compressor housing question? t3 super 60
 

So I received my "t3 super 60" in the mail yesterday from blaast performance. I still have the other t3 that I bought sitting around (0.60 compressor / 0.63 turbine garrett t3) so I compared the two.

The compressor housing on the t3 super 60 is from an 84 nissan 300zx (it says Nissan on it, 300zx came with t3 from 84-87, 84 was oil cooled only) and it looks really small (as far as internal volume) compared to the 0.60 a/r garrett t3 compressor that is on the other turbo.

Here are the two turbos side by side t3 super 60 on left

Here is the garrett t3 0.60 a.r compressor from some ford (svo or t-bird)

My question is this, these compressors are supposed to be the same i.e. garrett 0.60 a/r t3's but the nissan compressor looks smaller. It's hard to tell from the pics but it is a lot smaller, it seems the internal volume of the nissan compressor is much less than the ford one. Will both compressors flow the same (since they are supposed to be the same). Should I be worrying about this? Did I get what a paid for (t3 super 60)?

Any input would be great.

pull the compressor housings and measure the inducer and exducer of each and you can tell exactly what size wheel they are. Otherwise the A/R means absolutely nothing (as far as determining trim size). To me the Nissan one on the left looks like a Super 60.

All T3s have the same exducer measurement, 2.367", it's the inducer size that really determines the trim size of the wheel.

I'm more worried about the size of the compressor housing, the trim of the wheel looks right. The Nissan compressor housing looks small compared to the ford one, does this have any real affect on performance?

Do the two have the same internal volume (compressor housing volume that is) and the castings just look different on the outside?

whats the A/R on the nissan housing?

Not sure, I didn't see it stamped on it anywhere and all the info I can find on 300zx t3's don't mention a/r's.

*EDIT; I did some more researching and everything I've read says the nissan 300zx t3 compressor has a 0.60 a/r.

It's really rather hard to tell from the external casting as to what casting will flow what lbs/min and the A/R for that casting. Assuming that they are both .60 A/R castings and that the inducers are nearly the same size, they will flow the same or close enough. In the real world the T-Bird T3 flows as well as the S60 for the most part, mainly due to the same size exducer and A/R housing for the compressor. It's a pretty trivial difference.

300 ZXs have the same .60 A/R FWIW.

Oops, saw your edit already. Nevermind.
