Good size turbo? T04B S Trim .60 A/R Comp, 1.00 A/R turbine side

I seen this for auction on eBay, it seems it would be a good size for the car too. I've got a compresor map for it at the bottom:

The compressor housing is a .60 A/R with a S trim compressor wheel. The bearing housing is a simple non watercooled design with a threaded oil inlet. The turbine housing is a 1.00 A/R with a fast spooling reverse threaded 57 trim turbine wheel. The reverse threaded design makes it impossible to spin the compressor wheel loose under heavy boost. The turbine mounting flange is the same size as a T3, making for a simple bolt up replacement for a T3 flanged manifold. This is a tangenial turbine housing that flows 4 to 6 % better than an on-center design. I accept paypal, cashiers checks and money orders .

Nevermind, I just realized that the turbo is almost choking at anything over 12 lbs boost, it (for once) actually seems just a little bit too small

a s-trim compressor is just a tiny bit larger than the stock compressor wheel. A hybrid stock turbo would be a much better choice than this.

Personally, this turbo is too small for my tastes. It doesn't really flow all that much until a PR over 2.

If you are going to bother with such an upgrade, get the T04B60-1...

The efficiency plateau is good all the way up to 70%, and you're welcome to run it higher than that.

The problem?  To hit 250hp on the min 70% efficiency, you need to pump it up to 20psi or so.
