I've read your posts and it seems you have successfully gone pretty far with the N20, I say go for it!
I just want to throw my 2 cents out there to you and others, keep in mind that turbo changes aren't always for huge horsepower and torque - they can also move the curve with great results rather than simply adding to it.
Take a look at their N55 stage 1
here. Check out the dyno chart, and reference the N20 JB4 dynos to see what I'm talking about. The N20 is engineered for good balance of efficiency and performance, and the turbo plays a key role. Changing it to something that flows better at high revs can move the torque and power peaks higher and/or flatten their curves, where the factory N20 will taper down (because it's optimized to lower revs which is a tradeoff of peak performance). Without getting too deep in the HP vs. TQ discussion, I'd just point out that moving the torque higher up in the revs results in greater power even at the same amount of torque and boost as JB4, for example, if you can follow that explanation.
That being said, Pure should probably consider taking on some of the liability that they are asking for from a development car, with the rod incidents we've seen from turning up boost.
