hey guys, where would you feed a coolent feed, and return line off the motor to go to a turbo that is oil/watercooled?

 

You could use the heater return line, its colse to the turbo shouldent be to hard to rig up.

What turbo are you gonna swap in thats water cooled?

 

garret ball bearing. i received it in the mail today. but they sent me one with the wrong housing. so i need to take care of that. are all fittings npt on the motor? i was thinking buy the water temp sender or where that line comes out of the head or something
any other tips or info would help

 

I think all the fittings are npt, I really don't think it matters where you tap into the coolent whatever is the easyest place to get to.

 

alright, another question is. water are the thread specs for the stock turbo feed line? where it goes into the top of the oil filter housing??
im gunna have to get a oil line for the garret turbo. and i need to know the stock threads. i know the extra port is 1/8npt. thats where i got the oil from that goes to the second turbo. but the stock feed line location what are the threads?

 

I'll have to go look when it stops snowing ( sometime tomorrow). I would assume its the same size, but you know what they say about assumeing

 

i know its not the same. the threads on the stock feeder are a little bigger and more course i believe. it might be a metric thread?
and why would you need a restricted oil fitting for the garret turbo?
how do you know if it has a built in restrictor? where ya live?
we got 8 inches the last two days

 

I line in MD we just got 26 inches and were suposed to get another 12-16 tonight.

I don't know why you would want a restricted oil fitting

 

yeah me neither.
i mad tho the guy sent me the gt35r turbo with a little .63 housing instead of the 1.06 housing stated. needless to say there will be an angry phone call tommorow

 

Dave....
Garrett does this because of the water cooled center section.Its designed to allow for better spool-up as with the water you do not need as much of a oil bath to help keep it cool.Its also designed to be run without the water cooling as then you leave the water disconnected and you do not use the oil restricter.It will spool a bit slower that way but is designed to be run like that.

I have asked this and still do not understand why you want to put a turbo thats about the same size or smaller on the top of your combo.The GT35 is not a big unit and is smaller than the GT37R's that are built for our trucks,imo you just wasted your money doing this.But,its not my truck or motor so I should just clam up I guess.here is a shot of the old Garrett GT37R Stage 3 that was on my truck for a couple of years.You will be able to see the water cooling lines and how they hook up........Andy

P.S.-In photo 013 you will see the top line of the water cooled center section.It connects to the water OUT line from your heater core.The longer bent line will go from the other side of the charger down to the return into the engine block below the oil filter.The other photo is the shot of the entire installation kit of a Garrett Charger.Also enclosed is the GT37R installation Manual for you.
