Im not 100% sure what size it is... here is a picture

 

purdy

 

What do the numbers say on the turbine housing at the bottom by the flange? Give m to me and I can tell you then.

 

look at the inside pathg of the turbine inlet, it should be stamped on there...

for the compressor, take out the compressor housing and measure the smaller of the wheel diameter( upper part) and measure the diameter of the major wheel ( the bottom part) and post the number..I'll tell you what you have

stan

 

On the turbine housing near the flange it reads

Compressor side - "20358"
Exhaust side- "0357"

 

Turbine side I show as a .63 A/R T3 housing, are you sure you don't have the #'s mixed between the compresssor and turbine. I'm looking theorugh the whole catalogue for you, 20358 is a .63 A/R turbine housing part #. The 0357 seems to be incomplete!? Is it 20357 or 30357? 20357 is still a turbine housing though. ?

 

Look at the turbine side where the actual downpipe mates to should be a set of numbers there as well, I remember mine had it and showed there I had a Stage V wheel stamped on it.

 

Thanks for looking this up for me, i really appreciate it. On the exhaust side i just see "0357", i just went out to my garage and did a double check. It looks like there might have been a number in front of it, but i cant see anything but the 0357. This turbo is supposedly rated at 400-450hp. If you can, look up the 20357 and 30357s, hopefully we can figure this out without me having to take it apart.

 

I think I have the same turbine housing. My turbine says 20358 on the side near the compressor, and it says 20357 on the discharge side.
Here's the view from the compressor side"

So how do you tell if it's a .48 or a .63 a/r housing if the p/n's for both are on the same housing?

 

Where at again? hehe

Mine has a set of numbers on the flange side but also where the downpipe mates to the dischcrage right next to the hole for an internal wastgate, my set says 20359-03 which is a .82 A/R turbine housing with a Stage 3 wheel but it has the -03crossed out then below shows it is actually a Stage V , I hopeI'm not confusing you now. ;( mINE IS AN .82 A/R w/ a Stage 5 turbine wheel. On the compressor side mine says 20190 whis is a 60-1 compressor wheel within a .70 A/R housing with a 4"inlet. Yours is a Tubronetics right?

 

What did you specify, a .63 A/R is a decent size a .48 A/R is pretty small, I was about to say you have a .63 A/R because that what shows but tnen your discharge has something different which says it is a .48 a/R, mine is opposite has the .82 A/R part # on the discharge and it is definatelt bigger than a .63 A/R!

 

Yes, it is turbonetics. Before i knew about compressor trims and AR's, i just told my buddy at drag to supply me with a turbo that can handle up to 450hp, so i would assume he gave me a 63 and not a 48. I read in a thread that the 48s usually fall on their face at about 250-275 hp, however this turbo is pushing out 330whp at 14psi on my application currently...

 

AHA! Mine has a 20358 on the compressor side on the actual flange as well, But my specific turbo I ordered is the .82 Aa/R and this is what is on the discharge by the wastegatte hole, I had to take my downpipe off to check this, so I'm working for you guys here. I would sugest looking at the discharge hole and check for the #'s there. I wish I still had my old tiny turbo to double check everything.

 

Damn, I guess I'll have to remember to check the next time I have my dp off. It's kind of a bitch getting to the bolt in the back without taking the entire manifold/turbo off the car.

 

The number is stamped in the inside of the turbine flange look into the mouth.

 

.82....
ahahaa..im not really sure what it is

 

Compressor side - "20358"
Exhaust side- "0357"


Bump
Im selling this turbo and i need the correct information, i still am not sure if it is a .48ar or .63ar.... I looked all over the turbo for more numbers and i cant find anything!

 

20357 is the pn# for a .48 a/r housing
20358 is the pn# for a .63 a/r housing
20359 is the pn# for a .82 a/r housing

hope this helps.

 

so what does the "Compressor side - "20358"" mean? Hurry up so i can order that t4 60-1 .70ar ptrim from you! hehe thanks for the help

 

20358 is the pn# for the turbine housing, that is cast on the inlet..

 

So what does it mean when my turbine says 20358 on one side, and 20357 on the other?

 

Well WTF then? Mine says 20357 on one side and 0358 on the other. It also has the 60-1 compressor wheel. By these pn# it should be a .48 a/r. But on the inside of the turbine inlet there is a 63 stamp.

Please let me know.
Thanks,
Ryan
