small turbo is definately way to go if your hitting some twisties and want peak power for the lower rpm's... but K03 we speak of is a vw/audi thing... your not going to get that on your car... one turbo i have seen similiar to size i think was the stock vr4 turbo (i think that was it) 220whp/285lbs @ 3500 makes a fun little car to toss in the mnt's \/
