it isn't legal in the US because it wasn't produced in or for the US. lots of people can get away with it. it depends on where you live and how bad there are about looking at things. sr20's are good built motors and would pass smog i just don't think they would pass visual. also, dpends on where you are. my brother has s15 sr20det in his s14 240 and just got it inspected last month. he passed of course. granted i live in pennsylvania and i really doubt people would notice a difference.

with producing power any car can reach loads of power, but it cost money. the more money you have the more power you can have. most sr's with having stock internals and just tuning can hit 300rwhp pretty easily. i have heard some drag sr20's have hit 700hp, but that isn't streetable i think and most likely is sponsored, which means a lot of money was spent on it. it can be accomplished, but i am sure it would take bunch of money later. really if you are looking for something drag and a lot of power something with more than 2liters would be better. even though it is turbo it still has more limitations than larger displacement cars. good luck with your plans. hope that helped
