i have a garrett turbo i bought off my buddy. i need help identifying it. .70 a/r compressor housing and a. 84 exhaust housing. i was told a t70. not 100% sure on size been told a couple different sizes. im baffled

 

pull it apart and measure?

 

if i remeber correctly it measured. 84 on coldside also

 

it could be chinese turbo and hard to identity

 

The housing stamps .70 and .84 are the A/R of the housings. They refer to the area/ radius measurement of the housing. For lack of a simple way to put it, it is a ratio that is used to state the area of the interior of a housing.

Is there any other markings on the turbo, perhaps a serial/ id plate on or around the chra (center section between the housing) of the turbo? Perhaps you have a picture of it you can share?

If not, what you need to know to identify it is the measure of the wheels themselves (inducer and exducer of both).



From those measures you can approximate what turbo it is and/ or somewhat determine a relatively accurate range of hp potential/ airflow.

 

20 bucks says its an ebay t70

 

well if thats the case im getting rid of it!!!!!!!!!

 

Just post pics of the overall turbo. I can tell you in about 3 seconds what it is.

 

let me find some

 

 

Yup. Ebay t70.
Some have had really good luck with them. Others have nothing but problems. Its pretty hit or miss.

 

hmmmm well my buddy over paid for it when he bought it.

 

ist a ebay t70 ive got one sitting in a box... and it spool very to late...on a b18b

 

mine spools around 3k-3500. not too hateful

 

mine to..began at 3800 but full boost at 7000..it blew after 12 000km

 

well after hearing all of this ill be getting rid of here soon. cause i can almost guarantee it wont live up to my 6-700 hp goal

 

6-700hp with this turbo what block??

 

Unless you were running really high boost it shouldnt take 3500 to make full boost. You have a leak.
That turbo wont support anywhere near 500hp

 

yea ebay t70, i had one of my old set turbo gsr, actually made decent power 440whp on 17psi on pump gas

 

Yea, going to agree with everyone else, definately looks to be a chinese manufactured 'ebay t70' turbo. Pretty hit or miss.

For your goal I would look to change to something more capable from Garrett, Precision, or Borg Warner.
