I've got a 93' DX with the 1.5 D15B7 engine and 5 speed trans. I've been wanting to pump up the engine, but from what I've heard it seems to be better just to drop in a v-tech motor and then pump that motor up. I'm wanting to know if this is true and what engine would be the easiest/best drop in. Also what cars I could find such an engine in. or if i could do and engine & trans combo change. any ideas are appreciated.
