With this 1.5l conversion I used an X19 engine out of a 79, since 128's and X engines tilt at different angles I swapped the oil pan and pickup from the old 1.3l 128 engine which I mated to a 32/32 weber DMTR. This engine came with a one wire Marelli alternator so the  wiring got a little upgrade as well. I want the under hood business to remain stock in appearance.
