My center section on my turbo is set up for water cooling, My Question is do you have to use this function, will it hurt the turbo if you don't run water thru it. I probably will use water, but would like to know what would happen if I don't.

Most turbos come with this from factory now days. All four of my turbos have this for my subaru wrx. Mitsubishi, and Garrett GT turbos have this. Helps out in many ways! Keeps oil temp down after engine shutoff, keeps compressor housing/wheel cooler. If you choose not to use this feature, I would fill the coolant area with something like block filler or oil, and seal off the lower outlet.(just an idea?) How about using the coolant lines that go to throttle body? Just run them to turbo. You do not have a TE-60, I'm sure of that! Sounds like a garrett GT center, ball bearing! Nice turbo! Takes a beating. Does it spin well with a snap of the fingers? My Garrett GTs will spin for about 1min. After I shut off car.

Turbo2nr, thanks for the reply, what makes you think it's not a TE60, surely there must be some way to I.D. this turbo

Te/Ta=no water cooled center section. I have a TE-61, My friend has a TE-60, WWII era turbo technology. Your turbo sounds like a modern Garrett GT series. Very different! How much did you pay? Did you not read my other post?

I bought this turbo from a member on this board, it is new, never been installed, he sold it to me as a TE-60, price was right I thought, So thats the only info I have. I have not installed it yet, I was just trying to get some info on it before I put it on my car.
 
You can take off the compressor, and turbine housings, and measure the wheels. Then call John Craig, or Garrett, Or percision.
 
If it isn't a true ball bearing turbo then most likely you won't need the water cooling.

I'd find out what it really is first then proceed. :)
 
Well I've made up my mind to go ahead a run coolant lines, But I still would like to know for certain what the turbo really is with out dismantleing it,?

I have a TE-63-1 and it has the water-cooled center section. It is an option and the 60 could have been ordered with this option.
 
That's good to know, All I know, it's not a stocker, and the seller said he thought ? it was a TE 60, I'm just gonna put it on and see what happens, Hope it puts me in the low 11's.

The way to be absolutely positive is to take off the covers and measure the major and minor diameters of the wheels. However, you should be able to get an answer with just the minor diameters. Measure the inner diameter of the turbine outlet hole, and if you can get a compass or pair of dividers try to measure the ID of the compressor inlet even with the top of the blades. Try to get within 1/16" if you can (measure each hole 3 times and average), and subtract about 1/16" from each reading to allow for the clearance between wheel and hole. Then go to precision's website since they now list the diameters of the wheels they use, and try to match up what you have with what they sell. Then post the numbers and we'll all guess along with you :-).

Is that a GT center section? Ball bearings? If not, I just learned something new.
Never heard of a TE or a TA with water cooled center. where did it come from?

Scott

Is that a small or big shaft turbo?
 
First off let me be clear, I don't know sqwat about turbo's,
How do you tell what your center section is ? On one side it shows a clock with a line going 12 O'clock to 6 O'clock, it has a Y stamped in it, the other side shows a 4 and a 1 stamped in it,
it's a 3 bolt with a very small hole where the puck would go,it also says M3 airesearch on the exhaust side, and nothing on the compresser side, ,How do you tell if it's a big shaft or not ? just by looking I would guess it is a small shaft. Again I bought it from a guy who bought it from another guy etc.etc. who said it was a TE 60, The guy I bought it from said it would be to big for his combo , and he wanted a smaller turbo.

P.S. intake side measures 3 inches O.D.
Exhaust side measures 2 1/4, puck hole is 5/8 inches,
Vern
 
that wastegate hole sounds way too small! Mine is 1"
when you say exaust is 2 1/4, you mean the compressor outlet? Right? I think this is a Turbo for a 4cylinder engine, like a WRX, or a Neon, or a Lancer Evo. All of these cars run a water cooled center, and the smaller wastegate hole.

scott

why don't you just call a turbo dealer? Percision, John Craig@ Limit, Or even Garrett. Then you will know for sure! Let us know.
 
Vern, the 3" sounds like the outside diameter of the compressor inlet, where the maf hose slips on. You need to measure the inside diameter of the compressor inlet, down at the bottom of the taper, right where the compressor wheel fins start. You have to reach in with something like a compass or dividers, with two sharp points, adjust them out so they just touch the inside of the housing, then carefully pull them out and measure the distance between the tips. The stock wastegate hole was about .75", I think, and for stock elbows it is usually opened up to about .9". The puck in a THDP is much bigger, and the hole can be opened up to about 1.25" (I'm a little hazy on these three numbers so don't go drilling based on them :-)). And just to be sure, the 2.25" was the turbine outlet, right next to the wastegate hole, and not the compressor outlet, right? I'll try to see if that matches up to one of the standard turbine wheels.
