolant from the engine to cool the turbo.

What I did: There are lines from the engine coolant system that go to the throttle body. They run parallel to the lines going to the heater core. I removed these, and used the two nipples left from removing the hoses to run coolant to the turbo.

I don't know what the throttle body coolant is for, probably some emmissions thing. But that coolant is better served cooling the turbo.

I take it he knows that

You can choose pretty much any coolant line and splice into it.

Here's a good example from Homemadeturbo.com, this is where I am planning on splicing into my coolant line for my turbo set up...

Let us know how it turns out! I'm using a Garrett T25 in my set up too

 

you could just leave it off without any problems.

most of the time yes, but sometime the seal doesnt like it too much.

you can tap it off the top coolant hose also, using one of those fitting for coolant temp. sensor

 

Well under my hood gets really ******* hot so i wanna water cool it to so it doesn't get so damn hot. I think i'm going to just pull it off my heater hoses.

Same thing I did - I believe the lines on the throttle body are to prevent the throttle from icing or freezing up on cold days.

 

i took the coolant feed by putting a T brass fitting on one of the T body coolant lines

and the return went to the back nipple at the tube behind the block, close to the water pump

 

I still fail to understand why people would NOT use the coolant ports if they have them.

I mean, without them, your turbo can possibly get so hot as to cause the oil to coke up. (Again, only a belief, not a statement of fact) With the coolant, the turbo will only get as hot as the coolant.

I don't know. Maybe on the really big, high boost turbos the coolant has some negative effect? But personally, on my little T-25, I would rather run coolant than worry about using turbo timers and cool-down cycles.
