ive ridden in a few street ported 12a turbos, one had a s4 turbo with a weber carb and a custom intake. It had roughly 275 horsepower at 14 psi (about 220 RWHP).

One has about 350 (blow through), and the 4th produced 498rwhp at 32 PSI.(Haltech F9)
The 4th one normaly runs about 19PSI = 390 rwhp on
the street.
All of them have been running for over 3 years now in South Florida heat and humidity. 2 of those run 22 PSI every day.
Somebody doesn't know what they are doing with a Turbo Rotary, or is running into some other problem.
The 12A's appear to be more reliable than any 13B for boost, with the exception the S5 and S6 Turbo models.

Oh yeah, if anyone doesnt know about JHB Performance @ www.jhbperformance.com they can resurface aluminum housings and cast iron housings, among other things. They resurface with ceramic coating, which outlasts stock housings and is much cheaper than new housings ($280 per housing).
