My place. I have an old Schwinn that I'd swap for your 240sx. j/k.
I agree w/ WDRacing. You're lacking details. What kinda swap are you looking for? SR20DET? LS1? Pinwheel + hamster? And as far as shops, it would help to know where you are located. Plus "best place" and "cheapest place" tend to be opposites.
