now, are you asking what engine you could put into the teg or what car you can put that RS engine into?
if you want to swap the motor on your RS you basically get any of the following that should bolt right in, except the H:
-B18C1
-B18C5
-H22
-B20(only worthwhile if you want a CRVtec)
or you can just slap a Vtec head on your current block.
