Ok, so lets say i'm not going to run water to the turbo,
just oil.

I want to remove the turbos metal water lines,
mainly because they're fugly, and they jet out all crazy out of the turbo.

Now is this ok? It leaves behind a hole in the center section of the turbo, on each end.

is it cool to just leave that hole there,
or do I have to plug it?

thanks

that turbo was built w/ water lines for a reason!!!!
use them.... ur turbo will last longer if u take the time and do it right!

Yes, and a Honda was built to run on 85 octane ****-water naturally aspirated.

Many people go without the water lines when putting water-cooled turbos on Hondas because of Idling issues. Because Hondas use the coolant temp sensor (along with others) to establish idle speed, running coolant lines tends to give ------- idles (lopey, especially while cold). Another problem with watercooled turbos are that they tend to make coolant temps fluctuate (i.e temp gauge fluctuates - goes up and down - while driving). Also, in most cases the car takes a longer time to reach normal operating temps - especially in colder climates.

Most companies water-cool their turbos because they expect the average buyer to go 100,000+ on the original unit, however, you can be sure that your non-watercooled turbo will outlast your stock motor or the time you own your car (assuming the turbo is in good shape to start with).

ummmmmmm ok......

i got a question.... what temp does oil "COOK" at?

and what temp does the turbo housing see?

and, if the turbo is seeing XXX temp why would it take longer for the coolant temps to raise if it's circulating?



ur vast info is irrevelent here!!!!

we've allready had this convo in another post!!!!!!!

hmmmm.... to answer your question, standard oil starts to break down at 250-300 degrees while synthetics last up to 450 degrees... most turbo housings will see between 300 degrees at idle and 1300-1500 at wot (wide open throttle)... now, the average n/a honda combustion chamber temps range from 900 to 1800 degrees while high horsepower engines sometimes hit close to 3000 degrees. If oil can lubricate while surrounding temps are close to 3000 degrees, I don't think 800-1200 degree temps (average driving egt's) will be much of a problem. A problem does however arrise when the oil sits in a 1200-1300 degree shaft housing and does not go anywhere. This will make the oil solidify/coke (over time) and cause damage. This is where propper cool down proceders (idling the car for a minute after hard driving) and a good oil drain setup come into play. Car manufacturers know that a good amount of the time, people are not going to sit in their car everytime they drive aggressively and let the car cool down before turning the motor off (even though every turbo car manual clearly states too). This is the main reason for the water jacket around the turbo - to *help* pretect women and dumb-asses. I don't know if you know it or not, but a majority of aftermarket turbos are **OIL-COOLED ONLY**. I'm sure these manufacturers are aware of "what temp oil cooks at" ....

To sum it up, water cooling is not necessary if:

1. You can fabricate a propper oil drain system.
2. You are not retarded and/or frequently late to work school and can not allow your car to cool down and also cannot afford a turbo timer.

crx304:
I appreciate your input man,
but sorry used2baracer is correct, and I am not going to use the water lines. The previous owner of this turbo attempted to use the water lines, on a very similar motor, and had overheating problems.

And I've read previous posts of people asking if they should run water lines, the ressounding reply was that they are not neccessary as long as you have proper oil flowing, and you turbo time it.

Now my question was about the water line fittings..
and 4 posts later it hasnt been covered, and might not.
So I ask anyone reading to refer to my first post and plz try and answer.

thanks.

I would personally leave it open unless you can find a stainless/steel plug, in which case I would only plug the side you can see. DO NOT USE A BRASS PLUG, as the melting point of brass is around 1600 degrees and although the turbo probably won't get hotter than 1300-1400 degrees, that's a little too close for me.

I've been using my 14b water cooled for almost a year with no overheating, no problems, and no serious idle issues.

I originally intended to water-cool my 14b, but never got around to it. I have had it un-plugged all this time and it's no big deal. I might get a little dirty in there, but it doesn't affect anything. So plug it if you want, don't if you don't.

what do you mean "no Serious" Idle issues?
