Title: another "what turbo is this"
Post by: 1outof5 on October 18, 2009, 07:07:02 am
I've been given this newly rebuilt turbo, it's a Garrett (writen on the housing) but that's all I know.
The usual green tag is no longer there an in it's place there's a piece of sheet metal with a "serial" number that's partly visible (looks like it was hand engraved). Can any one tell what it is? The information from the gift bearer is that it came out of a passat AAZ but I have my doubts as I thought that the AAZ only came with a K14. Is this a T2?

thats a trapezoid T3 flange on there it looks like. its a T3 tho for sure. the junk one i used to have looked just like that. looks like its just a stock 1.6 turbo.

Itīs not, T3, T2 it is.

wheres the T2 flange? and the water cooling? thats the oil feed line you see in the picture.

What T2 flange? All 1,6 turbos and 1,9 K14&T2 share same flanges. AAZ T2 is not water cooled. Here is 1,6 T3 (http://www.kotinet.com/matti.farm/Audi/Moottori/114-1492_img.jpg), donīt mind vnt20 on right.

It's not a stock 1.6 T3. Center section looks different, and it has a different wastegate actuator.

T2

so T2 then!

what are the differences between a "standard" T2 and a watercooled T2? (yes I know the watercooled T2 is watercooled  ;D)
What would be better for a 1.6 TD front mounted IC, Giled pump, 15/18psi ? Its for my daily driven caddy.

If the watercooled T2 is a better option are the parts interchangeable, like taking the parts of the H2O T2 and putting them on the "standard" T2 (as it has just been rebuilt so like new)?

I wouldn't mess with it, too small.  18psi would be out of it's efficiency range for sure.

I have this same turbo set up with a Giles pump and a Saab intercooler.   You didn't say what vehicle you were going to install it on???  I have this setup on a Vanagon Syncro with a high top.  I have been told that the T2 is very similar to a K14; performance-wise.  As Andrew pointed out, it spools quickly which is really great for altitude and in my case- the mountains of CO.  I have mine setup for 17psi of boost right now.  The only drawback; I am fairly convinced that using such a small turbo helps heat up my oil much faster than if I were to use something like a K03.

What are the boost charasteristics of that setup? Boost vs rpm & boost on the highway cruising? My understanding is the T2 is good & happy at 20psi. Maybe pushing its efficiency there but as Andrew said above, nice & driveable.

I am in the process of sorting out my tachometer so I can't answer the first question.  I would say that for hwy cruising, I am between 5-10psi and only get above 14psi when I am climbing a long grade.  I know of another person that ran the T2 on a Syncro Westy at 20psi with good results.

I'm sure it does heat up the oil more than a more efficient turbo would, but the K03 would be similar.  You'd have to go with a k24 or T3 which in a vanagon at altitude have unbearable lag.  Those are all the reasons that I'm happy to deal with the added complications of VNT turbos.

Is there a reason that you have not tried a GT series turbo from Garrett?  They seem to have fast spooling, ball bearings (that are both oil and water cooled), and have plenty of power.
