How many of you run watercooling to your turbo? Wondering if I should. And what water line to run to it. S13 sr20de+t blacktop

Literally everyone with a garrett or other mfr ball-bearing turbo does. That's how the turbo is designed.

>Some generic info on Garrett's site about water cooling<

Short answer; what turbo are you running? Does it have water ports? If it does I would be damn sure it was plumbed up before I ran it. If not (like 99% of all journal bearing turbos) then it is designed to be cooled by oil.

Don't reinvent the wheel here man.

Water line in to turbo from outlet manifold, water line out from turbo to header tank on mine.

If the turbo has water ports on the center, then use them. Simple

On sr20 ive used the stock spot on the block(dont rember thread pitch) to an fitting. And either tap the upper water neck, or buy an s14 one. Those spots work perfect for coolant feed and return

Might buy a s14 water neck for return. Where abouts on the block is the feed. And if I dont end up getting a s14 water neck where else can you return it to?

Also random question. If I put a water temp sensor in the upper rad pipe will the reading not be accurate because of the water coming from the turbo? If you get me

Not tryna reinvent the wheel mate just wondering where to run your feed and return lines since it's a de. I'm running a gt2876r bb turbo btw. But alot of people in nz dont bother running water for track cars. Which I should probably add. My cars a drift car and drift car only. Wont see the street

its not required but will greatly extend the life of the turbo...if i were doing it myself and trying to keep it simple i would split the heater hoses and put a t fitting to and from the turbo coolant areas...not necessarily the best spot but an option...

If anything i'd rather have water cooling the turbo on the track/drift car where it's going to get more abuse and heat vs. a street car. Your thought process is backwards here.

I don't have a thought process haha. my thought process is look at all the other cars and see they don't run water. So figured maybe its better for street driving since water from what I know mainly benefits on cooldown. and for daily driving turbos most likely wont get time to cooldown but on track cars I don't mind letting it idle for a minute. idk though im in NZ so most people don't give a sh*t anyway so its not a easy read of what to do haha

"The Garrett engineers are asked many such questions regarding our water-cooled turbochargers. Many customers question the necessity or benefits of plumbing in those extra water lines to the sides of the turbo’s center housing. Why not just leave them off? The reality is that a water-cooled turbo can be damaged irreparably without proper water line setup. With a little background and some explanation of what water cooling really does for turbochargers, this Garrett white paper will hopefully convince a skeptic that the benefits provided by water-cooling are worth the small effort required to properly set it up."

Straight from the link in my first post. From the people who make your turbo. Or get a journal bearing turbo that doesnt need water cooling. There are a plethora of options in a t25 footprint. It'd be cheaper to just run the coolant lines to your existing turbo though.

Sweet I'll get them hooked up. Sounds like theres a hole in the block for water in and I'll probably get a water neck which it can go back into

Kingtal0n

you absolutely need the water for turbos that take water
