Just to Add to that I think a rotated GTX30 tuned properly is by far the best turbo for a 2.0/2.1 not only will it be responsive as hell but on a GC8 you'll probably be quicker than mine. So you'll have the driveability and the power. That's a win win in my book.
The GT35 will be a pig on the road. It'll be nothing, nothing nothing, everything, run out of revs, change gear and repeat. You have been warned
