Martin, there are some nice shots there. Makes me miss SoCal!
I think you're going to see a drastic deference between the 16G and DSM76. I know you're expecting this to some degree, but from your comments, you may want to reconsider that turbo choice if your end goal is a fun street car that takes a good flogging on a back mountain road.
If you're planning to stick with a pump gas tune (not E85) I'd definitely reconsider the DSM76. Keep in mind also, you're going to be ~30 psi before that turbo is in its efficiency range. And, between 0 and 30 psi, you're gonna get a whole lot of lag on that 2.0L, especially in comparison to the insta-spool you're used to on your 16G.
I've seen multiple conversations on Tuners where people were considering this turbo for road racing, but decided against it in favor of the faster spooling FP3052 and even the FP3065. In short, just consider your end goals for the car, and make sure the DSM76 fits them. There are a lot of turbo options that would net you more airflow (than the 16g) without completely sacrificing low end response, all of which could be funded with the kind of change that DSM76 setup would fetch.
Great build overall, looking forward to more updates.
