I know it's not alot to go on, but I wanted an educated guess. Does anyone recognize it by looks alone? I know the new gt3076r's have a different compressor shroud, but I had thought the older models had this style housing. It does look similar to the gt3071r as well.

I was told it is a gt3076r, I'm not sure on the a/r, but was hoping it's an .82 housing.

Hopefully going to go take a look tomorrow or Thursday to see what it is in person, measure if need be.

Curious what others think.

Thanks.

easiest way is to mic the compressor wheel and turbine and wheel and go to garretts site and look at the turbos on the list. is it a bb for sure? You can tell by wiggling the shaft they just have that mechanical feel.

 

Looks like a Precision turbo, well at least the compressor housing since thats all we can see. If it is actually a precision unit, look on the outside of the compressor housing outlet around the edge, they will have engraved/ scribed in their model number. If you dont see anything, as said above best way to know what it is, take off the housing and measure the inducer/ exducer with digital caliper.

You should be able to tell if it is truely a BB unit for starters by looking at the center section, which should have both oil and water cooling ports.

Also as for the a/r of the housings... should be stamped on or in them, alot of times exhaust housing are stamped .63, .82, etc on the outside but they can also be stamped just inside of the flange were it meets the manifold. Compressor housing could be stamped externally as well but also it could be stamped just inside the outlet.

 

yeah but not all ball bearing turbos were water cooled. Majority are though.

 

I am going to try and pick it up this afternoon evening, maybe even tomorrow and see whats up with it.

Thanks for the help.

 

what does it say in that red box?

looks like the engraving that twkd was talking about. try to get any numbers or marking, a pic of the comp hosuing doesnt help us at all. and of course the only way to be positive is to measure the wheels

 

Totally cold guess...


SC6152/76E???

DEFINATELY NOT a 30R.



EDIT... Just zoomed in on the engraving... Indeed it APPPEARS to say 3076, but I dont see a "R" denoting DBB... huh, WHO KNEW...

 

i thought i saw a 76 in there too but its hard to tell

 

jeff at evan's tuning had listed a car that had a precision gt3076e and he said it was the same and was ball bearing just with a e compressor housing and was relisted at precision

 

Looks like a Precision turbo. This is what I can read from that pic "GT3076RL". The "GT" the "76" and the "R" I can see clearly, the 30 and L not so clearly. I'm going to guess its says GT3076RLS.

But deffinately take a mic. with you, measure the wheels and compare to the specs of a GT3076R

 

DEFINATELY not an S... S is the S cover... 4 inch inlet/2.5 out....

 

I have the turbo in my hands, my buddy let me bring it home to look it over.

Here is what I have so far.

Info so far.

Compressor side etching
GT3076RLE

Also stamped on compressor side A/R 60

Metal tag on center cartridge
FF 0121J
700177-13

Nothing other than Precision cast into the turbine side.

I really need to know what a/r this is, .63, .83, or 1.06

Btw, it has a 5bolt exhaust flange

Lookin for some help, thanks again guys.

 

Oh wow, the old 700177-13 60 trim GT3076Rs. See, the GT3076Rs came in 52 trim (the same trim as the the original GT3037 w/ its 76mm compressor exducer), 56 trim (the standard GT3076R that people here know with its 76.2mm compressor wheel exducer) and the coveted 60 trim. The efficiency of the 60 trim was a bit less efficient than the 56 trim, so that is why it is not as utilized. only Precision still uses it for some reason. (there is another thread from Muckman devoted to the difference b/w the 3 types, so please search for that instead of refilling this thread up with the debate).

They came in either .63 .82 or 1.06 A/R housings using the same 84 trim exhaust wheel, so only the OP can answer that question by looking at the back of the turbine housing itself. If it is a 5 bolt exhaust flange, chances are it is a .63 or .82A/R, and not the 1.06. These GT3076RLEs came only in an S cover, or Precision's own "E" or "S" cover. You'll get the same power as the standard GT3076R that we all know, with the exception that the powerband will be a bit higher in the rpm range. It will shift about 500rpms or so.

 

post up some pics of the turbine side
