The intake sides are really close...but the exhaust is the difference! The GT42 has a smaller wheel, ans is available with a choice of housings down to 1.01A/R. Really good spoolup, but you'll need to wastegate the bottom charger as well as the top one to control boost and keep drive pressure down!
BTW, there are two different GT42's...GT4294 and GT4202. The 4202 is what you want, it the 75mm version like the S400/B2!
