s5 swap options
 

i just got my first rx7 s5 roller
previous owner put in a turbo rear end and tranny from an s4
im wondering what a fairly inexpensive engine would cost me,
and what i might be looking for, for an easy swap

Is the rest of the car set up for a turbo?

the rest of the car is set up for a turbo, but i was told i could use something other than a turbo
