I think you can get them both ways, arent they just a 45 compressor wheel in a 42 housing? IIRC the results werent much different than a 42.

Map would be similiar to GT4508 at TurboByGarrett: http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT45/GT4508R-774596-4.htm

The one I tested was BB. Peak power can occur as high as 4800 if you so wish. Expect 45-60PSI boost.

Really tight converters, or high altitude is going to make non-nitrous launching difficult or impossible.
