He should put an entire TS setup on the 2.3L and see what he gets.

Don't like the comparison at all if I'm comparing both turbo setups. Too many variables.

Yes, I don't think he really was doing this to compare the 2 turbine housings though. I think he just wanted to show the range of possibilities with this turbo.
The 2 liter with .55a/r housing, 22psi, 93 octane no meth, that is the one I really like.
When you compare this at different rpm points to a 50 trim under similar conditions, the S256 looks pretty good. I know, you can find a wide range of 50 trim dyno results, but here's a pretty good one that I like to use for comparison purposes:
Automoto Sports Copyright&copy AMS 2006
At the bottom of this page, one of the dyno charts is for a 2 liter with the good AMS bolt-ons, with 50 trim tested at 21psi 93 oct, and 27 psi 104 octane.
Pure-Tuning's results at 22psi 93 oct look quite a bit better than the AMS 50 at 21 psi 93 oct, and almost as good as the AMS 50 at 27 psi 104 oct. The AMS was on a Dynojet besides, so I'm thinking the .55 a/r S256 looks mighty good compared to the ball bearing 50 trim Garrett.
