those people who use 60-1's and T4's...have you seen their setups? they can flow the air to spool it...if you want to spool a 20G on a stock cam, stock porting, stock valves etc. all i can say is good luck. cause itll be hard to do it, especially with your fuel setup. DSM's are 2.0's, they drop in 660cc injectors, 255lph fuel pump, cams, and headwork and alot more effort into getting it all right. its not just putting some turbo on..it takes time and research...research for your injectors and hp goals, research of compressor maps, etc. but as i said, with as little displacement, and apparently no head work, your going to probably want what i listed, for quick spooling, or for mid range spooling
