For anyone that's looking.

The NA SRs are not nearly as expensive as SR20DETs, so the price of this swap should be significantly cheaper then a regular SR20DET swap. HOWEVER, for those that have questions as in regards to how much power this motor can hold, etc.......They are comparable to your SR20DET. I am currently running a NA in my sil80 and the motor has made 413rwhp on 93 pump gas with 21lbs of boost.
