Why are not much people run water cooled turbos on ther Hondas? WouldŽnt those run way cooler which is better for our engines?

Arturbo

I run it..

What kind of turbo is that? T04e/T3?

Arturbo

Yes it it...but with a water cooled bearing housing.

ah yes....I think this is the next upgrade IŽll make. Is it a Turbonetic?....and how much is such an water cooled turbo? Do you have some numbers on the intake air temp with a water cooled one compared to a non water cooled.

Arturbo

Christian,
A watercooled bearing housing is not so much to keep the intakes temps low, but to protect your bearings in your turbo so that they will outlast your motor. Its a great investment to make your turbo last...

Is it possible to get a watercooled center section added to a turbo that isn't water cooled? I would like to do this someday, but I don't want to have to buy a whole new turbo.

Arturbo

You dont have to buy a new turbo. You just send your turbo out and it can be changed for I think $150 from majestic turbo. Good upgrade IMO.

yeah, I think last I checked with majestic was about 120-150ish

bigTom

not worth it in my opinion... if u idle ur car before u turn it off... ull be fine... u dont really need the water cooled housing... i know people that have water-cooled turbos that arent either water-cooled! the holes are just there... u dont need it

I heard TD04h's and T25 from eclipses/DSM's are water cooled?..True?..How do you hook it up?..what source?

tegtyper

Are you running engine coolant through it, or is it a separate system with its own air/liquid ??

Also, what is the primary purpose- for less wear on the turbo itself, or for reducing intake charge temps?

I run the DSM T25 and it is water cooled. I tapped the turbo in series with the EACV (after it of course) and the flow is pretty good. Some people use the line that is going to the TB for de-icing purposes, but I left that alone.

it is pretty easy to do and will make the turbo last a long time.

Everyone has their preferences and mine is against water cooling. The reason for this is because the advantages of the cooling are only during the cool down period after you turn off your car. The turbo is oil cooled at speed. The main downside, from my experience anyway, is unless you run SS lines the lines will burst over time from heat.

Pritos

could you take a pic of how you routed the water lines?

I never ran water to my turbo. I understood that as long as I timed long enough, I didn't have to use water. It's work well for me so far. I'm just thinking tha maybe I should.

FuzzyGreen

There should be two big water lines that run from yuor block to the firwall on your car. These lines go to the heater, Cut them, place "T"'s in them and then run the lines to your turbo.

I have water and oil running through my T3/T4. There has never been any ruptured hoses from the water section of it either. And I have had it for over 2 years now. This turbo has lasted me quite sometime. The advantage of having it is the cool down time. I ususally only let my car idle for about 20 seconds when Im about to turn it off. My other friends that have the oil only usually let it run for a minute or so. And yes, its engine coolant running through it.

~80,000 miles between rebuilds.

Water cooling = smaller oil passages.

Keep the oil and the turbine shaft near to the same temperature before shutting the car off and you will be fine.

My max oil temp. (on a road course) was ~225-230F.

-who let his previous car cool down for a few min. before shutting it off.

hmm. this has convinced me to get a water cooled turbo. i now see some obvious advantages.

1. cool down time (i'm cheap, not going to get a turbo timer, but will let car idle 30 secs after running).
2. no need to tap oil pan (which means no welding the tee to the oil pan, no new oil pan gasket, no need for oil pressure/temp gauges, messing with the oil pressure sender, using synthetic oil, etc.)
3. reliability

falcongsr

woah woah woah hold on. water cooling supplements the oil lubrication and cooling. you still need oil dont you!?

Willard

That is a given.

Synthetic oil, oil pressure gauge, and oil temp gauge are required IMO.

Will

cyan1de

do you? i thought the purpose of water cooling was to not use oil. or you can do both? someone clarify this please.

EDIT: i'm meaning oil for the turbo. of course you need oil for the engine

Yes, You still need oil even with water cooled bearing sections.
