Question about my GT35R

[powersstuntworx]

Hey guys! I am fabricating a rear mount turbo on my 1970 RS Camaro ( LS1) and will be using a GT35R with upgraded compressor wheel ( 67 trim )
Anyhow my question is the turbo has previsions for both oil and water.
Now I did get lucky and came across a used STS oil pump but not sure what to do about the water ports? Do I just block them off are what?
Any advise would be GREAT!!
Oh yeah I will post some pics for you guys hopefully tonight..... I did some things a little different, like instead of exhaust y into one I ran both exhaust into turbo, it's pretty sick! LOL!! I hope it works??

Thanks in advance guys:)

anyone???

I would run water lines. This comes up in a Google search and some say they block off the water and the turbos are still alive. Thing is a water cooled turbo has ball bearings and a more restricted oil flow to the bearings as compared to a journal turbo. They know they have the water to control temps............... when you remove the water I would think that it would affect the turbo life.

Like I said, both opinions abound but I'd keep the water hooked up, not that hard to run water lines back to it.

I don't know if you can remove water lines:
as camcojb said, turbos are normaly cooled by oil, but ball bearing turbos have a much lower oil flow and that is why they are water-cooled. I think the risk is to overheat but I am not a specialist.

I am also building a rear mounted turbo, and I choose a journal bearing turbo in order not to need to add water lines from the front to the rear and again to the front of the car.
You will see that there a already a lot of pipes under the carwith such a setup without needing to add 2 more lines.
I have a precision 6765 turbo

Thanks guys, I had this turbo off my subie this is why I choose to use it, because it was there and I already have way to much invested in car....
What should I pull the line from and do I need a pump for return like I do for the oil return??
I have pics, Sorry but can some one tell me how to post them.
Thanks again guys!!
Much love

Hey guys here are a few pics, will post more. I hope I do this right....

Looks cool....but what happened when the rear end goes up....looks like it would hit the turbo. Maybe its the camera view?

I would run the water tubes if possible but also keep in mind one of the biggest "benefits" of putting the turbo in the rear was that it stayed cooler. You may not need the cooling from the water because it may not get hot enough. With that said, colder intake air creates more power :)

I am entertaining the idea of a rear mount set up as well on my 73 Camaro. Yours is the first I have seen. Sent you a PM.

i had a gt35 on my supra a few years back and i didnt use the coolant lines i just blocked them off and the turbo ran great for the year i owned it then i sold the supra. so i neved had any problems with not running coolant lines

What about putting a small pump and a small heat exchanger in the back. Then it would be a closed water cooled system back there? Just an idea.

YEP!! Had the wires crossed.... Dumb a$$. Anyhow, here's where I'm at now.
(I have an ls1, turbo cam, MSD bar map sensor, started the car last night, car was running 16 A/F at idle. Tried to peddle the throttle motor would not rev? The turbo is a GT35R upgrade compressor wheel (67trim) I do have a heavy spring in blow of valve...... Maybe a charge pipe leak? Im using the Painless engine management. Some advise would be great!!)

Thank in advance
I just copied this from other post

16:1 at idle is a bit lean, so i suspect it leans out even more when you rev it. You'll struggle to get the revs picking up nicely with such a mixture.

If the car runs an airflow meter, then a boost leak could well cause running problems. If it uses MAP sensor then it won't....it will just be down on power.
