I got this turbo that is supposed to be a T3. It has a VW and Audi symbols on the tag. Here are the part numbers from the tag.

VW part # 075 145 703
Garrett #466088-1

It has a 4-bolt downpipe pattern.

What size is this turbo? How can I tell if it is just oil cooled or water/oil?

Thanks!

 

post up some pics and let us point it out to you.

 

Ok I have taken some pics but I can't figure out how to attach them to this posting (help). Taking these pics brought up some additional questions. How do I remove the internal wastegate because I intend to use an external? What are the two brass connectors for on the intake housing?

Thanks!

 

I beleive all 'newer' VW and Audi turbos are water and oil cooled.

 

The downpipe is a 4bolt.
Is it a square pattern?
Is the header flange a rectangle 4bolt.

What's the # stamp on the Exhaust housing toward the bottom. Should be an M followed by 2 numbers...
Example M26 that's .63 exhaust stage 1

For the oil/water cooling
Top of turbo single threaded flange female is oil feed
Gravity dropped 2 bolts around a squarish hole oil return
Any seperate lines prob off right front corner and bottom left are coolant feeds/returns.

 

I'll answer those questions when I get home. If someone could tell me how to post pics I think it would help?

I posted links because all I could see was red X's

 

Yes, downpipe is a 4 bolt square pattern.
Yes, header flange is a rectangle 4 bolt.

It's hard to make out the letters on the exhaust housing but it looks like it says "M4 26L4"

Also what are the copper 'tubes/connectors' that are on the intake housing? One is on the 'ring' of the housing and one goes into the hole where the intake pipe connects.

Thanks!
