i need some advise or at least a compressor map

[Nissan_Convert]

this summer, my best friend and i have planned on swapping his 98 240sx with our newly acquired s14 s20det and modding it (duh). The goal for our project is 300rwhp. I want the car to have streetable power though, turbo lag is not an option (or very very small option). My question for you SR pros is this: will a stock s14 sr20det ball bearing turbo happily make this power or will it be near the end of it's effeciency range or will it even get us to 300 rwhp? I wanted to go with the gt28r (the disco potato sentra turbo if you aren't sure) or another rendition of a t28 bb turbo but if the stock turbo will get us to our goal why not save some money. Does anybody out there have a compressor map for the stock s14 turbo (i've searched) or any technical information? I'm far from a noob, i've been into the turbo honda scene for a while now so hit me with all the information you have.
