i think i have a 1.6L vtec motor in my 94 Honda civic and i was wondering do i have to put the same motor in it or can another motor plug right in i was thinking about ordering from tiger Japanese motors

 

you can swap just about any honda engine into just about any honda engine bay. Just depends how deep your pockets are...and what swap and power goals you want.

as for that site I have seen some bad thing come from them...
