Differences in turbos

[Mikelb]

Hey, I finally figured out the difference in the two 50-trims I have.

One was a TC03 From a Saab (900 I b/l). It has an encapsulated carbon seal.

The other turbo is a 50-trim from a Mopar setup.

Here are the measurements on the turbos:
(Both have .42A/R compressor housings. The TC03 has a .63A/R exhaust housing).
(oil cooled: TC03)
Compressor
Ind: 44
Exd: 60

Exhaust
Ind:57.3
Exd:44.93
Wheel height*: 27.35

(Oil/Water cooled: T3)
Compressor
Ind:42.5
Exd:57

Exhaust
Ind:56.96
Exd:48.55
Wheel Height*:27.1

*Exhaust wheel heigh is the reason the exhaust wheel won't sit into the exhaust housing, and why I'm having to swap the shafts too.


Now, I have both housings for the TC03. I only have a compressor housing for the Mopar(unsure of model). I was going to swap the exhaust housings, so that I could run the water cooled turbo. The exhaust wheel on the water cooled turbo won't fit into the exhaust housing.

I want to know what to do... rebuild the TC03, and use it? Find an exhaust housing for the water-cooled and run it? Swap the wheels and run the water cooled(using TC03 wheels)?

Also, anyone have a compressor map for the TC03, or know any specs for it?? (I can post a model # when I get home, for the TC03 only).


Edit: Sorry, my measurements were done with precision calipers, in MM.

Damn, after some searching (thanx for the help guys) I think I've figured it out...

The oil cooled turbo has pretty much all the same specs as this turbo:

This turbo wouldn't support my goals(400hp at least 350whp), nor be efficient on my car,
