Water cooled turbo

[OneLethal87GN]

Turbo2nr, as far as I know it's not a new GT turbo. It is just a TE-63-1 that was ordered with the optional water-cooled housing. It doesn't have a ball bearing center section either. It is a big shaft turbo that I bought off a member of this board about a year ago. I believe the water-cooled option has been available for turbos for a very long time.

Turbo2nr / ijames
the compressure side/ side where MAF goes is 2.355'', that's almost too the fins I could not get completely down to fins.
Exhaust side hole is 2.280''
wastegate hole is .600''

I have never heard of a Small shaft TE/TA with a water cooled center. i checked every web site i could think of, and found no info on this. i'm not saying it does not exist, but They must be very rare. Do you have any idea where it came from? i checked Garrett, Percision, Poston, Limit, and no info.

Turbo2nr, it's made by airesearch, and I was told that airsearch and garret are the same company, I'm starting to get the feeling that i've been had ( again )
wish I knew how to put pictures on here ?

Of course it has Garrett parts. Almost every turbo for the GN begins it's life at the Garrett/AirResearch company. It may work, and be a great turbo. Who Knows? I'd call Garrett, or Percision, or Limit Eng.

The compressor side matches up with a TE/TA60 or 61 or 62 (these all use the same compressor, just progressively bigger turbines). A TE44 has a compressor minor diameter of 2.29" while the TE60 is 2.32" (the major diameters, which you have to take the compressor cover off to measure, are 2.95" and 3", respectively). You got 2.355" or 0.035" over the 60 wheel, which could be you not all the way down on the taper or just the clearance between wheel and housing if you measured the housing. On the turbine side it's a little more confusing. Precision's web site does not list the old TA/TE61 turbos any more, and they list a different turbine wheel for the TE44 and the TA/TE60 while other sources in the past said that these used the same turbines (PTE actually lists a smaller turbine for the TE/TA60 than the TE44). The wheel I expected them to list for the TE60 (the wheel used on the TE44), has a minor diameter of 2.228", which with .052" of clearance matches what you measured. So my conclusion is that you do have a TE60. The wastegate hole probably still needs to be enlarged, though, or you might have boost creep problems.

ijames, I sure hope your right, thanks

Carl, they do not list the TE61 anymore because they renamed it the PT54.

Eric, way back when, even after they came out with the 54 they used to still list the 61, with the difference being they still used the garrett turbine housing on the 61 and the pte housing on the 54. I think it's only been on the website revision-before-last that they dropped it (and the turbine they list for the 54 is one step bigger than the one listed for the 44). The surprising thing, though, is listing the 60 with a smaller turbine than the 44 when for years pte and the other vendors have said that they used the same turbine.

i bought a brand new TE61 from john craig this month. The box said TE61! What do you mean it is not being made? John built it, but the turbine housing says Precision. ? It is bigger in every way than a 44.

The "they" Eric and I were referring to was Precision, and only Precision. I was using their website as a handy list of turbo wheels for each model turbo and they (Precision) don't list the TE61, just the PTE54. Yes, John still makes it, and with the Precision turbine housing it is the same as their PTE54 - a great turbo that I ran for over 3 years.

O.K. I took the compressor side housing off( cold side / MAF side )
Compressor wheel at it's largest dia. measures 3.000''. now the fins are staggered big fin little fin, smallest dia. of big fin is 2.270''
smallest dia. of little fin is 2.290'' does this help anybody narrow this down for me,

Maybe your calipers are off just a bit, but it sounds like it could be either the 60-1 (2.320" x 3.000") or the 60 Trim (2.290" 2.950").

It sounds like it could very well be the TE60 that it is claimed to be.

Take off the exhaust housing and measure the wheel. That will get you even more info.
