Whats the best swap for a EG9 4 door?

hi, ok so i curently have a B16a in the car rite now but the rings are going and a whole bunch of other stuff needs replacing, so it'll jus be easier and CHEAPER to buy another engine : i jus want to know whats the best bang for my dollars "which isn't allot BTW"...not into drag racing jus sumthing quick and responsive for auto cross
im sorta planning to jus buy a B16a head and block and build another B16 but it's like been there done that to me..or should i go ahead and do that?
another question: will a LS/vtec make the same power as a B18c using all stock parts?
