water cooled

[far1002]

i bought a turbo that was not sapose to be water cooled and it is will it hurt the turbo if i don't run water to it

[ftrs13]

just make sure to let it cool down, from what I hear, and practice, is that the oil jacket is still the same size, water just runs over the outside of it. I have a watercooled turbo and havent hooked up the water yet. soon I will, and you should too, its just an amazing feature that basically doesnt let the turbo get into the coking temp range

[WAbernethy]

It still amazes me that anyone would take the time to set up a turbo and then not hook up the water lines. It's not hard to do and it's not expensive. As a matter of fact, you can bypass the coolant going to the intake manifold and use it to cool your turbo, kill two birds with one stone so to speak. Just my .02 but I'd hook it up.

I know that, but living in the slightly frigid climate of NH I need the manifold coolant to unfreeze my throttle body every now and again, and ive been running for 300 miles, nothing huge. I had to rush to complete the turbo as it is ... I left for school 2 hours after finishing and driving home, I just got back for the summer, and will hook it up shortly.

i put i bypased the throttle body warmer and it seems to be workin fine all it really cost me was the hose 5$ . thanks

Can someone show a pic of how to bypass those TB warmer lines? on an SOHC if possible, but a DOHC explanation would do too, and maybe a reference on how it may work for SOHC.

This is sort of one of the few things left unclear to me: where to get the water cooling feed and where to return the water.

If people have different ways of doing it please feel free to show them, I'm sure it would be most appreciated by everyone (who doesn't have theirs set up yet ).

I'm in the same boat, right now I'm rushing to get the project finished. Once I do and get it running and have a few extra dollars or minutes to spend on something else, I'm going to water cool them. But my turbos didn't come with the water fittings, so its going to cost me more than just a hose.

[sil80drifter]

soooo... anyone? suggestions? pics?

oh come on, nobody can post about hooking up the water lines to a turbo? nobody has pics? everyone is lazy? grrr.

I will try.

On the E, there should be a 3/8" or so line coming from above and a little back of the oil filter. I'm pretty sure it feeds up between the intake runners to a nipple on the top section of the intake. That should be the feed line coming from the block to the turbo. The other line T's right off where the radiator top hose comes out of the engine. It loops up to under the TPS. That will be your return hose.

That's about as good as I can remember the layout. Go check it out on yours and let me know if it makes any sense.

[sil80drifter]

Well, now that I have turboed my car, what I did was to take the coolant that comes OUT of the throttle body, guide it to turbo, and what comes out of the turbo goes back where the TB hose use to go. So I am cooling the turbo down, and the throttle body stays warm (not bypassing it in other words).

I've heard some bad things about water cooled turbos... I forget where it was but I remember reading some horror story about how it heated up the coolant so much that it started to evaporate, and eventually either starved the engine of coolant, or supplied it with superheated turbo coolant...

Just run a whole new pump with a cooler... Would not be that hard.

My water cooled T25 on my SR is doing just dandy - no coolant boiling from here.

I personally would not run a watercooled turbo without water though. the center housing isn't designed the same as a non-watercooled turbo, so you do run the risk of things cracking if you run it really hard.

My T3/T4 watercooled turbo sends my coolant temp into orbit. I have a fairly large Griffin "Scirocco style" radiator on my KADET and it can't get the cooling job done. I plumbed it by putting the turbo waterjacket "in line" with the TB preheater and it works fine except for sending my coolent temp to over 220 at idle.

What kind of fan do you have on your radiator? I have dual 12" Flex-a-Lites and they bring my temps down easily on a Koyo rad.

[sil80drifter]

If it's not stop and go traffic in 95 degree weather, I don't even need to turn on the fan on my radiator.

Granted, it's a Ford Racing radiator I've gotten off of e-bay, and is the biggest one you could fit into an S13, BUT it is aluminum, very nice, and has a huge capacity. And only 250 bucks shipped.

I believe I am the first one to ever use it for the s13 application. Had to trim the battery tray a bit, sicne it was protruding into the radiator area, but I relocated my battery into the trunk a while ago anyway.

If one has a water cooler turbo, is there a need for a turbo timer?

In other words, does a water cooler turbo replace the turbo timer?
