The factory 2.1 RSR engine was all mag. My 2.3L turbo project is all mag, too, and uses a 2.4L 7R mag case for strength, plus shuffle pins and case savers. I would not exceed the smaller bore for a turbo on a mag case. My research leads me to have no concerns on this motor which will make well above 300 RWHP at 8.5:1 CR, around 1.5 BAR...static CR w/ cams makes it peachy. And yes, I am using sequential EFI, twin plugs, ITBs, knock control and methanol inejction with a water/air IC to get there.
