Beginning as the Quint Integra in 1985 in Japan, the Integra was shipped to the U.S. in 1986. In 1985, for trim models were produced, GS,
GSi, ZS, and LS, all having carburation except the injected GSi, hence the i standing four injection, believe it or not...In 1986 the GS was discontinued, and replaced with the
RSi, also injected...In 1987, the GS returned, the RSi discontinued and introduced were the
VX and RX models, both of which had a cross flow 12-valve
SOHC with
carburator...
