200cc engine displacment and 20 hp

Depends on where u r at, the 200SX in the states starts in 1979 to 1988(S110 from 79-83, S12 From 84-88), which had a few different engines ranging from a 1.8L to a 2.2L & was RWD & paved the way for the 240SX (S13 & S14). And from 1995 to 1998, the 200SX was basically a 2 door sentra, with a 1.6L or 2.0L engine & was FWD. There was no vehicle named 180SX in the United States.

In Japan a 180SX was a S13 Chassis Hatchback, & came initially with a CA18 & went to a SR20 in the later part of its life. There was no vehicle named a 200SX in Japan.

The the UK there was the 180SX & it came with a CA18DET & when it made its transition to the SR20DET, they renamed it the 200SX. And this car carried the named continually into the S14 chassis.
